The bronze wares will be corroded in varying degrees, under the influence of external and internal factors. This paper discusses the reaction mechanism of the bronze ware corrosion, through the analyses of the bronze ware composition and corrosion products. The current protection methods are also reviewed.

As an alternative energy, hydrogen energy is clean and most promising. In all kinds of methods for production of hydrogen, photo-catalysis decomposition of water is mostly researched. The catalyst is most critical in the photolysis of water. In this paper, photolysis of water by solar energy,improving efficiency of photo-catalysis reaction and development of photo-catalyst are reviewed.

Blood is an indispensable component to the human body and animals. It is an important way to change the type of blood and synthesize man-made blood for improving the supply of blood. That is the direction which our chemists, biologists and professional doctors should make great efforts to.

Inquiry study is a new learning way which reflects the new course ideas, and establishing hypothesis is the core factors in inquiry study. In this paper, the methods of establishing hypothesis is described briefly from four aspects, and three types of cases which specify the application of hypothesis in inquiry study are listed.
