摘要 利用MATLAB软件分别得到不同地区库存单基发射药贮存寿命与温湿度关系的拟合曲线,发现拟合曲线符合二次模型。利用环境特征相对典型地区的温湿度数据,建立了纯二次回归模型,得到贮存寿命与温湿度的回归方程。回归方程的剩余标准差和残差极小,表明拟合效果非常好,能够较准确预测不同温湿度条件下单基发射药的安全贮存寿命。 The influmence of the temperature and humidity should be considered for forecasting the storage life of propellants. The relation curves of storage life of propellant in various areas to the temperature and humidity Were obtained by using MATLAB software, discovering that their fitting curves accord with quadratic form. The regress model of pure quadratic form was established according to the temperature and humidity data where environment character was relatively representative. The regress equation with small rmse and residuals was obtained, and the regress model had great fitting effect, and the results obtained could be used to exactly predict the safe storage life of singlebase propellant under different temperature and humidity.
