【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。更多还原

【Abstract】 In April 2013,the change value of four mobile leveling lines is larger change than prior period(February,2013),including Chafangkou,Meiyinkou,Dashikou and Xiaomo.Through anomaly verification,it was thought that the larger change(April,2013) of four mobile leveling 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.更多还原
