数学模型用数学语言描述的一类模型。数学模型可以是一个或一组代数方程、微分方程、差分方程、积分方程或统计学方程，也可以是它们的某种适当的组合，型托辊 吸水树脂 天津水处理设备 邯郸断桥铝门窗 唐山防水 检查井模具 沟盖板模具通过这些方程定量地或定性地描述系统各变量之间的相互关系或因果关系。除了用方程描述的数学模型外，还有用其他数学工具，如代数、几何、拓扑、数理逻辑等描述的模型。需要指出的是，数学模型描述的是系统的行为和特征而不是系统的实际结构。
A class of models described in mathematical language. The mathematical model can be a set of algebraic, differential, difference, integral or statistical equations, or some appropriate combination of them. Through these equations, the interrelation or causality among the variables of the system can be described quantitatively or qualitatively. In addition to the mathematical model described by equation, there are other mathematical tools, such as algebra, geometry, topology, mathematical logic, etc. It should be noted that the mathematical model describes the behavior and characteristics of the system rather than the actual structure of the system.
