metacentric radius

This paper points out that determine factor is the relative place of the centre ofgravity and the centre of stable inclination,instead the centre of gravity and buoyancy.

本文指出,决定浮体平衡与否的是重心与定倾中心的相对位置,而不是重心与浮心的相对位置,在重心低于或等于定倾中心时,浮体就处于稳定平衡。

By taking the central island radius as the key parameter,its relationship with the traffic operation of the signalized roundabout was discussed.

文中将中心岛半径作为关键参数,研究其与信号控制环形交叉口交通运行的关联性。
