拉莫频率 Gyroradius

(重定向自Larmor radius)

拉莫频率出现在磁共振现象学中,指的是特定自旋在一定主磁场强度B0下会具有的共振频率。数学关系可以简单写为:

f_0 = \frac{\gamma}{2\pi} B_0 \,

其中f0为拉莫频率,以赫兹表示;B0为主磁场强度,以特斯拉表示;γ为旋磁比,为两者间的比例常数,一种特定自旋具有固定值。

Gyroradius 拉莫频率

(重定向自Larmor radius)

The gyroradius (also known as radius of gyration, Larmor radius or cyclotron radius) is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field. In SI units, the gyroradius is given by

where m is the mass of the particle, v_{\perp} is the component of the velocity perpendicular to the direction of the magnetic field, q is the electric charge of the particle, and B is the strength of the magnetic field.
