| 摘 要： | 通过理论分析，建立了气体溶解方程，导出了适用于大洋采矿气力提升的气体溶解公式，它反映了气体溶解度与压力，相对含气率，气泡直径，固体颗粒比重和浓度诸因素的关系，分析表明，在洋面以下２０００ｍ深处，空气溶解度为大气压，同温度条件下的溶解度的１５～８０倍；由于空气溶解，将导致气力提升效率降低１５％～２５％左右。

| Abstract: | By theoretical analysis, the air solubility formulae that are suitable for calculation of air-lift for ocean mining are established. This reflects the relationship between air solubility and pressure, relative rate of air content, diameter of air bubble, specific gravity and density of solid particle. It is shown ,at the depth of 2000m below the sealevel, that the air solubility is 15-80 times as much as that at the sea level under the same temperature condition. As a result of air dissolving, the efficiency of air lift decreases by 15%-25%. |
