| 摘 要： | 上限对数正态分布（LN分布）和Rosin-Rammler分布（R-R分布）经常同时用于拟合同一种雾状水幕水滴粒径分布。该文研究这2种分布函数之间能否等价、能否近似相互转换以及转换的条件,为雾状水幕粒度试验数据分析和相关数值计算中的分布函数选择、使用和转换的进一步研究提供参考。在推导上限LN分布函数的累积体积百分比公式和...

| Abstract: | Upper limit lognormal(LN) distribution and Rosin-Rammler(R-R) distribution functions are often used to simultaneously describe the droplet diameter distribution of the same water spray.This paper investigates the equivalence,approximation and conversion conditions of the two functions for the choice and application of these functions and the data transformation between the two functions in the data analysis and calculation.The Euclidean space distance was used to evaluate the optimum approximation of the tw... |
