摘　　要：为配合国家重点工程需要，本人主持设计量热式水负载五公分１０ＫＶＡ微波大功率计，并对整机的误差进行分析，对量热过程中出现的动态热损，究其产生原因，找出“Ｍ型补偿回路”的有效补偿方法，大大提高大功率的测试精度。The 5cm, 10KVA Water-loading Calorimeter Type Microwave High Power Meter was designed and the error of the prototype was analyzed. The cause of dynamic thermal loss during thermal measuring was study and an effective compensation method was presented to improve the high power measurement accuracy.
