想要获得某个（或某几个）分类下的全部标签吗？下面的方法一定对你有用。

将以下代码粘贴到functions.php中：

function get_category_tags($args) {
    global $wpdb;
    $tags = $wpdb->get_results
    ("
        SELECT DISTINCT terms2.term_id as tag_id, terms2.name as tag_name, null as tag_link
        FROM
            wp_posts as p1
            LEFT JOIN wp_term_relationships as r1 ON p1.ID = r1.object_ID
            LEFT JOIN wp_term_taxonomy as t1 ON r1.term_taxonomy_id = t1.term_taxonomy_id
            LEFT JOIN wp_terms as terms1 ON t1.term_id = terms1.term_id,

            wp_posts as p2
            LEFT JOIN wp_term_relationships as r2 ON p2.ID = r2.object_ID
            LEFT JOIN wp_term_taxonomy as t2 ON r2.term_taxonomy_id = t2.term_taxonomy_id
            LEFT JOIN wp_terms as terms2 ON t2.term_id = terms2.term_id
        WHERE
            t1.taxonomy = 'category' AND p1.post_status = 'publish' AND terms1.term_id IN (".$args['categories'].") AND
            t2.taxonomy = 'post_tag' AND p2.post_status = 'publish'
            AND p1.ID = p2.ID
        ORDER by tag_name
    ");
    $count = 0;
    foreach ($tags as $tag) {
        $tags[$count]->tag_link = get_tag_link($tag->tag_id);
        $count++;
    }
    return $tags;
}

然后你就可以在模板中使用这个函数了：

$args = array('categories' => '12,13,14');
$tags = get_category_tags($args);

Zap! Peach Ice Tea is a mixture of soft peaches and loose tea leaves, perfect for a peaceful day in the garden.

Zap! Nic Salts are best suited to Vape Starter Kits (Mouth to Lung) and Pod Vape Kits.

Nic Salts are extracted directly from the natural tobacco leaf, versus traditionally being made using a form of artificial nicotine called ‘free base’.

Freebase nicotine can be quite harsh on the throat and can cause discomfort for some vapers. Nic salts are absorbed into the body far quicker than standard e-liquid, so it provides a much quicker hit to keep your nicotine cravings at bay.

In addition to this, nic salts take away that harsh throaty aftertaste as they stay smooth even after being heated by your vaping device.

LED technology for UV curing of wood flooring coatings has a high potential to replace the conventional mercury vapour lamp in the future. It offers the possibility of making a product more sustainable over its entire life cycle.

In a recently published paper, the applicability of LED technology for industrial wood flooring coatings was investigated. The comparison of LED and mercury vapour lamps in terms of the radiation energy generated shows that the LED lamp is weaker. Nevertheless, the irradiation of the LED lamp at low belt speeds is sufficient to ensure crosslinking of UV coatings. From a selection of seven photoinitiators, two were identified that are suitable for use in LED coatings. It was also shown that these photoinitiators can be used in future in quantities close to the application.

LED technology suitable for industrial wood flooring coating

By using a suitable oxygen absorber, oxygen inhibition could be counteracted. This is a known challenge in LED curing. The formulations combining the two suitable photoinitiators and the determined oxygen absorber produced promising surface results. The application was similar to the industrial process on wood flooring. The results show that LED technology is suitable for industrial wood flooring coating. However, further development work is to follow, dealing with the optimisation of the coating components, the investigation of further LED lamps and the complete elimination of surface tackiness.

The study was conducted as a bachelor’s thesis by Melina Zernickel at Esslingen University of Applied Sciences. It is subject to a lock-up period until July 7, 2027.

The BHS AeroMaXX technology from Voith is a clever but simple and, most importantly, reliable solution that considerably increases the efficiency on the one hand and reduces oil consumption on the other hand. It was possible to reduce both the power loss and the previous lubrication and cooling oil volume by 30%. In each case, two components are equally important with respect to this considerable energy gain:

Optimized sleeve bearings on the pinion shaft:

In addition to the inner housing, BHS AeroMaXX technology comprises the Voith optimized BHS EcoMax bearing for the high-speed shaft. The basis of the BHS EcoMax sleeve bearing is formed by the specially-contoured offset sleeve bearings. Their running geometry and physical properties have been modified to obtain improved sliding behavior with reduced oil volume.

An inner housing encapsulated from the gear set:

The BHS AeroMaXX technology is distinguished by its modular inner housing that fits optimally into the gear unit housing. The steel-welded inner housing fits closely to the gear set and effects a separation between the absolutely-required lubrication oil volume and dissipation of the generated thermal energy. The low volume of lubrication oil reduces the windage losses due to the swirled oil-air mixture and as a result of oil squeezing in the gear mesh. The cooling oil volume that is applied to the external surface of the BHS AeroMaXX inner housing dissipates the heat transferred to the bottom of the gear unit in a controlled manner.

The savings potential is considerable, starting at a pitch line velocity of approximately 120 m/s and grows exponentially with increasing speed. Furthermore, it is possible to implement both components separately from one another.

The self-lubricating Minuteman Series composite bearings can handle 10 times the load, has a very low coefficient of friction, dampen vibrations, tolerates shock, and are lower in cost than conventional linear ball bearings. These composite bearings can be submerged, washed down with water, high-pressure steam, or chemicals, and can operate in harsh, abrasive, and contaminated
environments.

Designers specifying a Minuteman TM M-SRBT Twin Pillow Block Linear Rail Assemblies can select from seven different shaft sizes from 0.500-in. to 2.000-in. of either RC60 case hardened steel or 303 stainless steel rail guides in lengths to 12-ft.

As composite bearings are in 100% contact with the shaft there is no place for contaminates to collect and these bearings will not score aluminum shafting.

LM76 manufacturers a broad variety of bearings and shafting that can easily be integrated into new and existing applications. The bearing options include Self-lubricating FDA & USDA-compliant Teflon composite bearings in a 304 stainless steel shell, and lower-cost bearings with a ceramic-coated shell and FDA & USDA compliant liner. Bearings are available in closed
and open configurations, and are drop-in replacements for all-inch-sized linear ball bearings.

Description

DURANIT®- ideal compressive strength for maximum operational reliability. Processes in which catalyst calipers are used in accordance with international specifications cover a whole range of thermal and catalytic transformations of the substance: Duranit® inert balls and other forms can also be used for other purposes, for example, in high-temperature filtration to separate solid and liquid particles from hot exhaust gases.
Applications: alkylation, catalytic reforming, dehydrogenation, hydrotreating, desulfurization, isomerization, catalytic cracking, power forming, catalytic conversion, thermal cracking, catalytic oxidation and other processes.
The extremely high compressive strength of the DURANIT® X500 balls guarantees a high degree of safety and reliability, for example, to avoid problems when filling the reactor and thereby save unnecessary costs. VFF recommends that international reactor filling requirements be met to protect the product and plant from unnecessary negative impacts.

A recently published paper highlights currrent advances in the field of UV cured powder coatings and desscribes photoinitiators and reaction mechanisms during the UV curing process.

Powder coating systems are becoming more and more popular due to their unique properties. Nowadays, the ecological aspect is important and powder systems meet the following requirements: Powder systems do not contain VOC and they are more productive than liquid systems.

Modifications of old powder systems and development of new ones stem from the need to replace liquid systems and extend the application of powder systems. UV-curable powder coatings present some new possibilities for the curing of heat sensitive substrates and offer more advantages compared to thermally cured powder coatings. UV-curing can be performed at lower temperatures than possible by thermally activated systems.

UV-curable powder coatings

A recently published paper reviews the most recent advances in the field of ultraviolet cured powder coatings. The selected chemical structures of the resins (unsaturated polyester, urethane acrylates, acrylate and methacrylate resins, epoxy oligomers, polyamides and hyperbranched polymers) photoinitiators and additives used in formulation of UV-curable powder coatings are presented.

The physical properties and rheological behavior of the resin depending on their chemical structure, molecular weight, amorphous and crystalline structure as well as their influence on properties of crosslinked coatings are described. The curing conditions used in UV curing technology and its advantages such as fast curing and high efficiency, low capital investment, solvent elimination, low cost and energy consumption are also presented.

The review has been published in Progress in Organic Coatings, Volume 158, September 2021.
