It was put up by reaction-temperature, reaction-time, the ratio of catalyst and raw material, the kinds of esterify and dosage, the choice of solvent, catalyst life-span and so on. It was discovered that turpentine transform ratio was 86.29%, the yield ratio of terpineol was 68.89%, the selectivity of solid superacid catalyst was 79.84%.

二，松油醇的制备及结果讨论，从反应温度、时间、物料配比、酯化剂的种类与用量、溶剂的选择、催化剂寿命等几个进行了考察，结果发现反应温度为T3、时间L5小时、酯化剂用F3、物料配比为H3％、溶剂用G等时，松节油的转化率为86.29％、松油醇的收率为68.89％、固体超强酸催化剂的选择性为79.84％。

The term "high" refers to the product contains high technology, high accessional value , high investment amount, high risks, and high intelligence;"fast" means fast development of technologies, fast renewal generation of products, fast development in market and fast development of corporations;"sensitive" indicates that corporations are sensitive to the development of science and technologies, sensitive to the external changes in the market, and have more flexible in establishing organization structure, setting up rules for supervision, choosing technical methods and measurements, and arrangements for manufacturing processing.

高&，指产品技术含量高、附加值高、投资高、风险高、员工素质高（智力密集型和知识密集型）；&快&，指技术发展快、产品更新换代快、市场发展快、企业变化速度快；&灵，指企业对科学技术的发展反应灵敏，对市场外界条件变化反应灵敏，在组织结构的设置、管理制度的制定、技术手段和方法的选择、生产工艺的安排等方面都更为灵活。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

同时我们用磺化的2，2''-二-- 1，1''--联苯，以及它们的水溶性威尔金森型铑配合物和环辛二烯的阳离子铑配合物，在利用这些配合物作催化剂，考察它们在各种反应条件下对阿维菌素的选择加氢，由于反应条件以及复合催化剂体系的组成还需要进一步优化，虽然双齿膦配合物显示了较高的活性，然而选择性还有待进一步提高。

In bothsided LASIK, the corneal wound healing response is slight and is similar with LASIK. It creates the condition for preserving thickness of cornea stroma after surgery and is a good way to myopia treatment.

Effect of different surfactants on the UV intensity of Al(superscript 3+)-MXFX have been studied. Is Cetyl Trimethy-lammonium Bromide can increase the UV intensity of Al(superscript 3+)-MXFX is discovered. Based on this reaction, the reaction conditions in detail and proposed a simple, rapid and sensitive new method for the determination of MXFX by UV method is inve stigated.

Three reservoir clay minerals such as montmorillonite, kaolinite and illite were selected. Alkali consumption was investigated to define coeffect between these minerals and their corresponding mixtures under three amount ratios, solid/liquid ratios, and at different temperature conditions.

选择蒙脱石，高岭石，伊利石等三种在储层中最常见的储层粘土矿物，两两分别按2：0，1：1，0：2质量配比组成复配物系列；在30℃、50℃温度下按1：5，1：8，1：10固/液比分别与1.6%的Na2CO3溶液反应8h、120h、360h；监测反应前后碱液浓度的变化；计算了各条件下各自的绝对碱耗量。

In spite of this, the preparation of thiol-end functionalized PMMA was achieved by introducing a short block of polystyrene after the RAFT polymerization of MMA.Third, RAFT technique was applied to design and synthesize some well-defined poymers. Five monomers, lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate, poly methyl ether methacrylate, 4-(4\'-cyanobiphenyl-4-yloxy) butyl methacrylate and 2-ethyl methacrylate were chosen to RAFT homopolymerization or copolymerizations mediated by cumyl dithiobenzoate.
