摘　　要：提出全息熵的概念,并与经典熵做了区别.运用全息原理研究发现,具有紫外截止频率与红外截止频率关系的有效场论使得宇宙常数经量子修正后与观测值一致.黑洞中的熵与普通场论中的熵具有不同的意义.黑洞中的熵指Planck尺度的粒子数,普通场论中的熵为电子尺度的粒子数,并作出了简单的证明,获得宇宙的尺度理论值10-25m与可观测宇宙半径的观测值一致.提出了黑洞熵和物质熵本质是一致的,均起源于粒子数.并意外得到另一结论:暗能量、冷暗物质与普通物质的能量相互流动,并用Einstein场方程做了论证,获得一致的结论.The concept of holographic entropy was proposed and compared with the classic entropy. Researches by the holographic principle found that the effective local quantum field theory with UV and IR cutoffs in accordance with holographic entropy bounds was capable of rendering the cosmological constant （CC） stable against quantum corrections. The entropy in the black hole denoted the numbers of particle of Planck scale, whereas the entropy of ordinary field theory was numbers of electronic scale. In terms of the holographic principle we analyzed the entropy once again, which alleviated the CC problem. Cosmological radius obtained agrees with the currently observed 10^-25 m. We argue that the entropy of black hole agrees with the entropy of matter, which originates from particles. Besides, we arrive at another conclusion, the energy of dark energy, cold dark matter, and ordinary matter are flowing among each other. Such a conclusion was demonstrated by the Einstein field equation.
