摘　　要：介绍了 IEC 61000-4-20对场均匀性的规定,并采用此标准附录 B 推荐的两种场均匀性评判准则对 GTEMcell 均匀区的场均匀性进行了评定,发现采用两种不同的评判准则时,GTEM cell 场均匀性的符合性评定可能会获得不同的结论。对产生不同结论的原因进行了分析,并提出了建议。This article introduces the requirements for the electromagnetic field uniformity in IEC 61000-4-20 and two methods are used to analyze the field homogeneity of the uniform area of the GTEM cell which are recommend by Annex B in IEC 61000- 4-20. The authors found two methods possibly result in two different conclusions to validate whether the uniformity of the GTEM cell can be meet the requirements of 61000-4-20. The cause of different conclusions is analyzed and some suggestions are given in the end.
