摘要
超引力等量子引力基本理论包含对宇宙学常数有贡献的四形式场强。将这样一个场纳入我们的开放暴胀理论（hep-th/9802030）中，允许对宇宙学常数问题给出一种人择解，其中宇宙学常数对今日宇宙密度给出微小但不可忽略的贡献。我们包含了对我们的解中奇点作用的讨论，以及对 Vilenkin 近期批评（hep-th/9803084）的回复。

备注
11 pages, RevTex file. Replaced version contains major corrections, including a crucial new surface term, and important additions. A connection to eleven dimensional supergravity is made. The anthropic solution of the cosmological constant problem now holds with a real four form in the Lorentzian region. The previously claimed solution to the empty universe problem is shown to be incorrect, but a new solution is suggested
