摘　　要：本文提出了改进磁变仪布局的必要性和布局标准．对磁变仪定向及其稳定性、标度值稳定性和分量仪间允许的最小间距进行了研究，提出了可以提高磁变仪记录质量的改进布局和满足布局全部标准的新布局．改进布局特别是新布局可以显著提高磁变仪保持定向、抗干扰能力，获得记录标度值稳定的较理想的磁照图．In this paper, the necessity of improving magnetic variometer deployment and the criteria are discussed, the orientation of needle and its stability, the scale value stability and the minimum admitted distance between various components are studied. A new deplopent to hove magnetic variometer and to satisfy the three criteria is given After that, a stable scale value recording can be obtained.
