摘要
提出提高统计线性化精度的新方法,同时研究高阶矩传播法的计算方法,并以此方法做为衡量计算精度的标准,计算结果表明,提出的修正方法改善了计算精度。
A new method of improving the accuracy of statistical linearization is developed. Meanwhile, a higher moment propagation method is introduced and used as the standard of testing the calculation accuracy. Numerical computations indicate that the modifying method developed here can improve the accuracy and is easy to use.
