摘要:
The article mainly discusses the application situation on the solar energy wood drying in China, and summarizes its advantages and problems in the real application. Because solar energy is low in thermal density, intermittent, and it is affected by weather, these have very big limitation to use solar energy in the actual production process. Based on these, it is introduced that the advantages of thermal energy storage technology in wood drying process of solar energy, the main application modes and the actual application status. It summarizes the major thermal energy storage materials and their basic characteristics, discusses the application prospect and the importance on the latent heat storage technology in wood drying.

摘要:
This experiment is performed to investigate heat transfer characteristics with the PCM microcapsule slurry in a solid phase state at a horizontal rectangular enclosure heating from below and cooling from top. Some important parameters are taken into account such as the mass concentration of the PCM, the temperature difference between heating plate and cooling plate, Nusselt number Nu, Rayleigh number Ra and the aspect ratio (width/height) of the horizontal rectangular enclosure. Experiment is done under the thermal steady condition in the PCM microcapsule slurry. Heat transfer coefficient is measured under various temperature differences in PCM mass concentrations of 10% and 20%. And relationship with Nusselt number Nu and Rayleigh number Ra is summarized to various heights H or the aspect ratio (width/height) Ar of enclosure.
摘要:
For getting higher quality and octahedron shape product Co3O4, the article studies precursor baked temperature, baked temperature route, baked condition affecting on apparent density, then points out obtaining octahedron shape Co3O4 technology. Test shows if the practice is accorded to the technology strictly, demanding standard Co3O4 can be obtained.

摘要:
As one of the chinese special product, it is very important for further machining of camellia oleifera fruit. The paper points out the fruit volume and density distribution, the specific heat capacity is about 2.1 similar to 2.5J/g degrees C. Under the microwave effect, the relation of critical fracture strength factor to rigidity has been calculated K-1c(2)= (1.1 similar to 9.8) *10(3)E. Practice and theory show that natural shape results the cracks locating the most raised parts of camellia oleifera fruit; Because the fibrous structure is the most weakness, the first cracking point is the fruit natural bottom.

摘要:
For the better acquiring knowledge needed by expert from cyberspace in Internet and stimulating inspiration for creation, a method of obtaining group knowledge of generalized expert for product innovation design is proposed in this paper. First, analysis of knowledge sample provided by universal expert is performed, and sample feature is extracted. Then, in response to the features of product innovation design, filed ontology with emotional semantic words is constructed. Based on filed ontology, the vocabulary of sample feature of expert knowledge is extended. On this condition, through searching and filtering, knowledge text of special expert from Internet is obtained. Using extraction technique of knowledge element, knowledge base of generalized expert group is constructed. Finally, an example is given to illustrate the effect of search and filtration of special expert knowledge and the building form and results of knowledge base of generalized expert group.
