For long, people mostly get the inducedmagneticfield of under-water aircrafts through the experiment of physical model.
长期以来，人们主要通过物理模型实验来获取水下航行器的感应磁场。

The application of the inducedmagneticfield in surface plasma jet metallurgy, from the influences of freezing morphology, purification and phase transformation were summarized.
论述了磁场对凝固组织，净化以及相变的影响，分析了自感生磁场在等离子束表面冶金中的作用。
