A VOF method was developed to simulate the burst of a axisymmetric buoyancy bubble near a free surface, the formation, rise and descent of a liquid column after the burst, and the whole course of the oscillation of the free surface occurring afterwards until the free surface tends to calm.

发展了一种VOF方法，用以模拟自由面近旁单个轴对称浮力气泡的破裂、破裂后液柱的形成、上升和下降、以及随后发生的液面振荡直至自由面趋于静止的全过程。

The Apollotm float tank is a light-proof, sound-insulated capsule which contains a shallow 30 cm pool of 25% saturated Epsom Salts solution - five times denser and more buoyant than sea water.

apolloTM浮悬箱是一款隔光隔音的容器，里面是一个装有30厘米浅，浓度为25%硫酸镁溶液的水池，溶液的密度和浮力是海水的五倍。

According to previous experimental data, it is found that the buoyancy and capillary force are effected by reservoir temperature and pressure, and the boundary height of natural gas coming-up so on.

根据前人的实验数据，通过理论计算发现，浮力和毛细管力均受地层温度和压力的影响，气体在储层中上浮的临界高度随地层温度和压力的降低而增大。

The released heat can be used by climbers, divers; also can calorify the mechanical and canned food in jumping-offs or cold districts.
