摘要
我们研究 IIB 型超弦理论中 D-瞬子附近的膨胀子/轴子构型。在场论极限下，瞬子附近的度规在弦框架以及爱因斯坦框架中均变为平直。在大 N 极限下，除原点附近外，弦耦合常数变为零。我们分析了该构型的超对称性。讨论了这一结果对 IIB 矩阵模型的启示。

Major revision; supersymmetry in Euclidean space re-examined. New conclusions: (1) the supersymmetry is not enhanced in the field theory limit. (2) the theory becomes free type IIB string theory in the large N limit, but the limit is not uniform. 9 pages, LaTeX
