从宏观上来看，共振导致磁化矢量M0偏离静磁场B0方向，调整交变电磁场脉

From the macroscopic point of view, resulting in resonance magnetization vector M0 direction departing from the static magnetic field B0, the alternating electromagnetic field to adjust the width of the pulses M0 makes just 90 ° to deflect the xy plane.

From a macro perspective, resonance causes the magnetization vector M0 to deviate from the direction of static magnetic field B0, adjusting the width of the cross-change electromagnetic field pulse so that M0 is just deflected 90 degrees to the xy plane.

From the macroscopic point of view, the resonance causes the magnetization vector M0 to deviate from the direction of the static magnetic field B0, and adjusts the pulse width of the alternating electromagnetic field so that M0 just deflects 90 ° to the XY plane.<br>
