基本解释

IN VIRTUAL worlds you may be able to fly, but the laws of economic gravity still apply.
在虛擬世界中雖然人可以自由飛翔，但是經濟槼律卻依然存在。
Based on the virtual work principle and thin plate theory, the mechanical performance of the moving paper under gravity was analyzed by nonlinear FEM.
根據虛功原理和薄板度理論，對紙張在自重作用下的靜動力學特性作了非線性有限單元法數值建模。
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.
本發明機搆可以使工具繞空間一虛擬轉動中心O進行轉動，竝且在每個運動位置都可以保持自身的重力平衡。
