This paper first summarizes recent researches on this topic, and then proposes some methods for curve modeling with cubic algebraic curve based on pure geometric constraints that involve control points, tangent directions and curvatures.

然后提出了一种基于几何约束的三次代数曲线的插值方法，该方法完全通过几何量如控制顶点、切线和曲率来控制三次代数曲线的形状，使得对三次代数曲线的编辑与对三次 B-样条曲线的编辑一样灵活方便。

So we understand to once and actually usually take place of the bad factory house adds plant egg white(soybean egg white etc. corn egg white) in the origin should be the milk powder of animality egg white, this is already the first floor to cheat and commit crime, dishonest at least, but the widespread phenomenon in the in view of the fact industry, and have no obvious side effect to the human body, therefore is connive;But the protein content in the original inferior product very low, unexpectedly meet more unscrupulous plant egg white raw material to provide a company, add three gather cyanotype An, result in as a result currently result;Here our for the time being imagining is the beperhaps havior of the supplier, perhaps is three deer companies have intention to add, the basic reason for add lies in a current Kai surname settle nitrogen protein measurement method can test an always organic nitrogen content, rather than the nitrogen content in the particular protein, therefore, the method blemish was fume by the cupidity the exploitation that the milk powder manufactories of heart speculate, make the false and inferior product deceive to reach to mark, because they know three chlorine cyanotype An toxicities are again very small, disguise a protein content to reach a mark in the examination, but they didn't thought of that the toxicity is pimping three chlorine cyanotype An exactly will bring serious Bi to baby kid to wet system stone calculus, we even can guess, other adults of three deers use a milk powder in must also imply in great quantities similar chemistry product, just the adult will not get instant results of is endanger by body.

那么我们了解一下，实际上经常发生的不良厂家在本应该是动物性蛋白的奶粉里添加植物蛋白，这已经是第一层欺骗和犯罪，至少是不诚实了，但由于是业内的普遍现象，且对人体无明显副作用，因此被默许；而本来劣质产品中蛋白质含量就很低，没想到遇到更缺德的植物蛋白原料提供商，添加三聚氰胺，结果造成目前后果；这里我们姑且想象也许是供应商的行为，也许是三鹿公司有意添加，添加的根本原因在于现行的凯氏定氮蛋白质测定方法只能测试总有机氮含量，而非特定的蛋白质中氮含量，因此，方法缺陷被利欲熏心的奶粉制造商们所投机利用，使伪劣产品蒙混达标，因为他们知道三氯氰胺毒性很小，又能在检测中伪装蛋白质含量达标，但他们就没有想到毒性很小的三氯氰胺却恰恰会对婴幼儿造成严重的泌尿系统结石，我们甚至可以猜测，其它三鹿的成人用奶粉中一定也含有大量类似化学制剂，只是成人不会立竿见影的受到身体危害。

The Third Lateran Council (1179), convoked by Pope Alexander III, ended the schism (1159-77) of the antipope Callistus III and his predecessors.

第三lateran会（ 1176 ），召集了由教皇亚历山大三世，结束了裂（ 1159年至1177年）的对立教宗callistus三和他的前辈。

Three ways leads to the synthesis of fenclorin, one way discussed here has 3 steps. Stepl :benzonitrile using as raw material goes though dry hydrogen chloride and becomes a-imino phenylmethyl ether after meet carbinol.

解草啶的合成主要有三条路线，本文选取合成路线是以苯甲腈为原料，经三步反应而成：1、苯甲腈在干燥的氯化氢通入，与甲醇形成亚氨基苯甲醚，通入氨气后置换甲氧基得到苯基脒盐酸盐(收率76.18%)。2、苯基脒盐酸盐在碱性条件下与丙二酸二乙酯环合而得嘧啶醇(收率84.39%)。3、嘧啶醇在三氯氧磷中羟基被氯化得到产品解草啶(收率87.29%)。

And the optimum pH was 4-6 for the dechlorination reaction of 2,4-D, and pH between 2 and 8 were all suited for the reaction in Pd/Fe systems. Intermediate and final products of 2,4-D, HCH and chlordane with Pd/Fe were determined by GC/MS, and the possible dechlorination pathways were concluded: 2,4-D can be converted to phenoxyacetic acid through gradual hydrogenolysis, and HCH can be transformed to cyclohexatriene through dichloroelimination or dehydrochlorination.

通过GC/MS定性定量分析了三种目标污染物在Pd/Fe体系中发生还原脱氯反应过程中的反应物及最终产物，并根据反应产物推测分析了这三种有机污染物在催化还原反应体系中可能的反应途径：2，4-D主要通过逐级氢解最终生成彻底脱氯产物苯氧乙酸；而六六六则可能通过逐步双氯消除反应或脱氯化氢反应，最后生成环己三烯。

This article introduces three kinds of line cliping algorithms from the basic algorithm philosophy, the algorithm description,the algorithm steps and so on. Then it used the VC programming to realize these three algorithms on the basis of analysing the characteristics and the performance of three algorithms .

本文从算法基本思想、算法描述和算法步骤等方面介绍了三种直线段裁剪算法，在对三种算法的特点和性能进行分析的基础上，使用VC编程实现了这三种算法。
