探测引力波

中国已将两颗用于探测引力波的卫星送入预定轨道。

China has sent two satellites for the detection of gravitational waves into planned orbit .

各个观测站均使用一对相互垂直的激光束用来探测引力波。

The waves are detected with perpendicular pairs of laser beams located at each facility .

用磁悬浮陀螺探测引力波的方案&类比方法的一个应用

Detecting Gravitational Waves by Magnetic Suspension Gyroscope & Using the Analogy Method of the Science Methodology

理论估计传到地球上的引力波非常弱，激光干涉引力波探测器被设计用来探测引力波，在没有引力波传来时，激光干涉引力波探测器应该是零输出。

Predicted gravitational wave is very weak in the earth . Laser interferometer gravitational wave detector is designed to observe gravitational wave . Laser interferometer gravitational wave detector is a null instrument when no gravitational wave passes through .

利用磁悬浮陀螺作为探测引力波的天线，在旋转的陀螺减速过程中，可能与某一频率相近的引力波共振，使信息得到放大；

By the using magnetic suspension gyroscope to the antenna of detecting gravitational waves , in the process of deceleration of rotary gyroscope , the resonance may be caused between gyroscope and any gravitational wave with a close frequency , while the signals may be magnified .

科学家们相信有些脉冲星不是完美的球形，且如果是这样，它们应该发射出特定的引力波，LIGO和GEO600将会在几个月后开始探测这些引力波。

Scientists believe that some pulsars may not be perfectly spherical , and if so , they should emit characteristic gravitational waves , which LIGO and GEO600 will begin to detect in coming months .

但如今的重力探测器还不够敏感，不能探测到引力波。

But today 's gravitational wave detectors are not sensitive enough to detect them .

世界上有好几个实验室正在建造灵敏的仪器，希望能探测到引力波。

Sensitive machines are being built in several laboratories throughout the world to detect gravitational waves .

虽然我们至今还没有探测到引力波，但是已经从搜索的成果中衍生出了新技术。

Even though we haven 't detected gravitational waves yet , there have already been technical advancements spun off from the search effort .

毕竟，如果我们能探测到引力波，能发送探测器到彗星上，那我们为什么就不能将垃圾送到离我们最近的星球上去呢？

After all , if we can detect gravitational waves , or send a probe to land on a comet , surely we can send some rubbish to our nearest star ?

引力波于两年前首次被发现，证实了爱因斯坦的广义相对论。最近，三位科学家因首次探测到引力波被授予诺贝尔物理学奖。

Gravitational waves were first directly detected two years ago , proving Albert Einstein 's theory of general relativity , and recently , three scientists were awarded the Nobel Prize in Physics for their work on that first detection .

科学界的共识是，一旦人们能够直接探测到引力波，它对自然科学甚至人类文明巨大的推动作用将开启一个崭新的引力波信息时代，其科学价值和意义将是十分巨大的。

The common sense in scientific circles is : once human can discover gravitational wave directly , which will open an overall new gravitational wave information age for nature as well as for human civilization . It will also brings great scientific value .

故探测这类引力波需要新的探测方案。

Hence , a new detecting scheme for this kind of GW is needed .

相比之下，于2015年9月14日首次探测到的引力波，是由两个29倍及36倍太阳质量的黑洞合并形成的。

In contrast , LIGO 's historic first detection on Sept. 14 , 2015 resulted from a merger of two black holes 36 and 29 times the mass of the sun .
