摘　　要：根据液体表面函数最低原理,证明液体表面气泡在足够大时呈半球状,在气泡稳定后,液膜收缩压与气泡球面曲率半径成反比,据此可以利用半泡法测量液体表面张力系数.According to the principle of the minimum liquid surface function,the bubble was hemispherical and large enough,after the bubble comes stable,the bubble film of systolic blood pressure is inversely proportional to the radius of spherical curvature,which can use the semi global method of measuring surface tension coefficient of liquid.

关 键 词：液体表面张力系数 半泡法 函数最低原理
