The results show that in line vibration can not bring serious danger to submarine pipeline system in most cases, while crossflowvibration must be eliminated.
There are mainly two excitation mechanisms in the vibration of the thermo-well at the main pipe of reactor coolant loop under crossflow: turbulence and vortex shedding.
反应堆冷却剂回路温度计套管在流体流动冲刷下的振动主要有两种激励机理：湍流和旋涡脱落。

The main influence parameters on vibration were briefly explained. The mechanism of induced vibration in two-phase cross-flow and the necessary formulae were emphatically expounded.
