重力方法重要的地质应用之一是主要根据重力异常及密度变化追踪构造的边界。
One of the important geological applications of the gravity method is to trace the boundaries of structures across which gravity anomalies and the density contrast differs significantly.
最简单的方法是重力。
当天文学家用这种方法从地球上观测到一颗恒星在另一颗恒星前“走过”时，距地球较近的这颗恒星的重力就如同一个镜头，将较远的那颗恒星的光弯曲并放大。
In this method, when one star passes in front of another, as seen from Earth, the nearer star's gravity ACTS like a lens, bending and magnifying the more distant star's light.
