气孔

Plants adapted to blown sand stress through different ways which included ground biomass decrease and leaf roll, cutin and cell wall thicking and stomatal depression, all of these could decline water losses.

在强风沙流吹袭特别是在多次吹袭下，气孔下陷加剧，抑制了叶肉细胞向大气蒸腾水分。

The stomatal guard cells ofTI line are closure.

4T，代烟草叶下表皮保卫细胞气孔开度比对照的小。

It brings no influence to your common operation but good effect of heat-radiating with riser vent while protecting your machine.

设有透气孔，能在保护您机器的同时起到良好的散热效果。

The production cost of new chromite powder compound coatings is half of zircon coatings. The surfaces of castings that are produced used new chromite powder compound coatings are smooth without adhering sand and gas- hore.

例。新型铬铁矿粉复合涂料生产成本仅约锆英粉涂料的二分之一，可代替价格昂贵的锆英粉涂料生产无粘砂，气孔等缺陷，表面光洁的合金钢和碳钢铸件。

Based on the analysis of formation mechanism of shrinkage, dispersed shrinkage, gas cavity and blow hole shrinkage in the brake hub castings of Santana car, some methods are put forward to solve these problems.

本文在对桑塔纳轿车后制动毂的缩松、缩孔、气孔、气缩孔等孔洞类缺陷进行机理分析的基础上，提出了一些解决的措施，并在实际生产中取得了明显的效

The pressure rerief vent will operate in normal conditions, with no short mode and dangerous condition such as flames ignitions or dispersion of pieces of the capacitor and /or case

卸压排气孔将工作于正常条件，需为没有短路状态及危险状态，如火焰燃点或容器及/或机箱解体。

The inductions of stomatal closure by NO were enhanced by higher concerntration of Ca2+,and the role of NO appears to demonstrate to be obvious time and concentration effects.

NO能够诱导桐花树气孔的快速关闭，并且NO的作用表现出明显的时间效应与浓度效应。

Using high frequency induction brazing and TiZrNiCu filler metal, the shear strengths of the joints were low. The maximum shear strengh was only 102.1MPa, which was lower than the maximum strength of vacuum brazing. The reasons may be that excessive intermetallics, holes and oxidation existed in the joint. So TiZrNiCu filler metal isn't fit for non-vacuum brazing.The stress variation, stress distribution and crack-sensitive regions during the cooling process of brazing have been studied by Marc non-linear software.

采用气体保护高频感应加热、TiZrNiCu钎料钎焊时，接头的强度普遍偏低，最高的剪切强度只有102.1MPa，远远低于辐射加热真空钎焊的强度，其原因是接头中局部生成了过量的金属间化合物，且产生氧化，接头中含有较多的气孔等影响了接头强度，因此可以认为TiZrNiCu钎料不适合在非真空条件下的钎焊。

It may be a modified stoma with the guard cells permanently open so that water is lost passively by hydrostatic pressure , as in sea lavenders, or a glandular hair from which water is actively secreted, as in runner bean.

这可能是由于气孔的保卫细胞永久张开而使水分在静水力的作用下被动排出，比如海薰衣草；也可能是由腺毛主动分泌水分到外部，比如红花菜豆。

Gaseous excretion takes place by diffusion through the stomata and lenticels.

气体通过气孔或皮孔释放的方式排出。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
