该方法应用确定性方法和正交最优化方法相结合，将容差域的2￣n个顶点离散为n＋1个约束条件，并利用不可微规划直接得到DCTT问题的最优解。

Methods The tangential curvature of the anterior cornea was measured every 0.3 mm from the apex in 360 meridians by an Orbscan-Ⅱ topographer.

中度近视无散光中国青年55人，采集Orbscan-Ⅱ角膜地形图上360条子午线、距角膜顶点0.3 mm为间隔的点的前表面曲率值。

In these circumstances it is needed to save coordinates of vertexes. If the topological structure of the mesh is altered, the corresponding topological index information also needs to be saved.

在这种情况下，需要保存随时间变化顶点坐标，如果网格拓扑结构也发生了变化，还需要保存相应的拓扑索引信息。

The mutiple-input mutiput-output logic function of vertex in state transition graph represents output of related state and the single output logic function represents state transition condition; we use a 8-tuple NetList to represent the structure implement of the result of controller synthesis.

状态转换图顶点中的多输入多输出逻辑函数表示对应状态的输出，图中边上的单输出逻辑函数表示状态转移条件；用一个八元组NetList表示控制器综合结果的结构实现，八元组包括输入符号，输出符号，状态存储器的输入，输出网络，状态转换网络，状态存储器，状态存储器的输出和状态存储器的初始输出。

As the cubic B-spline curves, each trigonometric polynomial curve segment was generated by four consecutive control points.

与三次B样条曲线类似。曲线的每一段由相继的4个控制顶点生成。

With the shape parameter, the trigonometric polynomial curves can be close to the cubic Bécurves or close to the given control polygon then the cubic Bécurves.

由四个控制顶点生成的曲线具有与三次B zier曲线类似的性质，但具有比三次B zier曲线更好的逼近性。

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。

With the shape parameters, the trigonometric polynomial curves can approach more to the quadratic Bézier curves or to the given control polygon than the quadratic Bézier curves.

由三个控制顶点生成的曲线具有与二次Bézier曲线类似的性质，但具有比二次Bézier曲线更好的逼近性。

The average osteotomed length from the tip of great trochanter to distal osteotomy site was 12.4 cm (9～15.1 cm).The osteotomy sites were healed in 11 patients at 3 months and 2 patients at 6 months after operation.

平均截骨长度从大粗隆顶点至截骨远端为12.4 cm(9～15.1 cm)。11例患者在术后3个月时截骨端愈合，2例患者在6个月随访时截骨端愈合。

For those who have an eye for the exquisitely done ultramodern, they will find that every detail in the hotel is a work of art and has reached the apex of design.

对于那些谁有一个超现代化的精致动人，他们会发现，每一个细节是酒店的一个艺术作品，并已达到顶点的设计眼睛。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
