本文对文献〔1〕导出的PWM法计算P-Ⅲ型分布参数公式作了改进,使PWM法能够应用于实际。文中还提出了一种简化的PWM法,经统计试验及实际算例表明,此法比现有方法更简单,又能满足精度要求。
In this paper, the literature [1] derived PWM method to calculate the P-Ⅲ type distribution parameter formula has been improved so that the PWM method can be applied to the actual. In this paper, a simplified PWM method is also proposed. The statistical experiments and practical examples show that this method is simpler than the existing methods and can meet the accuracy requirements.
