And Symmetrical Distribution的意思|示意

且对称分布 This invention relates to a kind of new style high antijamming alternate current / magnetic field sensor, composed by open core's loop and integrating circuit. Two output ports of loop are connect to two input end of compensating type differentiation integral amplifying circuit by wire; the open core's loop has air gap, and symmetrical distribution. connect both end of air gap by non ferromagnetic material with core to form a whole, secondary winding even and reeling on air gap;
