关于宇宙常数问题是个至今没有解决的问题,它的来源至今还没有一个共识.从额外维的流形出发,给出了宇宙常数的bulk流形起源的理论,得到了不同情况下宇宙常数的取值和宇宙常数随时间演化的函数,并且得到了可拟合现代天文观测的宇宙常数.

The problem about cosmological constant is a difficult and important problem, people even don't know what it is really originated from. In this letter, we show up a kind of origin of the cosmological constant from the viewpoint of some extra dimensional spaces, obtain different values of the cosmological constant under different circumstances, acquire the evolution function with time t. And we achieve a cosmological constant that may be fitted with modern astronomic observation.
