摘　　要：本文将热损伤的产生和影响引入到肿瘤的微波热疗中。运用微波能量比吸收率SAR的分布分析了微波在组织中的传输和吸收过程,并对微波热疗过程中的温度场、热损伤分布以及血液灌注率的变化进行了数值模拟。In this paper, the effects of thermal injury are induced to the microwave thermal therapy of tumor. The transfer and absorption process of microwave are discussed by using the specific absorption rate (SAR) of microwave in bio-tissue. And a numerical simulation is made to analyses the temperature field, thermal injury field and the change of the blood perfusion during the microwave thermal therapy treatment.
