贫瘠的

If the project is successful, barren stretches of land in Oman may be exploited agriculturally.

如果实验成功，阿曼的贫瘠土地就可以加以利用。

The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro-algae , soil pH value , soil organic matter soil available phosphorus and soil nitrogen.And then, the author put fertile soil, which included micro-algae, proportionally into sterile samples and cultivated them respectively under illumination condition (micro-algae can live and reproduce)and dark condition(micro-algae will die in some time).The above indices were measured in 0, 30, 60 and 90days respectively, The analyse of the interrelation between the change of micro-algae"s number and the changes of soil pH value, soil organic matter, soil available phosphorus and soil nitrogen indicated:Soil micro-algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro-algae.Under dark condition,the micro-algae"s number declined gradually and went to zero in the end,while under illumination condition ,on the 90th day, the micro-algaes number of per gramme was 6-7 times more than that of the beginning.

本文首先对肥沃土壤与经高温焚烧后的贫瘠土壤中的微藻数量、土壤pH值、有机质含量、有效磷含量和全氮量进行比较研究，然后将包含微藻的绿化苗圃地肥土按不同比例接种进入贫瘠土样中，分别在光照条件和黑暗条件下进行培养，在0天、30天、60天和90天分别检测以上指标，比较有光条件和无光条件下，即有藻条件和无藻条件下贫瘠土样所发生的变化，并分别对微藻数量的变化与土壤pH值、有机质含量、有效磷含量和全氮量的变化之间做相关性分析，以评估肥沃土壤中的微藻接种进入贫瘠土壤后的生长情况以及对贫瘠土壤的改良作用。

Now stand you on the top of happy hours, And many maiden gardens, yet unset, With virtuous wish would bear your living flowers, Much liker than your painted counterfeit: So should the lines of life that life repair Which this time's pencil or my pupil pen, Neither in inward worth nor outward fair Can make you live yourself in eyes of men.

这一刻，让我不能停止对你勇敢的进攻就如一个血腥暴君战争的猛烈直到你渐渐的平息那些快乐胜过了我贫瘠的诗韵现在你站在幸福时光的顶峰就如少女般笑楹的曾经你活了花开的圣洁酷似争艳的爱的灵魂那生命轮线的修饰我用了铅笔着墨外在的喜悦无法掩饰内心的兴奋你在我眼神里活回自己永远活力青春弥漫甜蜜芳醇

By the cluster analysis, 10 grasses were classified into three types—of high barren resistance: Bromus inermis,Festuca arundinacea, Dactylis glomerata; of medium barren resistance: Bromus biebersteinii,Phleum pratense,Phalaris arundinacea; of low barren resistance: Festuca rubra, Agropyron desertorum,Agropyron smithii,Elytrigia elongate.

对10种牧草进行聚类分析，得出耐贫瘠性强的是无芒雀麦、苇状羊茅、鸭茅；耐贫瘠性中等的是草地雀麦、猫尾草、草芦；耐贫瘠性最弱的是紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草。

In order to select a kind of eminent grass which is adaptable to the northern China, the present thesis studies ten kinds of grasses from Gramineae, Bromus biebersteinii,Bromus inermis,Festuca arundinacea ,Festuca rubra,Dactylis glomerata ,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea,and also explores the physiological aspects of their drought resistance, cold tolerance and barren resistance. The drought resistance experiment was conducted to study 10 grasses under water stress during seedling stage by simulating indoor drought environment.

为了能选适应我国北方地区的抗旱、耐寒、耐贫瘠特性的优良牧草，本研究以草地雀麦、无芒雀麦、苇状羊茅、紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草、猫尾草、鸭茅、草芦为材料，在抗旱、耐寒和耐贫瘠性特性三方面的生理方面进行了探索研究。

The energy consumption in unit architectural area in our country is nearly 4 times as much as that in developed country with the approximate climatic conditions. China is a country with deficient energy resources, so using the energy reasonably and enhancing the utilization ratio are fundamental plans for developing our society. Improving the energy conservation technology for exterior wall and enclosure structure, innovating the heat insulation materials, and reducing building energy consumption are of great significances.

当今社会，发达国家都空前地重视节能问题，我国目前的单位建筑面积采暖用能耗相当于气候条件相近的发达国家的3～4倍，中国是一个能源比较贫瘠的国家，因此合理利用能源，提高能源利用率是我国社会发展的根本大计，而建筑物外墙围护结构节能技术的改进，保温材料的更新对社会及建筑能耗的降低具有极其重大的意义。

The reason included five aspects:①the effect of physical environment: the open geographical environment and barren soil urge the Greeks to look for development outward while the close geographical environment and advantaged condition for agriculture shaped the Chinese conservative thought and obstructed their steps of going out.②the advancing and blocking of the economic: the frequent trade offered an abundant living supply and open view while the self-sufficient agriculture with restraining trade rigidified the thought.③ the difference in politic institute and situation: the democracy polis of ancient Greece is exclusive in the ancient world. It shaped the atmosphere of freedom, democracy and adversary. While the monarchy in ancient China pursued the "united country" and shaped the atmosphere serving for politic and consolidating thoughts.④the guiding of traditional culture: the Greeks pursued freedom and wisdom and were curious about nature while the Chinese adored ancestor and obeyed the authority and prefer to pragmatism.

出现这种关系的原因本文从以下五点进行分析：①自然环境的影响：古希腊开放的地理环境和贫瘠的土壤种植条件促使古希腊人向外寻求发展，而古代中国封闭的地理环境和优越的农业环境阻碍了中华民族外出的脚步和开放的思维；②经济条件的推动与束缚：工商业发展的农业经济和自给自足的小农经济所创造的物质条件和对思维影响的差别是很大的；③政治制度和政治形势的差异：古希腊民主城邦制在古代世界是独树一帜的，它所营造的自由、民主的氛围和古代中国追求&大一统&的君主专制下为政治服务、思想趋向统一的氛围截然不同；④传统文化的引导：古希腊人在长期的城邦生活和参与海外贸易的生活中形成的开放、自由、对自然充满好奇、追求智慧等民族文化传统与中国保守崇古、讲究实用的文化传统形成了鲜明的对比；⑤思想家本身(来源：A58BC论文网www.abclunwen.com)目的不同：古希腊思想家为了变得智慧而获取知识，享受知识带来的乐趣，而古代中国思想家的一切动机都是为了&成化天下&、&以政裕民&服务。

The native grasses and weeds, the scattered patches of gorse, contended with one another for the possession of the scanty surface soil; they fought against the droughts of summer, the frosts of winter, and the furious gales which swept with unbroken force, now from the Atlantic, and now from the North Sea, at all times of the year; they filled up, as they might, the gaps made in their ranks by all sorts of underground and overground animal ravagers.

土生土长的莽原莠草，散布遍生的金雀花丛，竞相占据那贫瘠的表层土壤。它们与盛夏的烈日骄阳作斗争，同隆冬的严霜沆砀相抗衡，直面从大西洋或北海不断扑来的疾风，四时代序，从未停歇。它们极尽可能地成列生长，以弥补天地生灵遗留的空隙。

Colorful garden of colorful, light spring green spring vegetable bed, jade-like transparent, Doo-Yan flowers, blooming race, cold wind and opened the Happy蜂蝶; calm sea, fishes fish salty gash of the wind waves,水灵like precious stones, rough waves, one after the other, petrels soar down in the storm clouds; sparsely populated desert, the scorching sun baked the shortage of barren rock, hell dead, Cheng Wang snow from cold water, flowing babble, Ganquan started Oasis of the curtain.

花园里五彩斑斓，融融春光照亮碧绿的菜畦，翡翠般透明，斗艳的鲜花，竞相绽放，泠风吹开蜂蝶的逍遥；大海上风平浪静，丝丝咸风划开鱼儿的波浪，宝石般水灵，汹涌的巨浪，前赴后继，海燕翱翔在乌云压低的暴风雨中；沙漠中人烟稀少，炎炎烈日炙烤着贫瘠的荒石，地狱般死寂，琤王从的雪凉水，潺潺流淌，甘泉拉开绿洲的帷幕。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
