Radioisotopic tracer technology measuring waterentry profile has been used in oil fields for a long time.
放射性同位素示踪法测吸水剖面工艺在油田已应用很久了。

As underwater depth increases, metacenter height increases, but waterentry Angle decreases, so the platforms allowable swing angles also decrease.
随着吃水深度的增加，平台的稳心高变大，但平台入水角减小，所以平台的容许摆动幅度降低。

Experiments and analysis results show that lowering and raising stability mainly rests with the platform underwater depth, structural characteristics, waterentry Angle, etc.
