buoyance
- 1. Salt water has more buoyance than fresh water.
- 咸水比淡水浮力大。

- 2. Use a heavier rope to fasten an inflated balloon, heavier enough to resist the buoyance of the balloon in order to keep it still in the air.
- 用粗一些的绳子绑住气球，减掉一段使剩余的绳子重量刚好能够承载气球的上升力，以达到气球稳定漂浮在空中。

- 3. The driving force of primary migration is mainly abnormal high pressure and that of secondary migration is buoyance and fluid potential difference.
- 初次运移的动力主要是异常高压，二次运移的动力主要是浮力和流体势差。
