| 摘 要： | 根据电磁场基本理论及电子运动守恒方程，导出圆锥传输线横向空间电荷流的数值模型和磁绝缘临界条件。通过数值计算，讨论了电压及圆锥几何结构参数等对横向空间电荷流和磁绝缘性能的影响。电压较高时,无磁场的空间电荷流较大，而磁绝缘性能更好。在传输线的三个几何参数中，几何因子对传输性能影响最大。

| Abstract: | Electromagnetic field theory and electron motion conservation equations are used to derive numerical model of transverse space charge flow and magnetically insulated critical condition in conical transmission lines. Through numerical calculation, we have discussed the influence of the voltage and the cone's geometrical parameters on the transverse space charge flow and magnetically insulated performances. The higher the voltage is, the larger the space charge flow without magnetic field, and the better magnetically insutated performances. The geometrical factor K in the three geometrical parameters of the lines has the greatest influence on the transmission performances. |
