摘要
本文介绍的是地磁场水平分量的一种测量方法──简谐振动测周期法。本实验装置设计新颖、成本低、测量数据准确，数据处理上采用最小二乘法原理，线性好。
A new method of surveying terrestrial magnetic field horizontal component──measuring period method by harmonic motion is presented. This experimental design was put forward with a new idea and the lowest costs, as well as high accuracy. The data is processed by least square method principle and have a very good linear characteristics.
