建立了矩阵函数单重积分的格点漂移技术，并阐述了其特殊的数学意义；把格点漂移技术应用于分立基量子系统中的一般转动算符矩阵的格点方法计算中，并将其结果应用于计算二维叠加态在一般转动算符作用下的几率分布演变比。
We have set up the lattice drift technic of the single integral of matrix function and expounded in detail its special mathematical meaning; and appied this technic in the lattice calculation of the general rotation operator matrix for the quantum system in discrete bases, and using the results obtained, we calculate the evolution ratio of the probabitity distribution for the two-dimensional superposition states under the action of a general rotation operator.
