Like human skin, soil has holes that are called pore. 就像人类的皮肤一样,土壤也有小孔被叫做气孔。
The sweat leaves your skin through tiny holes called pores. 汗液通过皮肤上的小孔即毛孔排放出来。
Lesions develop that eat bone, cartilage, skin and soft tissue, leaving victims with gaping holes where their lips or noses should be. 疾病引发的损害侵蚀骨骼、软骨、皮肤和软组织,造成患者的嘴唇或鼻子部位溃烂为空洞。
RESULTS: False Houpurunnan have transverse skin holes and no oil trace was found. 结果:伪品薄叶润楠可见横向皮孔多突起,油痕不明显。
By establishing the model of skin factor calculating for Perforation Gravel Pack technology, the influence of the perforation parameters such as the depth, diameter and density of perforated holes etc. 文章在通过建立射孔砾石充填井表皮系数计算模型的基础上,分析了射孔砾石充填井的孔深、孔径、孔密等射孔参数对表皮系数的影响及其程度。
The results show that the cooling configuration is an efficient cooling mode for the aerodynamic heating skin. The cooling effectiveness would be enhanced with a suitable mass-flux and better film holes arrangement. 研究结果表明,该冷却结构对高马赫数飞行条件下的气动加热表面具有较好的冷却效果;适当增大通道冷却结构的液氮入口质量流量和合理布置气膜孔能改善表面的冷却效果。
