2.相位对比法(PC) TOF法的基础是纵向弛豫,而PC法的基础是流动质子的相位效应(phase effect)。当流动质子受到梯度脉冲作用而发生相位移动,如果此时再施以宽度相同极性相反的梯度脉冲,由第一次梯度脉冲引出的相位就会被第...

Centering of planets is normally affected by their phase effect. Therefore it is necessary to study how to effectively eliminate the phase effect for high -precision centering of planets.
通常,行星位置测量都会受到相位效应的影响,因此研究如何在非零相位的情况下有效消除相位效应的影响对于高精度的行星定心是非常有必要的。
