摘要：
In order to better utilize and recover the productive waste leaves from the Cinnamomum camphora,pyrolysis-GC/MS technology was used to analyze the possible top value-added components of benzene/ethanol extractives of Cinnamomum canphora leaves.Relative content of each component was determined by area normalization.95 compounds from 102 peaks representing 99.216% of the benzene/ethanol extractives of Cinnamomum camphora leaves were identified,and the main constituents were Hexadecanoic acid,4-nitrophenyl ester (17.336%),Vitamin E (4.804%),Oxirane,hexadecyl-(4.639%),2,6-Bis(3,4-methylenedioxyphenyl)-3,7-dioxabicyclo(3.3.0)octane (4.333%),1-Hexacosene (4.148%),Hexadecanoic acid,2-methoxy-,methyl ester (3.783%),1,19-Eicosadiene (3.607%),3-Cyclohexene-1-methanol,.alpha.,.alpha.4-trimethyl-(3.542%),.gamma.-Sitosterol (3.495%),Nonacosane (3.217%),.gamma.-Tocopherol (3.119%),Eucalyptol (2.23%),vanillin (2.742%),Heptacosane (2.182%),Pentatriacontane (2.039%),1-Nonadecene (2.011%),etc.The results of function analyses showed that the 350 ℃ pyrolyzate from benzene/ethanol extractives of waste leaves of Cinnamomum camphora are abundant in materials of noble natural medicines and cosmetic.
摘要：
As a material entity to disseminate information symbol, urban sculpture not only provides people with survival and the active space and visual pleasure, but also to be the important bonder for peoples. The cause of false cognition of urban sculpture information dissemination is that the audiences misunderstand the information of urban sculpture in the mind when receiving sculpture information. From the perspective of communication, we analyze the causes of cognitive biases in the urban sculpture in information dissemination. And we put forward the countermeasures to reduce cognitive biases and provide some enlightenment for design of urban sculpture.

摘要：
The surface of two kind of crop stalks(corn and sorghum stalk) was modified by cold plasma to improve surface bonding performance of stalks. The effect of cold plasma treatment on stalks' surface wettability was analyzed by using contact angle tester, and the surface topography and chemical composition variation of the treated stalks were studied by SEM-EDAX and FT-IR. The results showed that after treatment by cold plasma, the surface of crop stalks can be etched, and the weak boundary layer can be removed. The crop stalks' surface were covered with a large number of active functional groups, thus the surface bonding performance of the crop stalks can be improved quickly and effectively.
