The air drawing model of a polymer in a melt blowing process is established and solved by introducing the numerical computation results of the air jet flow field of the dual slot die. The influence of the melt blowing processing parameters on the fiber diameter is also discussed. A lower polymer throughput rate, higher polymer melt temperature, higher air temperature, and higher air velocity can yield finer fibers. The results show great potential of this research for the computer assisted design of melt blowing technology. Source

The tensile performance of the woven membrane materials shows three characters: nonlinear, anisotropic and non-elastic. Besides, when suffering from the bi-axial loads, the tensile property of the woven membrane material is more complicated. These features make the analysis of the tensile performance of woven membrane materials more difficult. The analysis methods including the elastic matrix method, the mathematical function method, and the mechanical model method have been discussed in details. Source

A new flexible multilayer thermal insulation material is presented for applications at harsh environment as high as 433 K or as low as 123 K. A heat transfer model is established and solved to study heat transfer through the material, including radiation, solid heat transfer and gas heat transfer. Comparison between the experimental results and the theoretical prediction shows that the model is feasible to be applied in engineering. The temperature distribution of samples with 10, 15, 20, 25, 30 layers, respectively, the radiation, solid and gas heat transfer of a sample with 10 layers are analyzed at harsh conditions (123 K and 433 K) and the normal condition as well. The theoretical thermal analysis provides an active instruction to an optimal design of such protective materials. Source

With the decline of the undergraduate education quality and the enormous employment pressure of undergraduates, the value of the undergraduate education has been questioned recently in China. One of the effective methods in a very short time to solve the problem is to strengthen the practice teaching. The earlier and the more of the practice teaching could benefit the teaching effect of theoretical knowledge, and at the same time, the employment pressure could be solved. Besides, the comprehensive quality of young teacher could be enhanced. Only the practice teaching has been highly emphasized by faculty members and administrators of the college and been initiatively required by the students, the value of the undergraduate education could be reflected. © 2011 Springer-Verlag Berlin Heidelberg.
