摘　　要：为了研究磁场环境对自蔓延高温合成的影响，从而利用磁场环境合成出所需材料，本文设计和制作了用于开展磁场环境下自蔓延高温合成（SHS）材料试验的强磁体。通过永磁铁磁场和通电线圈产生磁场的叠加。在实验区域产生特斯拉级强度。其中的关键技术有：同时改变永磁铁磁场方向或通电线圈中电流大小。实现连续改变实验区磁场强度（0－1T），采用蓄电池供给短时间大电流。与同等强度的传统磁体比较．该磁体重量和成本降低1／10。Recent researches show that materials with special structures and properties can be acquired with the aid of magnetic field. In order to explore the phenomena of SHS under strong magnetic field, we design a new method for obtaining a strong magnet and study the feasibility in practice. The magnetic field of the experiment area is a superposed field, one part is generated by permanent magnet, and the other is generated by electric solenoid. The superposed magnetic intensity can be changed by changing the current in the solenoid or the direction of permanent magnets. The results of experiments demonstrate that our method is feasible and can meet the requirement of scientific research.
