Based on uniform design method, correlations between five flux components and Sn-9Zn/Cu wetting were studied. Take lauric acid, propylene glycol, decanol, polyethylene glycol 2000 and zinc chloride as independent variables Xi, wetting spreading area as function Y in the experiment. Every variable is divided into fifteen levels. Using computer software UST4.0, the experimental data were gradually statistical...
The construction of frame wavelets with compact supports is a meaningful problem in wavelet analysis. In particular, it is a hard work to construct the frame wavelets with explicit analytic forms. For a given n × n real expansive matrix A, the frame-sets with respect to A are a family of sets in Rn. Based on the frame-sets, a class of high-dimensional frame wavelets with analytic forms are constructed,...
