本文提出了一个新的具有两个独立转动参数的D=11超引力的1/8超对称相交M膜解。度规有一个非奇异事件视界，近视界几何是$adS_3\timesS^3\times\bE^2 $（就像在非旋转的情况下一样）。我们还提出了一种由Killing旋量确定超引力解的等距超群的方法，并用它证明了对于近视界解，它是$D（2| 1，\alpha）\times D（2| 1，\alpha）$其中$\alpha$是两个3球半径的比值。我们还考虑了我们的解决方案的各种尺寸减少，以及相应的效果，这些减少的Killing旋量和等距超群。
We present a new 1/8 supersymmetric intersecting M-brane solution of D=11 supergravity with two independent rotation parameters. The metric has a non-singular event horizon and the near-horizon geometry is $adS_3\times S^3\times S^3\times\bE^2$ (just as in the non-rotating case). We also present a method of determining the isometry supergroup of supergravity solutions from the Killing spinors and use it to show that for the near horizon solution it is $D(2|1,\alpha)\times D(2|1,\alpha)$ where $\alpha$ is the ratio of the two 3-sphere radii. We also consider various dimensional reductions of our solution, and the corresponding effect of these reductions on the Killing spinors and the isometry supergroups.
