The response may change the fate of the turions in the second year,and affect the maintenance of the populations.

在野外池塘中，利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响，结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应，在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上；根、茎、叶和石芽各构件都具有异速生长现象，并且表现规律不一样；菹草的根冠比随底质营养盐的不同而变化；随着营养条件对菹草生长胁迫加重，根、冠的异速生长愈明显，同时石芽的N∶P和C∶N比率显著受底质营养盐的影响，而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响，这些响应将改变石芽第2年的命运和影响种群的维持；在胁迫生境下，菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续，以回避策略应对底质营养盐胁迫。

At the end of 1970's, people were liberated from the crevice of the Political Revolution. With the transformation of socialism ideology system, the market economy developed quickly. The government hoped that goods stimulating could offset the people creasy to the political revolution and the nihility of the nation.

70年代末把人从疯狂的政治革命夹缝中解脱出来，随着国家社会主义意识形态体制的转变，市场经济的发展迅速，政府机制希望通过物质刺激来抵消人民对政治革命的狂热性和民族的虚无性，人们自我意识的苏醒，在思想上反思以及生活中越来越强调个性的魅力和才智，人越来越独立自身的生存习性和认识事物的价值体系，在相互倾扎的同时人作为本身已经不存在。

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。
