用道耳顿分压定律分析大气压强公式的误差

An Analysis of the Error of the Formula of Atmospheric Intensity of Pressure by Using the Dalton Partial Pressure Law

对大气压强公式产生误差的原因进行了分析，指出，由于大气中分子质量不同引起的计算误差是产生误差的主要原因，由此提出公式修正，并给出大气压强公式所适应的范围。

In this paper, the reason of the error which is produced by the formula of atmospheric intensity of pressure is analyzed and that the calculation error brought by the different molecule mass in atmosphere is the main reason of the error is pointed out. And then the modifying of the formula is presented and the range adapted by the formula of atmospheric intensity of pressure is given.
