At the same time, this thesis focuses on the theoretical research on the LBGK method and discusses the inner relation between the LBGK and the N-S equations.The relationship among the selection of velocity group , the forms of equilibrium distribution functions,and the macroscopic N-S equations is clearly revealed.LBGK method has many advantages, such as easy dealing with the complex boundary conditions and high amenability to parallel computing.

本文系统地总结了各种LBGK模型，特别是对LBGK模拟二相流和多相流模型进行了认真地研究；同时从新的角度对LBGK进行了理论研究，用全新的方法探讨了LBGK和N-S方程的本质联系，清晰地揭示了速度族的选择、平衡态分布函数的形式和宏观NS方程三者之间的关系。

In the geometry space, azimuthal anisotropy and coplanarity of sec- ondaries in the families are reproduced by normal model. However in the momentum space, the anisotropy of showers in the data is less than the both perditions of our two Monte-Carlo models.

共面结构事例在几何空间分布的各向异性性质可以用现有理论完全解释，但是实验族在横动量空间的各向异性程度明显小于两个不同模型的预言，其原因还有待进一步研究。

The transport and current-voltage properties of submicron GaAs MESFET device are calculated firstly based on the nonparabolic effective mass energy band model and Monte Carlo method which includes all major scattering mechanisms. The electron drift velocity, electric field and the non-homogeneity of mobility distribution in device are obtained. The influences of different gate lengths to electron drift velocity and drain current are analyzed.
