The mean bulk momentum transfer coefficient cd and bulk sensible heat transfer coefficient ch is 3 . 37 * 10 - 3 and 4 . 47 * 10 - 3 , which is slightly larger than that above desert gobi and grassland of plain and little than that above plateau . on one hand , the more unstable atmosphere is , the larger bulk transfer coefficients are under unstable conditions , on the other hand , and bulk transfer coefficients decrease as wind speed increases 动量和感热总体输送系数的平均值分别为3 . 37 * 10 ~ ( - 3 )和4 . 47 * 10 ~ ( - 3 ) ，略高于沙漠、戈硕士学位论文:半干早雨养农业区陆面过程观测试验研究壁及平原草地的值，而低于高原的值;在不稳定时，层结越不稳定，总体输送系数也越大，并且随风速的增加而减小。
In this distress the mate of our vessel lays hold of the boat , and with the help of the rest of the men , they got her flung over the ship s - side , and getting all into her , let go , and committed our selves being eleven in number , to god s merry , and the wild sea ; for tho the storm was abated considerably , yet the sea went dreadful high upon the shore , and might well be call d , den mild zee , as the dutch call the sea in a storm 最后，海浪把我冲上了岸，等浪势使尽而退时，把我留在半干的岸上。虽然海水已把我灌得半死，但我头脑尚清醒，见到自己已靠近陆地，就立即爬起来拼命向陆上奔去，以免第二个浪头打来时再把我卷入大海。可是，我立即发现，这种情境已无法逃脱，只见身后高山似的海浪汹涌而至，我根本无法抗拒，也无力抗拒。
The high voltage windings is made by sectional aluminium foil with glass fiber and resin casting , the voltage between turns is very low , the partial discharge is very low , there is no cracking , since the expansion factor of conductor and insulation material is similar , it also has the advantages of no corrosion , no pollution , low losses , low noise level , anti - vibration , fire protection , maintenance free , long operating life and high reliability 低压绕组为铜箔绕制，半干nomex纸做层间和外层绝缘，经干燥与铜箔固化为一体，散热好强度高。高压绕组为分段铝箔绕制，玻璃丝网架环氧树脂浇注，层间电压低，局部放电小，导体和绝缘体膨胀系数相似，不裂寿命长无腐蚀无污染损耗小噪音低抗震阻燃免维护运行安全可靠。
Back covered porous brick has been developed in the late period of 1990 ' s , and is produced by semi - dry - pressing method . it has such many advantages as high production efficiency , energy saving , high density , beautiful appearance , high strength , easy bricklaying , and can save 1 / 3 masonry mortar compared with solid brick 盲孔多孔砖是20世纪90年代后期研制成功的、用半干压法压制成型的封底多孔砖，它生产效率高，节约能耗，产品致密，外形好，强度高，易砌筑，用于砌体工程时，可节约1 3砂浆。
It presents three types of friction between parts of the engine ( complete fluid friction , edge friction and half dry friction , dry friction ) and renault equation , and sets forth the friction and the lubrication of cam - driven parts , crankshaft , piston and piston ring . also it shows the forecast technique of the friction losing in designing engine 介绍了发动机零部件间的三种摩擦状态(完全液体摩擦、边界摩擦和半干摩擦及干摩擦)和雷诺方程，阐述了凸轮?从动件、曲轴、活塞及活塞环的摩擦和润滑，并给出了发动机设计时摩擦损失的预测方法。
