力线
The equation of the magnetic line of force induced by a circular current is derived. The distributional patterns satisfying the equation are drawn by mathematical software MatLab.
从圆电流的矢势出发,导出了其磁感线所满足的方程,运用数学软件MatLab绘出了其磁感线的分布图。
Hence only one line of force can pass through each point of the field.
因此电场中任一点只能通过一条电力线.
Good-it is showed that line of force of fracture is good but bad paratope in inboard bone cortex from x-ray.
复位差:在正、侧位X线片上显示骨折力线差,骨折块分离明显,内后侧骨皮质严重缺损。
