Results of XRD,SEM,and UV-Vis indicated that ZnS nanocrystals can grow in and fill in the void of opal template,and SiO2 microspheres of templates are dissolved so as to form some three dimensional ordered porous structure and to form the inverse opal ZnS photonic crystals. Compared with opal templates,ZnS-opal and inverse opal ZnS photonic crystals assembled with SiO2 spheres in the same diameter show good optical properties and exhibited photonic band gap. The photonic band gap position of inverse opal ZnS moves towards UV area compared with opal and ZnS-opal.

Second, transient flow for vertical well and fractural well in porous media with arealanisotropy has been researched in this paper. The analytic solution for vertical well andsemi-analytic solution for vertical fractural well is developed by using image inversion,superposition principle, Laplace transformation, Fourier transformation, as well as theirinverse transforms, and storage and skin are taken into account. For vertical fractural well,influence of pressure and productivity is studied when the orientation of artificial fractureisn't in accordance with the direction of major permeability, it is fundamental to evaluatepotential and analyze well test data.
