| 摘 要： | 应用经典理论的观点阐述磁共振现象,得到了磁共振的条件,并讨论了描述磁共振的唯象理论——布洛赫方程,引入旋转坐标系解出该方程的稳态解,对与拉莫尔进动方向相反的圆偏振磁场可忽略的原因进行了分析。

| Abstract: | The magnetic resonance phenomenon is expounded by viewpoint of classics theory,gaining magnetic resonance conditions,and the Bloch equation which describe phenomenological theory is discussed.By using rotary reference frame,we get steady state solution of this equation and analyze reasons that the effect of circular polarized magnetic filed which is contrary to detection of Larmor precession is ignored. |
