摘要
本文应用等离子体物理学动力论中发展起来的方法来研究均匀无碰撞简并粒子自引力系统中的扰动，导出在这种系统中小振荡的色散关系，并给出计算阻尼时间的算式．
Methods developed in the kinetics for plasma physics are used for the investigation of the perturbation in homogeneous collisionless self-gravitation systems of degenerate particles. The dispersion relation of small oscilations in memtioned systems is derived,and the formulae are given for calculation of the damping time and the collapse time.
