# 两种坐标系下速度(率)、能量、动量的分布Velocity, Energy and Momentum’s Distribution Based on Two Coordinate System

Abstract: In this paper, the distribution of velocity in Cartesian coordinates and spherical coordinates de-duces on the basis of the distribution of energy and momentum, and calculates the most probable speed in both coordinates and the most probable energy, average speed, average energy and av-erage momentum and other related physical quantities. Through the analysis results, we found that: in the both coordinates, the calculation result was consistent with scalar, vector calculation results were different. This paper also studied the scope of Maxwell distribution and the reason why the most probable energy Maxwell energy distribution corresponding speed and the most probable speed of Maxwell velocity distribution values were not equal.
