理解你的核心动力分布，你能计算使用扩散理论，但是核心动力分布创造了一个流量。

To understand that you have core power distribution that you can calculate using diffusion theory but that core power distribution creates a flux.

在这样的情况下乙酰胆碱酯酶将以简单扩散的方式进入唾液，因此它的活性必将和唾液流量速率相关。

However, under these circumstances cholinesterase would enter the saliva by simple diffusion and therefore activity should be correlated with salivary flow rate.

还给出微泵流量与扩散管长宽比、厚宽比、液体粘度和进出口反压差的定量关系。

Quantitative relations of the pump flow rate versus the ratio of diffuser length to width, the ratio of diffuser thickness to width, fluid viscosity and backpressure were also given.
