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。

Put forward several problems that exist during the course of system development and program. Introduce some measures of distinguish that are often used in non-destructive detecting and echo wave crest. Then I depict one of the measures in detail that used in the course of non-destructive detection, which is the way of distinguishing whether defects exist or not. Then provide part core program to realize it. This paper also provides main flow chart through analyzing how main control program controls different parts to make the whole system more effective.

The body has 2 sections , the first of which reaches into the Christianity" s influence upon the transformation of Western Europe to feudal society : In the early middle ages Western Europe , Christianity together with the traditional ruling class , had reunified the political power of Roman empire with the help of "Divine Right to govern";In the meanwhile , it had contributed to the ethnic unity of the Roman races and the feudalization of Western Europe ; while the other section deals with the Christianity" s impact upon the transformation of Western Europe to capitalism : in the Late Middle Ages , Western Europe , with the emergence of cities , some social changes had taken place .

正文又分为两个部分：Ⅰ。基督教在西欧向封建社会转型中的作用：在西欧中世纪早期，基督教不仅为日尔曼人的统治提供了一套完备的思想理论体系，而且为孕育于两种不同背景下文化的融合搭起了桥梁，并在此基础上促成了西欧封建制的最终形成。Ⅱ。基督教在西欧向资本主义社会转型中的作用：中世纪后期，随着城市的兴起，西欧社会发生了一系列变化。

On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there -- on a mote of dust suspended in a sunbeam....

Yet before the floating impress of the woods could clear itself, suddenly the gladsome light leaped over hill and valley, casting amber, blue, and purple, and a tint of rich red rose; according to the scene they lit on, and the curtain flung around; yet all alike dispelling fear and the cloven hoof of darkness, all on the wings of hope advancing, and proclaiming,"God is here!"

然而，在树林的缥渺影象逝去之前，突然那欢悦的晨光跃过峰峦和山谷，照在琥珀色、蓝色、紫色又偏向红色的玫瑰上。光线所及，把照到的景致和撒开的帷幕分别绚染，而所有的一切都同样在驱散恐惧和黑暗的魔影，所有的一切都展开希望的翅膀，向前飞翔，并大声宣告，"上帝在此！"

In light of the Yankees' success with the YES Network, which broadcasts Yankees games and general hagiography, the Mets started their own cable network, SportsNet New York, this year. Last year, when most Mets games were carried on two cable channels, the games attracted an average of about 110,000 households. This year, on SNY, 215,000 households tune in.(While the Yankees continue to wallop the Mets in television ratings, drawing an average of about 318,000 households, for their games on YES, the Bronx Bombers are down slightly compared with last year, when they averaged about 324,000 households.)For the Yankees' part, Lonn A.

受到洋基成立主要用以转播洋基球赛以及播放洋基球员介绍的YES Network获得了巨大成功的启发，大都会也在今年成立了SportsNet New York ，去年主要由两家有线频道转播的大都会比赛，平均每场比赛吸引了110，000家庭观看，而今年由SNY转播的比赛，则平均吸引了215，000家庭收看（在此同时洋基仍然在收视率上领先大都会， YES频道平均每场比赛吸引318，000家庭收看转播，不过比起去年平均324，000家庭观看的数据略有滑落），在洋基这方面，球队的营运总管Lonn A。

Secondly, enrichment of 13C and 15N and their combination with NMR spectroscopy can help us study not only the dynamics of decomposition of organic materials but also the changes of their chemical structures during the turnover of the organic materials, which can provide more information in clarifying the C and N cycling and humification of the organic materials applied to soils.

本文根据已收集到的部分资料，对13C标记技术在土壤和植物营养中的应用情况作一简要综述，并在此基础上讨论了13C加富标记技术在研究植物光合作用、光合产物的去向以及标记秸杆在土壤中的分解等方面的应用及其注意点，旨在能为国内开展这方面的工作提供十分有用的参考

To the assembly of this General Council, and at the same time to Your Imperial Majesty, we have, even before this, in due manner and form of law, addressed ourselves and made appeal in this matter, by far the greatest and gravest.

The first took place over four days in April 1929, without landing but during which mail was dropped to the large German colony at Jaffa in Palestine .

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.
