大震

本文利用永胜地震台FSQ型浮子水管倾斜仪原始记录图形，分析澜沧、耿马大震前后地形变的特征。

The variation of crustal deformation before and after Lancang-gengma earthquakes has been analysed by means of original records of FSQ floating water-tube tiltmeter installed at Yongsheng station .

本文从楚雄地震台FSQ型水管仪的原始资料出发，探讨了澜沧、耿马大震前地形变前兆信息量的问题，指出了孕震体的变化过程。

Based on the original data recorded by type FSQ float water piper from Chuxiong station , the authors made an approach on quantity of precursory informations of deformation and put out the process of seismogenic varying body before the great Lancang Gengma shock .
