机械能守恒定律服从力学相对性原理

阐述了机械能守恒定律服从力学相对性原理。     

机械能守恒定律和相对性原理

详细阐述了机械能守恒定律成立的条件及该定律服从力学相地性原理所需满足的条件,回答了《河北师范学院学报（自然科学版）》在１９９７年第２期上赵佩章等同志对本刊多年来氯表的有关文章的批评     

关于力学相对性原理和机械能守恒定律的讨论也谈机械能守恒定律和相对性原理

指出机械能守恒定律是服从相对性原理的.     

"机械能守恒定律是否遵从相对性原理"辨

从两个层次上的相对性原理出发,对“机械能守恒定律是否遵从相对性原理”进行了剖析;并对究竟把什么称作机械能守恒定律更为合理,提出了一些看法。     

相对性原理对普遍定律和非普遍定律参考系变换性质的不同要求——关于协变性疑难的进一步讨论

提出普遍定律和非普遍定律以及“协变”与“可导出”的明确定义，证明狭义相对性原理（及其伽利略近似）要求在惯性系变换下，自然界普遍定律是协变的，非普遍定律不协变但是“可导出”的，一切定律都服从相对性原理，从而进一步解答了由爱因斯坦，朗道关于狭义相对性原理的一种错误表述所引起的“协变性疑难”，还将有关结论推广到广义相对性原理情况。     

力学相对性原理与机械能

本文指出，只包括内势能的机械能定理和机械 能守恒定律满足力学相对性原理．但是，包括稳定外 势能的机械能定理和机械能守恒定律是不满足力学相对性原理的．机械能守恒定律是否满足力学相对性原理，取决于对势能的处理方法，与力学系统受力状态和机械能守恒条件的表述方式无关     

澄清对相对论性原理和协变性的误解

近来有些文章断言,在一个惯性参考系里能量守恒的物理系统,在别的参考系看来能量也一定守恒.实际上这些作者混淆了物理方程式的协变性和相对性原理.本文将澄清这一误解.     

关于力学相对性原理与机械能守恒的来稿综述

关于力学相对性原理与机械能守恒的来稿综述本刊编辑部本刊１９９１年第１１期刊登管靖“力学相对性原理与机械能”一文后，收到河北廊坊管道职工学院白静江、湖北宜昌师专吴恒钦等同志５篇与此有关的文章。由于本刊发排周期较长，不可能组织紧凑的不同观点的讨论，所以只...     

质点系的功能原理和机械能守恒定律的讨论

A modified Lorentz theory as a test theory of special relativity

A modified Lorentz theory (MLT) based on the generalized Galilean transformation has recently received attention. In the framework of MLT, some explicit formulas dealing with the one-way velocity of light, slow-clock transport and the Doppler effect are derived in this paper. Several typical experiments are analyzed on this basis. The results show that the empirical equivalence between MLT and special relativity is still maintained to second order terms. We confirm recent findings of other works that predict the MLT might be distinguished from special relativity at the third order by Doppler centrifuge experiments capable of a fractional frequency detection threshold of 10^–15.     

The Principle of Equivalence and the Twin Paradox

No Heading The canonical twin paradox is explained by making a correct use of the principle of equivalence. The role of the principle of equivalence is to provide a physical agent i.e gravity which can supply the required extra aging to the rocket-bound sibling during its acceleration phase through a gravitational time-offset effect. We follow an approach where a novel variation on the twin paradox is used to connect gravity with the desynchronization in the clocks of two spatially distant, identically accelerated observers. It is shown that this approach removes certain drawbacks of an earlier effort which claims to exploit the equivalence principle in explaining the differential aging in the paradox. * Author to whom all correspondences should be made.
