引力波探测器

引力波探测器让激光在长两公里、摆成L形的干涉臂上来回反射，从而对这种微小收缩或扩张进行测量。

Gravitational-wave detectors use lasers bouncing off mirrors in two-kilometer-long arms at right angles , like an L , to measure such minuscule contractions or stretches .

目前世界上许多台引力波探测器，其中两台——美国的LIGO，在路易斯安那州和华盛顿有两个观察站；以及欧洲的VIRGO，位于意大利——刚刚对灵敏性进行了升级，它们都将在2015年开始寻找引力波。

Two of the several gravitational-wave detectors currently built - the American LIGO , with two observatories in Louisiana and Washington , and the European VIRGO in Italy - have just been upgraded to boost their sensitivity , and both will start searching in 2015 .

一旦引力波探测器的灵敏度达到足以确定引力波强度时，本文的结果无疑对引力波天文学将是很有意义的。

Once the sensitivity of the gravitational wave detector reaches the level , enough to determine the intensity of gravitational wave , the results presented in this paper will undoubtedly be useful for gravitational wave astronomy in the future .

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 ?

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。

将地球作接收引力波的天线物质，地球就成为了工作在低频段的引力波探测器。

Taken the Earth as material of antenna for receiving gravitational wave , the Earth behaves as a low-frequency gravitational detector .
