在北京时间9月12日的新闻中，前底特律活塞队球员泰夏安·普林斯参加了《Knuckleheads》节目。
谈到2003年选秀时，普林斯表示：“我们都认为球队会选甜瓜，我们之前没见过米利西奇，而我们确实看到了甜瓜在大学夺冠。虽然我们球员没有说，但在我们心里都觉得选中甜瓜会很棒。
“当时管理层已经把我看成球队未来的小前锋，而奥库是很有天赋的球员，球队觉得最终他会以自由球员身份离开，所以需要选一个内线。”
2003年选秀大会，活塞在第2顺位选中米利西奇。2004年2月9日，开拓者将拉希德送至老鹰，换来沙里夫-阿卜杜-拉希姆和拉特利夫等。在亚特兰大待了10天，仅出战了1场比赛，拉希德又在一笔三方交易中被老鹰送往活塞。正是拉希德的到来，补足了活塞最后的夺冠拼图，在2004年总决赛中拉下不可一世的F4湖人，率活塞夺冠。

Washers are little, round, flat discs having a hole in the middle. They are made from different materials, including brass, stainless steel, carbon steel, and non-metallic materials like ceramic, phenolics, plastic, etc. Washers’ function is to facilitate the distribution of load over a relatively large area.
A washer placed between a surface and a screw act as a spacer, minimizing the effect of vibration produced by equipment or machine and preventing corrosion.
Washers are essential when coupling parts using bolts and nuts. Here is the purpose of washers.
Washers can be utilized as spacers. When we insert a threaded fastener into an object longer than its depth, the fastener protrudes from the rear of the object. For instance, when one tries to insert a 3-inch-deep fastener in a 2-inch-deep object, the 1-inch fastener sticks out the back of the object.
However, inserting a washer into the fastener before screwing it to the object helps prevent this protrusion. Therefore, it does this by creating padding, ensuring the fastener does not go too deep into the object. Also, washers compensate for slight variations in the spacing found between types of fasteners and parts, ensuring proper alignment.
Washers assist in spreading the load more equally across a broader surface. The risk of material deformation, damage, or failure is decreased by washers because they disperse the force produced by a nut or bolt. For instance, driving a screw into a softer material could result in cracks appearing on its surface. However, with washers, there is minimal damage tendency.
Washers in this category stop water and other liquids from entering and exiting. Seal washes are frequently applied in water pipelines and connectors to make a waterproof seal. Liquid-sealing washers are constructed of a flexible material, and this material choice ensures they press completely against the object’s surface.
Vibration absorption is a feature of some washer types. Washers in this category are mainly not metals. Instead, softer materials like plastic, rubber, or urethane are used to create them. These softer materials are better at absorbing vibrations than harder elements like metal.
Additionally, vibration-dampening washers help protect coupled parts from damage. This is especially true when one of two objects connected by a threaded fastener vibrates violently.
The nut or bolt head and the surface it is fastened to are separated by washers, which serve as a protective barrier. This preserves the material’s integrity and maintains the connected surfaces’ visual appeal by preventing marring, scratches, dents, and other damages.
Washer fasteners, especially those made from corrosion-resistant materials, offer additional protection against corrosion and rust. This is crucial in locations where prolonged exposure to moisture, strong chemicals, or other elements can deteriorate the fastening system.
Manufacturers use types of washers for making and coupling parts. Below are different washers and their uses.
Plain washers are the most popular kind. They disperse force and safeguard the item that the screw or nut is attached to. It also helps the screw or nut fit properly into a large hole. Plain washers in this category include:
The principal uses for these washers are in the woodworking industry. When a nut is tightened, the outside prongs of the washers feature square holes that prevent the accompanying bolt from spinning.
Flat washers have a hole in the center and are flat or disc-shaped. They are ideal for small head screws because they spread the weight across a wider surface.
Fender washers are bigger and have a tiny hole in the center. They can spread out the load across a broader region. These washers are primarily used in sheet metal manufacturing, automotive fenders, and plumbing industries.
Countersunk washers in this category often create a flush finish upon securing with a flat-head countersunk screw. This ability to catch countersunk fasteners is due to its sunken top.
Shoulder washer fasteners in this category come in various materials, including PTFE, fiberglass, metal, phenolic, and nylon. These shoulder-like shaped washers often serve as insulators for screws and wires.
A C-washer resembles a flat washer, but the primary difference is the hole cut from its center to form a C-shape. One primary advantage of this type of washer is that it is possible to adjust, remove or modify it without removing the fastener.
For machinery that vibrates vigorously while operating, spring washers are ideal. They move with vibrations, thus preventing them from being loose or unfastened because of their axial flexibility, consequently increasing the joint’s flexibility. There are different types of spring washers.
These washers, often called conical spring washers, are employed to maintain tension during the assembly’s thermal expansion and contraction. They can support large weights while deflecting only slightly.
A dome washer is renowned for having a large load capacity with minimal deflection. They also absorb excessive vibrations and flatten the surface.
In addition, they have ground curves that create a load-bearing surface that is flatter. It can be used everywhere. A crescent spring washer would be useful, although flattening the surface is also necessary.
Wave spring washers are curved in two directions and are typically employed as cushions or spacers. They can support a moderate amount of weight and guard against excessive wear on the surface.
Made using carbon steel, finger spring steel washers comprise three curved flanges. They help lessen vibration, skidding wear, additional wear, dampening, and noise on rotating parts.
Carbon steel is commonly used to make finger spring washers. They blend the wave washer’s predetermined load spots with the casing washer’s flexibility.
The crescent spring washer, also called curved spring washer, has a somewhat curved appearance that gives them a lighter pressure while maintaining flexibility. They have an extensive deflection range and can withstand extremely light loads.
These washers have linear load-deflection characteristics and offer uniform spring rates throughout the deflection range.
Lock washers are designed to help prevent the screws and nuts from rotating toward their loosening position. Consequently, this preserves them even during intense vibrations produced by the machine or equipment’s operation. In other words, they hold the fasteners that tend to loosen due to friction in place. The different types of lock washers include:
The split lock washer, commonly called a helical washer, is used to secure fasteners. They are non-continuous rings bent inward and outward in opposing directions. When this fastener is used to secure the bent, both ends of the bent flatten out and dig into the mating surface.
External tooth lock washers employ a teeth-structural action to keep the nut or screw head from coming undone. They function better with screws that have a larger head. The numerous teeth on their outer diameter bite into the surface to produce exceptional compression resistance, consequently ensuring they provide the highest level of torsional resistance.
On the inside diameter of the internal tooth locker are many teeth that prevent the bolt or nut head from loosening. They serve to dampen noise and shock while locking shallow-head fasteners into position.
Specialized washers do not fall expressly into any of the above categories. Here is their information.
Also referred to as K-lock nuts, these washers with built-in washers facilitate spinning. The assembly functions more efficiently, thanks to the nuts.
These washers are perfect to utilize while repairing or installing a tap because they are typically used in plumbing applications.
Typically used between bolts to prevent them from spinning, these washers are placed keyed washers typically find application in the automotive industry. These washers have an internal tab that prevents the automobile shaft from rotating. They also find use in chassis parts and cylinder heads.
Insulating shoulder washers are often made from nylon, peek, plastic, and other insulating materials. The best use for these washers is in the electrical sector, where they help isolate mounting screws from electrical current.
Gaskets, also known as O-rings, and made of rubber, come in different shapes and sizes depending on the purpose. It is a mechanical seal that fills the space between two or more surfaces in contact to prevent leaks and spills. In the automotive sector, their primary use is to slam shut oil and gas connectors and stop leaks.
Aside from rubber, gaskets can be made from light metals, such as aluminum, and other metals. These washers maintain a tight seal regardless of pressure and temperature, preventing gases and liquids from escaping.
Washers are made from different materials, including metal, plastic, and rubber. The type of material used in making a washer is often dependent on the material. For instance, metal washers are mostly used if great strength is required. When a tight seal and flexibility are required, rubber is the best material. For minor uses, plastic is ideal. Below are the materials used for making washers.
It’s good knowledge that rubber washers are made of synthetic rubber nitrile. Regarding sealing washers, this material and nylon have some similar qualities. These washers can effectively seal uneven surfaces since rubber is more flexible and pliable. However, rubber and nylon have the disadvantage of quickly distorting under strong compression forces, reducing the washer’s life span.
There are different types of metals and grades of metals used in making washers due to the different beneficial properties of these metal washers. Metal washers often form a powerful seal, preventing leaks and drips, especially for metal washers made from stainless steel, due to their corrosion resistance.
Asides from preventing leaks in some cases, metal washers like copper and other softer metals can help keep connections safe by reducing machine vibration.
Compared to metals, plastic washers made through injection molding are more affordable. Consider employing a plastic washer if your application doesn’t need excessive strength. Also, use a plastic washer when electrical isolation and vibration resistance are required.
Plastic washers are particularly well suited for electronics. While some come in different colors, you can also find clear plastic washers.
Machinists use two major washer size standards; SAE washers and USS flat washers. The SAE washers are usually thinner and smaller than the USS washers. Below is a washer types chart of both washer categories.
Washers come in different shapes, often dependent on their functionality. There are some washer shapes.
As their intended purpose, these washers have a precise, parallel plane between the bolt head and the nut face. Spherical washers automatically correct and balance the angular misalignment between the planes while guarding against bolt bending. Examples include fender, slotted, countersunk, and flat washers.
Compared to round washers, square washers have a higher surface area, which improves torque distribution. They help in corrosion resistance and rotation prevention.
Additionally, they are employed to restrict electrical current, vibration, and sound for usage in seismic applications. Washers in this category include flat, structural, and countersunk washers.
These washers are also known as insulator washers. They are non-metallic, often made of nylon. Shoulder washes typically come with a long or short barrel. They protect fasteners from moisture and dirt.
Usually made from metals, wave washers are often curved in two directions. They function primarily as spacers or cushions; when compressed, they help sustain loads and maintain fastener tension. An example is the wave washer.
Designed to slide in and out of position on a bolt without necessarily loosening it, C-washers find use as a retention device on a grooved shaft. They help keep components in place. Examples include the lock and slotted washer.
The ASTM F844 standard covers the widely used inch series flat washers. These flat washers are made with a bearing surface and utilized under bolt heads or bolt-like external threaded fasteners.
Spring lock washers from the inch series are available in ordinary, heavy, extra-duty, and high-collar varieties. It is constructed from stainless steel, 65Mn or #70 steel, or spring steel. For common applications, spring lock washers distribute the load over a larger area for some head designs and offer a hardened bearing surface to make up for acquired looseness between assembly component components.
Flat washers under DIN 125A specifications are made of sheet metal, have a smooth bearing surface, and go underneath the heads of nuts and bolts. Flat washers are often constructed of stainless steel and carbon steel.
A type of spring steel or other high-performance washers, stainless steel produced machinery component is the DIN6799 retention washer, often known as an E-Ring. It is used as an eccentric shaft with grooves for spring retention and is appropriate for transmitting axial forces.
When choosing a suitable washer for your project, here are some rules or factors to keep in mind to ensure you are choosing the right washer for your needs.
The first factor to consider when choosing a washer is the strength of the material you intend to use. When using a washer that is stronger than the base material could damage the base material. However, if it is difficult to find a washer with strength that matches the base material, it is best to use large-sized washers to avoid making indentations on the material. This is particularly true when working with fiberglass, rubber, and plastic materials.
The type of bolt you use should determine the type of washer too. It is best to match high-strength bolts to high-strength washers to ensure part and product stability following design for assembly principles. Also, ensure the bolted parts are similar, which means metal to metal or plastic to plastic. Bolting steel to rubber or plastic washer is not recommended.
It is best to consider environmental factors where the washer would be used. If the washer is exposed to the forces of weather and climate, then you might want to choose a washer made from materials resistant to corrosion. Also, consider galvanic corrosion between metals that are dissimilar to consideration, as it could affect the durability of the washer.

The washer is a flat plate in the form of a disc with a center hole. There are different washer types, ranging from flat to spring. They are utilized to distribute loads over a sizable area. It is mostly utilized for springs, spacers, pre-loading screws, and vibration reduction. Not sure what kind of washer you need? Contact WayKen today.
Why do we use washers with screws?
Without a washer for a screw, a screw’s threads could pierce the material during tightening, damaging the joint’s bearing surface. Washer screws help share the weight.
What’s different between spring washers and flat washers?
While spring washers are curved, plain washers are flat. The majority of applications employ plain washers. Spring washers are suggested for vibrating machinery and parts because they offer an axial load to counter vibrations and keep fasteners from loosening.
How to use washers in a fast way?
First, screw the bolt into the washer. Afterward, insert the washer and bolt into the mounting hole. Then start twisting the bolt head with the correspondingly sized wrench. Once the head of the bolt touches the washer, tighten it down to it.

Are you in need of some motivation for writing? Or do you feel like you need to escape your crazy every day life for a bit? Then we may have found the perfect thing for you: Camp NaNoWriMo
In an earlier article we have already talked about National Novel Writing Month, what the positive effects of partaking are, and how you can start your very own personal NaNoWriMo. This event takes place over the whole November, and this is where the difference to Camp NaNoWriMo lies. Take one month of your life to write a novel or collection of short stories, and start in April or July instead!
So, what is this “Camp” all about? Much like when participating in the National Novel Writing Month, you will get encouragement and motivation, support and helpful resources for your novel writing. You can thoroughly plan your novel, track the progress, and even create a community of like minded writers to exchange ideas, advice, and encouragements.
Instead of having the fixed time period of November, however, the camp-approach is a lot more open-edned, giving you the chance to really choose a time where you can concentrate on your writing. Furthermore, it’s not only about writing your 50.000 word novel. Next to Camp sessions in April and July, you can work on non-novel projects as well. Furthermore, word goals of more than 50.000 words are welcome as well.
The camp idea behind Camp NaNoWriMo may suggest that people will have to actively come together to participate. However, it is more of an online camp that is simply there to give you the impression of a getaway environment where you can flee from every day life and stress, and meet up with like-minded people. Much like one of the summer camps you loved to go to as a kid.
Furthermore, Camp NanoWriMo gives you the opportunity to set up a so-called cabin. Up to 12 “campers” can share one cabin. Based on the preferences you select for yourself in your “Cabin settings”, you will be assigned to a cabin where you can communicate with the other Campers and share encouragement and writing tips. The assignment of the perfect cabin for you depends, among others, on your age group, genre you are writing in, and word count goal. Of course, you can also create a private cabin in which no one can be sorted into randomly. Only people you invite can join your cabin.
Motivated? Then sign up to participate in the next Camp session! It starts in July already!
But do not forget about the basic writing tips and advice, and take care that your writing has the correct grammar and spelling as well!

Today, we are going to learn all about the term “Caught Red Handed.” This is a phrase or term, that people often use. It is used when referring to someone who has been caught dead right. Or someone who has been caught doing something wrong with sufficient evidence for all to see.
But where exactly did this idiom come from? What country did it originate from? Who started using the term and coined to mean getting caught completely without doubt?
According to history, the term ‘caught red handed’ originated in Scotland. It is said to have its roots there as early as the 1400s. This phrased was used around the 15th century, for people who were caught with ‘blood on their hands.’ But, the phrases used were ‘redhand’ or ‘red hand.’ The Scottish Acts of Parliament of James I, are the first documented instances of the term ‘red hand’ being used.’ That took place back in the year 1432.
As time went by, the idiom continued to be used more and more. In fact, in Scotland, it was ultimately used in several legal proceedings. During these instances, it was almost always in reference to someone who was caught in the act of doing something criminal. Later on, the expression began to morph into ‘red handed’ from the idiom ‘red hand.’ Sir Walter Scott used the term in his work Ivanhoe which was written in the 19th century. That was the first instance where the phrase was ever documented to begin to change.
Perhaps you may be interested in knowing Punctuation and How People Began To Use It In English
In the early 1400s, there was a lot of poaching going on all over. Those people in Scotland who were caught poaching an animal, usually had blood on their hands. That is how the term became popular. It was those who were stealing or poaching animals, who were caught ‘red handed’ by others. Soon after, Sir Walter Scott made the phrase more popular and a larger audience began to use it.
Today, the term caught red handed is very popular. There was even a Television show, bearing the same name. It was aired during the years 2012 to 2013, on the American reality TV channel, TruTV. Countless of people around the world often use the term as well. Each time, they use it when they refer to someone who has been caught stealing or doing something wrong. This day, no one wants to be accused of being caught red handed.
Don’t miss finding out Where Did The Term Nicknames Come From?
Some people debate whether or not the term red handed should contain a hyphen on it. In truth, in order for it to be correctly and properly rendered, it should be done with a hyphen. That means ‘red-handed’ is the correct way to use it. But, you can still use it without the hyphen in either case.

您在使用 Google Ads（谷歌竞价广告） 时可能遇到的最紧张的情况之一是您无法立即解释广告效果突然变化。除此之外，您的老板或客户会不断提醒，要求解释他们在网站上的访问量或销售额下降的原因。所有这些都创造了一个非常紧张的环境。
凭借 10 年的谷歌竞价广告的经验，尝试分析突然的性能变化，我最大的收获是您需要更深入地研究。随着时间的推移，仅仅在“低维度”标签中查看您的整体谷歌广告系列效果是不够的。您需要深入了解实际的Google广告组并深入了解细节。在分析 4-5 个效果下降的广告组后，您通常会看到一种模式。
谷歌官方对突如起来的变化解释是：
如果您的广告或关键字未能获得预期的展示次数，原因可能非常简单。用户使用与您的关键字相关的字词进行搜索的次数，以及您的关键字能否有效触发您的广告（而不是竞争对手的广告），都会影响广告所获得的展示次数。网络流量、客户行为和网络内容的不断变化也都会使您的展示次数产生正常波动。
竞争对手作出的广告决策也可能会影响您的展示次数。每当新的竞争对手进入市场，或您当前的竞争对手调整了现有帐号的内容，您的广告所获得的展示次数就可能会发生变动。例如，您最主要的竞争对手可能提高了出价，导致您的广告无法在搜索结果首页上展示，您所获得的展示次数也因此而减少。许多广告展示都来自于在 Google 搜索结果首页上展示的广告，因此如果您提高出价，就可以增加您的广告在首页进行展示的机会，从而获得更多展示次数。
临时性活动也可能会产生较大影响。例如，节假日或热点新闻话题都可能会极大地影响您所获得的展示次数和点击次数！在节假日前后，宣传装饰品和节假日植物的广告客户可能会遇到网站访问者数量大幅变化的情况。热门名人对某服装品牌的代言也属于这种情况；在这种情况下，宣传该品牌的广告客户可能会获得更多的展示次数。
遇到点击量较低时最常见的情况之一是您的点击率也会下降。您基本上有两个指标会影响您的点击次数：
在这种情况下，如果您的点击率也下降了，我们将调查点击量下降的 3 个原因：
如果您在点击量减少时更改了谷歌广告设置，那么这通常是原因。许多广告商在制作新的广告变体时并没有考虑到。
在 Google Ads 中测试广告的过程与常规 A/B 测试完全相同。您需要有一个对照广告，它能够告诉您新广告的效果是好于还是差于您的基准。我经常在我认为测试它们是浪费时间的地方制作广告。它们显然写得更好，但我仍然决定测试它们。有几次我被证明是错误的，我能够快速暂停新广告并恢复我们之前的广告系列表现。
如果您最近更改了广告并随后遇到了较低的点击率，我建议您重新启动旧广告并进行测试，看看新广告是否有问题。
如果平均而言，您的广告排名为 2.3，但突然发现自己的平均排名为 3.2，您将看到点击量急剧下降。随着您在 Google 中的排名下降，您的点击率会降低很多。
广告排名下降的原因可能有很多，而您获得的点击次数却减少了。最常见的原因是：
根据点击率下降背后的原因，您将需要开始不同的任务。
如果您的点击量开始下降，您的竞争对手会简单地开始出价超过您，以至于您无法继续捍卫相同的广告位置，从而导致点击量降低。
当您的老板或客户尖叫着要求更多点击时，不要哀叹。他们可能无法更全面地了解您降低出价的原因。通常，您可以向他们解释您降低了出价，或者您的竞争对手变得更加激进，并制定了从 AdWords 中获得更多收益的计划。
点击率低的原因之一是竞争对手开始积极促销。如果您以大致相同的价格销售相同的产品并提供相同的好处，那么您无疑会受到点击量的波动，具体取决于竞争对手的促销活动的积极程度。
如果您的点击率正在下降并且您的点击量正在下降 – 请记住使用广告预览工具搜索您的关键字，并确定您的广告是否仍然是页面上最具吸引力的。
如果您的点击率与往常一样，但您的点击次数有所减少，则原因可能只有一件事：展示次数减少。
您的展示次数较低可能有多种原因，但以下是一些最常见的情况：
季节性是许多行业的一个重要领域。即使是季节性“证明”的企业也会在全年对其产品的兴趣出现波动。
背包在“返校”季节卖得非常好，而玩具在圣诞节前后的需求量大幅增加（几乎所有其他消费品都一样）。
在您开始深入了解您的Google 广告系列之前，请调查一下季节性是否会导致您的展示率较低。展示次数只是表示“搜索次数”的另一种方式，因此当展示次数下降时，对您的关键字的搜索量也会减少。
如果您更改了广告系列的匹配类型策略或仅更改了一些主要关键字，您的展示次数将会出现波动。
假设您暂停了所有广泛匹配修饰符关键字，而是选择更多地词组匹配和完全匹配。在几乎所有情况下，这都会减少您帐户的总体展示，从而降低您的点击量。
同样，这不一定是坏事。如果您通过选择专注于词组匹配和完全匹配来将预算花费在更相关的搜索词上，那么这将是一个非常健康的实施策略。如果您同时看到转化率下降，那么就需要进一步调整。
这对某些人来说可能很明显，但如果您最近暂停了某些关键字，您的展示次数也会减少。我见过客户和初级谷歌竞价优化经理根本不明白为什么他们的点击量下降了。
快速访问Google AdWords 中的更改历史记录工具后发现，一些高容量关键字已被暂停。当您遇到点击量较低时，可能很容易跳到一些更复杂的问题，但有时答案就在您的眼前。
一旦您开始向 AdWords 广告系列添加否定关键字，就很容易添加过于宽泛的否定关键字。过于宽泛的否定关键字会阻止他们不打算阻止的搜索。
如果您正在为销售果汁机的保健品商店做广告，您可能会看到对 Omega 鱼油的搜索。为了确保您从未收到来自对欧米茄油、鱼油等的搜索的点击，您添加了否定关键字。
展示次数减少的另一个原因是质量得分较低。您可能仍然拥有相同的点击率，但由于多个关键字的质量得分较低，您的总体展示次数有所下降。
您的质量得分越低，您需要出价越高才能保持与以前相同的位置。如果您的质量得分下降得足够多，您将开始看到低于首页出价的关键字。这意味着您的关键字只会在其他广告商的预算用完时才会显示，或者当 Google 轮换一些当前的广告商以便向重复搜索者展示更多样化的广告集时。
如果您的质量得分较低，您需要做几件事才能恢复原来的质量得分。但是，您需要检查的第一件事是您是否拥有质量得分成功的正确框架。
如果您最近提高了质量得分或出价，您很可能会获得更高的广告排名，从而获得更高的点击率。
随着点击率的提高，您实际上开始在一天中更早地获得更多点击，从而在一天结束之前达到您的预算。当出价增加超过预算可以承受时，通常会出现这种情况。
假设您之前为每次点击支付 1 美元，并在 100 美元的预算下每天达到 100 次点击。在为某些产生低于目标每次转化费用的转化的关键字提高出价后，现在您的平均每次点击费用为 1.2 美元。因此，您只能预算 80 次点击。根据您的每次点击费用增加，您可能会看到点击量发生很大变化。
继续前面的案例，让我们更深入地了解提高质量得分如何意味着更少的点击次数。在下一个示例中，我们假设以下内容：
关键字 A 的质量得分为 3/10，平均。排名 6.0 每天 25 次点击和 5 美元的每次点击费用 = 125 美元的支出
关键字 B 的质量得分为 7/10，平均。排名 2.1、每天 200 次点击和 1 美元的每次点击费用 = 200 美元的支出
总共花费了 325 美元用于 225 次点击。您的预算正好是 325 美元，所以您一天都吃不完。
假设您的关键字 A 的质量得分提高到 7/10。关键字 A 比关键字 B 具有更多竞争，因此即使其质量得分较高，您也会看到关键字 A 的 CPC 较高。
随着关键字 A 的质量得分提高且出价保持不变，关键字 A 将达到排名 2.0。这意味着您的点击率会更高。你可以很容易地期望从 1% 增加到 10%。因此，您将获得比以前多 10 倍的点击次数。
但是，我们仍然只有 325 美元的预算。在我们从 1 美元 CPC 关键字获得大部分点击之前，我们现在必须平均分配 1 美元 CPC 关键字和 5 美元 CPC 关键字之间的点击：
325 美元 = 每个关键字 162.5 美元
162.5 美元 / 5 美元 = 32 次点击
162.5 美元 / 1 美元 = 162 次点击
325 美元的费用现在突然等于 194 次点击。仅仅因为我们的质量得分提高了，点击量就下降了 14%。我敢打赌你没有预见到这一点。
每当您的 Google Ads 效果发生变化时，深入挖掘以了解实际情况至关重要。如果您花时间分析您的数据，您通常会发现导致您的广告系列表现停滞不前的隐藏原因。有了这些信息，您就可以采取适当的措施来提高您的谷歌竞价效果。
我们建议您还像以前一样监控您的广告效果。Google 即搜即得既可能会提高您的整体展示次数水平，也可能会使之有所降低。不过，由于 Google 即搜即得可以帮助用户使用与其所需内容更为接近的字词进行搜索，因此，它应该可以提高您获得的点击的质量。这样，您的广告系列的整体效果也会随之改善。

在日常生活中，打印机已经成为我们处理文件、打印资料的重要工具。当惠普打印机突然显示设备已离线或显示脱机状态，该怎么办呢？下面就为大家提供一些解决方法，帮助你快速恢复打印机的正常工作状态。
首先，由于网络连接问题通常是导致打印机离线的主要原因，我们需要确保打印机与Wi-Fi网络连接稳定。请检查打印机是否连接到正确的网络，并尝试重启路由器。如果打印机是通过无线网络或以太网电缆连接的，还可以尝试通过打印机控制面板或打印机管理器检查网络设置，确保它正在连接正确的网络。
如果网络连接没有问题，但打印机仍然显示离线，您可以尝试重新添加打印机。在Windows系统中，可以通过“设置”>“设备”>“打印机和扫描仪”>“添加打印机或扫描仪”来执行此操作。
驱动程序是打印机与计算机之间进行通信的重要组成部分。如果驱动程序已损坏或过时，可能会导致打印机离线。
1、可下载安装“打印机卫士”软件，它能自动识别你的打印机型号，智能推荐并安装最适合的驱动程序，减少用户手动查找的繁琐。

2、在打印机正常连接到电脑的前提下，打开打印机卫士，点击“立即检测”。
3、扫描完成了，点击“一键修复”选项，它就会开始下载并安装与你的打印机相匹配的驱动程序。
如果您使用的是HP Smart应用程序，可以利用其内置的诊断和修复工具来解决打印机问题。在Windows和macOS系统中，打开HP Smart应用程序，点击诊断和修复图标，然后按照提示进行操作。该工具可以帮助您快速识别并解决打印机连接和打印问题。
请确保打印机被设置为默认打印机，并检查其是否有任何错误状态。如果打印机存在硬件故障，如墨盒耗尽或打印头堵塞，也可能导致设备离线。此时，您需要更换墨盒或清洗打印头。
在尝试了以上所有方法后，如果打印机仍然离线，您可以尝试重启打印机和电脑。关闭打印机和电脑，等待一段时间后再次开启，然后检查打印机是否恢复正常工作。
