摘　　要：介绍了SS YD型断层观测伸缩仪的系统组成及其基本原理。该系统实行现场自动采集和自动储存并由“数据交换器”进行数据调用和回放 ,具备交直流电源自动转换及有效的避雷装置 ,实现了无人值守。仪器所得观测数据稳定 ,并记录到清晰的应变固体潮汐与台湾“9.2 1”大地震 0 .5This paper describes the basic principle and composition of the extensometer of SS YD model which is used for fault deformation observation. Data acquisition and storage on the spot are done and conveyed to computer in office by Data Exchange Set at any time, so an unattended station is come true.\;The records are stable and show that the earth strain tide and a coseismic step with earthquake on Sep.21,1999 in Taiwan had been recorded
