| 摘 要： | 磁绝缘传输线电流损失的计算方法是丝阵Z箍缩电路模拟的关键问题之一。以传输线模拟方法TLCODE为基础，将磁绝缘传输线分成若干段有损传输线单元，每个单元由一段无损传输线及一个对地损失电阻组成，根据磁绝缘准则判断单元的磁绝缘状况，磁绝缘形成之前损失电流由空间电荷限制流与传导电流的定量关系来计算，磁绝缘形成之后则根据阻抗匹配关系及流动阻抗模型来计算；同时将丝阵负载内爆动力学方程与TLCODE表达式、流动阻抗方程进行耦合，可求解磁绝缘传输线、丝阵负载在电压脉冲作用下全时空域的动态响应特性。

| Abstract: | A method of circuit simulation of magnetically insulated transmission line(MITL) driving a wire array to implode has been introduced. Based on TLCODE, an MITL has been divided into a lot of lossy transmission line elements, and each element comprises a segment of lossless transmission line and a grounded resistor. According to magnetic insulation theorem the element states were determined. For the state before magnetic insulation the loss current of each lossy element is calculated by the relationship between space-charge-limited(SCL) flow and conducting current, while for the state after magnetic insulation its loss current is determined by the impedance matching condition between two adjacent lossy elements. The equations describing the wire array to implode, the TLCODE equations, the fl |
