针对此分布不匹配的问题，本研究首先提出使用截尾分布机率密度函数(truncated probability distribution function)的概念来近似。

The offered simples can not completely accorder with the assessment model, so the error was regarded as the object function, and the optimum probability assessment model was presented. In order to optimize the model's distribution parameter, the improved genetic algorithm was adopted.

对原始数据在评估模型中产生的误差作为目标函数，建立概率评估优化模型并采用改进遗传算法对分布参数进行优化计算。

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.

认为颗粒增强金属基复合材料的界面脱黏受控于颗粒所受的拉应力，引入Weibull分布函数描述颗粒脱黏概率，且受单向拉伸载荷作用时，仅在沿受力方向的上下两侧发生部分界面脱黏，从而将部分脱黏的各向同性颗粒由一完好的横观各向同性颗粒来等效，建立了部分脱黏模型。
