1. Air can be pumped into the diving suit to increase buoyancy. 可以往潜水衣中打气增加浮力。
2. As I gradually adapted to buoyancy, I saw groups of small yellow groupers hiding underneath the dive boat to avoid barracuda. 当我逐渐适应了浮力，就看见成群结队的黄色小石斑鱼为了躲避梭鱼而藏在潜水船下方。
3. Indeed, the world's 37 species of seahorse are fish, breathing through gills and using a swim bladder to control their buoyancy. 事实上，世界上有37种海马是鱼，它们通过鳃呼吸，用鱼鳔来控制浮力。
4. On land, the supportive buoyancy of water is missing, the plant is no longer bathed in a nutrient solution, and air tends to dry things out. 在陆地上，水的浮力支持消失了，植物不再浸泡在营养液中，空气会使植物变干。
5. The likelihood is that the slump will be followed by a period of buoyancy. 有可能在衰退之后出现一段繁荣时期。
