我们分析了对应于三维、四维和五维场论的各种膜组态，发现了对应于具有四次超势的三维N = 2和四维N = 1超对称QCD理论的膜组态，其中似乎是“隐藏参数”起着重要作用。我们讨论了用膜构造五维N = 1超对称规范理论和超共形不动点，从而得到新的五维N = 1超共形场论。同样的五维理论也以一种令人惊讶的方式被用来描述三维N = 2超对称理论的新的超共形不动点，这些理论既有“电”库仑分支，也有“磁”库仑分支。(C)1997 Elsevier Science B.V.PACS：11.10.Kk; 11.30.Pb。
We analyze various brane configurations corresponding to field theories in three, four and five dimensions, We find brane configurations which correspond to three-dimensional N = 2 and four-dimensional N = 1 supersymmetric QCD theories with quartic superpotentials, in which what appear to be ''hidden parameters'' play an important role. We discuss the construction of five-dimensional N = 1 supersymmetric gauge theories and superconformal fixed points using branes, which leads to new five-dimensional N = 1 superconformal field theories. The same five-dimensional theories are also used, in a surprising way, to describe new superconformal fixed points of three-dimensional N = 2 supersymmetric theories, which have both ''electric'' and ''magnetic'' Coulomb branches.
