When light transmits through aeolotropic crystal,as far as extraordinary light is concerned,there is a smaller included angle between the ray and the wave normal in general,which is usually called walk-off angle.

Aim To study the effects of walk-off angle on the coefficients of reflection and transmission.

Considering the effect of walk-off angle, the accurate calculation of effective nonlinear optical coefficient of uniaxial crystal is presented, a example of calculation of BBO is given.

Based on the analysis of the masterpieces of three leading figures in Chinese American literature,this thesis will take a new multidisciplinary approach to explore the special quality of Chinese American writers and their works----"hybridity" by means of the combination of postcolonial translation theory,the diasporic perspective in cultural study and narratology.

Experiment research on angular spread characteristics in suburb environment

Through physics modeling,the spatial spread characteristic in the mutipath fastfading chnnel is introduced,and using the computer imitated results of typical parameter values in the typical environment,some conclusions about spatialangular spread characteristic are gained,and the shortages of the performance research about mobile channel are made up.

By isolating the central DOA and angular spread into decoupled parts,2-D joint searching can be simplified to sequential 1-D searching,which reduces computational complexity.
