实验过程中使用可视化方法观察确定过冷沸腾净蒸汽产生点。

The point of net vapor generation was determined by visual observation.

本文取摇摆为海洋影响条件，研究摇摆对竖直管自然循环过冷沸腾气泡脱离点的影响。

The rolling motion is chosen as the ocean condition in this experimental study, we study on Natural Circulation subcooling vapor bubble departure in vertical channel.
