transit angle meaning in Chinese

非越角
飞越角

Meanwhile by using numerical method , the beam ' s one - order current density , and the power exchange between the beam and the field are solved . curves are given to illustrate the relations among the above solved parameters and the gap ' s transit angle in different electron velocity and number density
然后通过数值求解得到了不同初始速度和电子数密度时径向间隙中一阶电流密度、高频电场、电子束与本征场的功率交换等随间隙直流渡越角的变化规律。
