The time-delay dynamic equation is a fundamental concept in the field of mathematical modeling and control theory, describing the behavior of complex systems with delayed feedback. This equation plays a crucial role in understanding various real-world phenomena, including population dynamics, chemical reactions, and control systems. The incorporation of time delays in dynamic equations enables the analysis of system stability, oscillations, and transient behaviors. The study of time-delay dynamic equations has generated a wide range of research interests across different disciplines, contributing to the development of advanced control strategies and predictive modeling techniques. The following sentences illustrate the application of time-delay dynamic equations in different contexts: 1. The time-delay dynamic equation captures the delayed response of a chemical reactor to changes in input concentrations. 2. Time-delay dynamic equations have been instrumental in analyzing the stability of eco-systems with population feedback.

传热学:流体动力学基本方程流体动力学基本方程:将质量﹑动量和能量守恆定律用於流体运动所得到的联繫流体速度﹑压力﹑密度和温度等物理量的关係式。对於系统和控制体都可以建立流体动力学基本方程。系统是确定不变的物质的组合﹔而控制体是相对於某一坐标系固定不变的空间体积﹐它的边界面称为控制面。流体动力学中讨论的基本方程多数是对控制体建立的。基本方程有积分形式和微分形式两种。前者通过对控制体和控制面的积分而得到流体诸物理量之间的积分关係式﹔后者通过对微元控制体或系统直接建立方程而得到任意空间点上流体诸物理量之间的微分关係式。求解积分形式基本方程可以得到总体性能关係﹐如流体与物体之间作用的合力和总的能量交换等﹔求解微分形式基本方程或求解对微元控制体建立的积分形式基本方程﹐可以得到流场细节﹐即各空间点上流体的物理量。 积分形式基本方程 主要有连续方程﹑动量方程﹑动量矩方程和能量方程。 连续方程 单位时间流入控制体的质量等於控制体内质量的增加。它是由质量守恆定律得到的﹐其数学表达式为式中为速度﹔为密度﹔为控制体体积﹔A 为控制面面积﹔为dA 控制面处法线方向单位向量(图1 积分形式基本方程示意图 )。定常流动时上等式右边为零。这时如截取一段流管(见流体运动学)作为控制面(图2 流管内的连续方程 )﹐则有下述连续方程﹕ P1V1A 1=P2V2A 2 式中P1 ﹑V1﹑P2﹑V2分别为A 1和A 2截面上的流体平均密度和速度。 动量方程 单位时间内﹐流入控制体的动量与作用於控制面和控制体上的外力之和﹐等於控制体内动量的增加。它是由动量守恆定律得到的﹐其数学表达式为﹕式中为外部作用於 dA 控制面上单位面积上的力﹔为外部作用於d控制体内单位质量流体上的力﹔通常就是重力。定常流动时﹐上等式右边为零。动量方程用於确定流体与其边界之间的作用力。
