摘要
从描述低速宏观物体运动规律的分析力学中总结归纳出作为这一理论的基础的四个基本原理,即最小作用量原理、相对性原理、时空对称性原理和内部对称性原理,根据它们的内在关系称之为原理四面体.将这一原理四面体推广应用到高速微观运动以及场的运动,讨论了原理四面体在现代物理学中的基础性作用,并说明由原理四面体建立物理理论在更高的水平上体现了“实践-认识-实践”的认识论规律.
Four basic principles, i.e. the principle of least action, the principle of relativity, the principle of space-time symmetry and the principle concerning the intrinsic property of system, are studied in the framework of classical mechanics. These four basic principles are endued with the name of principle-tetrahedron according to their internal relation. The principle-tetrahedron is applied to macroscopic objects with high velocity and to field. Its function as the basis of modern physics is discussed. It is demonstrated that the foundation of physics theory by principle-tetrahedron exhibits the epistemology rule of experiment-theory-experiment in a higher level.
