气孔的

Rising jet fountains, which are inspired by natural geysers and the rocky ocean blowholes of Hawaii and Iceland, are the most dramatic, and some might say the most flamboyant.

喷泉喷射上升，这是自然喷泉和夏威夷和冰岛海洋岩石气孔启发，是最具戏剧性的，有些可以说是最华丽的。

The presence of small blowholes (2-4#m), caused by escaping volatiles, is evident on the rather rough surface of these chars.

这些半焦的粗糙表面明显有挥发物逃逸时造成的小气孔（2-4微米）。

A stoma nurse is a qualified nurse specially trained to assist people who have had a colostomy operation and whose bowel excretions must be emptied into a bag.

一气孔护士是一个合格的护士，受过专门训练，以协助人们谁了结肠造口的运作和其肠道排泄，必须掏空成袋。

It is home to the world's largest consentration of geysers, such as Old Faithful Geyser, hot springs, mud pots, fumaroles, and travertine terraces.

它是世界上最大的consentration的喷泉，如老忠实喷泉，温泉，泥盆，喷气孔，和石灰梯田。

If you don't have the option of venting to the outside or if space is a premium, a vent free gas stove will work.

如果你并没有选择把通风口放到外面，或者你的空间是优质的，只要保持通气孔畅通，煤气炉就能正常运行。

Results show that the mullite grogs can be gained by the method at 1700℃ as long as the control of the chemical composition of ingredients(content of Al2O3 and ratio of Al2O3/ SiO2 ,etc.) with apparent porosity＜2.5% and bulk density≥2.75g/cm3; the heating process can be divided three stages, which are formation of primary mullite, secondary mullitization stage and liquid phase sintering stage.Key words bauxite, coal gangue, mullite grogs

结果表明，只要控制好混合料的化学组成（Al2O3含量、Al2O3/SiO2比等），就可采用此工艺制备出莫来石料，其烧结温度为1700℃，所得莫来石料的显气孔率大于2.5%、体积密度大于或等于2.75g/cm3；加热过程可分为一次莫来石形成、二次莫来石化和液相烧结3个阶段。

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。

Mechanisms and significance of microfracture s generated by microwave heating in sandstone reservoirs;2. There are many kinds of microfracture s which play an impor- tant part in connection of the pores in a reservoir and denudation of vugs,and enhancing reservoir permeability.

Y气田Z组火山岩储层孔隙结构复杂，基质孔隙间连通程度差，属于典型的低孔低渗储层；微裂缝种类多，在连通储层气孔和溶蚀孔洞、增强储层渗透性方面起着非常重要的作用，但识别和评价相当困难。

The study results showed that the porosity, pore size, pore distribution and crush strength can be adjusted by the alternation of addition and powder size of pore-forming agent, the variating of addition of binding admixture, sintering temperature, holding time, forming method.

研究发现，改变成孔剂的加入量、粒径大小，粘结剂的加入量，坯料颗粒大小、成型方式，烧成温度、保温时间等方法可以调节样品气孔率、孔直径、孔径分布、压碎强度。

Cd inhibited the absorption of Mg and Mn in roots. However, Cd could stimulate the absorption of Fe in roots. Moreover, Cd inhibited the absorption and utilization Mg, Mn and Fe in leaves. 4. Cd inhibited the photosynthesis of Populus clones. Cd showed no significant inhibition to net photosynthesis rate, stomal conductivity and transpiration rate versus the control, under 10μM Cd treatment.

Cd胁迫还对杨树光合作用产生影响，低浓度Cd对杨树光合速率无影响，中高浓度Cd对杨树净光合速率、气孔导度和蒸腾速率等具有抑制作用，而且随着处理时间的延长和Cd胁迫浓度的提高而逐渐加大。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
