摘要：
The results were following as: (1) During the soxhletic-extracting approach, the volume fraction of micro/nano particles in the diameter of 91.3 similar to 396nm, 0 similar to 190nm, 0 similar to 91.3m, 43.8 similar to 190nm, and 0 similar to 190nm occupy 92.9%, 93.0%, 95.1%, 89.8% and 92.4% respectively, the number fraction of micro/nano particles in the diameter of 0 similar to 91.3nm, 0 similar to 91.3nm, 0 similar to 91.3nm, 43.8 similar to 190nm, and 0 similar to 190nm occupy 94.0%, 99.5%, 99.5%, 95.5% and 99.7 % respectively. (2) The external electric and electromagnetic field-extracting approach could decrease the grouping number of leached particles from Eucalyptus urophlla wood. And the most significant apoptosis effect on leached particles was induced under the alternating electric field. (3) The extraction mass arrived at the maximum value when extracting time is about 5h in the soxhletic-extracting approach. it is the best effect of electromagnetic field among the four extracting approaches.
摘要：
We study two point boundary value problem with small periodic coefficients. It is difficult to obtain the numerical solution of the problem with high accuracy by using finite element method directly. A multiscale finite element method with high accuracy and its error estimate are presented by using homogenization method and multiscale asymptotic expansion and projective interpolation. The rigorous proofs of the results are proposed. Numerical results are presented to illustrate the theoretical results.

摘要：
In the course of the entire freightage, there are usually different combinations of transport modes can be chosen. With the limit time of whole freight, the combination of transport modes which causes the lowest cost will be chosen as the optimization. Firstly, the virtual network map of different combinations of transport modes between the starting place and the destination is constructed. Through endowing the different transport cost to the sections in the virtual network, the optimal problem of the combination of transport modes is converted into the shortest path problem of the virtual network. Finally, through integrating the Dijkstra heuristic algorithm and the kth shortest path algorithm, the scheme of the lowest transport cost combination of transport modes with the limit of freight time can be chosen effectively.
