Hyper Suprime-Cam Subaru战略计划（HSC SSP）是一个寻找强大镜头的绝佳调查，这要归功于它的面积，图像质量和深度。我们使用三种不同的方法来寻找透镜43,000明亮的红色星系从重子振荡光谱调查（BOSS）的样品与光度从HSC SSP的S16 A内部数据发布。第一种方法是一种新开发的算法，名为YATTALENS，它寻找大质量星系周围的弧形特征，然后通过执行透镜模型拟合来估计物体是透镜的可能性。第二种方法，CHITAH，是一种基于模型的算法，最初是为了寻找透镜类星体而开发的。第三种方法利用光谱数据来寻找来自与主星系红移不同的物体的发射线。我们发现了15个确定透镜，36个高可能透镜和282个可能透镜。在这三种方法中，YATTALENS是专门为这个问题开发的，在完整性和纯度方面表现最好。尽管如此，YATTALENS遗漏了5个高度可能的晶状体，但其他两种方法发现了，这表明三种方法具有高度互补性。根据这些数字，我们预计在HSC SSP结束时将找到300美元的确定或可能的镜片。
The Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) is an excellent survey for the search for strong lenses, thanks to its area, image quality and depth. We use three different methods to look for lenses among 43,000 luminous red galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS) sample with photometry from the S16A internal data release of the HSC SSP. The first method is a newly developed algorithm, named YATTALENS, which looks for arc-like features around massive galaxies and then estimates the likelihood of an object being a lens by performing a lens model fit. The second method, CHITAH, is a modeling-based algorithm originally developed to look for lensed quasars. The third method makes use of spectroscopic data to look for emission lines from objects at a different redshift from that of the main galaxy. We find 15 definite lenses, 36 highly probable lenses and 282 possible lenses. Among the three methods, YATTALENS, which was developed specifically for this problem, performs best in terms of both completeness and purity. Nevertheless five highly probable lenses were missed by YATTALENS but found by the other two methods, indicating that the three methods are highly complementary. Based on these numbers we expect to find $\sim$300 definite or probable lenses by the end of the HSC SSP.
