Fixture system capable of dynamically testing electromagnetic parameters of powdery material

The invention mainly belongs to the technical field of using microwave to test the electromagnetic parameters of a powdery material in a motion state and particularly relates to a fixture system capable of dynamically testing the electromagnetic parameters of a powdery material. The fixture system comprises a closed circulation system and a free space method test system. The closed circulation system is used for realizing a closed circulation of a powdery material to be tested to make the powdery material to be tested in motion. The free space method test system is used for testing the electromagnetic parameters of the powdery material in motion. The system is a closed space, and the powdery material can only circulate in the system and cannot escape to pollute an environment. The materialcirculates in the system, and a test can be completed with a small amount of material sample. 本发明主要属于利用微波测试运动状态下粉末状材料电磁参数的技术领域，具体涉及种能够动态测试粉末状材料电磁参数的夹具系统，所述夹具系统包括封闭式循环系统和自由空间法测试系统；所述封闭式循环系统用于实现待测试粉末状材料的封闭循环，以使待测粉末状材料呈运动状态；所述自
