In general, the force will have both a radial and a circumferentialcomponent.
通常，这个力有一个径向分量和一个周向分量。

Additionally, the larger the circumferential velocity component of hub leakage flow, the greater the deleterious effect of hub leakage upon the rotor flow.
另外，叶根泄漏流的周向速度分量越大，泄漏流对转子流场的不利影响也越大。

Thick wall pipes are the core component of so called "four pipe" system for thermal power. It is important to apply circumferential guided wave technique to nondestructive testing of thick wall pipes.
