摘　　要：通过构造以夹杂纵横比为交量的函数，导出了计算非完美界面复合材料有效模量中，将任意夹杂形状转化为球形夹杂计算的普遍公式。进而得到了纤维夹杂和圆盘夹杂非完美界面复合材料有效模量4个下限之间的相关公式。By construction of functions which use the aspect ratio of the inclusion as variable, the universally valid formula that cantransform from arbitrary inclusion shape into the spherical inclusion to calculate the bounds of effective monduli for comPOsite with imperfect interface is deriated. Futhermore, the related expression of the four lower bounds of stiffness for the composite with the fullrange of inclusion shapes from thin disk-like inclusions to slender needle-like ones is acquired.
