| 摘 要： | 利用Venedikov调和分析方法，计算了南天山西段8套数字化形变观测资料的潮汐参数：O1波和M2波的潮汐因子、中误差、观测振幅以及M2波的相位滞后与中误差，分析并评价了资料的精度和稳定性，为今后的资料使用和异常判定提供科学的参考依据。结果分析表明：（1）阿合奇、哈拉峻和乌什3个台地倾斜资料、乌什洞体应变仪资料和乌什重力仪资料潮汐分析结果较好，中误差小，精度均达到了中国地震局形变I类台的标准；（2）马场台井下倾斜仪EW向γM2偏小，受格值或者仪器常数影响较大；（3）喀什栏杆乡和乌恰井下倾斜仪两分向的定位存在较大偏差。

| Abstract: | Using Venedikov harmonic method, this paper not only calculated tidal factor, mean square error,observation amplitude and phase lag of O1 and M2 wave from eight sets of digital deformation observation data, but also provide scientific reference for anomaly judgment through evaluating precision and continuity of observation data. The result shows ： （ 1 ） analysis result of ground tilt in Aheqi ,Halajun and Wushi, cave strain and gravimeter in Wushi reached I type deformation standard of China Earthquake Administration and with low mean square error; （2） EW direction in Machang was influenced by lattice-valued and instrument constant;（3 ）location deviation existed between two directions of tiltmeter in Kashi and Wuqia. |
