中文摘要：

本文为了研究手机的低频电磁辐射情况,利用麦克斯韦电磁学理论与比吸收率之间的关系,提出了一种简化的测试模型。基于该模型,采用低频电磁场辐射测试仪,对几款常用的手机进行了低频磁感应强度测试实验。测试结果表明：1.这几款手机均符合国家的公众曝露控制限值的标准,但有些测试值超出了部分其他国家的标准;2.手机在无网络情况下低频辐射最小;3.手机与人体的距离越远,低频辐射越小;4.手机在不充电时低频电磁辐射小于充电时的低频电磁辐射。根据测试实验结果,提出了降低手机低频辐射的建议。

英文摘要：

In order to study the low-frequency electromagnetic radiation of mobile phone, we propose a simplified test model based on the relationship between the maxwell＇s electromagnetism theory and the specific absorption rate（SAR）. Using the proposed model, low-frequency magnetic induction intensity of a few commonly used mobile phones is tested with Low-frequency electromagnetic radiation testing. The experiment results demonstrate that： 1.The phone is consistent with the Chinese country＇s public exposure control limit standard, but some of the test values beyond the part of the standard of other countries; 2. The low-frequency radiation of the mobile phone, which is off from network, is much smaller than the online mobile phone; 3.The longer distance of the mobile phone away from the body, the smaller the low frequency radiation; 4. The lowfrequency electromagnetic radiation of the mobile phone, which is not charging, is smaller than the charging one. According to the experimental results, we put forward some suggestions to reduce the low frequency radiation of mobile phone.
