ObjectiveTo study the combined test method of electromagnetic environment and nature environment.Methods As required by equipment combined test of multi-physical fields, electromagnetic environment and temperature/humidity envi-ronment, the problem of compatibility of different environmental simulations was solved based on the technology of electro-magnetic reverberation chamber. By analyzing and designing key components, the combined test system was tested in com-pliance with relevant standards. According to IEC61000-4-21, the field uniformity of electromagnetic environment and nature environment combined test chamber was tested under the condition of normal temperature, high temperature and low tempera-ture.Results Results showed that the maximum value of combined field uniformity was less than 3 dB. The performance met the requirements of the standard.ConclusionThe combined test method based on the technology of electromagnetic reverbera-tion chamber is provided for effect mechanism study and adaptive test of equipments under combined effects of environmental stress.%目的：研究电磁环境与自然环境综合试验方法。方法针对装备电磁环境与温度、湿度环境的多物理场综合试验需求，基于电磁混响技术，解决不同环境模拟相容性问题，对关键部件进行分析和设计，并依据相关标准进行了性能测试。依据IEC61000-4-21，分别测试电磁环境与自然环境综合箱在常温、高温和低温条件下的场均匀性。结果综合场均匀性偏差最大值小于3 dB，性能满足标准要求。结论基于电磁混响技术的综合试验方法，为装备在多重环境应力综合作用下效应机理研究和适应性考核提供了手段。
