摘要距离和坐标系是物理学中的基本概念,本论文从距离测量入手,探究了距离是信号传播过程的体现的这一本质含义,并根据光子的量子性和受引力场作用等性质,尝试基于实物之间的光子自由传播过程建立空间球坐标系,指出了物理学坐标系与数学坐标系的本质区别。通过引入空间变尺度因子R(t)概念,计算了平直时空直角坐标系与变尺度因子空间球坐标系的变换以及变尺度因子空间球坐标系的对角化,得出变尺度因子时空中光程差的表达式。此外,本文还简要介绍了几种不同参数的R(t)所对应的宇宙模型,并通过河外星系红移的例子说明了变尺度因子空间球坐标系在解释宇宙红移现象的有效应用。5940

Title Photon free path space spherical coordinates model and its application
Abstract
Distance and coordinate system are basic concepts in physics, this paper started from distant measurement, researched the nature meaning of distance that distance is the embodiment of signal propagation, and according to quantum character of photon and by gravity field role, have tried that based on photon free path establish space spherical coordinate system,pointed out that the nature difference of physic coordinate system and mathematic coordinate system. By introduced variable space scale factor R(t), calculation the transform between straight space-time rectangular coordinate system and variable scale factor space spherical coordinate system, obtained the expression of optical path difference in the variable scaling factor space-time. In addition, this article also outlines several different parameters of r(t) model of the universe, through introduced the redshift of extragalactic system illustrated the effective application of variable scale factor space spherical coordinate system in explaining cosmological redshift phenomenon.
