Abstract: Smoked bamboo has been put into mass production. However, many heat release volatiles would produce air pollution during thermoplasticization process. Therefore, the heat release behavior of smoked bamboo biomass was studied by TD-GC/MS to make full use of and prevent the pollution of the volatile materials. The main constituents were acetic acid(43.95%), cyclotrisiloxane, hexamethyl-(15.89%), octasiloxane, 1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(8.22%), 1,3-benzodioxole, 5-(2-propenyl)- (4.8%), cyclodecasiloxane, eicosamethyl-(4.51%), etc at 100°С. And the main constituents were acetic acid(42.05%), 1-phenanthrenecarboxaldehyde,7-ethenyl- 1,2,3,4,4a, 4b,5,6,7,9,10,10a-dodecahydro-1,4a,7-trimethyl-(8.42%), bicyclo[2.2.1]heptan-2-one, 1,7,7-trimethyl-,(1r)- (8.12%), cyclotrisiloxane, hexamethyl-(6.17%), 1,3-benzodioxole, 5-(2- propenyl)-(5.26%), 4-nitro-4'-chlorodiphenylsulfoxide(3.13%), etc at 115°С. The heat release volatiles of smoked bamboo biomass might be used as biomedicines. Particularly, the volatiles had good application prospects and popularized value in purification of cedrol and acetic acid.

Abstract: Manufacturing green products is an important way for sustainable development of enterprises. In view of power shortage of green product innovation caused by the income uncertainty, combined with currently domestic conditions, the development of green products is divided into three stages: the innovation stage, the promotion stage and the popularization stage. Based on the game theory and related optimization approaches, how to make decision by manufactures at every stage are analyzed. The results show that, under the certain internal and external conditions, the innovator of the green product has the first-mover advantage, and the competition among peer manufactures is the important force and effective channel to spread the green products, and thus the consumer welfare is also increasing. The conclusions are helpful to guide the formulation and implementation of manufactures’ green-product development strategy, as well as the cultivation and development of the consumer market.

Abstract: Black bamboo is becoming a major biomass in rooms. Therefore, the chemical components from black bamboo were identified by TD-GC/MS. The main function components of black bamboo biomass at 40°С were acetic acid(24.71%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(17.58%), 1h-indole-2-carboxylic acid,6-(4-ethoxyphenyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-, isopropyl ester(16.85%), cyclooctasiloxane, hexadecamethyl-(15.28%), cyclotrisiloxane, hexamethyl-(4%), etc. And the main function components at 50°С were acetic acid(40.39%), 1,1,1,5,7,7,7-heptamethyl-3,3-bis(trimethylsiloxy)tetrasiloxane(24.47%), octasiloxane,1,1,3,3,5,5,7,7,9,9, 11,11,13,13,15,15-hexadecamethyl-(16.39%), bicyclo[2.2.1]heptan -2-one, 1,7,7- trimethyl-, (1s)- (3.73%), tricyclo[2.2.1.0(2,6)]heptane, 1,7-dimethyl-7-(4-methyl-3-pentenyl)- , (-)-(3.57%), etc. Black bamboo biomass was more healthy to human at 40°С than 60°С. So black bamboo biomass was fit to use in rooms.

Abstract: Basing on the analyzing assembly technology of the double eccentric semi-ball valvular, the boom-type assembly machine is designed to assemble half spherical valvular. The assembly machine can provide larger transmit torque at the ending tighten step, though the changing of two speeds and releasing the energy of flywheel. Semi-ball valve seat assembly machine will greatly increase the manufacture of semi-valve level and the production efficiency. And it has a good application value.

Abstract: Statechart has been utilized as a visual formalism for the modeling of complex systems. It illuminates the features on describing properties of causality, concurrency and synchronization. In this paper, we try to describe the behavioral of the traffic lights by using Statecharts. We use Boolean function to make the traffic light controller behavior in a certain way. This paper used Boolean function to analyze the models which are modeled by using Statecharts. Their formalism provides a clear means for presenting control logic. Finally, an example of traffic light controller system is examined successfully.

Abstract: The viscosity of blast furnace slag which was taken from Shuicheng Iron and Steel Group Co. Limited was experimentally measured by column whirling method using the ND-II slag viscosity tester. By adding analytical reagent CaO, SiO2, Al2O3, MgO and TiO2 in accordance with orthogonal design, the contents of compositions in slag were adjusted in CaO/SiO2=1.16-1.24, 14.06-17.06mass%Al2O3, 5-7mass%TiO2, 8.96-9.96mass%MgO. The results showed that the viscosity of BF slag decreased with increasing TiO2; when the Al2O3 content in the slag was 14.06%, the viscosity of BF slag had a lowest value, a highest value had for 15.56% Al2O3 content, and a lower value for 17.06% Al2O3 content. There is no significant effect on the viscosity by both the magnesia and the binary basicity.

Abstract: Internet of things is an ultimate development direction of the information age, while mine informatization is only way to realize the safety production and management of mining enterprise. In this paper, we research and simulate the human neural network system and propose the structure of internet of things based on human neural network. We connect all the objects and systems of the mines through mine internet of things to simulate the reflex activities of human body, regulate and control production, management and other links of the mining enterprises, so that it will become a coordinated and efficient whole.

Abstract: Nature reserve is a significant base for humans to understand, use and protect nature. This study has investigated the ecological environment of Taoyuan cave National Nature Reserve. The results show that: the forest coverage here is high with rich biodiversity; wildlife resources are rich and diverse; air quality and water quality are first class of national level and the average air negative ion concentration is 18,000 ions / cm3 with less bacteria in the air, mild and humid climate, abundant rainfall, multiple microclimate types and good quality of environment. This suggests that the ecological environment of Taoyuan cave National Nature Reserve is in good condition.

Abstract: College culture is the combination of college and culture with rich connotation and extension. There is an internal relation between college culture and development of economic society. A comprehensive understanding of the college’s role in the culture and a clear definitude of the college culture’s function in economic and social construction have a great significance for the establishment of an innovative country and a harmonious socialist society. To promote the cultural construction of Colleges, we must first clear the cultural connotation of college culture, that is, clear what kind of college culture is really needed by society, and then build the long-term mechanism for the construction of college culture.

Abstract: With the wide application of the Web databases (WDB), it has become a hot topic of the current research to make full use of data. WDB query interface is an important way to get the WDB data, it is a significant prerequisite to obtain the data efficiently that we can realize the full representation and extraction for WDB query interface. This paper presents a new representation based on owl for WDB query interface; at the same time this paper gives the extraction methods based on regular expression and watir for the context of each query interface, form information and the relationship information between the form fields. This work provides an important foundation for the further classification and integration of query interface.
