摘要
从矢量迭加的地磁屏蔽基本原理出发，建立了一套设计地磁屏蔽装置的计算机程序，计算并获得了最佳方案，研制成了满足高能高分辨电子能量损失谱仪要求的地磁屏蔽装置．
A computer program to design the shielding deviCe of earth's magnetic field is set up, according to the principle of vector addition of earth's magnetic shielding. The best desigh scheme is obtained.The shielding device is built and it satisfies the high energy high sesolution electron enersy lossspectrum.
