原因的说明

Linear regression analysis showed that the product of Freundlich adsorption constants, Kf(1/n), had a positive correlation with 1/Sw and/Sw, showing that the adsorption of acetanilide herbicides on soil was mainly controlled by the content of soil organic matter and the solubility of herbicides.

四种酰胺类除草剂的 Freundlich 吸附常数 Kf(1/n)与1/Sw 、/Sw 有很好的线性相关性，这说明它们在土壤中的吸附主要受土壤有机质含量控制；分子中酰胺 N 的醚取代基的结构差异造成的溶解度差别，是导致不同酰胺类除草剂在土壤上吸附差别的主要原因。

The large distribution of conjugation length was regarded as the reason of vanishing of the vibronic structure. Low costing MeO-PPV was prepared via modified Burn's method.

发现三种方法合成的前驱聚合物在转化初期有相同的PL光谱变化，说明这些前驱聚合物的共轭结构增长过程是相似的，并推测共轭长度分布宽是振动结构消失的原因。

Therefore the RMB appreciation is helpful for balancing China international balance of payment step by step, but the reason lead to the China international balance of payment surplus is profundity and complex especially to the cumulation of trade surplus, which is no only lead by undervalued RMB and improper form system of RMB exchange rate.

这说明虽然人民币升值有利于促进我国国际收支逐步趋于平衡，但是我国的国际收支顺差，尤其贸易顺差的累积&冰冻三尺，非一日之寒&，有着深刻、复杂的原因，不单单是由于人民币被低估或者人民币汇率形成机制不合理造成的。

Prolonged intake of melamine will damage animal reproduction and urinary systems, bladder/renal stones will further induce bladder cancer.1994 International Programme on Chemical Safety and European Commission coedited International Chemical Safety Manual Vol.3 and International Chemical Safety Cards specify that:: prolonged or repeated intake of melamine might influence kidney and bladder, giving rise to stones. The preliminary investigation of 2007 America pet food contamination incident regards that wheat protein powder doped with ≤6.6%%melamine is the cause of pet food poisoning.

动物长期摄入三聚氰胺会造成生殖、泌尿系统的损害，膀胱、肾部结石，并可进一步诱发膀胱癌。1994年国际化学品安全规划署和欧洲联盟委员会合编的《国际化学品安全手册》第三卷和国际化学品安全卡片说明：长期或反复大量摄入三聚氰胺可能对肾与膀胱产生影响，导致产生结石。2007年美国宠物食品污染事件的初步调查结果认为：掺杂了≤6.6%%三聚氰胺的小麦蛋白粉是宠物食品导致中毒的原因。

Female Tigons and Female Ligers both possess a tiger X chromosme and a lion X chromosome, yet only the female Ligers will grow large, this means something must happen to either alter the genes or that the cause of the growth dysplasia lies at least partially outside of the genes.

雌虎狮兽和雌狮虎兽都有一个老虎的X染色体和一个狮子的X染色体，但是只有雌狮虎兽会长成庞然大物，这说明一定有什么事情发生了，改变了每一方的基因，或者狮虎兽的生长异常有基因之外的某些原因。

It suggested that tea processing had great influence on formation of tea volatiles and it is possible to improve tea flavour by improved processing techniques.

说明不同茶类加工工艺的差异是导致香气成分差异的重要原因，该结果为通过加工技术的改进达到改善茶叶香气提供了充分的依据。

And the small birds they were singing,i carelessly did stray,the thrushes they were warbling,to view fond lovers talking,a while i did delay.she said, my dear don't leave meall for another season

解释，就是在观察的基础上进行思考，合理地说明事物变化的原因，事物之间的联系，或这是事物发展的规律。

4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。

During the experiment, we choose Toyota Corona 1600cc as a test car and measure its maximal acceleration value by means of palm vibration noise analyzer, on conditions of the same tire pressure, speed, load, and road section and measure fuel consumption in a fixed speed and mileage. In addition, by using tire pressure gauge and infrared thermometer, measure after-driving tire pressure and tire temperature to make a comparative analysis. Finally, we use 185/60 R-14 Goodyear tire to measure tire sinkage in an empty car and a loaded car and obtain tire compression ratio to explain the difference of riding comfort and economical consideration of fuel consumption between nitrogen-filled tires and compressed air tires.

在实验时，采用丰田Corona 1600cc轿车，在相同的胎压、车速、负载、路段等条件下，透过掌上型振动噪音分析仪，撷取车辆行驶之最大峰值加速度；并在稳定车速及固定里程下量测汽油之消耗量，再以胎压表和红外线温度计，量取行驶后之胎压和胎温值来作比较分析，最后，再使用185/60 R-14 Goodyear 轮胎，在车上量测空车及负载下轮胎的下沉量，并求得轮胎的压缩率变化值，来说明氮气轮胎与一般压缩空气轮胎，在乘坐舒适性及燃油经济性上的差异原因。

What we are going to discuss involves not only sound cycle in chain shift,but the re-appearance of phonetic phenomenon caused by a variety of reasons.This thesis gives a definition of cycle phenomenon anew and synthesizes more materials to illustrate this topic in every aspect, especially to illustrate the sound cycle led to by other factors except chain shifts.

本文对循环现象重新定义，并综合更多语音演变的材料对这一问题中各方面的情况，特别是对非链移方式导致的循环现象加以说明，试图找出变化的原因，发现循环对于研究语言发展的价值。

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。
