当前,我国为地震预报服务的地磁台,普遍使用核旋仪(CHD-5或 CHD-6型)和质子仪(CZM-2型)观测绝对值,采样办法均采用每天21时(北京时)人工读数,因而往往由于仪器故障或环境干扰等原因,造成超时观测或缺测,致使日均值资料失真,目前对此类现象缺少弥补办法,为此,我们引用订正法校正畸异值和填补缺失数据,对提高月均值的精度,取得了满意的结果。
At present, the geomagnetic observatories for earthquake prediction in our country generally use the absolute value of the nuclear spinodger (CHD-5 or CHD-6 type) and the proton meter (CZM-2 type). The sampling methods are all adopted at 21:00 (Beijing time) Manual readings often result in time-out observations or absences due to equipment failure or environmental disturbances, which distort the daily average data. Currently, there is no remedy for such phenomena. Therefore, we apply the correction method to correct the abnormal value and fill it up Lack of data, to improve the accuracy of the monthly average, and achieved satisfactory results.
