- Why Bother Looking for Gravitational Waves? 为什么要寻找引力波?
- The ripples are gravitational waves. 这些波动就是重力场波。
- They are likely sources of gravitational waves. 它们很有可能就是引力波源。
- Gravitational waves signals look like sine waves and occur at different frequencies that depend on their source. 引力波信号看起来象正弦波,但根据他们自己的震源有不同的频率。
- When weather changes, baric meeting occurrence wave motion, affect the gravitational wave in atmosphere thereby. 当天气变化时,气压会出现波动,从而影响大气中的重力波。
- For a gravitational wave to be unambiguously identified, it must be detected by more than one instrument. 鉴于重力波显而易见的研究地位,必须投入更多的仪器来进行研究。
- Unfortunately, a passing gravitational wave will make only a tiny change in the distance the laser beams have to travel. 不幸的是,在激光束所经过的路程过程中,行经的重力波只会稍微地对干涉波波长稍微改变一点点。
- That is why gravitational waves are so difficult to detect! 这就是为什么引力波的探测如此困难的原因。
- These spacetime distortions travel as gravitational waves. 这些时空的改变以引力波的形式传递。
- Here is relative motion between wave source and observer in the Doppler effect. That makes observers feel the phenomenon of changing in frequency. 多普勒效应由于波源和观察者之间有相对运动,使观察者感到频率发生变化的现象。
- This is a systematic search of the sky, one location at a time, for any periodic gravitational wave coming from that location. 这是对天空的一次系统的搜索,目标是从某方向来的周期性的引力波,每次只分析一个方向。
- Uphole shooting is a mostly direct and effective method.Similarly, shear wave uphole shooting can be conducted using shear wave source. 微测井一直是解决纵波勘探表层问题最直接最有效的表层调查方法,同样利用横波震源,也可以进行横波微测井采集。
- GEO 600 is a gravitational wave observatory in Hanover, Germany built by an international collaboration of scientists from the UK and Germany. GEO 600是位于德国汉诺威的一个引力波观测站,由来自英德两国的科学家们合作建设而成。

- Then there are plans to examine the gravitational wave background, which would show what the universe looked like a fraction of a second after the Big Bang. 接下来的计划是检查引力波背景,这可以显示大爆炸后瞬间宇宙的样子。
- The square wave source is an impulse source in which digital technique is used.It has the advantages of rigid phase, high frequency stabilization and high antijamming. 方波电源是采用数字技术的脉冲电源,具有相位严格、频率稳定度高,抗干扰能力强等独特的优点。
- Most of the new gravitational wave detection projects are using laser interferometers instead of resonant mass detectors because they are more sensitive. 大多数引力波探测项目都是使用更为灵敏的激光干涉计探测仪而不是共振质量探测仪。
- A series of problems, gravitational wave, hypervelocity of light and others, concerned with physics in the study of astronomy actively in the past few years are also explored. 还探讨了近年来在天文学的研究中比较活跃的与物理有关的科题,如引力波,超光速等问题。
- The usual version of this common question goes something like: "Yesterday you said that LIGO has 4km arms and that a gravitational wave makes the arm length change a little because space is distorted. 这个问题的常见版本类似于:“昨天你们说LIGO的臂长为4公里,然后在引力波扭曲了空间后这个长度改变了一丁点。
