The results showed: when TLC solvent system was: chloroform - methanol - diethyl amine = 90:9:1, alkaloids from lotus leaves were well isolated, and five components were isolated and identified by spraying Dragendorff reagent. The optimal conditions of HPLC solvent system were: methanol- water - diethyl amine = 75:25:0.0125. Under the conditions, components of alkaloids from lotus leaves were separated very well, and ideal RP-HPLC peaks were obtained.5、Methods of High Speed Counter Current Chromatography and preparative High Performance Liquid Chromatography applied to identify and purify alkaloids from lotus leaves were set up. When solvent system of HSCCC was: chloroform - methanol - water (pH=4.00)= 4:3:2, speed of chromatogram was 700rpm, flow speed of the mobile phase was 2mL/min, four pure components relatively were attained by isolation and purification.

结果表明：薄层层析溶剂系统为氯仿：甲醇：二乙胺=90：9：1，使荷叶中的生物碱达到了较好的分离效果，并用改良的碘化铋钾试剂喷雾显色，共分离鉴别出了5种荷叶生物碱；分析型HPLC分析检测的较优溶剂系统为甲醇：水：二乙胺=75：25：0.0125，使荷叶生物碱的各个组分达到了基线分离，并获得了较好的峰形。5、建立了高速逆流色谱和制备型HPLC技术分离纯化荷叶生物碱的具体方法。H(来源：ABC46论文网www.abclunwen.com)SCCC法在溶剂系统为氯仿：甲醇：pH4.00的水=4：3：2，色谱仪转速为700rpm，流动相流速为2mL／min的条件下，分离纯化得到了4个纯度较高的化合物。

Comparisons between the results from the wind tunnel tests, numerical simulations and the field tests were performed to verify the accuracy of the CFD method. Then the advanced k-ε turbulence model was used to compute the mean pressures on a long span curve shaped roof with the front door open or not open.

在核实了数值模拟精度的基础上，运用改进的k-ε湍流模型对某曲面大跨网壳在大门开启和大门关闭两种不同工况下内、外表面的平均风压进行数值模拟研究，并考察了来流风向角和背景建筑对其风压分布的影响。

It is possible to preparing neutralizing MAb which target to active region of Stx2 by synthetical B cell epitope peptides. At present, the crystal structure of the compound of Stx2 and its ligand adenines has been resolved, and the active site of Stx2 is definite, which is the seventy-seventh amino acids, Ganimalon, of Stx2 A1 fragment.

Stx2通过B亚基与受体Gb3结合后，进入细胞，在弗林蛋白酶(一种钙敏感的丝氨酸蛋白酶)作用下A亚基被裂解为A1和A2两个片段，A1片断经内质网进入细胞质暴露毒性活性位点―A1片段发挥N-糖苷酶活性，导致真核细胞蛋白质合成的终止，最终导致细胞的死亡。

Now most oil fields have been high water-cut, so studing fluvial sandbody architecture can provide important academic evidence to realize the distribution of remained oil and hold peak or settled production, fn addition to ,how to combine the facts of macroscopical and microcosmic, and how to combine the result of well network and fields outcrop.then instruct production and practice, which is the stress of this article.

在目前大多数主力油田已进入高含水期的形势下，研究河道砂内部建筑结构，可以为了解剩余油分布规律，保持油田高产稳产，提供重要的理论依据。此外，如何将宏观与微观的因素结合起来，将密井网研究成果及野外露头研究成果有机的结合起来，用于指导油田生产实践，也是本次研究的重点之一。

The RAFT controlled growth of hydrophobic block led to the formation of well-defined poly-co-polystyrene amphiphilic copolymer, which was able to work as a polymeric stabilizer (self-stability). Finally, very stable latex was prepared, having no visible phase separation for several months.

这种方法在超声细乳化之后得到细乳液之后，不需要进一步搅拌，在加热聚合条件下即可最终形成自身非常稳定的乳液，该乳液放置一年时间仍(来源：Ad8B6969C论文网www.abclunwen.com)保持稳定。

With water levels falling rapidly at the peak of the dry season, a giant school of bass, a tasty fish that fetches a good price at markets, was swimming right into the nets being cast from a dozen small canoes here.

随着干旱季节，最严重的时期的到来，河水迅速退去，成群的、美味的、可以在市场上卖个好价钱的鲈鱼，可以一起涌进，十几艘小独木舟所撒下的网中。
