摘　　要：针对2015年辽宁省辽西测区第二期流动重力测量朝阳测点的测值突变,变化近-50微伽,参考相邻测期测量资料的分析以及测点周边环境变化图。分析与现场检验结果表明:测值变化可能系质量缺失所引起。Based on the mutation of the early sun measuring point of the second phase flow gravity measurement in Liaoxi District of Liaoning Province in 2015,it changed nearly 50 microga. Referenced to the analysis of adjacent measurement data and the change of environment around the measurement point, the results were concluded that the change of the measured value may be caused by the lack of quality.
