Assuming that the friction angle on different slip planes varied with the angle between the slip plane and bedding plane, an anisotropic strength criterion was established based on the concept of SMP. The formulation for cross-anisotropic granular materials was then derived.

基于SMP准则，假定不同平面上的摩擦角随该平面与沉积面之间的夹角变化，提出了一般应力条件下各向异性粒状材料的强度准则，称为ASMP准则，给出了该强度准则在横观各向同性条件下的表达式。

Generally, the Fresenl lens is used for collimation and its structure is planeconvex, but the analysis and comparison of the biconvex and the plane-convex Fresenl lenses with P-W method show that the biconvex Fresenl lens is better because of its specific imaging requirement. The two kinds of the Fresenl lenses were modeled in ZEMAX to validate the conclusion.

从应用角度看，菲涅尔透镜设计属于准直系统，一般采用平面结构，但由于其成像要求的特殊性，通过运用P-W方法进行分析和比较，结果表明：曲面的设计较之于平面更具优势，并在ZEMAX中分别对2种菲涅尔透镜进行建模，验证了结果的正确性。
