摘　　要：为了改进肿瘤的微波热疗，我们进行９１５ＭＨｚ微波亚铁磁共振的实验研究。结果表明９１５ＭＨｚ微波象２４５０ＭＨｚ一样，有明显而尖锐的亚铁磁共振升温。实验测量了不同聚集状态，不同饱和磁化强度亚铁磁共振介质的共振升温并用鸡蛋清受热固化来显示共振升温对温度分布的影响。This work studied the effect of temperature elevation of 915 MHz ferrimagnetic resonance in order to improve microwave hyperthermia in cancer therapy. The curves of different collective states, mass and saturation magnetization of resonant media have been measured in different microwave power. Some behaviour of resonant rising temperature under 2450MHz microwave was given to compare to that of 915 MHz.In order to indicate influence of resonance to temperature distribution, photos of solidification of egg white heated by resonance were given too.
