The interpolate algorithms of three-order NURBS curve and double three-orders NURBS surface are presented. The expressions of partial derivative and normal curvature of NURBS surface are derived by the theory of differential geometry. The geometric characteristics of different curvature area of the free-form surfaces are analyzed in detail. All these work lays a theoretical foundation for constructing the cutter location calculating model of free-form surfaces NC machining. 2 On the basis of analyzing the methods of cutter path generation, the standard of evaluating the various methods of cutter path generation is presented. The method of generating cutter path with constant scallop height is presented for the first time.

本文以提高复杂曲面多坐标数控加工精度和加工效率为目的，在对国内外研究现状进行深入分析的基础上，对数控编程中各环节的关键技术问题进行了深入研究，主要内容包括以下几方面： 1 分析了复杂曲面各种造型方法的优缺点，给出了根据各种边界条件所确定自由曲面的NURBS表示方法以及三次NURBS曲线曲面反算算法；用微分几何理论推导了NURBS曲面的偏导矢及法曲率计算表达式；对曲面不同曲率特性区域的几何特征进行了深入分析，为建立复杂曲面的数控加工刀位计算模型奠定了理论基础。

The Adiri Natural Nurser Ultimate Bottle is 100% polycarbonate-free and bisphenol-A free, and retains the features babies and parents love in the Breastbottle? Nurser, as well as offers the latest high quality materials, a graceful design, and the new Fill, Twist and Feed ? system, engineered so that a parent or caregiver can quickly prepare a bottle, even with a hungry infant under one arm.

再次提到Adiri超级奶瓶是不含聚碳酸酯和BPA的，含有了所有宝宝和妈妈喜爱的奶瓶喂养优点，并且奶瓶使用绝对高质量的材质制成，配有典雅的造型和绝对简单的使用过程使得父母或者看护人可以很快的给已经饿了的宝宝冲好奶。

Like occasionalism, it presupposes theism, and, unlike occasionalism, it entails either that free will does not exist or that free will is compatible with determinism. The theory called epiphenomenalism simply denies that the metal can affect the physical, and contents itself with an explanation of why the mental appears to affect the physical.

前定和谐论类似偶然论预设了有神论，不类似偶然论，它导出"或者自由意志是不存在的，或者自由意志和决定论相容"）被称为"副现象论"的理论简单拒绝了精神对物理的作用，满足于去解释为什么"精神会表现出对物理的作用"。

Free will is content: Necessity is form. It is only by the analysis of the two sources of knowledge, standing to one another in the relation of form and content, that the mutually exclusive, and separately inconceivable ideas of free will and necessity are formed.

三、第三类根据是，我们对理性所必然要求的无穷无尽的因果关系的了解，而且为我们所理解的每一现象（因而也是人的每一次行动），作为以往的现象的结果和以后的现象的原因，应当有它的确定的地位。

Objective To study the change of intracellular free Ca2+ in the oocyst when it melanized and to find out the relationship between the melanized oocyst and its intracellular level of free Ca2+ in a Plasmodium-refractory strain of Anopheles dirus.

目的研究大劣按蚊蚊胃的约氏疟原虫卵囊黑化时卵囊内Ca~(2+)的变化，探讨疟原虫感染不易感蚊种时卵囊黑化与囊内Ca~(2+)的相互关系。

That needs the trace elements enter the reaction of maintaining free radicals metabolism balance which can enhance the activity of anti-oxidate enzyme,the trace elements which can enforce the oxidate of the free radical needed to be reduced.This may decrease or increase the relevent trace elements.

这就需要血液中能增强抗氧化酶活性的微量元素参与到维持氧自由基代谢平衡的反应中，以及减少利用血液中能增强氧自由基毒性作用的微量元素，这就使得血液中相应的微量元素含量减少或升高。

Molar Gibbs free energy or molar enthalpy of formation of complex oxysalt minerals with water is obtained by the summation of molar Gibbs free energy or molar enthalpy of formation of the part without water and water.

含水复杂含氧盐矿物摩尔生成Gibbs自由能或摩尔生成焓是不含水部分和水的摩尔生成Gibbs自由能或摩尔生成焓贡献值之和。

But after ultra-high pressure treatment, the all free amino acid can be measured except alanine and cystine and the content of asparagines is lower. The content of free amino acid is the highest in ultra-high pressure sterilize milk, the pasteurism milk is second, the ultra high temperature sterilized milk is lowest.

但是牛乳经过超高压杀菌处理以后，除丙氨酸和胱氨酸未检出，且超高压杀菌处理以后的天门冬氨酸的含量略低以外，其余游离氨基酸均可检出，而超高压杀菌牛乳中游离氨基酸的含量最高，巴氏杀菌乳中的含量次之，超高温瞬时杀菌乳中的含量最低。
