diffusion time

基本解释

In the certain diffusion time the relation of gas concentration and diffusion depth is parabolic.
得出在一定的扩散时间内，气体浓度与扩散深度之间为抛物线关系；
Characteristic nucleation time and characteristic diffusion time were employed to judge the controlling factor of the nucleation process.
提出采用特征成核时间和特征扩散时间，判定反应沉淀过程的成核控制因素。
It means that the spin diffusion time constant is quite different from the spin-spin relaxation time constant, although the two processes are closely related.
这意味着，自旋扩散时间常数与自旋—自旋弛豫时间常数是很不相同的，虽然这两个相应过程虽密切相关的。
