重力透镜效应
Explanation: http://zh.wikipedia.org/wiki/引力透镜
http://en.wikipedia.org/wiki/Gravitational_lensing
A gravitational lens is formed when the light from a very distant, bright source (such as a quasar) is "bent" around a massive object (such as a cluster of galaxies) between the source object and the observer. The process is known as gravitational lensing, and is one of the predictions of Albert Einstein's general theory of relativity.

由于“重力透镜效应”(gravitational lensing) 的发生,所以才有“重力透镜”(gravitational lens) 的现象。两者的不同在于 "The process is known as gravitational lensing." 这句话上。

有人说“引力”,有人说“重力”,两者所指的是同一个自然现象。
