All holes, slots, edges and corners should be free of loose burrs and slivers. The allowableheight of a burr cannot exceed five percent (5%) of the material thickness.
所有孔，缝，边和角必须没有毛刺和锐边。允许的毛刺的高度不能超过材料厚度的5%。

As underwater depth increases, metacenter height increases, but water entry 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。

It is also found that there exists a maximum isolated structure period at which the height width ratio is zero or the displacement of the rubber bearing exceeds the allowable value.
