Some calculation was did to study the light scattering caused by pores and grain boundary phases in transparent ceramics with cubic structure,such as Nd-,Yb-,Tm-dopped YAG,Y2O3 and Sc2O3.Mie scattering theory and Rayleigh scattering theory were used to calculate the scattering cross-section,and its relationship with the scale,shape,distribution and density of pores or grain boundary phases was discussed.Lambert-Beer Equation was used to simulate the in-line transmittance with the affect of scattering by pores or grain boundary phases.All the calculations was done with Matlab programs.

摘要：随着社会经济的进一步发展，我国新课标改革越来越注重培养学生全面发展的素质，提高学生的基本技能。在进一步挖掘学生潜在能力的同时，要注重对学生创新能力、尝试能力、分析能力的培养，充分发挥学生在学习中的主导地位。初中思想政治课大多与理论知识为主，平时课程少，使初中思想政治教学效果低下，影响了学生德、智、体、美综合素质的全面发展。因此，本文主要探讨了尝试教学法在初中思想政治教学中的相关应用，并根据当
