Photocatalyst CoPcS/TiO2 was prepared by sol-gel method. Composite CoPcS/TiO2/K2Ti4O9 was prepared by dipping. It was incandesced at various temperatures and modification effect was compared. The results showed that optical absorption of sample incandesce at 423K occurred significant red-shift. Light absorption width extended from ultraviolet region to visible region, especially there was an intensive absorption between 600 nm and 680 nm. X-ray diffraction spectrogram showed that TiO2 in sample still maintained anatase crystal form. Under the illumination of visible light, photocatalysis degradation experiment was taken with Orange II as simulated pollutants. Decoloration rate of Orange II was much improved. The rate can reach 85% in 300 minutes.

The evaluation of university financial performance evaluation is a complex system. Domestic and foreign scholars generally agreed that the evaluation of university financial performance is a difficult task. In this paper, a new evaluation model with principal component analysis (PCA) and particle swarm optimization (PSO) neural network is founded based on the comprehensive evaluation index system of university financial performance evaluation. A neural network model to the problem is trained by particle swarm optimization technique, which is a new adaptive algorithm based on a social-psychological metaphor, using principal component analysis to extract availability information and to solve a principal component. After empirical research with MATLAB7.0, we find that both the convergence speed and the evaluation accuracy are enhanced in comparison with the traditional neural network model.

Ecosystem health evaluation is the bridge in which the knowledge human learned can be applied to management and decision-making, and it is also the basis of ecological protection, ecological recovering and ecosystem management. The offshore area is the area where there is a strong interaction between land and ocean, and it is affected by human activities greatly. The evaluation, prediction and research of offshore area ecosystem health can provide ocean ecological management with scientific basis. In this paper, the concept and connotation of health of ocean Ecosystem is analyzed systematically and several problems existing in the present ecological healthy evaluation are pointed out. The healthy status of marine ecosystem and its environmental challenge are also indicated. What’s more, the emphasis of the study of marine ocean ecosystem health in the future has been suggested.
