这个扩散系数,我们一会就定义出来。
The estimated diffusion coefficient agrees with experiment within an order of magnitude.估计的反常扩散系数在量级上与实验一致。
The extent of water mobility within biological tissues can be quantified by a parameter called the apparent diffusion coefficient (ADC).水在生物组织内的流动程度,可以由一个被称为表观扩散复合系数(ADC)的参数去量化之。
