摘要
使用电子仪器进行测量，尤其是精密测量时，电磁干扰会严重影响测量结果。为此，介绍了接地、连接线布置、屏蔽、浮置、滤波５种常用的抗干扰方法，并且指出，对电子产品进行测量时，测量人员要善于分析测量结果，排除各种干扰，才能提高测量的准确性和数据的可靠性。
Electromagnetic interference has a strong impact on the measurements,espe- cially precision measurements with electronic insruments.Therfore,the authors describe five anti-interference methods, i.e.,grounding,disposal of the lines,shielding,floatation and filtering.It is concluded that measurers should exclude vari- ous interferences on the measurement to improve its accuracy and the reliability of the data.
