The following points are emphasized:The operation models of adiabatic and diabatic distillation have been set up and the operation block, thermodynamics model and mathematical model in the simulation have been determined as well;(2)Based on the simulation and exergy analysis with Aspen Plus program, shortcut distillation design—DSTWU model and rigorous distillation design—RADFRAC model, the author has determined the heat duty, exergy losses and the distribution of exergy losses along the adiabatic column, which will help the simulation and optimization of the diabatic distillation;(3)Diabatic distillation under various operation conditions has been simulated by using energy balance method and exergy analysis;(4)How the different mixture and the various degree of separation, number of trays and feed location influence exergy saving in diabatic distillation have also been discussed;(5)On the basis of the total exergy losses along the column, different schema of the heat transfer distribution along the column have been compared and analyzed;they can be classified in three categories: heat duty equipartition approach, empirical approach, separation degree matching approach. In conclusion, different heat transfer distribution along the column will have effect on total exergy losses. In particular, most satisfactory results have been obtained by using separation degree matching approach. In order to diminish the exergy losses, heat transfer distribution should meet the needs of the request of separation degree.And on this premise, the author makes his suggestion in increasing the proportion of heat supplied to the tray with minimum exergy losses and decreasing the proportion of heat supplied to the tray with the maximum exergy losses.

本文对透热精馏过程进行了模拟并对其节能效果的影响因素做了较为全面的分析和深入的研究，主要研究内容如下：(1)建立了常规精馏和透热精馏过程的模拟操作模块、热力学模型以及数学模型；(2)利用化工模拟软件Aspen Plus并分别采用DSTWU简捷模型和RADFRAC严格计算模型对常规精馏进行模拟计算和有效能分析，确定常规精馏塔的公用工程热负荷、有效能损失及有效能损失在塔内的分布，为透热精馏的模拟和优化提供数据参考；(3)对不同物系在不同分离度条件下进行透热精馏的模拟，分别采用能量衡算法和有效能分析法进行计算和分析；(4)探讨了各种因素如物系的选择、不同分离度、塔板数、进料位置对透热精馏节能效果的影响；(5)以全塔总有效能损失为比较基准，对热量在塔内的三种分布方案即热负荷平均分配法、经验法和分离度匹配法进行了对比分析并得出结论：塔内热量的不同分布方案对于全塔总有效能损失会产生影响，其中以分离度匹配法的节能效果最为理想，为减少有效能的损失，应使塔内的热量分布满足各塔板的分离度要求，并在此前提下，尽量减小有效能损失大的塔板的热负荷和增加有效能损失小的塔板的热负荷。

The results showed that the concentration of dissolved organic carbon in leachate from fresh litter fall was lower and that from F layer was higher for both plantations. In Castanopsis plantation, DOC concentration declined with the increasing number of leaching times, whereas that in China fir plantation increased at first then decreased.

光谱特征。结果表明，格氏栲和杉木人工林新近凋落物淋出液的DOC浓度较低，F层淋出液的DOC浓度较高；格氏栲凋落物淋出液的DOC浓度基本上随淋溶次数的增加而降低，杉木的则先升后降。

Studies indicate that while providing detergency at intake valves the detergents at the same time increased CCD to various extent. Comparing to regular gasoline, gasohol is more likely to form deposits at intake valves and combustion chamber and therefore needs more effective detergents.

研究发现有效的汽油清净剂在对进气阀起到清净作用的同时，均不同程度的增加了燃烧室的沉积物，这说明我国汽油清净剂的使用状况仅处于第三代汽油清净剂的发展水平上；乙醇汽油与普通汽油相比，更容易在进气阀与燃烧室内生成沉积物，因此更需要加入有效的汽油清净剂。

The results show that smaller height of reaction channel can shorten the time which reactants diffuse from channel to reaction surface, longer length of micro-channel can extend residence time of reactants on the catalyst surface, and consequently increase the methane conversion and hydrogen production. The pressure drop between inlet and outlet increases lineally with the increasing of length, while the height influences the pressure drop significantly when the height is less than 0.4 mm. Based on the overall consideration for the methane conversion and resistance characteristic generally, the suitable height of channel should be between 0.4 mm and 0.6 mm.

结果表明：较小的通道高度能够减小反应物在通道中的扩散时间，较长的反应通道长度能够增加反应物与催化剂的接触时间，甲烷转化率和产氢率提高；通道长度线性地影响微通道进出口压降的大小，而在通道高度小于0.4mm时，通道高度显著地影响进出口压降的大小；综合考虑微通道的重整性能和进出口压降等因素，通道高度在0.4~0.6mm之间较为合适。

The results showed that fishes of 11 orders, 18 families, and 46 species were represented in Changshu section of the Yangtze river. After the season, the total catch per unit effort increased sharply in the section; the dominant species were mainly commercial fishes such as Coilia ectenes, Mugil cephalus and Parabramis pekinensis and the annual change of dominant species was not obvious. The CPUE of Coilia ectenes had risen up and the trend of resource deterioration had been kept within limits. The caught rate of pintsized and juvenile fish rose markedly. The Margalef's index and Wilhm's index had an evident tendency of rising, while McNaughton's index and Pielou's index waved slightly.

研究结果表明：4~6月间常熟江段出现的鱼、虾、蟹类渔获物共有11目、18科、46种；春禁后，该江段总CPUE显著增加；优势种更替不明显，历年以刀鲚、鲻鱼、长春鳊等经济鱼类为主；刀鲚CPUE有所回升，资源衰退受到遏制；小型鱼类、幼鱼在渔获物中的比例明显上升； Margalef物种丰富度指数、Wilhm改进指数呈明显上升趋势，均匀度指数J′、优势度数Dw在窄幅范围波动。

In addition, the relation between AVS in sediments and heavy metals in overlying water was poorly studied.

AVS的存在增加了沉积物的吸附容量，但AVS经过酸化被除去后，与沉积物结合的重金属元素就会释放出来。

Secondly, the standard of biblioatherapy and harmony, 2000 edition of the people's Pharmacopoeia for the medication in a refineness, but stopple in the disinfaction process, inevitably there will be dissolubility, the dissolubility of the students'overloaded, refineness, if you will have direct impact on the quality of the drugs in this international standard has been added to the project control.

其次，标准注重与药典的协调统一，中华人民共和国药典2000年版规定了对药液的色泽要求，而胶塞在消毒灭菌过程中，不可避免地也会有溶出物，这些溶出物，如果色泽过重，将会直接影响药品的质量，在本标准中增加了该项目的控制。

The contents of volcanic grains increase upwards in the stratigraphic section, and become dominant during the Early Albian.

侏罗纪晚期，砂岩物源来自于稳定的被动大陆边缘，早白垩世Barremian期砂岩物源来自于被动大陆边缘和火山弧的双重供应，随地层变新火山物质的输入逐渐增加，至Albian早期达到顶峰。

Under certain experimental conditions,the Terbiumbasic Calbonate can be dissolved in aqueous solution of nicotinic acid to yield an Orange Tb Complex, which has a broad characteristic absorption band between, 370—410 nm The autoreduction of the Tb—Complex was studied by means of spectrophotometric method, It was determined by experiments that the reaction order is equal to two and the apparent activation energy of the auto—reduction is equal to 68.4±0,8KJ/mol.

在一定条件下，Tb的碱式碳酸盐可以溶解在烟酸的水溶液中形成橙黄色的络合物，该络合物在390nm波长附近有一宽带特征吸收峰。消光值在0。～1.0范围內与Tb的浓度具有直线关系。分光光度法对Tb自还原反应研究确定：于15℃及烟酸浓度为0.35M时，当pH值小于6.0条件下，随pH值的增加，其自还原速度常数减小，该自还原反应级数为二，反应活化能为68.4±0.8KJ/mo1。

Root activity of eggplant seedling decreased with the concentration of the methanol isolatable components increasing. Autotoxic substances in the methanol isolatable fraction suppressed the absorption of NO〓, PO〓, K〓, Mg〓 and Ca〓, implying the inhibition effect of the substances on ion uptake was one of the important mechanisms in allelopathy.

茄子幼苗的根系活力随水提物中醇溶性组分浓度的增加而降低，同时植株对NO〓、PO〓、K〓、Mg〓、Ca〓等离子的吸收受阻，因此抑制离子吸收是水提物中自毒物质的重要效应之一。

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。
