通过实验研究莫尔吸量管吸入部分热水的热水喷泉现象，并自行设计实验装置避免人手扳动时抖动莫尔吸量管， 从而形成连续水柱. 根据范德瓦耳斯方程结合伯努利方程对喷泉喷射高度进行了理论推导和数值计算，通过多项式拟合方法 来解决喷泉传热温度不易测量的问题，再探究多种实验参数对喷射高度的影响. 根据实验结果: 喷射高度与温度成正比; 吸水 量约为莫尔吸量管的30% ～ 45%，喷嘴的直径越小，热水喷泉的喷射高度越高.

The fountain phenomena of a Mohr pipette with partially filled hot water through experiment are investigated. We design an improvement of device to avoid people throw shake Mohr pipette，forming a continuous water column，so the theoretical deduction and numerical calculation of fountains’jetting height are combined with Van der Walls equation and Bernoulli equation. We use the polynomial method to research a variety of experimental parameters and to avoid human factor due to heat transfer temperature is not easy to measure. We get the experimental results: the injection height of the hot water fountain is proportional to the temperature， the smaller the diameter of the nozzle is，the higher injection height of the hot water fountain when the absorbent amount is about 30% ～ 45% of pipette.
