摘要
利用有关文献提供的大气在 1～ 11km对流层的大气压强实测数据 ,运用遗传算法反演精确计算出由多态方程推导大气压强公式中的大气比热比γ ,从而给出计算大气压强的精确公式 ,其计算值与实测值非常吻合 ,并与文献给出的大气压强公式进行了比较 ,结果表明 ,用遗传算法所确定的大气压强精确公式更准确 。
Using the actual measuring datum of the atmospheric pressure at 1～11km troposphere of atmosphere provided by some documents,The atmospheric specific heat ratio in the atmospheric pressure formula,which is derivated from the polymorphic equation,is calculated exactly by using the inversion of genetic alrgoithms so the precise formula of the atmospheric pressure is given out and the calculating number and the actual pressure one are very identical.Comparing with the atmospheric pressure formula given by the documents the result shows that the precise formula of the atmospheric pressure definited by the genetic algorthms is more accurate.It proves that the genetic algorithms has a very high applicational value in the inversing problems.
