This paper discusses singularities, inflection points and convexity of FB-spline curves in terms of their control polygons, and gives the necessary and sufficient conditions for testing when FB-spline curves have one or two inflection points, or a cusp, or a loop, or none of the above points by the envelope theory and the topological mapping method.

文章利用包络理论和拓扑映射的方法，讨论了FB-样条曲线的奇拐点和曲线性质，并给出了依据控制多边形判断FB-样条曲线出现1个或2个拐点、1个尖点、1个二重点以及处处为凸的充分必要条件；最后给出了FB-样条曲线的奇点、拐点以及二重点在λ-μ平面上的分布图。

The following central point within a small local region of current tracing point can be obtained based on the influence of neighboring points as well as the smoothness and fairness principle. Finally, a sequential of central points can be traced out efficiently without any iteration and a parametric curve can be reconstructed by interpolating the central points.

该方法仅从当前跟踪点的邻近点集与曲线重建光顺准则出发，无须迭代，可快速、有效地跟踪得到无序点集的一个中轴点列，最后再由此点列拟合出参数曲线。

An algorithm about picking element is presented in this paper: First,getting certain amounts of boundary points by contour tracing from a point near an element and calculating primal parameters; Then, picking the element completely by element tracing guided by these initial parameters, jumping over broken points and intersecting points; At last,deleting the picked element from the raster image and renewing other elements' information intersecting with the picked element.

本文提出一种图元拾取算法：首先从图元附近一点开始，经轮廓跟踪、参数拟合得到图元的初始参数；然后在初始参数引导下，对图元定向跟踪，跳过断点和交点，最大限度的拾取整个图元；最后在光栅图像上删除该图元，并恢复与之相交的其它图元的交点信息。

Known differential expression gene: In the 46 points of known differential expression gene, there were down - regulate gene expression 41 points and up- regulate gene expression 5 points; twenty - eight genes related to hypoxia/reoxygenation had not been reported and 18 genes had been reported.

已知差异表达基因：在46个已知差异表达基因中，表达下调的基因有41个，表达上调的基因有5个，未见报道的与缺氧/复氧处理相关基因23个，已报道的有18个。

In this algorithm, the strongest corner points is adaptively detected with Harris operator and (2n+1)×(2n+1) feature windows is selected for originally mutual gray correlative matching. Continental distance ratio invariant criterion is proposed, and consistency of motion vector is improved by eliminating error matching points with median filter. 9 pairs right points is preserved, 4 pairs composing 1 group, and 5 groups is random distributed to uncoil the motion vector equations. Last, stabilization precision is improved by averaging the 5 groups' solutions.

该方法用Harris算子自适应检测出最强壮的角点，开辟(2n+1)×(2n+1)特征窗进行灰度互相关初匹配；提出欧式距离之比不变准则，通过中值滤波剔除误匹配点，确保运动矢量较高的一致性；最后保留若干正确的匹配点对，分成多组解运动矢量方程，将多组解的平均值作为全局运动矢量以提高稳像精度。

System of calculation of number of boxes of spars for mechanic was improved, and now many factors will be taken into consideration: price, uniqueness, condition (if the item is in very poor condition you'll receive fewer points, if good - more points, and if the average - the usual number of points ), and presence of the SGM achievement "Mechanic Assistant".

数字系统的计算对机械进行了改进棒材的盒子，现在有很多因素需要考虑：价格，独特性，条件（如果该项目在十分恶劣的条件是你将获得较少的点，如果好-更多的积分，如果平均-通常的积分数），新成就"技工助手"

The first consequence is that the child will inevitably consider one parent "good", more willing to give in to his desires and the other parent "bad", always ready to prohibit him from doing something. But what makes matters worse is that the child, receiving conflicting messages on the same matter, does not absorb the rule. In other words, as he does not receive clear and univocal messages from the most important people, a child becomes incapable of building up stable reference points, because he acknowledges the concept that there is no such thing as fixed rules and that what parents say can be disputed. A child can also learn to exploit the different points of view to his advantage, turning each time the more permissive parent and ignoring the authority of the more severe one. This can also have important repercussions in the years that follow, because a person who has not learned specific reference points as a child, becomes incapable of respecting the simple rules even at school, at work and those of civil cohabitation. With inevitable consequences from a social and relationship point of view.

第一个我们得到的结论就是小孩子可能会推断只要是能够满足他的欲望的父亲或母亲就是「好的」，而将另一位总是禁止他做某些事情的父亲或母亲当作是「不好的」，但让情况变得更糟的是小孩，在同一个世界当中不断接受到冲突的讯息，但并没有理解这个规则，换句话说，他无法从最重要的人们身上收到清楚、明确的讯息，无法与其建立信赖关系，因为他认知到爸妈说的话是可以被质疑的，且没有任何修改的规则，一个小孩对於他的利益会有不同的观点，只要有一方放纵小孩，而小孩则会去忽视比较严格的那一方，接下来的几年影响力是持续的，因为当他还是孩子的时候他没有去学会那些特定的参考指标，所以就变得没有办法遵循那些很简单的规则，甚至是在学校、工作上或是一般社区的环境，从社交关系上来说这是无法避免的结论。

To eliminate the limit, a hybrid objective function weighted by antitangent function is constructed, which behaves like an objective function of norm for small data points and like an objective function of norm for large data points, restraining the influence of false data points on inversion procedure.

为了解决这一问题，利用反正切函数作为加权因子构造了反正切混合目标函数，并利用模型试验进行了验证。简要阐述了最优化目标函数的构造方法；给出了利用反正切函数构造混合目标函数的基本原理，并对目标函数的微分特征和概率特征进行了分析；利用模型论述了反正切混合目标函数中控制参数μ和σ的意义，μ控制反正切函数变化的速度，σ控制数据误差项被处理或加权的方式。

Results: With 3.5 years of average follow up time, score the function of the shoulder of these patients, fixation by AO plate (85 points), reconstructed coracoclavicular ligament by using Ethibond 5# suture (93 points), reconstructed coracoclavicular ligament by using suture anchor (95 points).

结果：三种手术方法术后平均随访3.5年，对患者肩关节进行评分，锁骨钩钢板固定患者平均评分为85分；ETHIBOND线固定患者平均评分为93分；缝合锚固定患者平均评分为95分。

Are countable sets:Λ-Γ,〓-Γ are either empty or countably infinite, where Γ denotes the set of γ-limit points of f; tree map's depth of attracting center is finite and the attracting center is Γ provded all the branching points are periodic points. In chapter Ⅲ. we discuss certain relationship between isolated chain recurrent point and eventually periodic point of some continua.

主要利用树的特殊偏序关系证明了：不在周期点集闭包中的ω极限点都有无限轨迹；Ω-〓，Ω-Γ为可数集，Λ-Γ，〓-Γ或为空集或可数无限，其中Γ为f的γ极限点集；当分支点都是周期点时，连续树映射的吸引中心深度有限，且吸引中心就是Γ。

The father that if work,mad father, love annoys, disposition is too indrawn the be short ofing that the father of Mu Ne, resign oneself to adversity causes father easily to love is broken; Communicate time effectively between father and son, Mu Zizhi to be less than a hour on average to wait a moment every week, it is the cause that causes the child to become addiction.

如工作狂的父亲、爱愤怒的父亲、性格过于内向木讷、逆来顺受的父亲都易造成父爱的缺失；父子、母子之间的有效沟通时间每周平均小于一小时等等，都是造成孩子成瘾的原因。

These are vandal proof and they come with a locking mechanism.

这是野蛮的证据，他们来到了锁机制。
