Different mechanisms contribute to T1 and T2. Surface relaxation and bulk relaxation contribute to both T1 and T2. Surface, bulk and diffusion relaxations contribute to T2.
不同的机理对T1和T2都有贡献，表面驰豫和体积驰豫对T1和T2有贡献，表面驰豫、体积驰豫和扩散驰豫对T2有贡献。
Because natural gas and water have different relaxation time and diffusion coefficient, we can use DSM and SSM to identify them.
由于天然气和水的弛豫时间和扩散系数的差异，可以利用差谱分析法和移谱分析法来识别天然气。
The mechanism of elementary redistrib utionand annealing embrittlement during relaxation Was discussed on the viewpoint ofthe activation energy of atomic diffusion in Ni-P amorphous being variables.
本文从非晶中原子扩散激活能可变化的观点出发，对弛豫过程中元素再分布和脆化机制进行了讨论。
The former one was caused by the molecular diffusion from bulk to interface and the latter one was caused by the relaxation of H2D molecules at interface.
液滴扩张和收缩时，H2D分子存在从体相到表面的扩散快过程和分子在表面上的弛豫慢过程两个弛豫过程。
Thus it is important to understand the effects of diffusion on T2 relaxation times due to internal field gradients.
因此理解内部磁场梯度对T2弛豫时间的影响是很有必要的。
