摘　　要：为了验证当前电磁辐射测试国际标准(IEC/IEEE 62209-1528:2020)中涉及的时间平均算法的可行性,首先梳理了相关的测试方案,通过对一款具备时间平均算法的手机按照国际标准给出的方案分别进行了时间平均传导功率和电磁辐射测试实验,得到所需时间平均SAR的TX因子,根据实验过程及数据尝试提出时间平均SAR在cDASY6和cSAR3D上测试所遇到的问题改进建议,最后给出下一步的研究方案,为后续时间平均技术电磁辐射测试提供参考。In order to verify the feasibility of time-averaging algorithm involved in international standards(IEC/IEEE 62209-1528:2020)for EMF(electromagnetic field radiation)test,the article begins with compare the documents,and the time-average conducted power test and the time-average electromagnetic feild radiation test experiments were carried out on a mobile phone with a time average algorithm in accordance with the scheme given by the international standard.The result is the TX factor that requires time-averaged SAR,according to the experimental tests and data,try to propose improvement suggestions for the problems encountered in the time-averaged SAR(specific absorption rate)test on cDASY6 and cSAR3D,and forecasted next step work to provide a reference for the follow-up time-averaging algorithm in EMF test.
