Three dimensional (3D) honeycomb-like porous structures made up of nanoslices of hydroxy cupric phosphate heptahydrate Cu8(PO3OH2(PO4)4·7H2O single crystals were constructed by a facile assistant surface oxidation technology. The pore size of the 3D structure ranges from hundreds of nanometers to two micrometers, and the thickness of the two dimensional (2D) nanoslices is about 50~100 nm. The wettability of the porous surfaces was transformed from superhydrophilic to superhydrophobic by chemical modification with octadecanethiol or PDES.

相对于硬脂酸修饰表面，氟硅烷修饰表面对水滴具有更低的接触角滞后和较低的黏着，这可能是因为氟硅烷比硬脂酸具有更低的表面自由能所致。2、利用酸辅助的表面氧化技术制备了由Cu8(PO3OH)2(PO4)4·7H2O单晶组成的三维蜂巢状多孔结构，孔尺寸约为几百纳米到2微米，二维的纳米片厚度为50~100 nm。

Using ca pillary rube model of porous media,scaling coefficients of capillary pressure ar e deduced in this paper. The results show that the scaling coefficients, in the same porous medium, if any pair of two-phase (usually air-water two phase syst em is selected as the reference) capillary-saturation relationship is known, then the other two-phase (air-NAPL and NAPL-water) capillary-saturation relations hips can be obtained too.

In this paper, material properties of the segment of the porous metal-bonded diamond grinding wheel were researched by finite element simulation. Segments were manufactured according to the design result and their elastic modulus was measured. The key points are as follows: The influence of the porosity on the elastic modulus was analyzed through a finite element method. In the FEM model, the design variable only includes the porosity, and the tetrakaidecahedron model is applied as the microstructure model of porous metal matrix. The corresponding porosity was decided in order to meet the requirement of the elastic modulus.
