As the GPS method is different from deformation measuring methods with extensometer and horizontal pendulum tiltmeter at the aspect of having source, point observation, data composition, data deleting, data preprocessing, comparing datum,the sole basic data and so on.
由于GPS观测方法在有源性、点观测、数据成分、数据剔除、数据预处理、比较基准、基础数据的惟一性等方面,与伸缩仪、水平摆倾斜仪等形变观测方法存在相当大的差异,为了了解GPS测量的特性,选择固体潮为观测对象,比较了GPS与伸缩仪等形变观测仪的异同。
One example circuit that has been successfully applied to Digital Azimuth-Level Detector is also presented.
SET/RESET电路是配合磁阻式磁强计使用的必不可少的外围电路之一,本文阐述了SET/RESET功能的原理,分析了设计SET/RESET电路的出发点,介绍了SET/RESET电路的一个实例,并且将它应用于微型方位水平仪,取得了良好的效果。
