摘要: 从层流模型出发，根据线电压和线电流，给出了磁绝缘稳态时传输线极间的电磁场分布的解析表达式。在此基础上，计算了考虑空间电子效应后处于磁绝缘稳态的传输线等效分布电感和电容，以改进磁绝缘稳态的电路单元模型。利用该方法，模拟计算了Z加速器的MITL-A在磁绝缘稳态时的等效分布电感和电容。结果表明，等效分布电容随空间电子效应的增强而变大，而等效分布电感随空间电子效应的增强而变小；且线电压越低，等效分布电感和电容随空间电子效应的增强变化越快。Abstract: Based on laminar flow model, the analytical expression of the electromagnetic spatial distribution in the transmission line under the magnetically insulated stable state is presented from line voltage and current. On that basis, the equivalent inductance and capacitance of the transmission line under the magnetically insulated stable-state are calculated in consideration of the space charge effect for the improvement of unit model of circuit code. With the method presented by this paper, the equivalent inductance and capacitance of MITL-A of Z accelerator under magnetic insulated stable state are computed. The result shows that the equivalent capacitance increases with the enhancement of the space charge effect while the equivalent inductance decreases with the enhancement of the space-ele
