Some, perhaps, may simply be intercepting water for one user that would otherwise have gone to another, but almost every country could reduce its evaporation losses by capturing water and delivering it more effectively to the farmer, bather, drinker or manufacturer—and then, ideally, using it again.

有些国家也许只是出于自私的目的将水拦截，不让水流向其他国家，但几乎每一个国家都可以通过集水和提高输水效率的办法减少水的蒸发损失，使水能够高效地用于灌溉、洗浴、饮用及制造产品，更理想的是，能够循环利用这些水资源。

The garden??s characteristic is "the north catalpa plants in south and the south flower open in north", you can find the beverage bottle coconut tree, Canada tropical plants, betel nut and other tropical plant here. Meanwhile, you may understand the irrigation facility which introduces from Israel - micro spurts, the domestic origination vertical column type cultivation technology and other advanced scientific agricultural knowledge, it is undoubted that double income we have got, viewing beautiful scene and increase our knowledge!

观光园的特色是"南树北栽，南花北开"，在这里可以看到酒瓶椰子、加拿利海枣、假槟榔等热带植物，还可以了解到从以色列引进的灌溉设施－微喷、国内首创的立柱式栽培技术等先进的科学农业知识，真是观美景、长见识，双收益！

The selection of N-catch crop and the capacity of nitrate extraction from deep soil layer by catch crop were reviewed in the paper. It also pointed out that combining with N-catch crop in the rotation system had been regarded as a good approach for safe vegetable production.

过量施用的氮肥在自然降水或灌溉水的作用下，可通过径流损失造成地表水水体的富营养化；部分土壤中的NO-3 N可随水向下迁移污染地下水，在地下水环境中仍主要以硝态氮形式

This paper studies the main geometrical parameter such as angle, height, width, stagger and the upper width in dentation and trapezoid flow path, firstly, uses the single-phase numerical simulation of the computational fluid dynamics technique to analyse the influence of different geometrical parameter on discharge coefficient and flow state exponent of drip emitter. Secondly, uses the two-phases numerical simulation of CFD (1% sand content ) to analyse the influence of the above mentioned geometrical parameter on the contribution regulation of sand and anti-clogging performance. Thirdly, uses the PIV （ particle Tracking Velocimetry ） technique which can see the small-scale flow path to observe and test the trajectories and velocities of solid particles in labyrinth flow path, and analyses the basic factors which can influence the movement characteristic of solid particles and the flow state in flow path.

本文以齿形流道、梯形流道为主要研究对象，以流道转角、流道高，流道宽、偏差量及梯形流道上底宽为主要结构参数，首先应用 CFD 单相流数值模拟技术对不同结构参数灌水器流道水力性能进行模拟，分析了不同结构参数对流态指数和流量系数的影响，其次，应用 CFD 两相流（含沙量为1%）数值模拟技术分析了结构参数对含沙量分布规律和抗堵塞性能的影响，然后，应用 PIV 可视化测试方法测试了固体颗粒在流道内运行轨迹及速度，分析了影响固体颗粒运动特性及流道内流体流态的基本因素，最后，对上述流道结构形式通过模具加工及滴灌带试制，进行了标准化测试（ GB/T 17187-1997 农业灌溉设备滴头技术规范和试验方法与 ISO 标准 ISO /TC23 /SC18 /WG5N4短周期堵塞测试程序），测试结果验证了 CFD 模拟结果，并提出了迷宫结构流道灌水器的抗堵塞设计方法。

However, use what liquid waste serves as crop to irrigate to already carried out a paragraph of very long time in certain place, it is first-rate example namely in area of Parisian week exclosure for example.

然而，利用废水作为农作物的灌溉已在某些地方实施一段很长的时间了，例如在巴黎周围地区即为最佳的例子。直至1940年，在巴黎周围地区处置废水的惟一方式即作为市

Shortage of water, pollution of tributary waters and incretion of sewage irrigation for farmland make the potentiality impact on environment and safety of agricultural products.

适当处理的城镇生活污水是一种稳定的水资源、在很大程度上缓解水资源的紧缺状况，利用污水资源的主要用途之一是灌溉农田。

From the bank of an irrigation canal, Shen gazes over the green expanse and marvels at the river's power:"I always thought this was the most beautiful place under heaven."

现在他站在灌溉水渠的堤岸上，凝视着面前大片的绿色，感叹着黄河的神奇："我总是认为这是世界上最美丽的景色"。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
