论物理系统数学模型的一般结构

On the general structure of mathematical models for physical systems

D. H. Delphenich

摘要:

本文提出,任何基于第一性原理(如守恒定律或平衡原理)的物理系统的数学模型都有一些共同的元素,即运动状态空间、动力状态空间、将动力状态与运动状态联系起来的本构律以及对偶原理。于是,运动方程或静力学方程一方面是从运动学状态的可积性出发的,另一方面是从动力学状态的可积性出发的。从各种基本的物理系统给出的例子。

英文摘要:

It is proposed that the mathematical models for any physical systems that are based in first principles, such as conservation laws or balance principles, have some common elements, namely, a space of kinematical states, a space of dynamical states, a constitutive law that associates dynamical states with kinematical states, as well as a duality principle. The equations of motion or statics then come about from, on the one hand, specifying the integrability of the kinematical state, and on the other hand, specifying a statement that is dual to it for the dynamical states. Examples are given from various fundamental physical systems.
