【Abstract】 Using MATLAB,the digital teaching software of Maxwell’s speed distribution function is compiled.The software can deal with Maxwell speed distribution function in digital.That is to say,it can draw the Maxwell’s speed distribution function curve,show the most probable speed,average speed,root mean square speed,calculate the probability of molecular speed distributing in a interval,compare two gases’ speed distribution and dynamically simulate the speed distribution varying with the change of temperature or the molecular weight.Using the software,the three kind of speed is studied,of which belongs to 10 kinds of chemical gases in common.The work can make a contribution to Maxwell’s speed distribution function in teaching and researching.更多还原
