基本解释

IN VIRTUAL worlds you may be able to fly, but the laws of economic gravity still apply.
在虚拟世界中虽然人可以自由飞翔，但是经济规律却依然存在。
Based on the virtual work principle and thin plate theory, the mechanical performance of the moving paper under gravity was analyzed by nonlinear FEM.
根据虚功原理和薄板度理论，对纸张在自重作用下的静动力学特性作了非线性有限单元法数值建模。
Through the mechanism of the invention, the tool can rotate around a virtual rotation center (O) in the space, and can keep the self gravity balance in each movement position.
本发明机构可以使工具绕空间一虚拟转动中心O进行转动，并且在每个运动位置都可以保持自身的重力平衡。
