D6h^4结构空间群的IR矩阵和IR基的计算

The Calculation of D 4 6h Structure Space Groups IR Matrics and IR Gelfand Basis

在晶体空间群的Ｃ—Ｇ系数计算中，空间群的ＩＲ矩阵的计算具有极其重要的作用．本文利用本征函数法〔１〕，计算了Ｄ４６ｈ结构空间群的ＩＲ矩阵．同时给出ＩＲ基的计算。

In the calculation of crystal space groups C G coefficients, the calculation of IR matrics play an important role. In this article, the authors calculate IR matrics of D 4 6h structure space group by Eigenfunction method, and do same to the IR Gelfand basis, ralative phase factor among the IR Gelfand basis. KEY WRODS Space group, wave vector group, representation group, irreducible representation, irreducible basis, eigenfunction method.Nonquantum Mechanics Effect of Neutrino Oscillation Experiment of Ling Base Lone in Matter$$$$ SUN Mengtao LIU Kuiyong MA Fengcai Department of Physics, Liaoning University, Shenyang 110036 Abstract Nonquantum effect of neutrino oscillation experiment of long base line in matter was studied, and its effects on the allowed region of neutrino oscillation possibility and mixture parameters (sin 22θ,Δ) was calculated.
