灌溉

According to the basic theory of market ecoomics and micro-economics,the marktstyle of irrigation sector has been identified as unperfected nature monopolize market,withthe characteristic of the same water being saled to different markets by irrigation waterprovider.

运用市场经济理论和微观经济学的基本原理，分析了灌溉水市场的基本特征，确定灌溉水市场为厂商向不同市场销售同一产品的限制性自然垄断市场。

The premises of the simulation are that the runoff from upreach is 7.8× 108m3/a and the means of economization on water is in effect. When studied it was thought firstly the water for the lake area and the living plant of the oasis, then for forest-sod irrigation and farmland irrigation.

模拟计算是以上游下泄水量7.8×10~8m~3／a为前提条件，在实行节水措施，完善供水系统的情况下，首先满足维持和恢复一定规模湖泊面积，保证绿洲植被正常生长所需水量，然后考虑林草灌溉用水和农田灌溉用水量。

This paper pointed out many disadvantages of our now experience-based irrigation. The author deeply studied the decision support system of irrigation of the cucumber and romaine lettuce based on the transpiration rate and greenhouse environment factors —temperature, humidity and light.

本论文针对目前国内大多数温室采用传统的经验法进行灌溉存在的弊端，以黄瓜和生菜为研究对象，对以温度、湿度和光照强度等温室环境因子以及蒸腾速率为依据决策灌溉量进行了较为深入的研究。

Part II: In accordance with the meaning of Zhuang toponomys, summed up several factors strong associated with the spatial distribution of the Zhuang toponomy,including the altitude, distance to the central cities, and distance to traffic line, whether in the land of paddy soil or irrigation area, the slope and aspect.

第二部分：根据壮语地名的涵义，总结出了海拔高度，与中心城市距离，与交通线距离，是否靠近或在灌溉用地或水稻土范围内、山体坡度、坡向几个与壮语地名的空间分布存在相关性的因子，经过统计分析发现壮语地名和非壮语地名相比较而言在空间分布上具有这样的特点：聚居地海拔高，与中心城市距离远，拥有灌溉耕地的机会多，距离铁路近。

The results of saline water irrigation (1990~1995) showed that the yields of wheat, corn, cotton and grain increased 30% more than those of non-irrigated crops. In the condition of spring irrigation and concentrated rainfall, the soil desalinized in root zone, and the accumulated salt due to saline water irrigation can be leached; reasonab...

三坝浅层地下咸水灌溉试验( 1 990～ 1 995)的研究结果表明，利用 3.0～ 5.1 g/ l的咸水灌溉小麦、玉米、棉花和高粱，均比不灌的增产 30 %以上；在春季河灌和汛期集中降雨淋洗的条件下，作物根层土壤不积盐；实行咸淡水轮灌，增辟水源，改善水质，可获作物增产。

In abandoned land and peripheral desert of oasis, influenced by irrigation of oasis, groundwater table has been raised above the critical depth.Because the soil salt cannot be eluviated by irrigation water and precipitation, salt brought to the upper layers of soils by strong evaporation is especially concentrated on soil surface.

绿洲内的撂荒地和靠近绿洲的荒漠草地受绿洲内部灌溉过程的影响，地下水位升高，超过了地下水的临界深度，同时又因为缺少灌溉的反复淋洗，在强烈的蒸发作用下，盐分的表聚现象十分明显，而且整个剖面内盐分的含量都较高，土壤的盐渍化现象非常严重。

Wild flooding is inefficient in use of water and labor, but it irrigates land that can't be managed by other methods of surface irrigation.

漫灌的用水效率和劳动效率都是很低的，但它能用来灌溉那些不能采用其他地面灌水方法灌溉的土地。

On this basis, I adopt the two-dimentional dynamic planning principle to optimize the irrigating system of the cotton.

推求了棉花的经济灌溉定额，为棉花灌溉制度的制定提供了科学的依据。

Glenn noted the water that percolates out from normally irrigated soil , technically known as irrigation return flow , is often as salty as 10 percent seawater.

格伦指出，从灌溉的土壤中渗流出的水在学术上叫做灌溉回归水，这种水的含盐量通常是海水的百分之十。

The practices of efficient use of water were studied and popularized at the same period.

在扩大灌溉面积的同时，研究和推广了以节水为中心的灌溉新技术。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
