| 摘 要： | 在Ｅ极化、辐射电平１ｍｗ／ｃｍ２条件下，在４０．６８ＭＨｚ～４ＧＨｚ频段内６个频率点上，利用红外热图术观察了６０只Ｗｉｓｔａｒ成年大白鼠，连续辐射１ｈ后，体表及各部位体表温度变化。结果表明，体表温度与肛温变化有很好的一致性，并在１．５ＧＨｚ有最大值。它表明在该频率下，实验鼠吸收射频能量最大，表现出明显的谐振吸引特性。

| Abstract: | The authors observed the temperature changes of various parts on 60 Wistar rat's body surface with infrared thermography. These rats were exposed to 1 mW/cm2 power density of E-polarization RF radiation at 6 frequency POints between 40. 68-4000MHz for an hour. The results revealed that temperature changes on body surface were consistant with rectal temperatures and feached a maximum at 1500MHz' RF energy absorbed by experimental rats was maximum at above frequency and it is shown that experimental rats have obvious feature of resonant absorption at the frequency. |
