气孔

The quality assessment of brazed joint of aluminum matrix composites was performed by the advanced ultrasonic imaging technology .

超声成像技术能反映出铝基复合材料钎焊界面的接合状态，可检测出气孔、氧化膜夹杂和未钎透缺陷，为铝基复合材料钎焊的研究提供了有效的检测手段。

Comparing with diploid, the growing rate of tetraploid plants was slow and leaves became bigger, thicker, dark green and crimpled. The stomata density of tetraploid plants was reduced, but the guard cell of stomata became bigger and the chloroplast number in guard cells was increased.

与二倍体相比，四倍体表现为：生长变缓；叶片增大、皱缩和变厚、叶形指数减小；叶片保卫细胞增大，气孔密度降低，叶绿体数目增加，叶色加深。

In the other hand, graphite carbon and SiC oxidizing produce CO、SiO〓 and in the same time CO separates graphite carbon partially, this effect will decrease decarburizing rate and corrosion rate for Al〓O〓-SiC-C brick. TiO〓 and SiO〓 protective layer forming and separating graphite carbon are the main factor of resistance smelting reduction molten slag-iron to corrode and the main feature of corrosion process.

Al〓O〓-C-SiC砖在侵蚀过程中，由于SiC氧化后产生CO，SiO，并析出碳和降低耐火材料气孔率及氧化形成的SiO〓成为保护膜，使熔体对耐火材料的侵蚀能力降低，这两种耐火材料的侵蚀速度都是随着使用时间延长，耐火材料侵蚀速度逐渐降低。

Frying and defatting parameters will affect the fat content and the quality of food during frying. Scholars put forward different opinions.

得出了脂肪的吸收既受原料中初始水分含量的影响，又与水分蒸发留下的气孔的大小和分布相关。

Blackheads are not caused by dirt but by the discoloring effect of air on the fatty material in the clogged pore.

blackheads不褪色造成的影响，但污垢的脂肪物质在空气孔阻塞。

These results suggest that the decrease of Pn under sub-high temperature was maybe mainly induced by non-stoma limiting factors,and the earlier the plants were treated by sub-high temperature after they effloresced,the worse the photosynthesis the plants were.

认为番茄叶片Pn的降低主要是由非气孔限制因素引起的。

The being used plating technologies are not satisfied because that pinholes and cracks appear in electrodeposits due to hydrogen absorption.

但现在的电沉积工艺因吸氢严重致使镀层含有大量的气孔和裂纹，不能满足要求。

With the porous hulls of other grains, steam easily passes through, so no significant pressure is produced.

其他的谷物的外壳是有气孔，水蒸气非常容易穿过，不会产生压力。

Don't inlet water at this time, and pour the water when inletting it in case its expansion blocks the holes.

注意此时不要加水，加水后请放出少量水，以免膨胀溢流到回水管内，堵寒透气孔。

Finally absorb hole and exhaust hole of the compressor are designed on the base of the joggling theory and the requested air pressure.

然后，根据压力要求和啮合原理，设计计算出吸排气孔口的大小和位置。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
