摘要 简要介绍了引力透镜,NFW质量分布模型的基本原理.详细讨论了星系团Abell 2218的NFW质量分布模型在强引力透镜的应用,估算了星系团的质量及个别背景星系的红移,并对这些结果进行了分析与讨论. This article briefly introduces the basic principles of gravitational lens and NFW mass distribution model. We discuss the applications of NEW model of cluster Abell 2218 in strong gravitational lens in detail, estimate the mass of 3.2218 and the redshift of some individual background galaxies. Finally, we analyse and discuss its result.
