In this paper, we have made a systemic theoretic research on modelling and reshaping several types of spline curves/surfaces in CAGD. And some creative productions are given as follows. At first, the uniform C-B-spline basis is proved to be a normalized totally positive basis, and can be extended to a normalized B-basis. C-B-spline and C-Bézier basis, similar to B-spline basis and Bézier basis in algebraic space, are two bases in algebraic trigonometric space.

本文围绕着CAGD中常用的几种曲线曲面造型和形状调整进行了深入的研究，主要获得了以下一些成果：首先，证明了代数三角空间中的n次均匀C-B-spline基是一组标准全正基，并进一步扩充为一组标准B基。C-B-spline基与C-Bézier基是多项式与三角混合空间中的两组基，是适应工程实践中设计特殊曲线曲面的需要而产生的，类似于多项式空间中的B-spline基与Bézier基，是CAGD中重要的造型工具。

For example: Three series battery pack application, when the initial, A, B, C three single battery for 100% of capacity, but in the long-term use, the batteries have had uneven, resulting in at some point, A 80% of the remaining battery capacity, B Battery of the remaining 40% of capacity, C battery of the remaining 60% capacity; If Charged the three series pack batterys, due to the protection of high voltage, When A is charged 100% full and let the charger closed , B Battery capacity for only 60%, C for 80% of battery capacity and thus give rise to the battery pack inside the battery B and C is not fully charged.

这些不均衡现象不仅会使电池包容量变小，甚至还可能会造成严重的过充电、过放电等安全隐患。让我们来对这两种情况进行仔细分析：首先是针对电池包容量变小的情况；。以三串电池包应用为例，初始时，A、B、C三单体电池都为100%容量，但在长时间的使用下，各电池产生了不均衡，造成在某一时刻，A电池剩余80%容量，B电池剩余40%容量，C电池剩余60%容量；此时对电池包内进行充电，由于过高压保护的作用，当A电池充满100%而使充电器关闭时，B电池容量才为60%，C电池容量为80%，从而出现电池包内B电池和C电池有未充满电现象。

In section one, we introduce some background of the topic, in section two we review some basic and recent results about the structure and hierarchies of the computably enumerable degrees which are closely related to our topic- the algebraic structure of the plus cupping Turing degrees, in section three, we outline the basic principles of the priority tree argument, one of the main frameworks and tools of theorem proving in computability theory, and in section four, we prove a new result concerning the algebraic structure of the plus cupping Turing degrees that there exist two computably enumerable degrees a, b such that a, b ? PC, and the join a V b of a and b is high.

You can almost always determine the leads of a bipolar transistor with an ohm meter. b-e and b-c junctions will measure like a diode with the b-c junction reading slightly lower than the b-e junction when forward biased.

你几乎总是可以用欧姆表来判断双极性晶体管的脚位。b-e结和b-c结将像二级管那样测量，而且正向偏置时，b-c结的读数稍微比b-e结低一点。

3M i τi = 2 a i bi 3M i k = Ga i b i3 由后一式得 Gka i b i3 Mi = 3 60 Also Gk M =∑Mi = 3 i a i bi3 ∑ So we have: M a i b i3 = M 3 ∑ a ibi i Consequently we have:τ 3 Mb i = a i b i3 ∑ 3M k = G ∑ a i b i3 It is noticeable that: the shear stress of the midpoint of the long side of the narrow rectangle is considerably precise.

而 故有 Gk M =∑Mi = 3 M i a i bi3 ∑ a i b i3 = M 3 ∑ a ibi 从而有τ i 3 Mb i = a i b i3 ∑ 3M G ∑ a i b i3 k =值得注意的是：由上述公式给出的狭矩形长边中点的剪应力已相当精确，然而，由于应力集中的存在，两个狭矩形的连接处，可能存在远大于此的局部剪应力。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

Experiments show that C-B spline curve, uniform B-spline with shape parameter, hyperbolic polynomial uniform B-spline with shape parameter and trigonometric polynomial uniform B-spline with shape parameter can be used to produce some frequently used free form curves in the industrial field when the shape parameter is assigned with some specific values. This process is simpler than producing these free form curves by using controlling vertex.

实验证明，C-B样条曲线、带形状参数的均匀B样条曲线、带形状参数双曲多项式的均匀B样条曲线、带形状参数三角多项式的均匀B样条曲线都可利用形状参数的特定取值表示一些工业领域常用的自由曲线，这比起用控制顶点表示同样的自由曲线更为简单。
