The ground plane should extend far enough ahead of and behind the model so that no local disturbances are introduced . 地板的大小应超出模型前后足够远,以免引起局部扰动。
2.
Scientists can then figure out which signals are from local disturbances and which are from gravitational waves by comparing data from interferometers in different parts of the world 科学家们还将比较分布在世界各地的干涉计的检测结果,以判别信号是真地来自引力波还是来自于本地的干扰。
