摘要
设计制作了由永磁材料构成的，能提供均匀磁场的环形磁场。在锗熔体范围内引入此磁场提供的垂直譬场，采用旋转转子法，测定了不同温度不同磁场强度条件下锗熔体的粘度。结果表明，不同的条件下，锗熔体的粘度有不同程度的降低。粘度降低的原因，可以用磁场对运动带电粒子的作用来解释。
An axial magnetic field is designed by using the permanent magnet. It is a magnetic ring. The .magnetic field is introduced in the melt Germanium, and the viscosity of the melt Germanium is measured by using the rotational method, with the variations of the magnetic field intensity and the variations of the temperature. The interaction principle for the melt and magnetic field is anylized. The result shows, when the magnetic field strength reaches 500 Gauss, the viscosity of melt Germanium can be reduced.
