摘　　要：利用潮汐因子内精度、相对标定自检内精度、面应变相关系数等指标,综合对比分析天山中段8个台站分量式钻孔应变仪观测资料的质量。认为各台资料均达到了国家应变台站的观测标准,数据质量可靠,其中观测精度较高的有巴仑、榆树沟、库米什和石场等台。By using the tidal factor internal accuracy,relative calibration internal accuracy,surface strain correlation coefficient and other indicators,the paper comprehensively compares and analyzes the quality of observation data of component borehole strain meter at 8 stations in the middle Tianshan.The results show that the data of each station has reached the observation standard of the national strain station,and the data quality is reliable.Among them,Balun,Yushugou,Kumishi and Shichang stations have higher observation accuracy.Part of the stations have the high precision such as Baluntai,Yushugou,Kumishi and Shichang.
