So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

通过大田条件下旱地高产小麦耗水规律及产量变化的研究表明，4个品种耗水量、产量、水分生产率、籽粒产量中来自花后光合器官输送的比例及综合效益评判结果均以鲁麦21和莱农9217为高，而莱农8834和烟D27则与此相反，因而在旱地高产麦田应以种植鲁麦21和莱农9217为主，中产麦田以莱农8834和烟D27为主，以获得高产高效。2在旱地高产大田对鲁麦21与烟D27两品种花后旗叶、根系衰老及产量变化进行了研究，认为花后旗叶与根系SOD、CAT活性、可溶性蛋白质含量、i-PAs含量及籽粒iPAs含量降低缓慢，MDA含量、ABA含量及籽粒ABA含量增加缓慢，同时保持较高的根系活力且下降缓慢，有利于延缓衰老，形成高产。3土层厚度对旱地小麦花后衰老、氮素分配利用及产量的影响进行了研究，随土层厚度加深，根系活力、根系与旗叶SOD、CAT活性及可溶性蛋白质含量增加，MDA含量减少，土层愈薄，其根系与旗叶衰老愈快。

Determine the content of the moisture with the dry law of the atmosphere; With is it draw law draw fat , analyse the backbone fat first esterification with the gaseous phase chromatogram to ask for; Determine the content of starch by fastenning all law; Propose the alcohol and sink the law and draw many candies with water, and determine many content of candy more than the color law with the phenol - the sulphuric acid.

用常压干燥法测定水分含量；用索氏提取法提取脂肪，将脂肪甲酯化，用气相色谱分析主要成分；用旋光法测定淀粉含量；用水提醇沉法提取多糖，并用苯酚-硫酸比色法测定多糖含量。

Both oils, light oil or solid oils or varnish, often referred to as drying or curing process of drying rate are light oil itself essulenta, filming conditions, including temperature, humidity, film thickness, etc and the finishing of the packaging business card printing and membership card making products material especially moisture how much nature of accountants.

无论底油、光油还是固体底油或光油，常被称为干燥或固化的过程的干燥速度都是由光油本身组成结构、成膜的条件（包括温度、湿度、油膜厚度等）和被涂饰的包装制卡和会员卡制作制品的材质尤其是水分会计师多少特性决定的。

Their water use efficiency exceed that of duplation clone under drought stress, which show that tetraploid clones have more yield at the same irrigation.

两个四倍体品种的水分利用效率无论在哪种干旱处理方式下都显著优于二倍体，说明在同等供水条件下，四倍体品种有较大的生物量产出。

Rising global temperatures threaten not only to flood the homes of America's coastal liberals but also to turn large swathes of the grain-producing heartland into a dustbowl, according to the most alarming predictions.

最令人担忧的预测显示，持续上升的全球气温不仅可能淹没美国沿海自由派人士的家园，还会将大片产粮的中部地带变成水分奇缺的干涸之地。

Due to the complexity of the interaction between electromagnetic wave and the earth's surface, especially in the district covered vegetation, vegetation canopy disturbed strongly radar backscatter coefficient. So it is difficult to monitor soil moisture.

由于电磁波与地表相互作用的复杂性，特别在植被覆盖地表区域，雷达后向散射系数会受到植被覆盖层的强烈影响，这给监测土壤水分带来了极大的困难。

The important reason for ecological degradation in northern farming-pastoral ecotone is unreasonable and too intensive utilization of field water.

不合理的土地利用方式与利用强度导致农业用水不合理是造成北方农牧交错带生态退化的重要原因，适度开发利用农田水分是当前发展农业生产和重建生态系统的关键。

Because of natural and human factors, the Wall paintings of Mogao grottoes are deteriorated by efflorescence, detachment, flaking and many other serious diseases.

目前对于崖体中的盐分和水分的分布现状还没有一个很深入的研究，这对于具体分析壁画病害产生的根源显得非常不足。

The split between the two groups can hardly be papered over.
