The purpose of this study was to analyze the expressive characteristics of Chinese shadow puppetry costumes. Literature study and case analysis were conducted using books, research papers, and materials from the Xi'an shadow puppetry museum. Based on the Chinese traditional costumes, the shape characteristics are utilized with the intaglio and embossing techniques, and the complex and unnecessary details are omitted to express the costume image in a characteristic and simple manner. Second, colour was used according to the traditional Chinese symbolic colour concept, and the brighter the colour, the higher the role's status. The colour was also used to express identity and character. In addition, relatively vivid and highly saturated colours were used for the transparent effect of the shadow puppetry. Third, a role's status is indicated by the density and completeness of the patterns; the higher the role's status, the more complex and sophisticated the patterns, and the lower the status, the simpler the patterns or no patterns are used. Fourth, the faith for blessing expressed in the shadow puppetry is a representative folk auspicious culture. The repertoire of the shadow puppetry and the patterns on the costumes worn by the puppets, express the culture in an implicit way to symbolize the meaning of auspicious things.

The radius and coordinate of sliding circle are taken as searching variables in slope stability analysis. Genetic algorithm is applied for searching for critical factor of safety. In order to search for critical factor of safety in slope stability analysis efficiently and in a robust manner, some improvements for simple genetic algorithm are proposed. Taking the advantages of efficiency of neighbor-search of the simulated annealing and the robustness of genetic algorithm, a hybrid optimization method is presented. The numerical computation shows that the procedure can determine the minimal factor of safety and be applied to slopes with any geometry, layering, pore pressure and external load distribution. The comparisons demonstrate that the genetic algorithm provides a same solution when compared with elasto-plastic finite element program.

As a highly hydrophilic fibrillar mineral in nature, attapulgite (ATP) is a promising new additive for preparation of ultrafiltration (UF) hybrid membrane. In this work, ATP particles, which were grafted with a new Gemini surfactant of Ethyl Stearate-di(octadecyl dimethyl ammonium chloride) to detach the crystal bundles to single crystal and enhance the uniform dispersion in an organic polymer matrix, were incorporated into poly(vinylidene fluoride) (PVDF) matrix, and PVDF/Gemini-ATP hybrid membranes for adsorptive removal of Ni(II) ions from aqueous solution were prepared via a phase inversion method. Chemical composition, crystalization and morphology of the modified ATP were characterized by Fourier transform infrared spectroscopy (FTIR), Transmission electron microscope (TEM) and X-ray diffraction (XRD), respectively. The morphology of the hybrid membrane was characterized by Scanning electron microscopy (SEM), the performance of permeability, hydrophilicity and adsorption of Ni(II) ions were studied, and the adsorption kinetics of the PVDF/ATP hybrid membranes were particular concerned. The results showed that the hybrid membrane displayed a good thermal stability and hydrophilicity. Comparing with PVDF membrane, the hybrid membrane possessed good adsorption capacity for Ni(II) ions, and the adsorption kinetics fit well with Lagergren second-order equation.
