摘要高斯法测地磁场实验中，悬线的扭力不能忽略。本文通过改进实验装置，测量了悬线的扭转系数。绷紧的悬线不但提高了地磁场水平分量 B_∥ 的测量精度，而且可应用在地磁场垂直分量 B _⊥ 的测量中，两者误差分别控制在 3．0%与 6．7%以内。扭力矩的巧妙利用，为地磁场两个方向的测量提供了新思路。

Abstract: In the Gauss method for measuring of the geomagnetic field，the torsion of the hanging wire cannot be ignored．In this paper，we report the measurement of the torsion coefficient of the hanging wire in the Gauss method．By improving the experimental setup，the tension wire not only improves the measurement accuracy of the horizontal component of the geomagnetic field B ∥ ，but can also be applied in the measurement of the vertical component B ⊥ ，with the errors of 3．0% and 6．7% respectively． The utilization of the wire torque provides a new idea for the measurement of the two components of the geomagnetic field．

Key words: Gauss method horizontal component of the geomagnetic field vertical component of the geomagnetic field wire torque;torsional moment
