carbon nanoparticles (CNPs ) prepared by electrochemical oxidation method possesses high surface activities, and based on strong affinities between water-soluble CNPs and fluorescent molecules, the mechanisms of fluorescence quenching towards Conjugated Polymers (CPs) was discussed, and CNPs could acted as a nanoquenchor for biochemistry application, such as detection of DNA molecules and other biomolecules by the similar way.

In order to realize the simulation testing and calibration of star tracker in the lab, a simulation algorithm for dynamic and celestial sphere star image was proposed. This algorithm could complete simulation of star image at any time and any visual axis point, also could realize in-orbit simulation according to a given track. A new method of space district dividing was also presented in order to improve the traditional method of space district dividing by ascension and declination, fully considered declination arc length gradually shortened with latitude increasing. It can remarkably enhance the updating frequency simulation star image.

A method of determining expansion center and expansion order is proposed in optical pattern recognition. To the reference image, choose an expansion center of one order, and works out optimal order by means of the expansion center. If the optimal order is equal to the selected order, the selected expansion center and order are the optimum; or else do it again choosing another order. Computer simulation results show that the method yields a sharper correlation peak, higher signal-to-noise ration and better correlation discrimination compared with the circular-harmonic filter.
