| 摘 要： | 大量可信的证据表明暗物质造成了许多漩涡星系的平坦的自转曲线;在爱因斯坦引力场方程中加入暗能量的能量动量张量后,通过假设星系中的暗能量是非均匀、球对称分布的,同样得到星系NGC3198的平坦的自转曲线,因而可认为暗物质和暗能量是同一种物质的两种表现,初步统一了暗能量和暗物质.

| Abstract: | Many believable proofs indicate that dark matter causes the flat rotation curves of many spiral galaxies. When adding the energy-momentum tensor of dark energy into the Einstein field equations and assuming that dark energy embedded in galaxies is inhomogeneous and spherical symmetric, we can also obtain the flat rotation curves of NGC3198. Thus, we can think that dark matter and dark energy are two properties of one matter, unifying dark matter and dark energy preliminarily. |
