The decay of RF-induced NMR spin polarization is characterized in terms of two separate processes, each with their own time constants. One process, called T 1, is responsible for the …

核磁共振弛豫时间有两种即t1和t2 t1为纵向驰豫时间,纵向磁化强度恢复的时间常数t1称为纵向弛豫时间(又称 自旋-晶格弛豫时间)。 t2为横向弛豫时间,横向磁化强度消失的时间常数T2称为横向 …

答：t2谱不同于传统的谱图，它的横坐标为对数布点方式，所谓的积分值其实就是谱峰所对应的各离散点的纵坐标求和值。因此，t2谱的积分值并不是真正意义上的积分，而只是沿用了谱图分 …

2018年11月28日 · Mz在弛豫过程中呈指数增长，其时间常数为T1，Mxy在弛豫过程中呈指数衰减，其时间常数为T2. T1弛豫的发生是因为旋转核与周围环境（即晶格，lattice）之间有能量交 …

2020年6月29日 · The process by which the magnetization in the xy plane decays away, over time, to its equilibrium value of zero, is known as T2 relaxation, transversal relaxation, relaxation on …

2007年8月23日 · • T2 relaxation – how long it takes for the spins to lose phase coherence, allowing the net magnetization (M 0) decay to 0 in the xy plane. – Spin flipping (+½ ↔-½) due …

2020年8月1日 · Nuclear magnetic resonance technology is widely used to evaluate the reservoir pore structure in petroleum logging. The NMR T2 spectra can be used to accurately calculate …

T2 relaxation is the process by which the transverse components of magnetization (Mxy) decay or dephase. As originally described by Felix Bloch (1946), T2 relaxation is considered to follow …

2022年4月25日 · In terms of our vector model, T 2 relaxation corresponds to a loss of coherence or dephasing of the magnetization vector. The recovery of magnetization along the z …
