摘要
2013年4月代县地震台观测的茶房口流动水准、眉音口流动水准、大石口流动水准、小磨流动水准测线测量结果较2013年2月变化大。经异常落实,认为代县地震台2013年4月4条测线测量结果变化较大与本期更换新标尺有关,且高差大的测线累积差变化较大,高差小的测线累积差变化较小。
In April 2013, the change value of four mobile leveling lines is larger change than prior pe- riod (February, 2013), including Chafangkou, Meiyinkou, Dashikou and Xiaomo. Through anomaly verification,it was thought that the larger change (April, 2013) of four mobile lev- eling lines is possibly due to replacing the scale in the period. And, the bigger the elevation difference is, the bigger the cumulative difference is; and vice versa.
