【摘要】 本文首先回顾了传统的Kaluza-Klein理论,比较详细地综述了Wesson等人提出的五维空时质理论和诱生物质理论。由于诱生物质理论明显体现了马赫原理,故对马赫原理以及以它为基础的Dirac大数假设和Brans—Dicke理论等可变引力理论进行了概括性总结。 随后,在上述理论框架内,从Wesson对运动方程的论述着手,比较四维测地线方程,得到五维空间的零短程线,着重说明质量与无质量粒子同沿五维零测地线运动的观点。最后,根据光速不变原理,对可能存在的附加维提出了相应的思想检验手段。更多还原

【Abstract】 In the former part of this paper, the traditional Kaluza-Klein theory. Give a summarization about 5 D space-time-matter theory and induced-matter idea which advanced by Wesson. As a result of induced-matter theory embody Mach principle obviously, so the variable-gravity theories based on Mach principle are briefly reviewed, such as Dirac’s big number hypothesis and Brans-Dicke theory.Subsequently, in the frame about these theories, begin with the equation of motion that Wesson talking about, compare with the AD Geodesics equation, we can receive the Null Geodesics in 5 D Manifolds, then we’ll explain why could mass particle and none mass particle all move along the Null Geodesies in 5 D .At last, according to the invariability of velocity of light, we bring forward a method to check up the extra coordinate.更多还原
