摘要：

The projected directions of the rotation axes of interacting galaxies tend to align orthogonal to each other. This can be explained in the case that paired galaxies with parallel spins have merged into single galaxies, while those with orthogonal spins survived unmerged. We suggest a "tri-axial" hypothesis for the spin and orbital angular momenta of interacting systems regarding their survival from merging.
