大豆异黄酮固体分散体片的制备研究中，由于大豆异黄酮固体分散体中的pvpk30含量较大，pvpk30本身的水溶性较好，不利于湿法制粒，且pvpk30是优良的干燥黏合剂，从而选择了全粉末直接压片法制备。

A new SVM is presented in this paper to solve the approximately linear separable problem of pattern recognition:First,we transform the two convex hulls which are made up of the approximately separable training set to make them separable;Second,we can figure out a separating hyperplane by halving the nearest points method or maximal margin method;Then,we get the approximately linear SVM by solving the dual problem of maximal margin method.

对模式分类中的近似线性可分问题提出了一种新的近似线性支持向量机：先对近似线性分类中的训练集所形成的两类凸壳进行了相似变形，使变形后的凸壳线性可分，再用平分最近点和最大间隔法求出理想的分划超平面，然后再通过求解最大间隔法的对偶问题得到基于相似压缩的近似线性SVM。

The ICU mortality was 13.2% and hospital mortality 26%. Median serum VEGF concentrations on day 0 were 423 pg/mL (interquartile range 159 and 858 pg/mL), and after 72 h were 521 pg/mL (IQR 182 and 1092 pg/mL), which were both higher than in healthy controls (P = 0.029 and 0.003, respectively).

我们获得在 ICU 内的死亡率为13.2%，院内死亡率为26%；并测得在第0天时的血清 VEGF 的中值为423 pg/mL (其四分位数区间为 159－858 pg/mL)，而在72h 时的血清 VEGF 的中值为521 pg/mL (其四分位数区间为 182－1092pg/mL)，而两者均高於健康对照组(P 值分别为0.029和0.003)。

Howerer, solid dispersion is one of the technologies of increasing the bioavailability of indissolvable drug, which force drug being at high disperdion state, Generally, drug particle diameter in solid dispersions was 0.001～0.1um, mainly dispersed condition was molecularity, metastable amorphism and colloidal state.

而固体分散体是增加难溶性药物的生物利用度的常用方法之一，其主要是使难溶性药物在水溶性载体中处于高度分散状态，一般而言，药物在固体分散体中的粒径为0.001～0.1μm，分散状态以分子状态、亚稳定态及无定形态或胶体状态多见。

在非线性振动理论中目前最具有代表性的一类系统是含有参数激励的非线性动力系统，在这类系统中有着极其丰富和复杂的动力学行为，如分岔、分形和混沌振动等。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

In the second part, we developed a new approach for the preparation of highly dispersed carbon black platinum nanoparticle with different geometric shapes by introducing clay (0 to 33%) as a dispersing agent in 5% Nafion co-solvent suspension without any organic solvents. FE-SEM analysis of CB/clay (100/0, 85/15, 67/33) was achieved CB particles with an average diameter of 40-60 nm. The hydrophilic property of the hybrid material was effectively improved in the presence of the clay was observed in sessile-drop test.

第二部分中我们发现在燃料电池之触媒制备常利用碳黑作为载体，碳黑在水中分散程度不一，而有机分散剂之电阻质较高常导致触媒用量提高增加成本，在本论文中我们利用几何片状结构的黏粒矿物与Nafion溶液做为分散剂巧妙的将碳黑分散，在不同黏土矿物与碳黑之不同比例(clay/CB 0/100， 15/85， 33/67)下进行分散，在SEM及TEM鉴定下证明其分散程度而碳黑粒径约40-60 nm。
