It was proposed in the 1960's and developed rapidly in the 1990's. However, some theory problems, for example, the fluid dynamics and mass transfer during the filling up period which could not be dealt with in conventional distillation theories has been remained unstudied. And the simulation and mathematical models have to be made based on some assumptions, which are different from the actual situation obviously. Therefore the further development of DACO was restrained in the past years.

该操作方法自20世纪60年代提出，90年代以来得到了迅速发展，但众多学者的研究基本上集中在优化操作及其与传统恒回流法的比较，而许多重要的基本理论问题至今缺乏研究，特别是传统精馏理论无法涉及的塔内无回流充液阶段的流体力学和传质问题一直没有得到很好解决，导致了动态累积循环操作法的数学模型和模拟计算只能以与塔内真实状况相差很大的简化假设为基础，这严重地阻碍着动态累积循环操作法的进一步发展。

H.伸缩环转动环伸缩环垫片前轴封 S D / L D / S L M E C H A N I C A L S E A L P U M P S SD/LD/SL SERIES PUMPS The SD/LD/SL series are dependable, self priming pumps. The full motor horsepower is translated into fow via the shaft. These pumps are used for a wide range of applications, from chemical transfer to process solution recirculation to waste treatment. This series is capable of self-priming up ro 20 feet of lift. The mechanical seal is a self-cooling, Tefon bellows which is cooled by the solution being pumped. The construction materials and seals avaiable make this pump extremely versatile. The horizontal design has a working temperature from167℉ to 194℉(75℃ to 90℃), depending on the material of construction, and can handle most chemical solutions. The SD/LD/SL series pumps are designed to run outside the tank or process module. The SD/LD series pumps incorporate a FRPP molded base, legs and pump-to-motor casing. There are no bolts or metallic parts in contact with the solution being pumped.

The perplexing fact is that by making some simple calculations with the available data, one is struck by the recognition, that already in the immediate future (2015) the percentage divisions between the renewable and the non-renewable sources will have to be inverted, simply to avoid that half of the world's population dies of hunger. The studies regarding the peaking of the world oil supplies and world uranium supplies has irrefutably confirmed the above stated prediction.

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

They do not hear our whimpers or understand our pleas. We're miserable and it's scary here we all would rather die. But since we don't we do our best to run away and hide. I know you think my story too sad to leave me be. You want to take me home with you, a happy little puppy. But please, though it is fearful to live here against our will. If you take me that leaves a spot another pup will fill. You can stop our suffering but not by taking us home. You must be strong and leave us here, unsold and all alone. For if you do not take me, then another pup won't come. And maybe he will not be shipped so far away from home. Tho some of us may not survive the cycle 'ere it falls. If we don't sell they will not need more puppies in these halls. And if they need no puppies then the Man will not bring more. Eventually it can all stop! You CAN close the door. So when you see a puppy face so sad and sweet and small.

他把我们全部塞在这些小小笼子里，我们长途跋涉，只能睡在粪便里现在我们坐在宠物店里，接受小孩子们的戏弄和捏挤他们听不见我们的哀哭，不懂得我们的哀祈我们处境悲惨，这里这么恐惧真是生不如死但是我们死不了，所以只能尽力躲避我知道你觉得我的故事太凄惨你不想让我在此久居你想把带我回家让我做只快乐的小狗但是，虽然我们不情愿充满恐惧地待在这里如果你带我走，另外一只小狗将步我的后尘被带到这里你可以帮我们解脱痛苦，但是不是用带我们回家的方式你一定要坚强，坚决把我们留在这里，无人问津，孤独凄凉因为如果你不带走我，另一只小狗就不会来到此地他可能就不会被从遥远的家里运来虽然我们中间有些小狗不会生存到这个循环的终止但如果我们卖不掉，他们就不需要更多的小狗如果他们不需要更多的小狗，那个人也不会带来更多总有一天这个循环会完全停止！
