was optimized by the immune algorithm. The artificial immune-genetic hybrid algorithm was used to improve the learning tactic and the steadiness of the DFNN. Based on the actual electricity price data of the American PJM power market, the proposed algorithm and the DFNN were applied in the complex problem of short-term electricity price forecasting. The comparison results indicate that the precision......
-proportioning,Yandi ore,whose price is relatively low,can be mixed as high as 40wt%.关键词:......
,such as its low dielectric constant and the low price of the raw material.We fabricated composites with titania and calcite as the filler in a B2O3-ZnO-BaO-P2O5 (BZBP) glass matrix and investigated......
ionic radii in REE sites,coordination number and linkage of polyhedra.In structures where exist two kinds of polyhedra,with the change of composition in REE site,both REEpolyhedron and anion group......
FTIR spectroscopy.The studies support the proposition that TDI(tolylene diisocyanate)acts as a coupling agent between the epoxy and polyethers,forming a urethane linkage with the former and the latter......
microscopy (SEM), indicating that linkage of cavities in large region would induce failure of the material. Moreover, presence of liquid phase at grain boundary also affects the superplastic deformation......
liquefied product-based polyurethane(LBPP-PU) adhesive. To analyze in depth the creation of urethane linkage among LBPP, PEG400 and 4, 4’-MDI, factors which had effects on the residue content were......

was covalently immobilized through an amide linkage by the direct coupling of the carboxylic acid of heparin with the amino group of APEG on PU surface using carbodiimide coupling reaction. The surface structure......
energy at all loading rates were higher than the elastic deformation components and the elastic strain energy,respectively.Finally,we established the linkage among the pore structure,indentation......
