摘　　要：随着智能手机的快速迭代,其功能越来越多样化,随之而来的手机电磁辐射问题不容忽视。基于此,为了研究手机充电对人体所产生的电磁辐射问题,依托DASY比吸收率智能测试系统,测量手机在3种不同规格的充电器充电状态下产生的比吸收率值。结果显示,手机充电使其产生更高的电磁辐射,同时和小功率充电器相比,使用大功率充电器进行充电时,手机所产生的电磁辐射值会更高,但是测量结果均符合标准限值要求。最后,提出减少手机电磁辐射对人体危害的措施,为智能手机电磁辐射研究提供了参考。With the rapid iteration of smart phones,their functions are becoming more and more diversified,and the ensuing electromagnetic radiation problem of mobile phones cannot be ignored.Based on this,in order to study the electromagnetic radiation caused by mobile phone charging on the human body,relying on DASY specific absorp⁃tion rate(SAR)intelligent test system,the SAR value generated by mobile phone charging under three different specifications of chargers is measured.The results show that the charging of the mobile phone makes it produce higher electromagnetic radiation,and compared with the low-power charger,when the high-power charger is used for charging,the electromagnetic radiation generated by the mobile phone will be higher,but the measurement results are in line with the standard limit requirements.Finally,the measures to reduce the harm of electromagnetic radiation of mobile phone to human body are proposed,which provides a reference for the research of electromag⁃netic radiation of smart phone.
