Meanwhile the effect of the initial electron velocity on the movement track is also studied 同時(shí)研究了電子的初始出發(fā)速度對(duì)電子運(yùn)動(dòng)軌跡的影響。
But if the electron velocities are high enough ? at least six million meters per second , or about 2 percent of the speed of light ? the drag force actually decreases the faster the electrons go [ see illustration on page 69 ] 但如果電子的速度夠高(至少每秒600萬公尺,約相當(dāng)于光速的2 % ) ,則電子行進(jìn)越快,阻力反而越小(見91頁(yè)曲線圖) 。
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 然后通過數(shù)值求解得到了不同初始速度和電子數(shù)密度時(shí)徑向間隙中一階電流密度、高頻電場(chǎng)、電子束與本征場(chǎng)的功率交換等隨間隙直流渡越角的變化規(guī)律。
