在六维环面上压缩的杂交弦理论或II型弦理论的S对偶要求存在带缠绕电荷的Kaluza-Klein双子。我们确定了导致这些双子激发的Kaluza-Klein单极子解的零模，并表明我们得到了S对偶预言的正确的双子简并。欧氏Taub-NUT空间上的自对偶调和二次型在这一构造中起着至关重要的作用。{版权所有}{ITAL 1997}{ITAL The American Physitive Society}
S duality of heterotic or type II string theory compactified on a six dimensional torus requires the existence of Kaluza-Klein dyons, carrying winding charge. We identify the zero modes of the Kaluza-Klein monopole solution which are responsible for these dyonic excitations, and show that we get the correct degeneracy of dyons as predicted by S duality. The self-dual harmonic two form on the Euclidean Taub-NUT space plays a crucial role in this construction. {copyright} {ital 1997} {ital The American Physical Society}
