摘要
为实时测量微波场强分布，一种基于测量微波热效应的测量装置研制成功。该装置将负温度系数的热敏电阻放入封装适量特殊液体作为吸收介质的玻璃管内做成特殊的液套式测温计作为复合传感器，并由仪器用放大器和数字显示电路等组成电路。该装置使用方便，可安全、可靠、实时地获取微波场分布的信息。
A effect thermometer for measuring both Specific Absorption Rate(SAR) in the biological medium and microwave field distribution in the air.A bulb with an absorbent medium in which a thermal electric transducer is emerged is used as the detector.An electrical circuit was designed specially to adapt the signal thransformation.A lot of assays were done to examine the sensity and linear degree.The results were verified rather satisfactory.
