捕捉过程是这样的，因为低频波可以传输到更远的距离，当它们遇到地下的空穴或其他物体反射回来的时候，已经距地面的接收装置很远了。
The catch is that because low-frequency waves can travel great distances, when they do bounce off cavities or objects underground, they often end up far from the detection equipment at the surface.
人类大脑的视觉中心无法准确的判断物体的距离，尤其是对于诸如月球之类较为遥远的距离。
