The method of confirming fracture parameter and development degree in carbonate reservoir;

According to the effects of volcanics fractured reservoir to the production, the tectonic stress field numerical modeling have been used to study the space distribution characteristic of the fracture parameter.

Studied are fracture identification and parameters extraction from micro resistivity images as well as seismic high resolution inversion of fracture parameters.

A model fordetermining theeffective elastic constantsof stitched lamina is established,in which the effectsof stitching parameterson elastic constantsofstitched lamina areanalyzed by consid- ering the nonuniform distribution and in- plan waviness of fibers induced by stitching.

The damage to stitching parameters such as stitching needle distance,row space,edge distance,single stitching or double stitching to the composite laminates was tested.

Stitched laminates with various stitching directions and stitch densities are experimentally studied, to reveal the effect of stitching parameters on in-plane tensile, compressive or shear properties and failure modes.

The effects of stitching parameters on tensile strength are discussed.

A contact problem of two contact blocks and nonlinear dynamic response of a plane arch are calculated, different jointed parameters, ini.
