本文首先指出螺线管磁系的特点。其次,简述了未铠装螺线管中心轴线上的磁场强度计算式并提出了螺统管内腔磁利用系数公式。第三,揭示了铠装螺线管磁系的磁场特牲,指出铠装螺线管与无限长螺线管一样,为一均匀磁场,在铁铠未饱和前其磁场强度为H=0.4πIn。螺线管内腔插入铁芯后,其磁场强度的变化规律可用指数方程式表示。
This paper first points out the characteristics of the solenoid system. Secondly, the calculation formula of the magnetic field intensity on the center axis of the unarmored solenoid is briefly introduced, and the magnetic utilization factor formula of the lumen of the spiral tube is proposed. Thirdly, the magnetic field characteristics of the armor solenoid system are revealed. It is pointed out that the armor solenoid, like the infinite solenoid, is a uniform magnetic field whose magnetic field strength is H = 0.4πIn . After the solenoid cavity is inserted into the iron core, the change rule of the magnetic field strength can be expressed by an exponential equation.
