量度微波生物效应的实验剂量学研究进展

微波剂量学是对沉积在生物体内的微波能量及其分布的物理量度。它通常用比吸收率（SAR）来表示生物效应和作为防护限值量，SAR不仅与入射微波有关，还与生物体的电特性、尺寸、形状、结构有关。本文综述了几种确定SAR的实验方法，包括能差法、电场法、测温法、量热法和热像法，并对其用途和误差来源进行了分析。

Research advances in experimental dosimetry of microwave bioeffects

M icrowave dosim etry is to quantify the m agn itude and d istribution of absorbed m icrowave energy deposited in b iological sub jects.The spec ific absorption rate(SAR) is used to describe cause-effect relationsh ip and to m ake protection lim it.TheSARis related not on ly to the inc identwaves but also the electrical and geom etric characteristics of the sub jects.In th is paper som e experim ental techn iques for determ in ingSARsuch as d ifferential-power techn ique,imp lantab le electric-field probes,temperature probe techn iques,calorim etric techn iques,and thermograph ic techn iques are described.The util-ity and the error sources for each m ethod are reviewed also.
