结果表明，当相关长度增大时，相速度的过渡带向低频方向移动，衰减的弛豫峰随相关长度的增大向低频方向移动，且幅度逐渐减小。
The results show that the velocity and the relaxation peak of the attenuation moved to low frequencies, and the amplitude of the attenuation decreases, as the correlation length increases.
实验表明，顺磁离子能加快水相的核磁共振弛豫衰减速度，而对油相信号没有影响。
These experiments illustrate that paramagnetic ions imbibed in rock brine can shorten the relaxation time of the water protons, but can't effect the relaxation time of oil protons.
