摘 要：
恒定水头供水瓶的弹性构件弹簧竖立在敞口容器和支座之间,该装置通过水体自重与弹簧弹力相互作用使敞口容器内的上液面保持绝对高程不变,使水头保持稳定。在实际应用中,可以在一定限度内自由增减敞口容器内水量,避免了马氏瓶在实验前需要放水以维持水头稳定与实验过程中不能对瓶内水量做任何控制以及该仪器不适于高温环境中使用的弊端,且该仪器可以缩小体积,方便拆装与携带。经计算,该装置系统误差在4%以内。研究提出的恒定水头供水瓶,原理简单,适应性强,可在各种入渗、蒸发实验中用于控制水头高度的恒定,具有广泛的应用前景。

摘 要：
The elastic member for spring constant head bottle erected in open vessels and support between the device by gravity and spring water interaction on the level of open containers to keep the absolute height unchanged,the head remained stable.In practical application,free or open containers of water in a certain extent,to avoid the Markov bottle before the experiment in order to maintain the stability and the need to turn on the water head in the process of the experiment can not do any water in the bottle and the instrument is not suitable for the use of defects in high temperature environment,and the instrument can reduce the volume,convenient disassembly and carrying.The system error is less than 4%.The principle of the constant head water supply bottle is simple and adaptable.It can be used to control the height of water head in various infiltration and evaporation experiments.
