由于邻近效应和集肤效应的影响，感应加热时只是工件中靠近外表皮透入深度为定值的一层直接发热，内部发热很少；

Due to its proximity effect and skin effect, induction heating is only the workpiece near the outer skin penetration depth of a layer of fixed value of the direct heating, internal heating is small;

同时给出了几种不同导体电流密度及透入深度的计算结果 ，得出了半径较大的圆导体在考虑集肤效应时可当作平面导体来处理的结论 。

The paper gives the calculated results of current density and depth of penetration, from which we conclude that the conductor with larger r.
