| 1. | How is this related to time delays in gravitational lenses
这与重力镜中的时间延迟有何关系？ |
| 2. | A gravitational lens is formed when light is bent by a massive object
引力透镜现象就是光被巨大质量物体弯曲的现象。 |
| 3. | " gravitational lens " formed by the gravity of massive galaxy clusters abell 1689 bends and magnifies
大质量星系团阿贝尔1689的重力透镜 |
| 4. | A galaxy cluster acts as a powerful gravitational lens , magnifying and stretching the distant galaxies lying behind the cluster core
星系团起著强大引力透镜的作用，将遥远的星系放大和扭曲。 |
| 5. | For examples , observation of the gravitational lens phenomenon and the scattering phenomenon produced by microwave background radiation and hot plasmas from galaxies clusters
，例如利用引力透镜现象及微波背景辐射与星系团的热等离子体造成的散射现象等等。 |
| 6. | As you may see , the smaller the mass of gravitational lens , the smaller the einstein ring is . on the other hand , if the two objects are close to each other , d
不同旋转速度造成物质之间产生摩擦，摩擦产生热能，结果物质温度上升，当温度达摄氏一百万度时，便会放射出很强的x射线。 |
| 7. | Pasadena , calif . - using natural " gravitational lenses , " an international team of astronomers claim to have found the first traces of a population of the most distant galaxies yet seen - the light we see from them today left more than 13 billion years ago , when the universe was just 500 million years old
加利福尼亚州的一个国际天文学家小组pasadena通过引力透镜效应，宣称发现了最远星系的第一个踪迹，我们今天看到的从那里发出的光是130亿年前发出的，在这个时间，宇宙年龄刚刚5亿年。 |
