从牛顿方程到薛定谔方程谈物理概念及其作用

On Physical Conceptions and Their Role from Newtons Equation to Schordingers Equation

从经典力学中的牛顿方程到量子力学中的薛定谔方程，是人类认识自然过程中的一次大的飞跃．由于科学认识的成果都是通过制定各种概念来加以总结和概括的，所以这一过程主要表现在人们用一些新概念来代替或修正旧概念。该文以从牛顿方程到薛定谔方程为例，讨论科学抽象的结果——概念，指出物理概念在物理学及其相关学科发展中的作用。

A great leap in the process ofm ans cognitian of nature is from Newton＇s equation in classical mechanics to Schordinger＇s equation in quantum mechanics Any achievements in the scientific cognition aremade from drawing up various conceptions and summing up.In such aprocess, some new concepticns are used to substitute or am end the old conceptions This paper discussed the achievement of scientific abstract, or conception, based on the examples from Newton＇s equation to Schordinger＇s equation and pointed out the role of physieal conceptions in the development of physics and other related subjects.
