| 摘 要： | 物理学中,采用多种方法以解决同一问题,或一个概念作适当演变引出新概念,或一个公式经适当变换获得新公式.一些相互之间近似的解电路方法、概念、公式,有时虽然只发生了微小的变动,但产生的作用却不容忽视.它可能因新方法的引入使运算量大幅度减少,也可能因建立“理想化物理模型”使研究的问题有导向性,还可能因公式的微小变动使人们很容易地发现了自然现象的内在规律.

Enlightenment of little change about some concepts, formulas and methods in physics |
| |
| Abstract: | In physics, we study many methods just to solve the same probrem; or develop a concept properly to get a new concept; or change a formula properly to get a new formula. The methods, concepts and formulas in solving circuit, which are approximate to each other, although have a little change sometimes, but their actions are innegligible. It may decrease the quantity of operation much more because of adopting the new method, or may change our idea at all in considering question because of the new concept which develops from the old concept; or make it easier for us to find the inner rules of the phenomenon of nature because of the little change of the formula. |
