The article in recent years the research progress of disease of oral cavity of TP prevention and cure makes one overview. The compositive TP of the basic research 1.1 TP of 1 TP is the floorboard that phenolic apperception of a kind of many hydroxyl closes matter, 25% what hold tea dry weight about, its are main component includes to express gallnut of gallnut catechu element gallnut of element of catechu of gallnut of acerbity ester, watch, watch catechu element is acerbity element of catechu of ester, watch, express gallnut of gallnut catechu element among them acerbity ester content is highest, occupy the 80%[1] of catechu element about, fighting oxidation with its unique element structure, fight the position with fight the respect such as tumor to have choppy, significant. The 1.2 TP absorption in oral cavity and metabolization Lee [2] is measured normally inside a hour after healthy person is chewing green tea Xie Huo contains juice of gargle green tea, content of the TP in saliva is very high, after observing green tea passes salivary enzymatic hydrolyze, TP is slow release and in oral cavity;Yang of local play action [the salivary level after 3] checked 6 volunteers to drink tea, chroma of the TP in making clear the saliva after drinking tea as a result is serous TP pH indicator 2 times, and the salivary TP concentration that contains gargle tea solution a few minutes to be able to produce higher level, and TP can be absorbed through oral cavity mucous membrane.

The structural and photocatalytic properties of TiO〓 as well as surface acidity were greatly improved by sulfation. SO〓〓/TiO〓 solid superacid with Hammett constant Ho less than -12.14 was prepared by treating the TiO〓 with 1.0mol. L〓 sulfuric acid solution and then calcining at 450℃ for 3h. When compared to unmodified TiO〓, the SO〓〓/TiO〓 superacid catalyst exhibited higher anatase content, smaller crystal size, higher specific surface area, centralized pore size distribution, and the blue-shifted band edge of uv-vis adsorption spectra. Furthermore, the SO〓〓/TiO〓 superacid also showed excellent reaction activity and stability for CH〓Br photocatalytic decomposition even under the moist reaction conditions. The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.
