我们讨论了引力透镜的引力波合并中子星星双星的背景下，先进的LIGO型引力波探测器。我们考虑预期的观测数据的性质与削减的信号-噪声比，即，\rho>\rho_0.一个先进的LIGO应该看到一个红移分布的非透镜螺旋事件，在红移z_{\rm max} z_{\rm max}处截止。我们计算预期的事件的总数，这是目前由于引力透镜和它们的红移分布的先进的LIGO在一个平坦的宇宙。如果紧凑透镜中的物质分数接近10%，那么先进的LIGO每年应该会看到一些强透镜事件，其中\rho >5。
We discuss the gravitational lensing of gravitational waves from merging neutron star binaries, in the context of advanced LIGO type gravitational wave detectors. We consider properties of the expected observational data with cut on the signal-to-noise ratio \rho, i.e., \rho>\rho_0. An advanced LIGO should see unlensed inspiral events with a redshift distribution with cut-off at a redshift z_{\rm max} z_{\rm max} should be lensed. We compute the expected total number of events which are present due to gravitational lensing and their redshift distribution for an advanced LIGO in a flat Universe. If the matter fraction in compact lenses is close to 10\%, an advanced LIGO should see a few strongly lensed events per year with \rho >5.
