| 摘 要： | 利用模拟退火算法识别大气压强公式中的参数,得到更精确的大气压强计算公式.该方法首先把参数识别问题转化为优化问题,然后运用模拟退火算法求出由多态方程推导所得大气压强公式中的大气比热比γ,从而得到更精确的大气压强公式.通过数值模拟,将本文得到的公式与其它文献给出的大气压强公式进行比较,结果表明用模拟退火算法所确定的大气压强公式精度更高.

| Abstract: | In this paper,a new approach based on simulated annealing algorithm for the precise inversing identification is proposed to attain the precise formula of the atmospheric pressure. It transforms the parameter inversing identification problem into the solution of optimization problem. The atmospheric specific heat ratio in the atmospheric pressure formula, which is derived from the polymorphic equation, is calculated exactly by using simulated annealing algorithm. Thus we attain a precise formula of the atmospheric pressure. By numerical simulated and comparing with the results given by the documents, it shows that the calculated value by the SA match the actual pressure value much better. |
