提出了一种新的宇宙学全息原理，它规定“宇宙学视界”内的粒子熵不应超过与视界有关的引力熵。结果表明，在Friedman-Robertson-Walker(FRW)宇宙学中，开放宇宙和一类受限的平坦宇宙都符合这一原理，而封闭宇宙则不符合这一原理。我们还发现大爆炸后的膨胀宇宙与宇宙全息术是不相容的。
A new version of holographic principle for cosmology is proposed, which dictates that particle entropy within `cosmological apparent horizon' should not exceed gravitational entropy associated with the apparent horizon. It is shown that, in the Friedman-Robertson-Walker (FRW) cosmology, the open Universe as well as a restricted class of flat cases are compatible with the principle, whereas closed Universe is not. It is also found that inflationary Universe after the big-bang is incompatible with the cosmic holography.
