重力红移 meaning in Chinese
gravitational redshift
Examples
- This effect , known as gravitational redshift , is not specific to black holes
这种称做重力红移的效应，并不是黑洞所特有。 - It also alters the frequency and timing of signals between , say , orbiting satellites and ground stations
举例来说，当讯号在轨道卫星和地面基地之间传递时，其频率和时间也会因重力红移而改变。 - However , it is impossible for astronomers to see the even horizon directly due to the current technical limitation . therefore what scientists discovered so far is only an indirect evidence of the gravitational redshift or similar phenomenon caused by black holes . but those results undoubtedly become an important bridge for linking black hole theory with actual observation
虽然目前的观测技术尚未允许我们直接看到黑洞的视界，所以有关黑洞产生的重力红移或者类似的观测结果都不是决定性的，但这些结果无疑会成为连系黑洞理论和实际观测的重要桥梁。 - They found two events showing the shortening of pulsating cycle and decaying of radiations intensity . the signatures matched theories of what scientists would predict to see . when matter is falling so close to the event horizon , it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人员分析了极大量来自致密天体天鹅座xr - 1的紫外线辐射，发现其中两组数据显示，辐射脉冲的周期随时间缩短，而其强度则随时间衰减至消失，这现象与一些物质在接近黑洞视界时绕著黑洞急促旋转，放出的辐射因为重力红移而衰减的情况相符。
