生理系统在时域中的动态特性借助于微分方程或微分方程组来描述。写出描述系统的微分方程或微分方程组的过程称为辨识。根据关于该系统的初步资料，可以区分两种极端的识别情况。如果数学模型的结构是已知的，即，需要多少隔室来模拟生理系统，以及它们是如何相关的，则这是参数评估的情况。对于一个结构未知的被测系统，这个问题称为辨识。大多数问题都介于这两种极端情况之间。
Dynamic characteristics of a physiological system in the time domain are described by means of a differential equation, or a system of differential equations. The procedure of writing the differential equation, or system of differential equations describing the system is termed identification. According to preliminary information on the system, two extreme cases of identification may be distinguished. If the structure of the mathematical model is known, namely, how many compartments are needed to model the physiological system, and how they are related, it is a case of parameter assessment. For a tested system of unknown structure, the problem is termed identification. Most problems are somewher in between these two extreme cases.
