Construction of the fingerprint database of Bohai crude oil;

In this paper,the design of security mechanism for B/S-based oil fingerprint database is realized and the principle of security mechanism for database and the security technology of database in common use are studied.

We summarize five main problems in establishing a DNA fingerprinting database of new Chinese maize cultivars: choice of maize varieties, choice of molecular techniques, problems of simple sequence repeat (SSR) techniques, choice of SSR markers and efficiency in techniques.

These screened normally-amplified multiplex-PCR-sets could be applied in maize DNA fingerprinting database.

This paper puts forward to constructing a real-texture library of virtual 3D scenic spot system for texture mapping to increase the efficiency mapping and the real-feeling of virtual 3D scenic spot system.

Based on the angle of systematical and scientific intention,this article discussed the building of texture library in the construction process of visual.

A method of capturing palmprint image without any limitation was proposed,and a palmprint database had been built using this method.
