Under soil water stress conditions, the photosynthesis rate, water useefficiency and light compensation point of Atriplex canescens obviouslyreduced, and its dark respiration rate weakened. In the treatments in July, theaccumulative and average value of daily Pn from high to low is: light soil water stress＞no soil water stress＞medium soil water stress＞heavy soil water stress, the valueare 7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1) and 1.761μmolm~(-2)s~(-1), respectively. In the treatments in August, the accumulative and average value ofdaily Pn from high to low is: light soil water stress＞medium soil water stress＞heavy soil water stress＞no soil water stress, the value are 7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1) and 1.705μmolm~(-2)s~(-1), respectively.

在土壤水分胁迫下四翅滨藜的净光合速率、水分利用效率、和光补偿点显著降低，暗呼吸速率减弱。7月份各处理Pn全天的累计值和平均值的大小顺序为：轻度土壤水分胁迫＞无土壤水分胁迫＞中度土壤水分胁迫＞重度土壤水分胁迫，它们的值分别为：7.162μmolm~(-2)s~(-1)、6.106μmolm~(-2)s~(-1)、6.103μmolm~(-2)s~(-1)和1.761μmolm~(-2)s~(-1)。8月份各处理的Pn全天累计值和平均值的大小顺序为：轻度土壤水分胁迫＞中度土壤水分胁迫＞重度土壤水分胁迫＞无土壤水分胁迫，它们的值分别为：7.378μmolm~(-2)s~(-1)、4.738μmolm~(-2)s~(-1)、1.794μmolm~(-2)s~(-1)和1.705μmolm~(-2)s~(-1)。9月份四翅滨藜的Pn变化趋势于8月份的变化曲线基本相似，唯一不同的变化就是各个处理的Pn比8月份的要高，这可能于9月份气温降低，湿度增大有关。

Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

通过理论分析和实验研究，本文得出以下结论：高承压水在沿煤层底板隔水层导升过程中存在着明显的压力水头损失；同一地层条件下，煤层底板承压水水头压力越大其导升过程中的水头压力损耗就越大；同一水头压力条件下，地层的渗透性越差其阻水能力越强，水流导升过程中的水头压力损耗也越大；在同一介质中，当初始水头压力不同时，水流在导升过程中水头压力的衰减不同，在同一隔水介质中底板含水层水头压力越大其沿隔水层导升过程中的水头损耗也就越大，水头损耗随底板隔水层水头压力增加而呈递增趋势，另外它们相应的水头衰减速率也呈递增趋势，煤层底板隔
