旋转矩形静矩与惯性矩关系系数研究

Research on the Relational Coefficient of Static Moment and Moment of Inertia of a Rotating Rectangular

液体的稳定度取决于一个无量纲系数,定义为静矩与惯性矩关系系数,从理论上研究该系数所具有的性质对解决液体体系的平衡问题具有重要意义。分析了矩形绕端点在其所在平面内旋转时,静矩与惯性矩关系系数p'y和p'x的性质。

The stability of liquid system is determined by a non - dimensional coefficient which is called relational coefficient between static moment and moment of inertia. Research on the properties of the relational coefficient in theory for the balance of the liquid system is of great importance. When the end of the rectangle is rotated in the plane, analysing the nature of the relational coefficient py ,Px
