本文利用Nakai法处理楚雄台水管倾斜仪的观测资料,认为格值比例系数是稳定的;平均时间滞后的变化是均匀的;仪器两天内的二次漂移系数很小,线性漂移系数较稳定,但受到干扰因素影响。根据这些参数和均方误差大小及其变化可以认定观测资料是可靠的,精度是高的。Nakai检验作为形变台站日常工作,除能够识别和纠正错误数据外,是研究各种干扰影响的一种途径。
In this paper, the Nakai method was used to deal with the data of Chixiong Water Pipe Inclinometer. It is considered that the grid scale ratio coefficient is stable. The average time lag changes uniformly. The instrument has a small second-order drift coefficient and a relatively stable linear drift coefficient within two days Affected by interference factors. According to these parameters and mean square error size and its changes can be observed that the data is reliable, the accuracy is high. Nakai’s test, as a routine work on deformable stations, is one way to study the effects of various disturbances, in addition to being able to identify and correct erroneous data.
