摘要： 采用线性回归和优选法相结合的方法较好地解决了形如函数ｙ＝ａ［１－ｅｘｐ（－ｂｘ）］的曲线拟合问题。通过对中国光学太阳反射器卫星搭载数据的拟合分析，得出了光学太阳反射器的光学性能的空间衰变的经验表达式，并对光学太阳反射器的长期空间稳定性进行了预测。

Abstract: he curve fit of the function y=a[1-exp (-bx)] has been resolved by combining linear regression and optimum seeking method. The empirical expression for space o ptical property degrada non of Optical Solar Reflector has been obtained from 'the fitting analysis of satellite flight test data of the Optical Solar Reflector developed by China. The longterm space stability of Optical Solar Reflectol has been predicted.
