摘    要：对直流大电流条件下工作的计算机受恒定强磁场干扰的现象进行了理论分析及数学计算，探讨了洛仑兹力对计算机屏幕（CRT）的影响，明确了在该环境中保证计算机及其CRT正常工作的位置和必要的措施，指出了屏蔽体壁厚和材料与磁屏蔽效果的关系，为磁屏蔽的设计提供了依据。

Abstract: Theoretical analvsis and mathematical calculationhave been madeon theinterference onthe working Computer under direct-large-current condition caused by strong constant mag-netic-field.The influence of Lorentz force on the CRT has been discussed.The positionwhere the CRT in the system can work normaIly is determined;the influence of shieldingmaterial and its thickness on the anti-inlerference effect is described,and scientific basis forthe design of magnetic shielding ls provided。
