Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants. According to the established screening methods, we chose out a strain of actinomycetes, designed as AMBL-029C;(3) antioxidant purification: the fermentation broth was recovered by a series of separation techniques including centrifugation, Amberlite XAD-2 absorption, followed by MeOH elution and a successive TLC purification. The resulting primary purified compound [temperately designed as AMBL-029C-TS] was further analyzed by HPLC to monitor its purity;(4) physical-chemical characteristics: judging from the acid-base fractionation experiments, and the pH and temperature stability tests, the compound was deduced to be a acidic compound with the properties of low polarity and highly pH and temperature stable;(5) mechanism of the antioxidant: in comparison with some other known antioxidants, TS was subjected to investigate its antioxidant mechanism, together with BHT,-tocopherol, as well as two streptomyces metabolites, homogentisic acid and -phenylpyruvic acid, which were previously isolated as the natural antioxidants in our laboratory.

针对本实验目的，我们设计了以下的实验步骤﹔（1）二次代谢物回收及检测样本处理：我们将发酵所得的培养上清液，利用疏水吸附性树酯Amberlite XAD-2吸附回收，并以甲醇溶离及真空减压浓缩脱水等方式处理，以取得提供抗氧化活性筛选之检测样本；（2）抗氧化活性检测及菌种筛选：以「过氧化脂质」和「硫丙二醯尿」的生成量进行定性定量分析以作为抗氧化物质生产菌筛选之用；经此筛选程序，我们选获了具有抗氧化物质高生产力的菌株，命名为AMBL-029C；（3）抗氧化物质的分离纯化：针对生产菌株的发酵回收处理液，以矽胶薄层色层分离法经物质层析纯化后，并以高效能液相层析法(High performance liquid chromatography；HPLC)分析物质可得一初级纯化物质，命名为AMBL-029C-TS；（4）抗氧化物质的物理化学性质分析：由酸碱转溶（acid-base fractionation）实验得知，此抗氧化物质属於中低极性的强酸性物质，对温度（37℃-100℃）及酸碱度（pH3.0-13.0）均表现出高稳定性；（5）在抗氧化机制探讨方面，我们针对数种不同的抗氧化机制进行探讨，即： 1。

To establish new methods for highly sensitive time-resolved fluorescence bioassay, several new lanthanide fluorescence complexes were synthesized and used for the preparations of nanometer-sized lanthanide fluorescence biolabels. Novel lanthanide fluorescence nano-biolabels are uniform (25-55 nm in diameters),strongly fluorescent with long fluorescence lifetime, highly photostable and biocompatible.

This paper, based on the land utilization change data during 1997 to 2005, applies the information entropy and equilibrium theory to study the temporal-spatial changes in land utilization structure in Lingshui county, with results indicating: a first slow and then a fast rise in information entropy of land utilization structure in Lingshui county and a general trend of rising homogeneity in land utilization structure; the information entropy of land utilization structure ascends from NW to SE, where can be divided into five regions, ecological protected area, resort area, farmland protected area, ecological agricultural construction area and comprehensive industrial developing area; the economic factors and populational structure play a key part in land utilization structure changes via principle componential analysis.

基于陵水县1997-2005年土地利用变更数据，利用信息熵和均衡度的基本原理，对陵水县土地利用结构的时空变化进行实证分析。结果表明：1陵水县1997-2005年土地利用结构信息熵和均衡度呈现先缓慢增长、再加速增长的变化过程，总趋势是土地利用结构的均质性逐渐增强；2）陵水县土地利用结构信息熵从西北向东南逐渐递增，依次可分为生态保育区、风景旅游区，基本农田保护区、生态农业建设区和综合产业发展区5个区域；3）利用主成分分析，经济因素和人口结构对陵水县土地利用结构变化影响重大。

The univariate analysis between successful aging and MCI shows that education, marriage ,diet , exercise, somnus conduce to successful aging; drink ,smoke ,HBP , diabetes, COPD ,arthritis don"t conduce to successful aging .The multivariate analysis show that education, marriage ,diet ,exercise ,somnus conduce to successful aging; drink ,arthritis don"t conduce to successful aging.

成功老龄组与轻度认知损伤组单因素分析表明，文化程度、婚姻、饮食、饮酒、吸烟、锻炼、睡眠，高血压、糖尿病、慢性阻塞性肺病及关节炎病史等组间具有显著差异；多因素分析的结果提示较高的文化程度、婚姻、素食饮食、锻炼、正常的睡眠促进老龄化人群向成功老龄化转变，而饮酒、关节炎病史可使轻度认知功能损伤的可能性增加。

Besides, the effects of light and temperature on stomata have not been modelled in any mechanistic model.

在第一章中，通过综述气孔对环境因子响应的数学模型的文献，发现目前对描述和模拟气孔行为的经验模型和机理模型是脱节的，可供选择的气孔模型还不能满足理论分析和实际应用的需要；经验模型没有机理的支持，不能用于理论分析，没有普适性；机理模型都过于复杂，而且其中的一些参数难以确定，所以它们还只能作定性模拟，不能作定量预测，另外，对于光强和温度的影响还未见有人模拟。

It also discusses the application of CGU. It is evident there are some differences between the regulation and the accounting practice of public corporations. The difference is resulted from the lack of maneuverability for the specific principle. At the same time, the intention of profit manipulating of management and unperfected market also contribute to the difference expanding.
