Abstract: A method for parameterized design of Furniture product was presented and the Software Solidworks was further developed with VC++6.0 in this paper. Under the supporting of Solidworks, it was realized to vary the parameters of product to generate new one. As a result, the time and cost for the product development could be reduced greatly.

Abstract: CuO has been doped solely and together with BaO and SiO₂ into barium titanate by mixing and calcination. X-ray diffraction showed that the sample doped by CuO-BaO has stable second hexagonal phase while the samples doped by CuO, CuO-SiO₂ were of a pure perovskite phase. For CuO-BaO doping, the Curie temperature was decreased accompanied with higher εmax; while for CuO doping and CuO-SiO₂ codoping, the Curie temperature was increased with εmax decreased. The difference can be explained considering that Cu²⁺ ion could not only incorporate into the BaTiO₃ lattice, but also assemble in the boundary phase when CuO was doped solely. Besides, the mechanisms of CuO doping and SiO₂ doping could happen at one time.
