摘要
本文用了一个均匀密度的三轴椭球晕,对沉浸在其中的非轴对称盘星系受到的扭矩作了一级近似计算。这个扭矩虽然量级很小,但对盘星系的角动量演化是一个长期的效应。
The torque on a disk galaxy embedded in a Uniform triaxial halo has been calculated in the first order. The absolute value is small, but the long term influence to the evolution of the dynamics of the disk galaxy is not negligeable.
