摘要
本文讨论了自１９９０年以来，使用拉科斯特时重力仪在辽宁西部地区进行重力复测所取得的成果资料，并着重分析了１９９４年１０月２２日朝阳４．９级地震前后重力异常变化情况。结果表明，地震发生与重力变化有着密切的关系。
The data of gravity reiteration in western Liaoning area,which have been obtained by means of Lacoste gravity meter since l990,are discussed in this paper.Anomalousgravity variation before and after Chaoyang earthquake with M_L=4.9 on Oct.22,1994,kspecifically analyzed.The result shows that there exists close relation between occurrence ofthe earthquake and gravity variation。
