1. Salt water has more buoyance than fresh water.

2. Factors that could dampen the market's buoyance and reverse its direction are weak consumer sentiment and a lack of spending.

3. The buoyance of underground structure in a high ground water level area is a problem needing solution, so the anti-pullout mechanism of underground structure has become an important research topic.

4. Based on the experiment of sand and clay, the computing method of buoyance without seepage is analyzed.

5. 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.

6. In this paper, three types of nonlinear liquid systems (NLS) are introduced, which are the exchange, buoyance and loading types. In fact, they are variable mass systems.

7. The driving force of primary migration is mainly abnormal high pressure and that of secondary migration is buoyance and fluid potential difference.
