| 摘 要： | 将负载区域的电流（丝阵电流、阴极板电流、阳极板电流和回流柱电流）离散成电流线或电流面等电流微元，根据毕奥-萨伐尔定律，计算所有电流微元在指定场点的磁场，再通过叠加给出该点的总磁场。研究结果发现:在丝阵外围区域，仅由丝阵电流所产生的磁场偏离无限长直导线磁场公式的值，但全部电流所产生的总磁场与公式给出的值很接近。同时，研究了不同负载结构参数下的磁场分布，结果表明：增加丝根数有助于减小单根丝表面的局部磁场，改善丝阵外围磁场分布的均匀性。

| Abstract: | The magnetic field around a wire-array load of Z-pinch is essential to understand the wire-array ablation and ablated plasma flowing,as well as the following implosion processes.All the currents of the wire-array,return-posts,anode and cathode were divided by many small current lines or current surfaces,whose magnetic field were calculated by the formula of Biot-Savart's law.The total magnetic field was obtained by summing all the fields contributed from all the current elements.The magnetic field contribut... |
