本文讨论水平分量磁变仪状态函数 S_(dh_)在水分量磁变仪工作中的影响及排除影响的方法。导出了提高计算精度的计算方法。解释了“上,下午基线值差“现象,并指出出现这一现象是定性判断仪器需重新定向的一个判据。文中建议将二次反射水平分量磁变仪光杆距,由《地震台站观测规范》规定的1200毫米增大至2600毫米,并增加磁针 N 极在磁东工作的规定,提出了使仪器接近理想工作状态时有关常数间应满足的关系式。磁变仪是地磁台基本仪器之一、从观测结果得知,一台水平分量磁变仪在不同时间测算出的基线值往往离散较大,磁爆时更为突出,甚至还出现上、下午基线值差。实测标度值也有类似现象。因此影响了水平分量地磁记录资料的质量,在一定程度上限制了资料在地震预报上的使用。本文讨论水平分量磁变仪状念函数在水平分量磁变仪工作中的影响及排除影响的方法。文中符号加脚标”。“表定向值,取设置在地磁场水平强度 H 为30 000伽马(1伽马即 InT)的地区、标度值 S 为2伽马/毫米、光杆距 R 为1200毫米的二次反射水平分量磁变仪做标准(以下简称标准仪).进行分折温度影响不在本文讨论范围。
This paper discusses the influence of horizontal component magnetometer state function S_ (dh_) on the work of moisture content magnetometer and the method of eliminating the influence. The calculation method to improve calculation accuracy is derived. Explained the phenomenon of “difference in baseline value between the upper and the afternoon”, and pointed out that this phenomenon is a criterion for the qualitative judgment of the instrument to be redirected. In this paper, it is proposed to increase the rod pitch of the second-order horizontal component magneto-rheometer by 1,200 mm as specified in the Seismic Station Observation Specification to 2,600 mm and to increase the requirement that the N-pole of the magnetic needle be used in the magnetic field. Relationship between constants should be satisfied when working state. Magnetic strain gauge is one of the basic instruments of geomagnetic station. From the observation results, it is found that the baseline values calculated by a horizontal component magnetometer at different times tend to be large and discrete, and the magnetic explosion is even more prominent. Baseline value difference. The measured scale value has a similar phenomenon. Therefore, the quality of the geomagnetic record data of the horizontal component is affected, to a certain extent, the use of the data in the earthquake prediction is limited. This article discusses the impact of the horizontal component magnetometer memorial function on the work of the horizontal component magnetometer and the method of eliminating the influence. In the text, the target value plus footing “.” Table orientation value is set in a region where the horizontal magnetic field intensity H is 30 000 gamma (1 gamma or InT), the scale value S is 2 gamma / mm, the light rod pitch R is 1200 mm secondary reflection horizontal component magnetometer standard (hereinafter referred to as the standard instrument.) The temperature distribution is not discussed in this article.
