coefficient of dispersion
- 在井巷紊流传递过程中,纵向弥散系数远远大于紊流扩散系数。
In mine mass transfer the longitudinal dispersion coefficient is by far greater than the turbulent diffusion coefficient. - 目的通过对大鼠脑梗死模型不同表观弥散系数(ADC)值测量方法的比较,选取较为合理、有效的测量方法。
Objective To compare the different measurements of apparent diffusion coefficient(ADC) on rat cerebral ischemia models, selecting the more reasonable and effective measurement. - 与未注酒精组相比较,重症急性酒精中毒存活组大鼠脑的磁共振加权成像均出现异常高强度信号,表观弥散系数值有随时间降低的趋势。
Compared with non alcohol injection group, severe alcoholism live group showed high signal on DWI image, and ADC value showed decreasing trend with time.
