若水合物下方的沉积物捕集了天然气，其声速会更低，由此产生的反射波具有鲜明的特点。
If the sediment underlying a hydrate entraps natural gas, its acoustic velocity will become much lower, resulting in vivid characteristics of reflections.
人们熟知的波的另一个性质是波在碰到障碍物时的反射能力。
Another familiar property of wave is their ability to be reflected when they meet an obstacle.
