关于物质概念的思考

Thinking about the Concept of Matter

摘要: 本文以朴素的自然观考察物质概念，强调质量和能量的同一性，认为电磁现象是物质的内在属性，能量守恒定律和光速不变原理是物质世界演变过程中应遵循的普遍规律。基于上述对物质概念的理解，重新审视经典力学定律，据此协调能量、力、动量、惯性质量和引力质量等基本量的关系，使修正后的牛顿力学定律适用范围扩展到相对论范畴，并举例计算得到了一个太阳质量的临界黑洞半径。

Abstract: In this paper, the concept of matter is examined in plain nature-views; and it emphasizes the iden-tity of mass and energy; the intrinsic property of matter is electromagnetics; and the law of con-servation of energy and the principle of constancy of light velocity are the common rule in the evolution process of the material world. From the above understanding of matter, it reconsiders the laws of Newton’s classical mechanics, and hereby consolidates the fundamental relations between energy, force, momentum, inertial mass and gravitational mass in mechanics. The application scope of modified Newton’s mechanics law is extended to the relativistic domain, giving an example to calculate the critical radius of a black hole of one solar mass.
