摘　　要：本文研究脉冲星的周期变化与地壳运动的关系,指出:(1)由地震引起的板块运动和板内运动会影响观测到的脉冲星的脉冲周期的变率,特别是一些周期变率较小的脉冲星,这种影响将产生显著的观测效应;(2)分析现代脉冲星的观测资料,有助于研究板块结构,板块运动和地震预报。This paper discusses the relation between the rate of periodic change of a pulsar and the motion of the earth's crust. The results are as follows: (1) The plate motion from an earthquake may affect the observed numerical values of the rate of periodic change, and the effect is especially obvious for the pulsars with small rates of periodic change. (2) We may research into the plate structure, plate motion and earthquake forecast by analysing observed data of modern pulsars.
