引力波

Weber claims recently to have observed gravitational waves coming from the centre of the galaxy.

最近，韦伯声称已观察到来自银河系中心的引力波。

The observatory is the largest, most sensitive gravitational wave detector ever built.

它是目前全世界最大的 、 灵敏度最高的引力波探测所。

Each detector can find them only in a certain range of frequencies.

每种探测器都只能在特定的频率范围找到引力波。

Like precession, mountains produce some quadrupole asymmetry, so they will radiate.

山脉也可以像进动那样产生四极不对称， 因此它们也将辐射引力波。

However, these waves can be hard to detect.

但是， 它们发出的引力波很难以探测。
