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.

Through above numerical analysis of the TiN coating/substrate system, some typical rules about the fatigue failure are found:(1) the fatigue damage of a coating/substrate system appears first on the interface, then expands along the interface and to the substrate, and finally causes the coatings broken and spalled;(2) under the cyclic loadings of tangential sliding and radial extrusion, the equivalent plastic damage on the interface is mainly generated by the shear stress and the accumulated plastic contributed by the increments of shear stress. Thus the change of the shear stress is the main factor for the contact fatigue damages of coating/substrate system;(3) the frictional coefficient, external loading and coating thickness have some influence on the carrying capacity and contact fatigue life for a coating/substrate system.
通过对TiN涂层/基体系统的数值模拟分析,得到了涂层/基体系统疲劳失效的一些典型规律:(1)、涂层基体的初始损伤首先出现在交界面处,然后沿界面并向基体中扩展,最后导致涂层断裂而发生剥落失效;(2)、在切向滑动和径向挤压循环载荷作用下,交界面处的塑性损伤主要是由剪应力τ产生,塑性累积也是由于△τ的变化引起,说明循环过程中剪应力变化是影响涂层接触疲劳破坏的主要因素;(3)、材料摩擦系数、外界载荷大小以及涂层厚度都对涂层/基体系统的承载能力以及疲劳寿命都有一定影响。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.
