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.
