原因与结果

According to the practical observation and result of WEPP model simulating, the rate of the soil erosion was the biggest when the slope was 18-23. The reasons were that hydraulic friction and change of the acceptant area-were decided by steep and slow of the slope.

用WEPP模型来模拟皇甫川流域坡面与侵蚀量的关系是可行的，根据试验观测及WEPP模型模拟得到结果，皇甫川地区的土壤侵蚀率在坡度是18~23℃时最大，原因主要有坡度的陡缓决定了水力阻力的大小和坡面承雨面积的改变等。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

In the NPC cell lines,loss of BLU expression correlated with hypermethylation of the 20 CpG sites in the 5′ region of BLU(approximately -292bp to -23bp upstream the translation start site)as revealed by bisulphite sequencing. Expression of the gene was restored aftertreatment with 5-aza-2-deoxycytidine in CNE2, suggesting that repression of BLUtranscription might at least be partially mediated by promoter methylation.

结果显示，BLU基因翻译起点ATG上游-292--23bp区间内的20个CpG位点在5例细胞系中均被完全或者部分甲基化，与基因的表达缺失呈负相关关系；去甲基化试剂5-Aza-CdR处理CNE2后基因表达部分恢复，说明甲基化至少是引起BLU基因转录抑制的部分原因。

The result of this research demonstrates that water sensitivity damage is the fundamental cause that fresh Water can't be injected normally; the quality of injected produced water is out of standard is one of the key factors causing reservoir damage; the mixing of produced water and formation water tends to produce calcic scale, being another key factor of causing reservoir damage.

研究结果表明：水敏性损害为清水不能正常注水的根本原因；注入水水质不达标是造成储层损害的关键因素之一；污水与地层水混合易结钙质垢，是污水造成储层损害的另一关键因素。

Based on the results of underground observations and model tests of simulated materials of immediate roof, it is expounded that fragmented roof belongs in cataclastic rock mass,and its caving characteristics is clarified in this paper too.

By the B3LYP calculation of DFT, the difference in changes of energy and charge of ion probe C〓 and C〓 interacting with hBN and graphite respectively and the difference in frontier orbital energy level reveal difference in electroaffinity of hBN and graphite. It could be indicated that hBN only shows weak electropositivity, and will not be able to accept electrons from metal.

根据密度泛函B3LYP方法的计算结果，从六方氮化硼与石墨的前线轨道能级和两者对离子探针的作用能及C〓和C〓的电荷变化不同所表现出的在电亲和性上的差异，揭示了金属难以插入六方氮化硼层间的原因是六方氮化硼仅显弱的电正性，不能接受金属转移来的电子。

Situation of the utilization of experiment resources:(1) The opening up of the laboratory are relatively weak aspect, so, in these schools, students have few chances to do extra-curricular experiments;(2)Almost all of schools teaching experiment instruments are used, less instrument is not used, the main reason for not used is that these experiment instruments are irrelevant with materials or they are obsolete and damaged;(3) Teachers always experimentalize according to the teaching materials step-by-step, there is no improvement;(4) Most teachers don\'t pay attention to the evaluation of experiment result, students merely write expriment report;(5) The teachers have realized some significance of inquiry experiments, but have not begun action consciously.

从实验教学过程和实验资源开发利用情况看：(1)实验室的开放是比较薄弱的环节，绝大多数学校只有上实验课时才开放实验室，因此这些学校的学生进行课外实验和小制作的机会很少；(2)绝大多数学校实验教学仪器的利用情况较好，闲置仪器较少，其闲置的原因主要是实验内容与教材无关或仪器陈旧损坏；(3)实验过程基本上是按教材提供的步骤进行，教师对实验过程和教学仪器的研究和改进较少；(4)很多教师不重视对实验结果的评价，学生很少写实验报告；(5)教师对探究性实验的意义已有认识，但还没形成自觉行动。

On the basis of Theory of Endowment and Ricardian Comparative Advantage Paradigm, this paper carry out dynamic empirical analysis on the forenamed phenomena on the aspect of evolution of factor endowment and technological progress. The result of our research shows that there exists prominent positive correlation between upgrading of Chinas exporting commodity structure and evolution of factor endowment and technological progress respectively, moreover, the upgrading attribute more to evolution of factor endowment than technological change.

基于要素禀赋论和李嘉图比较优势理论，本文从要素禀赋演进和技术进步两个方面对此进行了动态的经验实证，结果显示要素禀赋演进和技术进步均分别与我国出口商品结构升级存在显著的正相关的关系，并且，要素禀赋的演进构成了出口商品结构升级的主要原因，而技术进步的贡献相对较小。

The results show that, there is a white zonal area between the AZ61 and Al-alloyed coating, which indicates that a good metallurgical bonding is obtained. The coating shows typical hypoeutectic structure. Due to lots of Mg17Al12 phases in Al-alloyed coating, the corrosion resistance of AZ61 magnesium alloy is increased obviously.

结果表明，涂层与基体形成了扩散白亮带，实现了较好的冶金结合；涂层具有亚共晶组织的特点；大量的Mg17Al12相存在于涂层表面是耐腐蚀性能提高的主要原因。
