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。

Release in Baidu statement however hind, 14 days, alibaba, naughty the website such as treasure all is in home page head used " crisis of 3 deer milk powder pulls a Baidu is the gangdom on the largest network formerly "," the netizen explodes 3 deer Baidu of 3 million cover " wait for appalling caption.

然而就在百度声明发布后，14日，阿里巴巴、淘宝等网站均在首页头条使用了"三鹿奶粉危机扯出百度原是最大网上黑社会"、"网友爆三鹿300万罩百度"等骇人听闻的标题。

The website that is aimed at a company at that time was written medical certificate and the plan that return chain, oneself power is particularly great at that time, the old gave me 3 keywords at that time: Bridge of bridge of Wifi mobile phone, wireless net, Beijing wireless net, should come I undertake care is changed, I plan according to oneself above all in write one step by step did, the competition ability that I see WIFI mobile phone in Baidu index is not great, care changes the rate that go up should be the fastest, I update my website every day, increase oneself return chain, held to a month so, but see the rank of oneself website also often go up not to go, but this gives me of pepperbox died urgently, I am seeking a teacher every day, the friend asks, this is how to return a responsibility, how the rank of my website is old also go up not to go, but they are to use same word to tell me, fasten anxious, do care to change this thing not to come urgently, want to wait a moment, such I am able to bear or endure again strength waited 3 days, the following day, I rank a tool to be checked with the keyword, the rank contest of WIFI mobile phone discharged Baidu the 2nd, GG the position of the 5th, bridge of Beijing wireless net is on Baidu the 7th, GG the position of the 9th, when the work that sees oneself has positive result, really happy skipped to rise, follow ate close same.

当时就针对公司的网站写了诊断书和反链计划，当时自己的动力非凡大，老大当时给了我三个要害词：wifi手机、无线网桥、北京无线网桥，要来我进行忧化，我首先按照自己计划中写的一步步的都做了，我在百度指数中看WIFI手机的竞争力不大，忧化上去的速度应该是最快的，我就天天更新自己的网站，增加自己的反链，这样坚持了一个月，可是见自己的网站的排名老是也上不去，这可是把急性子的我给急死了，我天天追着老师，朋友问，这是怎么回事呀，我的网站的排名怎么老也上不去，可是他们都是用同样的话告诉我，别着急，做忧化这个事情急不来，要等等，这样我又耐着性子等了三天，第二天，我用要害词排名工具一查，WIFI手机的排名竞排到了百度第二，GG第五的位置，北京无线网桥在百度上是第七，GG第九的位置，当看到自己的劳动有成果的时候，真是开心的蹦了起来，就跟吃了密一样。

Can roll out, two products, think everybody knows, there is a kind of view in industry before, that is, the content that Baidu searchs is far be inferior to GG, the content of Baidu is too much rubbish content, actually really such also, the friend of a few major, use GG mostly, but Baidu is not willing however, tell the truth after all what the technology of Baidu does not have GG is good, but Baidu also is not fool, he also is in at the same time progress, the search that Baidu also can try hard to raise his after contains Troy; to have authoritative statistic GG is in today home with occupational the market of 30%, can think Baidu this country's biggest player, not can urgent, so he rolled out plan of what phoenix mew this year, this moment, very big friend of one part stationmaster has urgent, because still checking, adjust, think everybody saw the near future, a lot of websites, unhappy according to, home page falls authority, very big one part reason is this plan, baidu can raise what he searchs to contain Troy, at the same time this is meant, very big one part, rely on to collect, pilfer catenary, wait for a few heterodoxy, a few opportunistic sites will lose vivosphere, but at the same time also a few normal sites also got embroil, but do not be afraid of, believe the actual strength of Baidu, believe oneself, to finally, those who rank front row is normal site absolutely, and the site with the long time that build a station, the site with close user, content is the site that achieves formerly more, making a station have a few experience, that is: The network achieves myth, roam holds the post of our bank, sum up two words to hold to

会推出，两个产品，想想大家都知道吧，以前在业界有一种说法，那就是，百度搜索的内容远不如GG，百度的内容太多垃圾内容，其实也确实如此，一些专业的朋友，大多都用GG吧，但是百度却不愿意，说实话毕竟百度的技术没有GG的好，但是百度也不是傻子，他也同时在进步，以后百度也会努力提高自己的搜索含金量；具权威统计今天GG在国内以占领了百分之三十的市场，可想百度这个国内最大的玩家，能不急吗，所以他在今年就推出了什么凤巢计划，这个时候，很大一部分站长朋友有急了，因为还在测试，调整，想大家都看到了近期，很多网站，都不快照，首页降权，很大一部分原因都是这个计划吧，百度会提高自己搜索的含金量，同时这就意味着，很大一部分，靠采集，盗链，等一些旁门左道，的一些投机取巧的站点将失去生存空间，但是同时也有一些正规站点也受到了牵连，但是不要怕，相信百度的实力，相信自己，到最后，排名前列的绝对是正规的站点，而且建站时间长的站点，用户亲密的站点，内容多为原创的站点，在作站有几句体会，那就是：网络创神话，遨游任我行，总结两个字坚持

The results revealed that screwdrivers with triangle shaped handle could help subjects produce the maximum torque. Besides, using screwdrivers with hexagon shaped handle spent the least time, generated the minimum biceps muscle activity, and bad the least subjective fatigue rating. Moreover, wearing an anti-static glove or being barehanded can produced the maximum torque and spent the least time as well. Experiment 2 evaluates the handle diameter of screwdriver (30 mm, 34 mm or 38 mm) and operation plan. The results showed that the torque increased with the increase of the radius, the operation time and the brachioradialis muscle activity also increased with the increase of the radius.

本 研究共分为三次实验，实验一分析握把造型(八角形、锐角六角形、圆角六角形、枪型、圆角三角形)与手套(棉质手套、防静电手套、赤手)的影响，结果显示三角形造型握把可产生最大扭力，六角形造型握把的锁附螺丝时间最短、二头肌肌肉活动度最低、主观整体疲劳评比最低，防静电手套与赤手状态的扭力最大并且锁附螺丝时间最短；实验二比较握把直径(30 mm、34 mm、38 mm)与作业面的影响，结果显示直径越大扭力越大，但直径越小锁附螺丝时间则越短，且肱桡肌肌肉活动度越低。

Moreover, the actual allele frequency of most varieties deviates far from Hardy-Weinberg equilibrium. All PPB、na 、I、h、Gi and Fst have proved to be the references to elucidate that ISSR is a most powerful tool to analyze genetic diversity, compared with the RAPD marker and the allozyme marker is less strong ordinally. We could divided the 70 samples into A, B, C, D and E five groups using three methods according to genetic distance clustering. There is a bit displacement for few varieties in different clustering maps, but the most are similar to morphological analysis despite that there is still a great difference among cultivars in the same one group. The above results imply that the three methods have the different sensitivity and resolution in genetic distance analysis of close varieties. The Mantel test indicates that the results from the three kinds of markers have the significant correlation, which demonstrates that the number of the used three kinds of markers is enough to exactly detect the diversity of all 70 samples to ideal extent. And these methods can be used to evaluate the diversity of the whole group using the miscellaneous samples instead of the individual sample, of the Gerbera jamesonii are mainly from tissue culture plants. In conclusion, the above study results provide a reference for the application of three kinds of molecular markers to molecular marker-assisted breeding of flower. 2. The genetic diversity among the eight introduced cut-flower varieties of Ranunculus asiatica was analyzed by the ISSR markers. Based on the genetic clustering tree, all the colorful flower varieties are clustered into one group, and the white flower varieties into another group. Moreover, among the former group the yellow flower varieties are clustered into one sub-group, and the reddish flower varieties, such as rose color, pink, nacarat, are clusetered into another sub-group.

由三种分子标记的分析结果可以看出，等位基因平均值、观察杂合度、Fis值、Fit值皆较高，表明非洲菊等位基因较丰富，杂合基因偏多，且绝大部份品种的实际等位基因频率在品种内偏离了Hardy-Weinberg equilibrium；PP8、na、Ⅰ、h、Gi及Fst皆表明，ISSR检测遗传多样性的能力最强，其次是RAPD，等位酶最低；根据遗传距离进行聚类，三种方法都把70个品种分成A、B、C、D、E五个大组，每一组中除少数品种发生位移外，大部份品种分类结果相似，且与形态分析结果有相似性，但在每一组中，品种间的聚类差别较大，表明这三种方法在近距离品种间检测遗传变异时灵敏度及分辨力不同；Mantel检测表明，三种标记的分析结果有显著相关性，表明所用的三种分子方法的标记数量已经可以相对无偏地检测到70个品种间遗传变异；非洲菊为组培苗，三种标记的检测结果皆表明，混合样品可以作为个体样品的代表，对整个居群的遗传多样性进行评价；这些研究结果可为三种分子标记方法在花卉分子辅助育种中的进一步应用提供借鉴。

Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.
