即：(1)人类对地下水的利用随社会生产力水平的提高、农牧业活动范围的扩大而趋于复杂化和多类型化；(2)地下水农业利用的深度和广度与当时生产力水平密切相关，生产力水平的高低是决定黄土高原地区地下水农业利用程度与方式的主导因素。

When the concentration of sulfur dioxide was fixed, the reaction rate increased separately with increasing oxygen content and water vapor content, when oxygen content was 20%, the reaction rate was the highest, while water vapor content was 444μmol/L, there was an optimum value for the photocatalytic degradation rate of heptene.

庚烯的降解速率随着二氧化硫浓度的增加而增加，最终趋于稳定。在二氧化硫浓度一定时，庚烯的反应速率分别随着氧气和水分子含量的增加而不断增大，氧含量为20%时速率最大；水分子含量为444μmol/L时速率最大。

The results showed that soil organic carbon, water-soluble organic carbon and humin decreased gradually. Extracted humic substances presented an increasing trend at first and then decreased. Relative proportion of humic acid in HE decreased at first and then increased during the initial stage of corn stalk decomposition, which indicated that the formed rate of fulvic acid was faster than HA. Then PQ dropped gradually and reached stabilization, which indicated that FA and HA transformed into each other for some time and then reached balance.

研究结果表明：随着培养时间的延长，土壤有机碳、水溶性有机碳、胡敏素逐渐减少，可提取腐殖物质先增加后下降，可提取腐殖物质中胡敏酸的相对比例则在玉米秸秆分解初期表现为先减少后增加、最后趋于稳定，表明富里酸和HA经历了一段相互转化的过程后达到了动态平衡。

The study on the electrical property shows that its dielectric property decreases with the slowly increase of frequency in dry state; in hygrometric state (52.9%), the dielectric property grows obviously and declines swiftly with the increase of frequency; and it tends to be stable when the frequency is over 10^4Hz. The specific resistance decreases linearly with the increase of the frequency. The results indicate that the electric properties of the hot press moulded wheat gluten are subject to the compaction rate of the material structure.

对小麦麸质模压板的电性能研究表明，干态下其介电性能随电场频率增加而下降，但变化小；湿态下其介电性能明显提高，且随频率增加迅速下降，超过10^4Hz后区域变化趋于稳定；热压小麦麸质材料的电阻率随频率的增加呈直线下降；小麦麸质热压材料的电性能主要决定于材料结构的密实程度。

Although the major trend of vegetation rising through the recent 22 years , hygrophilous plant s are gradually replaced by drought2enduring plant s because of drought variations , which means the habitat of the vegetation is becoming dry.

结果表明：近22a，长江源植被覆盖呈总体增加趋势，而高寒草甸退化较严重，喜湿植被退化快于耐干旱植被，植被的生存环境趋于干旱化。

With the increasement of business competition and the development of technology , the deference among products has diminished .

随着市场竞争的加剧和科学技术的发展，产品之间的差异性越来越趋于同质化，以文字符号为主导的媒介文化已经发生转变，逐渐形成一种以图像为主的&视觉文化&全球景观。

Increase the bone marrow cell component while reduce the fat component, abnormal the caryon and cytomembrane structure of bone marrow cell and stromal cell, enrich the ribose body, mitochondrion and rough surfaced endoplasmic reticulum in cytoplasm of several organs and tissues, embody abvious improvement of heart muscle, liver, immnune organs, incretory organs and sexual gland.

增加免疫介导型再障小鼠的骨髓细胞成分，减少脂肪成分。使骨髓细胞和基质细胞的细胞核和细胞膜结构趋于正常，使多种脏器组织的细胞浆内核糖体丰富，线粒体及粗面内质网发达。对心、肝、免疫器官、内分泌器官及性腺等亦有明显的改善作用。

By using the laser-inharmonic oscillator system model, it was concluded that the bipolar inharmonic oscillator will be drastically stimulated when the laser reaches near-resonance frequency, the relative movements and total system momentum of the molecules will also rapidly increase, cause easy breaking of the bonds and links.

用得到的&激光-偶极非谐振子&相互作用的一些关系式，可导出当激光频率趋于&近共振频率&时，非谐振子将受到急剧激发，相对位移及动量也剧烈增大，振子震荡加剧，极易引起链、键的断裂。

Mean shape index andmean patch fractal dimension in 2003 is smaller than that in 1993. The landscape shapes innatural and half-natural condition tend to be simplifying. And the controlling effect of regionalecology may be enervated.

同时，黑龙江省2003年的斑块平均形状指数和分形维数小于1993年，自然、半自然状态的景观的形状趋于简单化，区域生态调节作用有所削弱。

The degree of crystallinity of PTMO and the lamellar thickness of the crystallites were found to increase with increasing λ.

拉伸对体系中非结晶的高频分子运动并没有明显的影响，拉伸使得结晶区更加趋于完善。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
