Mass spectrometric (MS) technique, including chemical ionization (CI), fast atom bombardment (FAB), and eletrospray ionization (ESI) has been applied to chiral discrimination and analysis.

In these modelings, the intermolecular interactions between chiral selector and enantiomers were calculated with quantum mechanics, molecular mechanics and molecular dynamics and the various molecular modelings have been established by X ray crystallography, nuclear magnetic resonance and computer simulation in order to study chiral discrimination mechanism in the process of separation of.

Chiral discriminations of N-[4-(1-pyrene)butyroyl]-D,L-phenylalanine (PPs) and dansyl-D,L-phenylalanine (DPs) by 2,2 -ditellurobis(2-deoxy-β-cyclodextrin) (2-TeCD) have been investigated using UV-Vis and fluorescence titration spectroscopy as well as molecular modeling simulation.

A novel recognition method called Active Discriminant Function (ADF) for handwriting recognition is presented.

As the most simple and directive method of man-machine conversation, handwriting recognition technique played an important role in intelligent device.

Handwritten recognition of Chinese characters is one important branch of pattern recognition and AI, which turns out to be a great challenge to computer owing to large quantity and written flexibility.
