The CFD method was applied to calculate and simulate the form and action process of the cavitation at the representative character of the cavitation erosion on the surface of the hydraulic turbines.Some argumentation was presented that micro jet impacted the wall with a certain degree when bubble collapsed with the result that the maximal strain of the wall annularly distributed the local of the boundary touching the micro jet.Cavitation was gradual to develop regionally at the mode of chain reaction and di...

针对水轮机叶片表面气蚀的典型特征，利用CFD方法进行仿真计算，模拟气蚀形成和作用过程；根据模拟计算结果提出了新观点：空泡溃灭发生微射流以一定的倾角冲击壁面，壁面材料产生的最大应变在流束边界局部区域，呈环状分布；空泡气蚀在局部区域是渐进的，以"连锁反应"形式扩展，具有一定过流环境的分布特征；典型的冲蚀缺陷形貌是空泡气蚀在不同阶段的产物。

What is called that the annulus of the inner cylinder executing a planetary motion is: the inner cylinder which can form the annulus is not only rotating by the axis of itself, but also rotating by the axis of the outer cylinder in the annulus.

所谓内管做行星运动的环空是指：构成环空的内管不仅绕其自身轴线自转，而且还同时绕环空外管的轴线公转。

Right shifting an unsigned quantity always fits the vacated bits with zero. Right shifting a signed quantity will fill with bit signs ("arithmetic shift") on some machines and with 0-bits ("logical shift") on others.

在对unsigned类型的无符号值进行右移位时，左边空出的部分将用0填补；当对signed类型的带符号值进行右移时，某些机器将对左边空出的部分用符号位填补，而另一些机器则对左边空出的部分用0填补。

Empty pallet stored in pallet magazine is automatically conveyed underneath the filling spout; After the bag is hung and bag mouth fastened around the filling spout manually, the bag is prepared for incoming material; Materials in the feed hopper are discharged into empty bags, then weighed by loaded pallet, weigher (standard weight 1000kg); After weighing is completed, the bag is automatically released from bag clamper and hanging apparatus in loaded pallet scale to pallet conveyors.

存贮在托盘仓库中的空托盘自动输送到装袋位置。人工把空包装袋套入装袋机下料口后，夹袋器夹住袋口，做好接受来料的准备。给料箱将物料送入空包装袋中，并利用垛盘电子称称重（标准重量1000公斤）。称重完毕，夹带器及垛盘电子称上的挂袋装置将料袋释放到托盘上。

The litter baskets were empty and the ground was covered with pieces of paper, cigarette ends,old tyres,empty bottles and rusty tins.

废物筐是空的，而满地都是纸片，废物筐是空的，而满地都是纸片，烟头，旧轮胎，空瓶子和生锈的空罐头盒。
