摘　　要：采用有限元方法研究二维混波室结构辐射电流和测量的辐射场平均值的关系,目的是了解混波室测量环境是否能够满足电磁兼容辐射测量的要求。从二维数值计算结果可以看到,观测场的平均值和辐射电流具有很好的线性关系,从而证明混波室可以作为电磁兼容辐射测量的一个有效测试设备。In order to figure out that if the reverberation chamber testing environment can satisfy the request of electromagnetic compatibility radiation measurement,we did some research about the relationship between the radiation electric current of two-dimensional reverberation chamber structure and the average value of radiation field, with the method of finite element method. From the result of two-dimensional numerical calculation, we can see that there is a liner relationship between the average value of observation site and the radiation electric current. Thus demonstrating that reverberation chamber can be very effective testing equipment for Electromagnetic Compatibility radiation measurement.
