Rresults from those studies can be summariazed as follow:(1) A preliminary study no correlationship between the UV-VIS reflection spectrum of tomato fruit surface and the lycopene amount of tomato fruit was undertaken. Based on observation from this study, a damage-free and in-situ detection technique of lycopene amount from tomato was developed with UV-VIS reflection spectroscopy;(2) The geometrical isomers of lycopene were separated successfully on C30-HPLC-PDA-ELSD. The absorption coefficients of Z-isomers were consequently dedermined. The geometrical isomer composition of lycopene could therefore be assessed. Those efforts formed a solid base to identify the natural product from synthetic compound of lycopene;(3) Lycopene resource from the fruit of Autumn oliver was proved to be available for industrial application. An extraction methos of lycopene from the fruit of Autumn oliver by supercritical carbon dioxide was developed at laboratory scale;(4) A method to extract lycopene by supercritical liquid with improved efficiency was developed; Data from this investigation suggested that a proper raw material pre-extraction process was important for a better extraction efficiency;(5) Variation in the geometrical isomer composition of lycopene during its metabolish in rat was assessed. A large amount of Z-isomers were observed. This variation took place in serum;(6) The absorption rate and accumulation in serum of natural lycopene in rat were assessed;(7) Ability to quench singlet oxygen by different geometrical isomers of lycopene was compared;(8) It was detected that whether natural lycopene had functions to regule blood-lipids and LDL antioxidation;(9) A C31 degradation piece of lycopene was found in the prostate gland of rat.

The degradation of 2, 4-dichiorophoxyacetic acid (2, 4-D) by ozonation combined with sonication (03/US) was investigated. Based on the authors' first paper about the synergistic effect of ozone and US, this paper presents intermediate products of 2, 4-D degradation. The main intermediates were 2, 4-dichiorophenol, benzopuinone, hydroquinone and organic acids, such as maleic acid and oxalic acid and soon.

利用臭氧超声波联合工艺对苯氧羧酸类除草剂2，4-D进行降解研究，在前文探讨臭氧超声波之间协同效应的基础上，确定其中间产物种类主要有2，4-二氯苯酚、苯醌、氢醌以及小分子酸如顺丁烯二酸、草酸、甲酸、乙酸等。

The structure of sulfonated polys from DB is similar to that of sulfonated poly(arylene thioether phosphine oxide)s from TB. The latter could be regarded as the"product"of the former provided that the ether unit of the former was replaced by the thioether unit. The studies illustrated that the latter exhibited much better oxidative stability than the former. This is due to the fact that the thioether unit of the former was oxidized into the sulfone or sulfoxide unit in Fenton reagent, which inactivated the adjacent benzene rings and thus retarded the degradation reaction.

从结构上看，后者可以看成是前者的醚基团被硫醚基团取代后的&产物&，其耐氧化性能比前者好得多，这是因为后者的硫醚基团在Fenton试剂中被氧化成为砜或亚砜基团，而砜或亚砜基是钝化基团，钝化了与之相连的苯环，阻碍了降解反应。

Catechin, thearubigins, and theaflavins of Tibetan tea, and products of their oxidation, degradation and complexity, contain important elements to prevent cancer, and reduce cancer and mutation so as to maintain a strong ability to kill cancer cells. The tea is also noted to prevent forms of carcinogenic nitroso compound, and restrain some enzyme that could activate carcinogen. Tibetan tea is rich in many materials, such ascatechin,β-carotene, vitamin
