A hotwire anemometer was used to measure the jet velocity at the exit of the precessing jet nozzle and the power spectrum density was obtained afterwards in order to analyze the precessing feature of the jet. It is shown that an obvious precession motion is generated in a nozzle even with a large expansion ratio E=10 and a small length-to-diameter ratio LD=2. The precessing frequency is mainly dependent on the nozzle diameter and the intake flow rate, increasing with the enhancement of the flow rate and with the reduction of nozzle diameter.

采用热线风速仪测量旋进喷嘴出口射流的速度，并对该射流进行功率谱分析以研究其旋进特性，结果表明，实验所用的膨胀比E=10、长径比L/D=2的喷嘴同样能产生明显的旋进射流，旋进频率主要取决于喷嘴的尺寸和射流的流速，并随流速的增大和喷嘴直径的减小而增大。

In 1 irrigation time and 2 irrigation times treatments, soil salt content decreased by 11.7%, and soil salt content increased by 12.6% in 3-4 irrigation times treatments. 2 After irrigation, the mean reduction of soil bulk density was 6.5%, and the mean increment of soil total porosity was 18.1%. With the irrigation frequency increasing, soil density was decreased and soil total porosity was increased. 3 Soil infiltration course of reed field irrigated by wastewater fitted Horton infiltration model well. After wastewater irrigation, the first infiltration rate decreased, but the stable infiltration rate promoted with the wastewater irrigation frequency increasing. 4 Soil water-holding capacity was increased by wastewater irrigation. The maximum water-holding capacity in capillary was 90.15 mm in the treatment of irrigation 3 irrigations, and the maximum water-holding capacity in non-capillary was 4.15 mm in treatment of 4 irrigations.

废水灌溉后，土壤pH均值降低6.0%；废水灌溉1～2次，土壤含盐率降低11.7%，废水灌溉3～4次后，增壤含盐率增加12.6%。2）废水灌溉后土壤体积质量均值减小6.5%，总孔隙度均值增大18.1%；随着废水灌溉次数的增多，土壤体积质量和总孔隙度分别有减小和增大的趋势。3）Horton模型比较适合描述废水灌溉后芦苇群落的土壤入渗过程，废水灌溉降低了初渗率，但随着废水灌溉次数的增多，稳渗率增加明显。4）废水灌溉增强了土壤贮蓄水分的能力，废水灌溉3次吸持贮水量达到最高（90.15 mm），灌水4次滞留贮水量达到最高（4.51 mm）。
