给出了耦合常数为2 = 3的Einstein-Maxwell-Dilaton方程的两类轴对称稳态解。这两个类都是用两个调和映射来写的。它决定了引力势和电磁势，其形式使得我们可以得到任意的电磁场。作为例子，我们生成了两个具有质量(M)、旋转(s)和标量(o)参数的解，一个具有电荷(q)，另一个具有磁偶极子(q)参数。第一个解决方案包含q = o = 0的Kerr度量。
We present two new classes of axisymmetric stationary solutions of the Einstein-Maxwell-Dilaton equations with coupling constant � 2 = 3. Both classes are written in terms of two harmonic mapsand �. � determines the gravitational potential andthe electromagnetic one in such a form that we can have an arbitrary electromagnetic field. As examples we generate two solutions with mass (M), rotation (s) and scalar (�) parameters, one with electric charge (q) another one with magnetic dipole (Q) parameter. The first solution contains the Kerr metric for q = � = 0.
