研究了具有非平凡结构的厚膜上引力的局域化问题。本文考虑了推广厚Randall-Sundrum解的双壁和由Z{sub 2}对称标量势产生的非对称壁。我们提出了一种新的不对称解：在具有不同宇宙学常数的两个ad {sub 5}时空之间插入一个厚膜，它可以从“假超引力”超势中推导出来，并表明可以将引力限制在这样的膜上。
We consider localization of gravity on thick branes with a nontrivial structure. Double walls that generalize the thick Randall-Sundrum solution, and asymmetric walls that arise from a Z{sub 2} symmetric scalar potential, are considered. We present a new asymmetric solution: a thick brane interpolating between two AdS{sub 5} spacetimes with different cosmological constants, which can be derived from a 'fake supergravity' superpotential, and show that it is possible to confine gravity on such branes.
