The fluidization mechanism of group C powder under an external magnetic field has been studied.

本文系统地研究了磁场改善C类物料流化质量的机理，并在此基础上推导出气泡大小与磁场强度等操作条件之间的数学模型；本研究还对铁磁性物质在流化床内发生凝聚的现象进行了分析，得到能预报铁磁性物质发生凝聚的无因次数。

The fluidization behavior of group C powder in an axial uniform magnetic field has been studied.

本文研究了轴向磁场作用下C类物料的流态化行为，得出磁场能有效地阻止沟流的发生和限制气泡长大的结论。
