摘　　要：讨论了交流电磁轭的关节与磁粉检测灵敏度的关系。当采用多关节时,在一般情况下,检测灵敏度不会下降。但在多关节磁阻较大,且电源功率又有限时,则有可能引起检测灵敏度下降。This paper discusses the relationship between AC electromagnetic yoke and testing sensitivity. Usually the multi-joints would not lead to a decline in sensitivity. But it may happen when the reluctance is high and the electrical power is limited.

关 键 词：电磁轭 多关节 磁阻 磁通 检测灵敏度
