The purpose of the current Letter is to give some relations between gravitational lensing in the strong-deflection limit and the frequencies of the quasinormal modes of spherically symmetric, asymptotically flat black holes. On the one side, the relations obtained can give a physical interpretation of the strong-deflection limit parameters. On the other side, they also give an alternative method for the measurement of the frequencies of the quasinormal modes of spherically symmetric, asymptotically flat black holes. They could be applied to the localization of the sources of gravitational waves and could tell us what frequencies of the gravitational waves we could expect from a black hole acting simultaneously as a gravitational lens and a source of gravitational waves.
这封信件的目的是给出在强引力透镜极限下和球对称、渐近平坦的黑洞的拟正则模频率之间的一些关系。一方面，所得到的关系可以对强引力透镜极限参数给出物理解释。另一方面，它们也为测量球对称、渐近平坦的黑洞的拟正则模频率提供了一种替代方法。它们可以应用于引力波源的定位，并告诉我们从同时充当引力透镜和引力波源的黑洞中我们可以预期哪些频率的引力波。
