| 摘 要： | 用数值模拟方法,分析计算了疏松型椭圆截面螺线管电流的磁场与螺距、长宽比、管内位置的关系。计算结果表明,当螺距较大时,其磁场分布与密绕螺线管电流的磁场分布相差很大,磁场在空间各个方向都有分量,螺距越大,螺线管越短,垂直于螺线管轴线方向的磁场分量越强;但当螺距较小、螺线管越短较强时,其磁场与密绕螺线管电流产生的磁场基本相同,可用密绕螺线管电流的磁场近似。

| Abstract: | In order to analyses the relation of the magnetic field distribution of loosen ovalshaped spiral tube current with the ratio of length axes to wide axes and screw-pitch and seat in the tube and length of tube,numerical simulation is adopted.The computation result shows that this magnetic field is quite different from that of c close oval-shaped spiral tube current,when the bigger the thread pitch and the ratio of length axes to short axes and the shorter the spiral tube,the stronger the magnetic field of up... |
