The optimal conditions of the pepsin hydrolysis of frame protein in catfish Claris lareza were investigated using a general-purpose rotation unitized design of the second power of four factors, and the content of soluble peptides was determined in the hydrolytic products. The Optimization of Design Expert 7.1.2 revealed that antibacterial activity of the frame protein hydrolysates was controlled by regulation of four process conditions.

采用四因子二次通用旋转设计，以抑菌率为测定指标，对胃蛋白酶水解革胡子鲶Claris lareza鱼骨蛋白的条件进行了优化，同时测定了酶解产物中可溶性肽的含量，以分析抑菌率与可溶性肽含量之间的相关关系。

Inside the source apply color to develop process in the tooth in formative of, such as four wreath vegetables deposition is in the tooth essence, will make tooth yellow, brown or dark gray, be called four wreaths plain tooths;If containing fluorine in the drinking water is excessive, may also cause fluorine spot tooth, the tooth noodles presents a white chalk color, the palm tree brown spot piece;If the tooth nerve is bad clay-cold, hemoglobin and germ resolve an outcome to combine to also make tooth black.

内源性着色是在牙齿发育过程中形成的，如四环素沉积在牙本质内，就会使得牙齿变成黄色、棕色或暗灰色，称为四环素牙；如果饮用水中含氟过多，也可能导致氟斑牙，牙面呈白粉笔色、棕褐色斑块；如果牙神经坏死后，血色素与细菌分解产物结合也可使牙齿变黑。

Furthermore,we present the method for designing quadratic Bezier developable surface:give four corner points of developable surface and two free designing parameters,the other two control vertexes are on the line connecting the linear interpolation point between the first two control vertexes and the linear interpolation point between the last two control vertexes,and they are the linear interpolation points between these two linear interpolation points respectively,namely,these four linear interpolation points are colinear.

提出了二次Bézier可展曲面的设计方法：给定可展曲面的4个角点a0、b0、a2、b2和两个自由设计参数？姿、？滋，则待求的2个控制顶点a1、b1是在前2个控制顶点a0、b0的线性插值点a*与后2个控制顶点a2、b2的线性插值点b*的连线上，并且也是a*、b*这2个线性插值点的线性插值，即这4点a*、a1、b1、b*共线。

Aiming at above problem, this paper put forward the strategy of separation as follows. Firstly, in view of great amount of coloring matter in solution, the quality of product is declined. So we decolor the solution by acticarbon, which makes 80% coloring matter be removed, but the loss of nucleotides is only about 2%. Secondly, on the basis of physical and chemical properties of four nucleotides, we first synthesized a kind of cation exchange resin by ourselves which is used to separate four matters preliminarily.

针对以上问题，本文提出了如下的分离策略：首先，由于酶解液中色素含量较多，使经树脂分离所得UMP和GMP中色素残留较多，最终导致成品质量的下降，所以我们用活性炭对酶解液进行脱色处理，使溶液中80％以上的色素被吸附除去，而核苷酸的吸附损失仅为2％左右。
