| 摘 要： | 对长距离磁绝缘传输线（MITL）的传输效率和结构变化带来的影响进行了评估。介绍了MITL稳态流与非稳态流理论，为了验证各种条件对传输效率的影响进行了粒子模拟，修改了MITL的结构并设计了若干对应的分解检验实验。通过准确测量同一位置的阴阳极电流和电压验证了Mendel层流理论公式。已完成的电感支撑阴阳极实验结果表明,使用合适量级电感型刚性弹簧对内外筒进行固定可以满足传输效率设计要求。

| Abstract: | This paper evaluates the power transmission efficiency of long magnetically insulated transmission line(MITL) and the effects caused by MITLs structure changes. The steady state flow theory and unsteady state flow theory of the MITL have been introduced. The particle-in-cell simulation and corresponding validation experiments have been conducted. The formula for Mendels arbitrary momentum model after laminar flow approximation are verified by the accurate measurement of the cathode current, anode current and interpolar voltage in the same position. Experiment results of the inductance-supported MITL show that by using the rigid spring of appropriate inductance to fix the internal and external tubes, the requirements of the transmission efficiency can be satisfied. |
