In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

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。

The phosphorus removal experiment implies the increasing 100 mg/L MLSS concentrations can remove about 1 mg/L TP. The phosphorus removal efficiency can be improved by the increasing rate of MLSS concentrations. When everyday increasing rate of MLSS concentrations are about 500mg/L, the phosphorus removal efficiency would higher than 90%, effluent TP would be lower than 1 mg/L. When MLSS concentrations are fluctuating, effluent phosphorus would fluctuate correspondingly. Everyday the amount of discharging excess sludge can be prejudged by the amount of influent TP.

通过对反应器的除磷效果的研究，发现污泥浓度增长100 mg／L能去除将近1 mg／L TP；发现随着污泥浓度增长速率的增加，除磷效率相应提高；当污泥浓度的增长速率增加到每天500 mg／L时，磷的去除率将高于90％，并且出水TP浓度将低于1 mg／L；发现每天排放的剩余污泥量可以根据进水TP浓度来决定；发现最佳好氧与厌氧时间比T_是0.5；溶解氧冲击指数DO_I被首次提出，作为分析溶解氧DO影响的指标。

This study was protocoled to attach both harden circle-frame with filter-rods and much smaller mesh of outer codend to the anterior of traditional codend for measuring the escape rate. Three intervals were introduced as 17mm, 19mm, and 21mm between the filter-rods in this study. In addition, the running-water tank was used to examine the survival rate of escaped fish in the experimental codend.
