我们提供了一种有效的方法，通过从暂态存储模型方程中导出的简单代数关系来估计处理速率。该方法基于输运方程，但消除了校准高度不确定（和中间）参数的需要。我们证明，在一些常见的流输运条件下，色散在处理速率的估计中不起重要作用，因此可以忽略。在这种情况下，不需要计算机建模来估计处理速率。我们还推导了代数方程来估计目标溶质（如溶解氧）与代理示踪剂（如resazurin）的处理速率，并表明即使目标和代理反应都以线性比例的速率在完全相同的位置发生，两种体积平均速率之间的确切关系可能是非线性的，并且是传输的函数。然而，目标处理率估计的不确定性与代理示踪剂处理率成线性比例。
We provide an efficient method to estimate processing rates through simple algebraic relationships derived from the transient storage model equations. The method is based on the transport equations, but eliminates the need to calibrate highly uncertain (and intermediate) parameters. We demonstrate that under some common stream transport conditions dispersion does not play an important role in the estimation of processing rates and, therefore, can be neglected. Under such conditions, no computer modeling is needed to estimate processing rates. We also derive algebraic equations to estimate processing rates of target solutes (such as dissolved oxygen) with proxy‐tracers (such as resazurin), and show that even if both the target and proxy reactions happen in exactly the same locations at rates that are linearly proportional, the exact relationship between the two volume‐averaged rates can be nonlinear and a function of transport. However, the uncertainty in the estimation of the target processing rate is linearly proportional to the proxy‐tracer processing rate.
