A general method to quantify the inclusion dispersion of mixture microstructures has been developed. The dispersion quantity, D, is defined as the probability of inclusion particle free-path spacing falling into a certain range of the mean spacing mu, according to the particle spacing data frequency distribution. Two quantities, D(0.1) and D(0.2), are proposed, which are the probabilities of the particle free-path spacing falling into the ranges of mu+/- 0.1 mu and mu+/- 0.2 mu, respectively. Both normal and lognormal distributions are discussed, and in both cases, the quantities D(0.1) and D(0.2) are specified as monotonous increasing functions of mu/sigma, where mu and sigma; are the mean particle free-path spacing and standard deviation, respectively. Examples of composite are presented to quantify the dispersion of foreign reinforcements based on the proposed method.
已经开发出一种量化混合微结构中夹杂物分散度的通用方法。根据颗粒间距数据频率分布，分散量D定义为夹杂物颗粒自由程间距落入平均间距μ的特定范围内的概率。提出了两个量，D(0.1)和D(0.2)，分别是颗粒自由程间距落入μ±0.1μ和μ±0.2μ范围内的概率。讨论了正态分布和对数正态分布，在这两种情况下，量D(0.1)和D(0.2)都被指定为μ/σ的单调递增函数，其中μ和σ分别是平均颗粒自由程间距和标准差。给出了复合材料的例子，以基于所提出的方法量化外来增强体的分散度。
