角向磁场 meaning in Chinese
poloidal magnetic field
Examples
- The least load current to realize magnetic insulation in milo is obtained from the relation between current and azimuth magnetic field and the relation between magnetic field and electron movement track
根据电流与角向磁场的关系和磁场与电子运动轨迹的关系得到在milo中实现磁绝缘所需要的最小负载二极管电流。 - Then with the introduction of the expression of radial electric field and azimuth magnetic field , the movement tracks of electrons in the interaction space are modified on account of the azimuth magnetic field decreasing with the decrease of the axial current
接着，引入同轴系统中径向电场和角向磁场的表达式，并且考虑到轴向电流的逐渐减小会导致角向磁场沿轴向的变化，推出修正后的电子运动轨迹表达式。 - 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。 - In addition to pic method , the numerical computation method is used as a compensation for the study of the characteristics of electron beam . the two methods are used separately to attain the trajectory of axially - emitted electron beam in diode region and drift region , and the trajectory of radially - emitted electron beam with axial , azimuthal , as well as compounded axial and azimuthal magnetic field . three two - dimensional codes and two three - dimensional codes have been made out to compute the trajectories
