通过对有色金属液体的正反转交替搅拌，使有色金属液体在正反转过程中产生涡流，可获得充分均匀的搅拌效果。
Through the positive and negative alternation of the non ferrous metal liquid, the liquid metal can generate eddy current in the process of positive and negative inversion.
用有限元法对非均匀介质的涡流检测信号进行了数值模拟，并针对检测信号采用逼近的方法预测了表面硬化层深度。
The numerical simulation on the eddy signals was introduced by approaching method based on Finite Elements theory to predict the hardened depth.
计算结果表明涡流损耗不仅沿线圈周长分布不均匀而且在线圈的断面上也不均匀。
The results show that the distributions of the eddy current losses are nonuniform not only along the coil perimeter but also on the cross section of the coil.
