分析了在三种不同的物理环境中发生的轴对称悬垂液滴：具有恒定压力和固定圆形开口（虹吸管）的问题A;具有恒定体积和固定圆形开口（药物滴管）的问题B;以及具有规定体积和与水平板接触的恒定角度的问题C。作为实例，对结果进行了验证。对于问题B，表明如果开口足够小以支撑具有凸起的稳定悬垂液滴，则随着暴露体积的增加，将形成具有颈部和凸起的稳定悬垂液滴。对于问题C，它示出，随着体积的增加，稳定的悬垂液滴的家庭的轮廓曲线将发展不稳定出现之前的拐点。
The axially symmetric pendent drop as it occurs in three different physical settings is analyzed: Problem A with constant pressure and a fixed circular opening (the siphon); Problem B with constant volume and a fixed circular opening (the medicine dropper); and Problem C with prescribed volume and a constant angle of contact with a horizontal plate. As examples, the results are verified. For Problem B it is shown that if the opening is small enough to support a stable pendent drop with a bulge, then as the exposed volume is increased, stable pendent drops with both a neck and a bulge will be formed. For Problem C it is shown that with increasing volume the profile curves for the family of stable pendent drops will develop an inflection point before instability arises.
