我们讨论了宇宙常数问题的背景下，更高的余维膜世界的无限体积额外的维度。特别是，通过增加更高的曲率项在散装行动，我们能够找到光滑的解决方案的性质，四维部分的膜世界体积是平坦的范围内的膜张力的正值。
We discuss the cosmological constant problem in the context of higher codimension brane world scenarios with infinite-volume extra dimensions. In particular, by adding higher curvature terms in the bulk action we are able to find smooth solutions with the property that the four-dimensional part of the brane world-volume is flat for a range of positive values of the brane tension.
