On the other hand, after the reformation the unit specific energy consumption decreased 10 kilogram equal normal fuel oil per ton raw oil. In this paper, author analyse the principle and the advantages of the two stage riser fluidize catalytic cracking technology, where catalyst flow in relay and react in section, and short contact time and high c/o ratio. This paper propose a new method to calculate the catalyst circulation rate in each riser of a two stage riser fluidized catalytic crack unit and find out that the c/o ratio is lower than it should be by calculation use this method and give a suggestion to solve this problem.

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.

结果：PCA方法处理肾虚证和空白对照大鼠尿液数据显示，两组大鼠的数据可以在得分图实现分类，与对照组比较肾虚组大鼠由于氢化可的松诱导，大鼠机体进入一个过消耗后衰弱的状态，相关代谢发生显著变化，乳酸(δ 1.37)代谢发生堆积；二甲胺(δ 2.72)的含量增加，提示肾虚与肾功能异常是密切相关的；天冬氨酸(δ 2.83)，牛磺酸(δ 3.44， 3.25)，马尿酸(δ 7.84， 7.56， 7.64， 3.97)，肌氨酸(δ 3.87)等的相对积分面积明显下降，这预示糖皮质激素可能引起了肾上腺皮质分泌功能的损害；琥珀酸(δ 2.41)和柠檬酸(δ 2.53， 2.68)是三羧酸循环能量代谢及糖酵解的中间产物，其含量的降低，通常是由于线粒体功能紊乱所引起。

After finish the digestion, then flow back to the blood.also, during the period of liver and gallbladder concertrate in the hepatoenteral circulation,the bile acid can drain massively with the excrement.and more seriously after adding the fat feed stuff.if this condition go on, the fat cannot be absorbed in time and the energy will be wasted and cause some disease and etc.but after adding the appropriate exogenetic emulsifier,the question can be solved.

作为正常的机体，胆汁酸由肝脏分泌，进入肠道，在完成消化，回流入血液，又在肝脏和胆囊重新富集的肝肠循环的过程中，会经过粪便大量流失。在脂肪含量较高的饲料配方下，流失更为严重。日肝脏分泌量不足弥补流失量，会造成脂肪消化的阻滞，能量的浪费，且易诱发肝胆代谢紊乱等各种疾病。得不到消化吸收的油脂，在肠道内被噬油微生物降解，使噬油微生物类群大量增殖，打破原来肠道内微生态平衡，产生腹泻等菌群失调症，以上的问题，都是由于脂肪乳化作用不足和脂肪代谢失调造成的。在补充了合适本物种须求的外源性乳化剂后，问题可得到解决。

The thesis is based on income question, forest coverage rate and grop production.to beging with, date envelopment analysis is proved that it can be applicated into grain for green in shan-bei district, and then in view of the fact, seven esential factors which have influence on the project are found out: expense of dam, expense of crop,expense of cash tree ,expense of defense tree,other economic crop,expense of grass and graziery;and the output factors include:income of gdp,pure income per captia,the area of decreasing land loss,graziery income ,crop production,income of tree,the totle income of economic crop.after the date of each facts are puted into dea model,unefficiencial decision making units found.the data that are got through adjusting unefficiencial dmus dy dea can offer guide in shanbei district upgrading of an industrial structure.at the same time ,taking into account some possible problems in or after grain for green in shan-bei district,the thesis bring out some propesal to improve the circumstance,enhance the life level and putthe relation of population,resource and circumstance into a healthy orbit.

论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。

When the self-etched adhesives (Contax, Clearfil TRI-S Bond) were used for the surface treatment of sclerotic dentin, the results of thermal circlings showed that, for Contax, 5,000 times thermal circlings did not weakened the bond strength, while the bond strength after 10,000 times thermal circlings significantly lower than that before circling; for Clearfil TRI-S Bond, 5,000 times thermal circlings significantly weakened the bond strength, while 10,000 times thermal circlings weakened it further.

选择自酸蚀系统粘接剂Contax和Clearfil TRI-S Bond粘接非龋性硬化牙本质，分别测量冷热循环0次，5000次及10000次时的微拉伸粘接强度，结果显示：Contax粘接剂冷热循环5000次后粘接强度无明显下降，而循环10000次后粘接强度明显下降；Clearfil TRI-S Bond粘接冷热循环5000次后粘接强度明显下降，循环10000次后粘接强度进一步下降。

The eukaryotic translation initiation factor 5A (eIF-5A) is a small acidic protein (18k Da), widely presents in all organisms from archebacteria to mammals but not in eubacteria, with highly conserved sequences. eIF5A is unique in that it is the only protein known to contain the unusual amino acid residue hypusine (hydroxyputrescine-lysine), which is essential for eIF5A function and is formed by post-translational modification of a specific lysine residue.

真核生物翻译起始因子5A(eIF5A)是一个分子量约18 kDa的酸性蛋白，其序列从古细菌到哺乳动物高度保守，并广泛存在于各种真核生物细胞中。eIF5A是迄今为止唯一一种已知含有特殊氨基酸残基hypusine的蛋白质。hypusine是一种蛋白翻译后修饰产物，它的形成对eIF5A的功能完整至关重要，相关的研究结果表明hypsine在控制细胞周期循环的过程当中扮演着一个重要的角色。
