| 摘 要： | 引力透镜效应已经成为当前探测宇宙中物质分布最有效的工具之一,因其光线偏折不依赖于物质的组分和状态,所以它很适合于探测包括暗物质在内的所有物质在宇宙中的分布.在引力透镜效应的提出及发现基础上,根据引力透镜的分类,分述了强引力透镜、弱引力透镜和微引力透镜,并讨论了引力透镜效应在宇宙学中的应用.

| Abstract: | Gravitational-lens effect has become one of the most effective means for detection of mass distribution in the universe.Because the bending of light doesn＇t depend on material components and state,it is very suitable for detecting dark matter and the distribution of all material in the universe.The discovery of the gravitational-lens effect is introduced in this paper.Meanwhile, strong gravitational-lens effect,weak gravitational-lens effect and micro gravitational-lens effect are introduced respectively according as the classification of gravitational-lens effect.Otherwise,the application of the gravitational-lens effect in the universe is introduced in this paper. |
