An improved three-cell model,which includes interior cells,two kinds of surface cells and corner cells,was proposed based on the geometrical characteristic of the yarns for 3-D 4-directional braided composite.

Establishment of an enterohemorrhagic Escherichia coli O157∶H7 attached HeLa cell model;

Establishing of cell model of adenomyosis in vitro;

Effects of ecdysterone on insulin sensitivity and glucose metabolism in insulin-resistant cell model;

The cellular model of mammary gland bioreactor is an in vitro culture system of mammary gland epithelium.

Transmitochondrial cytoplasmic hybrid (cybrid) cellular model is obtained by fusing ρ° cell line (host) completely devoid of mtDNA with cytoplasts produced by enucleation of cells (donor) derived from patients or controls.

A relatively reasonable three-cell model for 3D 4-directional braided composites is proposed based on the geometrical characteristic of the yarns.

To solve the problem that feature modeling depends on the designing history and data quantity is higher in the collaborative design,on the basis of analyzing the framework,providing a project of collaborative design system based on the cellular model,using XML keep the model s info and data binding of the documents,so we can handle the model s date on the net use RMI technology.

This paper discusses semantic feature modeling based on cellular model.
