We use the improved （G′/G）-expansion function method to calculate the exact solutions to the time- and space-fractional derivative foam drainage equation and the time- and space-fractional derivative nonlinear KdV equation. This method is efficient and powerful for solving wide classes of nonlinear evolution fractional order equations.展开更多

In the method, the integral weak form of control equations is employed, and the Lagrange multiplier is used to apply the essential boundary conditions. Then the corresponding formulas of the ICVEFG method for two-dimensional potential problems are obtained. Compared with the complex variable moving least-square （CVMLS） approximation proposed by Cheng, the functional in the ICVMLS approximation has an explicit physical meaning. Furthermore, the ICVEFG method has greater computational precision and efficiency. Three numerical examples are given to show the validity of the proposed method.展开更多

According to the demand of thePlan, there will be great changes among the current national standards and the professionalstandards for processing food, in which some standards will be integrated with others, somestandards will be cancelled, and some will be brought into the new standards system after the reviewof standards. The standards after being changed and the new national standards and the professionalstandards that need to be developed compose the new standards system for processing food.展开更多
