Quantitative analysis which is about the granularity composition, the characteristic of structure units and pores is carried out, also the relationship between moisture content translocation and microstructure is discussed.

Through establishing mathematical methods,the unit geometric model is built according to different view points and the unit structure is displayed truly from different angles.

Function Evaluation of Acrylonitrile Structural Unit of Polyacrylate Size Mixture;

Based on detailed analysis on sedimentary units of thick oil zones, this paper describes spatial form of single sandbody and boundary relation among different sandbodies through vertically subdividing sedimentary units and structural units and areally subdividing sedimentary microfacies.

Furthermore, surface relief of a single structural unit istent--shaped rather than invariant--plane--strain--typed and the tilt angles of the two sides are 9--10°an.

Two kinds of the most common molded pulp pad structure units were tested about their static load,and analyzed using statistical means.
