理想气体分子速率分布定律的证明

A PROOF ON THE DISTRIBUTION LAW OF THE IDEAL GAS MOLECULE VELOCITY

单个气体分子的速率是偶然的，但大量气体分子的速率分布是有规律的．速律在Ｖ到Ｖ＋ΔＶ之间的分子数ΔＮ占总数Ｎ的百分率ΔＮ／Ｎ是确定的．

The velocity of single gas molecule is accidental, But it is regular to the velocity distributies of lots of gas molecules. The percent ΔN/N(ΔN: the number of molecules whose velocity is between V and V+ΔV, N: total number of molecules)is definite, the simple proof of the conclusion is given by probability statistics method in the parper.
