The experimental study is performed on the rtto designed with the help of simulation , and the microwave based on radial transit - time effect is obtained . the output power is measured by horn and electric probe and the frequency is measured by a wave - guide dispersion line 实验采用喇叭天线接收和电探针恻量两朴方法时微波功率迭行了恻量,微波颂率用波导色散线法迭行恻量。
The media referred to in this essay is characterized by the time effect in content , comprehensiveness in form and overlap in coverage , and is divided into such four categories as traditional magazine , radio , tv and newly emerging internet 本文所指的传媒,以内容上的时效性、形式上的综合性以及覆盖面上的重叠性作为特征,具体分为传统的报刊、电台电视台与新兴的网络媒体四类。
Based on the analytical solution , the influence of all relevant parameters on the settlement behavior of single pile was analyzed and discussed . 2 . the time effect of the settlement of single pile in layered soil was studied 采用分离变量法求解得到了均质地基中受静力荷载作用的单桩桩顶沉降与时间关系的解析解,并据此分析讨论了各种参数的变化对单桩的沉降与时间关系的影响。
Radial transit time oscillator ( rtto ) is a promising novel high power microwave source based on the radial transit - time effect . it can operate under the condition of low impedance and without external guiding magnetic fields 径向渡越时间振荡器( radialtransittimeoscillator ,简称rtto )是一种前景光明的基于径向渡越时间效应的新型高功率微波源,能在低阻抗、无外加磁场条件下工作。
Under the cylindrical coordinate , the transit - time effect of the radial gap in the resonance cavity of rtto is studied by hydrodynamic theory . the equation describing the interaction between the electron beam and the high frequency field is obtained 在柱坐标系统中,我们用流体理论方法分析了rtto谐振腔间隙的渡越时间效应,得到了在有限渡越角情况下电子束与高频场相互作用的方程。
