摘　　要：为了提高冷源对复杂电磁环境的抗干扰性能,提出了相应的几种电磁兼容性设计方法,如电磁空间分割、机柜屏蔽设计、有效接地等。并对测试后仍存在的电磁兼容问题进行了分析,采取了改进设计,如电磁滤波器加装、屏蔽材料的使用等,从而使设备获得了更为理想的电磁兼容效果。In order to improve anti-interference performance of the transportable cold source in the complicated electromagnetic environ- ment, some EMC design methods are illustrated, for example, the division of electromagnetic space, cabinet shielding, and effective grounding. The remaining EMC problems after testing are analyzed and rectified by installing filters and retrofitting shielding materials. Finally, the desirable EMC performance is reached.
