摘　　要：为了了解水平温度梯度作用下环形浅液池内浮力-热毛细对流的基本特性,采用渐近线方法获得了环形浅液池内浮力-热毛细对流的近似解析解,得到了主流区速度场和温度场的表达式,通过与数值模拟结果的比较表明,所得结果是合理的。In order to understand the nature of buoyancy-thermocapillary convection in a differentially heated thin annular pool,we obtained an approximate analytical solution of the buoyancy-thermocapillary convection in a thin annular pool using asymptotical analysis.Numerical experiments are also carried out to compare with the asymptotic solution.It is found that there is a good agreement between the asymptotical solution and the numerical solution.
