摘要
准确的传递函数对固体潮信息的变化分析是非常必要的。由于形变仪器的精确度非常高,长期以来只能对电路原理进行传递函数推算。通过阶跃响应法实验来测定DSQ水管倾斜仪传递函数,同时用激光干涉仪与水管倾斜仪输出进行比测,以确定仪器的精确传递函数。
Accurate transfer function is necessary to analyze the change information of earth tide for a long time, the transfer function can only be calculated with circuit principle as the accuracy of the deformation instruments is very high. The transfer function of DSQ tihmeter was determined with step test method, while the output data between obtained were comparied with laser intefferometer and water tiltmeter. Therefore, the transfer function could be more accurate.
