The standard mid-infrared spectra of fifteen kinds of tea that respectively belongs to slight fermentation (green tea, yellow tea, white tea), moderate fermentation (oolong tea) and deep fermentation tea (black tea, dark tea) are measured by Fourier transform infrared spectroscopy. By the visual analysis on the spectra it is found that they are strongly similar, so it is difficult to distinguish the...
Utilizing the TLM (transmission line method) method, this paper discussed the electromagnetic environment of vehicles under the condition of high electromagnetic pulse (EMP). The simulation results show that the amplitude of electromagnetic intensity of external is higher about an order than that of internal. While the nearer the stimulation, the greater the amplitude of electromagnetic intensity...
The grid is a distributed computing infrastructure that supports the sharing and coordinated use of various resources in virtual organizations. The grid can be used for compute intensive tasks and data intensive applications. Data mining algorithms are intensive compute and data, and spatial data are heterogeneous, multidimensional and stored at various places. Therefore, the grid can provide a computing...
