摘要
在已给出的离散型解舒丝长分布的基础上 ,考虑在茧丝上任意部位都可能发生落绪 ,且落绪率在茧丝上呈连续曲线形分布的条件下的解舒丝长分布。给出解舒丝长一类具有寿命分布形式的连续型随机变量的概率密度函数。并由其分布求出解舒丝长平均值及方差。
In this paper, based on discrete distribution of non-broken filament length of cocoon, we derived its continuous distribution, that is a distribution of lifetime, and the mean value and variance, with the hypotheses that the ratio of dropping end has continuorsly distributed form on cocoon filament. Basis on the condition that ratio of dropping end is distributed on cocoon filament with a parabola-form, we discussed on the relation between the distributed form and the parameters of ratio of dropping end. The theoretical results have been tested and verified by computer simuration.
