物质坐标 meaning in Chinese

material coordinates
substantial coordinates

In this article , several existing main compensation methods for the term of dynamic stiffening are reviewed ; describing method of material coordinate is introduced on the basis of the principle theorem of mechanics of continuum ; and the dynamic equation of flexible body is derived from nonlinear green strain tensor and kichhoff stress tensor , which are based on initial configuration
本文评述了现有的几种主要的动力刚化项补偿方法，根据连续介质力学的基本原理，引入物质坐标的描述方法，采用基于初始位形的非线性green应变张量和kichhoff应力张量推导柔性体的动力学方程。
