摘　　要：从分析力学和经典物理,总结出物理学的一个基本原理是各种守恒原理,其可以推广为广义守恒原理.这包括各种运动量及等比例的物质量守恒定律.由此提出与某些权威对质能关系不同的解释.守恒原理在各个领域的具体形式不同,但是普适的.这些守恒量运动或变化的定量方式、具体过程就是极值原理,它包括广义惯性原理.From the analytical mechanics and the classic physics, we sum up a basic principle, various conservation principles. This may be extended to a generalized conservation principle, which includes various conservation principles on different movement quantities and the equal-proportional matter quantities. From this we propose explanations different from some authorities on the mass-energy relation. The conservation principle possesses different concrete forms for various regions, but it is universal. The quantitative methods and the concrete processes on move or change of these conservation quantities are the principle of limiting value, which includes the generalized principle of inertia.
