摘　　要：研究针对在距离人体20厘米以内使用的无线终端设备的电磁波吸收率(Specific Absorption Rate,SAR)进行测量,旨在通过测量所得的SAR值,来评估这些无线终端设备对人体可能产生的电磁辐射危害。为确保测量的准确性和可靠性,需要使用专业的测量系统,并严格按照国家规定的技术标准进行操作,以确保所检测的SAR值符合国家标准限值规定。如果测量出来的结果超过国家技术标准规定的范围,就需要分析SAR的测量数据,以期在保证无线终端不影响信号正常传输的情况下,给出最优化的设计方案来降低电磁辐射对人体的潜在危害。The study aims to measure the specific absorption rate(SAR)of wireless terminal devices used within 20 centimeters of the human body,in order to evaluate the potential electromagnetic radiation hazards of these devices to the human body through the measured SAR values.To ensure the accuracy and reliability of the measurement,it is necessary to use a professional measurement system and operate strictly in accordance with the technical standards stipulated by the country.In this way,it can be ensured that the detected SAR values comply with the national standard limit regulations.If the measured results exceed the range specified by the national technical standards,it is necessary to analyze the SAR measurement data in order to provide the optimal design scheme to reduce the potential harm of electromagnetic radiation to the human body while ensuring that the wireless terminal does not affect the normal transmission of signals.
