摘要：
It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale M-susy through the formula Lambdasimilar toM(p)(4)(M-susy/M-p)(8). We point out that a similar relation naturally arises in the codimension two solutions of warped spacetime varying compactifications of string theory, in which nonisotropic stringy moduli induce a small but positive cosmological constant.
