In order to analyze the stiffness of 3D 4 directional braided composites, the homogenization theory based on the multi-scale perturbation theory was used as the basic theory. The virtual displacement principle was used to educe the homogenization formulation of effective elastic modulus and the schemes to solve the problem using finite element method. The effective elastic modulus of 3D braided composites were predicted by this method and the calculation results agree quite well with experiment results.

It is pointed out that the main tendency of this study is gradually turned from the traditional solution theory or semiempirical model to statistical mechanics theory , from primitive to nonprimitive electrolyte model, in o rder to estab lish the mo lecu lar thermodynam ic model at h igh level,which can predict them acroscopic thermodynamic properties of electrolyte solution system from the microscopic molecular and ionic parameters.

指出电解质溶液的研究已逐渐从经典的溶液理论和半经验模型转向用统计力学理论进行研究，从电解质的原始模型转向非原始模型。从分子和离子的微观参数出发建立高水平的热力学理论模型，以预测电解质溶液体系的宏观热力学性质，是发展的必然趋势。

Methods: We randomly collected 58 patients who had been suffering from androgenetic alopecia, and had been willing to accept the product trial after being informed. Then we obtained the macro images and micro images by dermoscopy as well in 0 weeks, 4 weeks, 8 weeks and 12 weeks. After observing these images, we measured the changes of numbers of terminal hair and its density parameter. In addition, we set up the experimental group and control group, and the efficacy was evaluated by own control.
