利用示踪粒子获得直径为２ｍｍ的环状铂金坩埚内Ｌｉ_２Ｂ_４Ｏ_７＋ＫＮｂＯ_３熔体近坩埚区域的表面张力对流速度场；并从理论上推导出表面张力对流速度场解析表达式，推导结果与实测结果一致．

Na₂CO₃ particles were utilized to trace the thermocapillary convection of Li₂B₄O₇+ KNbO₃ melt in a loop--like crucible. The thermocapillary convection velocity field beside the crucible inner edge was experimentally measured. From thermodynamic equation this velocity field was also obtained theoretically and it confirmed with the experimental data exactly.
