坐标系的物理基础及其空间性质
PHYSICAL BASIS AND SPATIAL NATURES OF A COORDINATE SYSTEM
摘要
Abstract
By outlining the space-time theory in Newtonian mechanics and Einstein's Relativity, it is pointed out that the crustal movement is a kind of macro-phenomenon of low speed. Thus adopting the Newtonian mechanics to describe position of a crustal particle as well as how it is changed by external forces along with the time are absolutely feasible, and a reference frame without any motion of acceleration is pretty necessary for depicting a crustal movement in a right way by using the Newton Laws. That is, a reference frame in accordance with the Newton inertia Law is one of the physical foundation of coordinate system for the purpose of crustal motion analysis. Considering that different coordinates have their own metric tensors in the respective virtual space on reference surface, they also have different sets of intrinsic geometric properties . Finally, a discussion on the spatial natures of the Cartesian,plane and spherical coordinate systems is made.关键词
