摘　　要：通过对盐水-水小孔周期性泄流的实验研究,对孔径为1.32 mm的8种不同孔长进行测量,得出周期正比于孔长的1.1±0.1次方,同时对孔径为1.32 mm孔长为113.00 mm条件下的内筒液面跟踪记录得出实验曲线为指数形式,与理论分析符合得较好.Through the experimental research of the brine-the water eyelet periodic aerial drainage and the measure of the length of 8 different holes which is 1.32 mm aperture, we obtain the cycle in proportion to the length of the hole 1.1 ±0.1 powers of exponent. At the same time, we track the record of the inner tube liquid level which has 1.32 mm aperture and 113.00 mm length to get the experimental curve which is the exponential form, this is in good agreement with the theoretical analysis.
