摘　　要：阐述电磁波对人体的影响可测试参数比吸收率的定义、测试方法和测试系统,分析影响移动电话比吸收率的主要因素,重点研究移动电话附件充电器对移动电话比吸收率的影响,提出充电器对移动电话的等效天线影响模型,并通过实际的测试数据来验证模型。基于模型提出降低充电器对移动电话比吸率影响的改进措施,为移动电话设计提供参考依据。The definition, test method and test affects the human body by electromagnetic wave system of specific absorption rate （SAR） which are described. Equivalent antenna model of the charger for mobile phone is proposed according to the result of studying the impact on the specific absorption rate for mobile phone. The model which is validated by actual test data shows that the charger of mobile phone has important impact on SAR. Improvement measures based on the model are proposed to reduce the value of SAR for mobile phone. It can provide reference for the design of mobile phones.
