smooth bore meaning in English

滑膛

In theoretical analysis , the motion of radially - emitted electron beam in diode region and drift region has been analyzed , and the relation between radial momentum or current of electron beam and the guiding magnetic field has also been studied , then the possibility to optimize the guiding magnetic field has been derived . the motion of radially - emitted beam electrons in smooth bore magnetron and smooth bore milo has also been studied theoretically . at last , the motion of radially - emitted beam electrons in compound axial and azimuthal magnetic field has been studied
在理论分析中,初步分析了轴向发射条件下电子在二极管区域和漂移区的运动规律,电子径向动量随着外加磁场变化的规律,以及电子束电流随着外加磁场的变化规律,还有二极管区域磁场优化的可能性;分别研究了有轴向磁场时以及有角向磁场时径向发射的电子在光滑阳极结构中的运动规律,最后分析了在轴向和角向复合磁场中电子的运动规律。
