Sound can travel through water for enormous distances, its ascount energy prevented from dissipating by boundaries in the ocean created by water layers of different temperatures and densities.一个句子 , 直接+名词 （its energy )这样的结构可以么？？？？？总觉得怪怪的
后半句不是一句话，是短语，补充说明声音传播的 its ascount energy 1)prevented from dissipating by boundaries in the ocean 2)created by water layers of different temperatures and densities
