摘　　要：对一种由弱变和强变结构组成的锥形磁绝缘线振荡器的频率特性进行了分析。通过对实验中出现的跳频现象和腔体特性分析对比研究表明,跳频后出现的新的工作模式也属于近π模,但其场结构和稳定π模的场结构明显不同。通过改变提取部分慢波叶片周期开展的验证性实验也表明了分析的正确性。研究表明,匹配的驱动平台、良好的二极管真空度以及合适的二极管位置是锥形磁绝缘线振荡器能够稳定运行的保证。Frequency feature of an S-band tapered magnetically insulated transmission line oscillator with slowly tapered vanes and sharply tapered vanes is analyzed. Comparing the frequency hopping phenomena in the experiments and cavity characteristics analysis for this device shows that the hopped frequency is also π moded and its distribution is different from the stable mode. Experiments by adjusting the period of the sharply tapered vanes have proved the analysis result. Further research indicates that matching driving pulse power source, perfect vacuum and proper diode position ensure stable operation of the tapered MILO.
