为了探讨在不同径向角下动量比和湍流度对圆柱形气膜孔流动和换热的影响规律，采用数值模拟方法，研究了涡轮叶片的冷却效率。

The cooling effectiveness of cylindrical gas-film cooling holes was numerically investigated, which was determined at different radial angles, momentum ratio and turbulent intensity.

一个节点，2减去1等于1,因为l等于1,我们有一个角向节点，那剩下径向节点有多少个呢？

Yup, so one total node, 2 minus 1 is 1, and that means since l is equal to 1, we have one angular nodes, and that leaves us with how many radial nodes?

单列角接触球轴承可承受径向，轴向或复合负荷，不过，任何轴向负载必须在一个方向。

Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.

so, remember we can break up the total wave function into the radial part and the angular part.

记住我们可以把整体波函数,分解成径向部分和角向部分。

So you can see there's this radial part here, and you have the angular part, you can combine the two parts to get the total wave function.

你们可以看到，这是径向部分，这是角向部分，把这两部分结合到一起,就是总的波函数。
