摘　　要：采用有限积分技术,在人体电磁仿真模型上求解了人体组织在低频强电磁场中的电磁吸收剂量。结果表明:人体组织的感应电流密度和比吸收率主要取决于电场强度;在不同的人体组织中,肌肉中的电磁吸收剂量最大,应作为人体安全性衡量指标的主要监测对象。The absorbed dose of human tissues in the low frequency electromagnetic field is simulated by the finite integration technique based on human electromagnetic simulation model.Results show that the induced current density and specific absorption rate in human tissues depend mainly on the electric field intensity,and the muscle,which has the maximum absorbed dose than other tissues,should be the mainly monitoring object in the evaluation for the the safty of human tissues.

关 键 词：有限积分技术 感应电流密度 比吸收率
