摘　　要：手机与人体相互作用涉及两个方面问题:一是手机辐射对人体的作用;二是人体对手机的辐射特性所造成的影响。基于电磁辐射可引起生物组织温度升高且大脑又是对温升最为敏感的组织之一的考虑,用时域有限差分法(FDTD)数值计算了单一方向频率900 MHz和1800 MHz,功率1 W手机辐射时头颅第90层横剖面内温升及Z轴方向温升最大值分布规律。结果表明:越靠近手机温升效果越明显,最高温升位于头颅耳朵附近,900 MHz时头颅最大温升略高于1 800 MHz且沿Z轴温升最大值分布规律几乎一致。The interaction between human and radiation of cell phone involves two problems. One is action of mobile phone irradiation on the human body; the other is effects the body will have on the radiation characteristics of cell phone. For the consideration of the temperature rise of biological tissues caused by electromagnetic irradiation and the brain is most sensitive to temperature, the temperature distribution of 90th floor cross section and the distribution law of maximum temperature along z axis of the skull with the irradiation of cell phone along a single direction were analyzed and calculated by FDTD method, the cell phone work at 900MHz or 1 800MHz and has 1W power.The result shows that the closer the phone, the more obvious of temperature effects and the maximum temperature is around the ear, the maximum temperature in the skull of 900MHz is slightly higher than that of 1 800 MHz and the distribution law of maximum temperature along z axis is almost unanimously to 900 MHz and 1 800MHz.
