重心轴 meaning in English

axis of gravity
gravity axis

Based on the same principle of floating stability calculation of rectangle caisson , the moment of inertia of gravity axis of the fan shape is transformed through coordinate transformation formula , and the general formula and calculation method of floating stability for c limier caisson with partition ails are obtained
摘要引用矩形沉箱浮游稳定计算的相同原理，把扇形重心轴的惯性矩通过转轴公式的转换，再经数学证明，得到带箱格圆形沉箱浮游稳定计算的通用公式和计算方法。
