我们考虑了具有16种超对称的场论，其中包括各种维的U（N）杨-米尔斯理论，并论证了它们的大N极限与某些超引力解有关。我们通过考虑弦理论中的D-膜系统来研究这个问题，然后在膜世界体积理论与引力的关系中取一个极限。同时，我们研究了相应的D-膜超引力解，并认为我们可以相信它在某些区域的曲率（和有效的弦耦合，在适当的情况下）是小的。超重力解通常有几个弱耦合区域，并在弦M理论的不同极限之间插值。{版权} {美国物理学会}
We consider field theories with sixteen supersymmetries, which include U(N) Yang-Mills theories in various dimensions, and argue that their large N limit is related to certain supergravity solutions. We study this by considering a system of D-branes in string theory and then taking a limit where the brane world volume theory decouples from gravity. At the same time we study the corresponding D-brane supergravity solution and argue that we can trust it in certain regions where the curvature (and the effective string coupling, where appropriate) are small. The supergravity solutions typically have several weakly coupled regions and interpolate between different limits of string M theory. {copyright} {ital 1998} {ital The American Physical Society}
