The software takes the best possible use of multimedia technique,es- pecially the three-dimensional animation,to vividly express the concept of crystal structure,lattice and structural motif.

The tri-element structure of environmental-social system is man,society and nature.

This tri-element structure began taking shape when the Han Dynasty opened the road toward the Western Regions,from then on the native Shanshan culture was in a c.

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.

Algorithm of image edge examination based on morphology multi-structural element;

Choosing appropriate structural elements to do morphologic operation on the fabric image can obtain weft and warp segmentation images ; then fabric density can be gained by analyzing weft and warp segmentation images.

The detection results of image edges are different morphologically for multi-scale structural elements.
