$ 一、引言 在贮频行波管的测试中,已有同志发现,要达到全频段内充分好的贮频,必须具有高精度的旋波线。这里对这个问题作一些分析和研究,可为提高贮频行波管质量提供一些必要的理论根据。通过这个问题的分析,引导出由实测的冷、热驻波比来估计坛益波动量的计算式。为了使用方便,已把计算过程签表化了,并用实验结果和理论计算作了比较,总的趋势是好的。
$ I. INTRODUCTION In the test of storage and traveling wave tube, some comrades have found that in order to achieve sufficient good storage frequency in the whole frequency band, it is necessary to have a high-precision rotational wave line. Here for some analysis and research on this issue, it can provide some necessary theoretical basis for improving the quality of traveling-wave tube. Through the analysis of this question, we derive the calculation formula of altar wave volatility from the measured cold and hot standing wave ratios. For ease of use, the calculation has been tabulated and compared with the experimental results and theoretical calculations, the overall trend is good.
