Fu-yang reservoirs pore structure and influence of Songfangtun Oil Field in Songliao basion;

Research on pore structure and permeability of nonwoven filtration materials;

Application of information integration technology in pore structure study;

Study of two dimensional photonic band gap structure;

Change of band gap structure of 1-D photonic crystal of periodic positive-negative index structure at angular incidence;

With the boundary conditions satisfied by the electromagnetic fields in the interface between the crystal and the clad,the characteristic equation to describe the band gap structure is deduced.

Computations of one-dimensional photonic crystal band-gap structures using Rouard's method;

The authors proposed a new model of one-dimensional photonic crystal composed of alternately arranged RHM and LHM layers, calculated numerically the transmission spectra of the model with the transfer matrix method, and theoretically analyzed characteristics of the band-gap structure.

Comparing with the periodical structure, its band-gap structure has some characteristics.

Effect of pyrolysis temperature on porous structure of anthracite chars produced at high temperatures;

Study on fractal features of the porous structure in sandstone reservoirs;

The experimental results show that the traditional analysis on physical properties of sandstone cannot describe the reservoir characteristics and porous structures of different sandstones filled with different types of bitumen.

The effects of these evolutionary patterns on oil recovery of reservoir and the variations of pore configuration,sensitivity,wettability and percolation mechanism of rock in the r.

Based on the test data of actual reservoir in Shengli Oilfield,the wettability of mercury in the course of mercury intrusion,the change of reservoir pore configuration,fluid property,varieties of composition of oil-gas accumulation power,were analyzed.
