| 摘 要： | 宇宙学常数的物理学起源问题被视为现代物理中最重大的疑难之一.从额外维的流形出发,给出了宇宙学常数的Bulk时空流形起源的理论.从而得到了不同情况下宇宙学常数的取值和宇宙学常数随时间变化的函数,并且得到了可拟合现代天文观测的宇宙学常数.

| Abstract: | The physical origin of the cosmological constant is considered to be one of the most difficult and important problems in modern physics. In this letter,the authors show up a kind of origin of the cosmological constant from the viewpoint of some extra dimensional spaces, obtaining different values of the cosmological constant under different circumstances, acquiring the evolution function with time and achieving a cosmological constant that may be fitted with modern astronomic observation. |
