中文摘要：

介绍了InSAR及其差分技术的基本原理，并以发生在2004年7月12日西藏日喀则地区仲巴县与阿里地区之间（北纬30．5°，东经83．4°）的里氏6．7级（中国台网测定）仲巴地震为例，采用已知DEM的二路差分法获取了仲巴地震的同震形变场。采用Okada弹性半空间位错模型反演了该地震的震源参数，得到了震源机制解。结果表明，仲巴地震为以倾滑为主的右旋正断层型地震，断层面走向近乎南北方向。

英文摘要：

InSAR and differential interferometric synthetic aperture radar （D-InSAR） are generally introduced; Zhongba earthquake which occurred in July 12, 2004 between Tibet Xigaze area Zhongba county and the Ngari area （northern latitude 30. 5 , east longitude 83.4°） with the Lishi magnitude 6. 7 is selected as an example to obtain the coseismic deformation field with the two-pass differential interferometric processing method. The Okada elastic half space dislocation model is used to inverse inversion this earthquake＇s center of origin parameter, to obtain the focal mechanism solution.
