一种高精度数字地温测量系统

介绍了采用高Ｑ值石英测温晶体组成的高精度数字温度传感器。该传感器在高分辨率和宽温度范围内频率随温度的变化呈线性关系，其主要特点是抗干扰能力强及数字量输出。阐述了由单片机组成的测量系统，它对传感器输出的地温频率信号进行信息处理、数值转换并显示、打印及远距离传输。该系统除用于地温前兆观测外，还用于高精度机械加工的环境温度测量。

STRIKE-SLIP TRANSFORM DEFORMATION ALONG THE NORTHERN BOUNDARY FAULT OF WESTERN QINLING MT AND HAIYUAN FAULT AND INTERACTION BETWEEN THEM AND LONGSHAN BLOCK

Northern boundary fault (XQLF) of Western Qinling Mt makes a feature of complicated geometric texture and multiphase deformation.Structure segments of major belt show left-step spread.Minor geomorphic features,such as mountain ridge,water system,gulch,terrace and alluvial-proluvium fan,etc,are cut by left-lateral strike-slip fault of major belt since middle-late Quatenary period,and a series of NW (NWN) push-up structures are formed in the compression jogs. Four(times) paleo-earthquake events are found.The Longxian-Baoji fault (LBF) of Haiyuan fault belt (HYF) consists of four secondary faults with 70 km width, and has multiphase slip and deformation history,too. The left-lateral reversed strike-slip is dominant since middle Quatenary.The Longshan block,cut and surround by above-mentioned faults,is both the end structure of the most sourthern segment of HYF and the convergence end of XQLF. It is in a strong compression state and uplift from late Cretaceous to early Quaternary, and its deformation is assimilated by the overthrust sheets, contracts and uplift in the block.
