| 摘 要： | 建立了海伦喷泉的基本物理模型,并推导了水柱最大喷射高度和液面差、出水口直径以及液体密度的关系。实验方面表明,在不考虑温度对实验的影响下,利用控制变量法推导出出水口直径大小、液面差、两侧液体密度对水柱最大高度的影响,结果与理论吻合得很好。

| Abstract: | The basic physical model of Helen fountain is established,and the relationship between the maximum jet height of water column and liquid level difference,outlet diameter and liquid density is derived.The experimental results show that,without considering the influence of temperature on the experiment,the influence of the diameter of outlet,the difference of liquid surface and the density of liquid on the height of water column is derived by using the control variable method.The results are in good agreement with the theory. |
