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 computation implies that the influence of truncation error of up/downwards continuation is about 0.001 m2·s-2, the maximum error is only 0.11 m2·s-2, which can be ignored in CHAMP gravity field recovery. The influence of the reference gravity field error of up/downwards continuation is less than 0.1 m2·s-2 in general, but the maximum error can reach 1.3 m2·s-2. To reduce this error, a high-precision gravity field model should be used in the up/downwards continuation.

计算表明：延拓误差中的截断误差部分影响量级约0.001 m2·s-2，最大误差仅为0.11 m2·s-2，可完全忽略；延拓误差中的参考重力场模型误差影响随参考场选取的不同而有所差异，整体而言小于0.1 m2·s-2，但最大误差可达1.3 m2·s-2，采用高精度的参考重力场模型能大大减小延拓误差影响。

The CoFe2O4/TiO2 magnetic nano-photocatalysts has fairly good magnetic property. The X-ray diffraction, transmission electron microscopy and ultraviolet-visible technique were used to analyze the phase structure, size and spectrum response scope of the samples. The XRD indicated the anatase TiO2 was formed when TCF modified by plasma. The size of CoFe2O4 particles was about 20 nm. The diameter of CoFe2O4/TiO2 particles is in the range of 30~40 nm. So the shell of TiO2 enwraps closely around the core and the thickness is in the range of 10~20 nm.

Benzoate (400 mg/kg) or creatinine (400 mg/kg), two inhibitors of DAAO, blocked D-NNA-induced pressor responses in rats. Furthermore, the addition of the pure DAAO significantly potentiates L-NNA production rate in kidney homogenates by approximately 2-folds. The in vivo and in vitro results suggested that DAAO plays an essential role in the pressor responses elicited by D-NNA.

A multi-distance measurements method is employed in this paper. A single parameter fitting method and a double parameters (reduced scattering coefficient and amplitude factor) fitting method on the basis of the least square Newton fitting algorithm is used to derive the optical parameters respectively. For the finite-thickness homogenous tissue, it can be concluded that the rest terms in expressions of diffusion reflectance and transmittance for the corresponding tissue geometries that subtract the exponential term contained source-detector distance depend on the detected position weakly.

在多程测量的基础上，使用单参数最小二乘牛顿法拟合方法和双参数（约化散射系数、幅度因子）最小二乘牛顿法拟合方法，得到有限厚均匀组织的反射率分布和透射率分布公式中除去包含测量位置的指数项的其它部分对测量位置皆具有弱依赖性的结论，并对拟合结果进行了分析讨论；而对于有限厚平板状双层组织，可根据对反射测量结果及透射测量结果进行拟合所得的约化散射系数间的差异及常数因子的正负判断双层组织的可能结构分布。

We spent $272 million on flight simulators in 2000, and we'll spend a similar amount this year. Anyone who thinks that the annual charges for depreciation don't reflect a real cost - every bit as real as payroll or raw materials - should get an internship at a simulator company. Every year we spend amounts equal to our depreciation charge simply to stay in the same economic place - and then spend additional sums to grow.And growth is in prospect for FSI as far as the eye can see.

2000年我们投资2.72亿美元在购买飞行仿真器上头，今年的投资金额也约当此数，有谁胆敢说每年的折旧费用不算是真正的成本的，应该请他到飞行仿真公司打打工，让他知道每一分折旧都跟薪资或原料成本一样真实，每一年我们都必须投入约当于折旧金额的资金在更新设备上，以维持既有的竞争优势，而如果我们想要成长的话，就必须再投入额外的资金，对于FSI而言，其目前成长的前景依然可期。
