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.

本文就近年来TP防治口腔疾病的探究进展作一综述。1 TP的基础探究1.1 TP的组成TP是一类多羟基酚类化合物的总称，约占茶叶干重的25%，其主要成份包括表没食子儿茶素没食子酸酯、表没食子儿茶素、表儿茶素没食子酸酯、表儿茶素等，其中表没食子儿茶素没食子酸酯含量最高，约占儿茶素的80%[1]，并以其独特的分子结构在抗氧化、抗突变、抗肿瘤等方面占有重要的地位。1.2 TP在口腔中的吸收和代谢Lee等[2]测得正常健康人在咀嚼绿茶叶或含漱绿茶液后的一个小时内，唾液中TP含量很高，并观察到绿茶通过唾液酶水解后，TP缓慢释放并在口腔局部发挥功能；Yang等[3]检查了6位志愿者饮茶后的唾液水平，结果表明饮茶后唾液中TP浓度是血浆TP浓度的2倍，而含漱茶溶液几分钟即可产生更高水平的唾液TP浓度，且TP可通过口腔黏膜吸收。

The main farmland soil types in Heilongjiang province are of white pulp soil, black soil, Chernozem, meadow soil. In this study, according the actual value of dry soil density, capacity soil moisture constant by weight, soil porosity with different soil in different vertical layers, applying statistical analysis method, to solve the internal relations among the three index above.

黑龙江省早作区耕地土壤主要类型有白浆土、黑土、黑钙土、草甸土，本项研究通过不同类型、不同层位土壤的比重、干容重、田间持水量、总孔隙率等的实测值，采用统计分析中回归分析方法，探索各项物理指标之间的内在关系。

Another initiative was also officially launched last year in June when our Prime Minister Mr Goh Chok unveiled the vision of Thinking Schools, Learning Nation as the direction we should take in preparing our young for the future.

去年六月，吴作栋总理正式提出了"重思考的学校、好学习的国家"的目标，并认为我们在培育年轻一代的工作上，应该朝这个方向走。

I love them all, even the double 'Waterlily'- but my favourite is Colchicum autumnale 'Album', and I team it up with Aster diviricatus, the wiry prostrate growth of the aster covering nicely during the summer when the colchicum foliage becomes dormant.

我喜欢所有的水仙，甚至包括重瓣的"莲花"——但是我最喜欢的是秋水仙"阿尔本"，我将它们与雏菊分开排成队列，整个夏天雏菊坚韧地匍匐成长着，对水仙作了很好的掩盖，而水仙的叶丛则处于睡眠状态。

This article is mainly discussed the relation between some important concepts and conclusions about the Limit of Sequence, the Limit, Continuity ,Differentiability, Integrability of Function, the Infinite Series , and the Limit, Continuity, Derivativeness,Differentiability of Multivariable Function ,as well as the Multiple Integral, and Integral with parameter .
