For curved face pattern the flexibility of glass tube curvature and the flexibility of stamp in the creation is to the in operation influence, and the 2 F PMMA in the 3D layer combined the influence of dint and capillary to do a superficial research.

对于曲面图案制作中玻璃管曲率与印章的弹性对操作中的影响，以及三维层叠中的两层PMMA结合力与毛细作用的影响做了粗浅的研究。

Due to the effect of curvature of shell, the equation of motion of elastic waves in shell is much more complex than that in plate. The method of operator factorization can't be directly used to solve the equation of motion of elastic waves in shell by reducing it to the second order partial differential equations.

由于壳体曲率的影响，使得壳体的弹性波动方程比平板的运动方程复杂得多，难以直接采用算子因式分解方法，将其化成二阶偏微分方程求解。

In the first part of the paper, we construct a family of 1 parameter cubic algebraic curves interpolating four given points and two tangent lines at the endpoints, and one can manipulate the shape of cubic algebraic curves by controlling the points or the tangent line directly.

该文提出的代数曲线的结构有两种，一种是插值平面上四点及两端点切线的三次代数曲线；另一种是插值两端点、两切线及两曲率的三次代数曲线。

This observation raises many intriguing questions that are addressed within the framework of elastic filamentary structures by modeling the stem close to the apex as a growing elastic rod.

基本上作者将这个缠绕在垂直树干上的藤蔓系统看作是垂直柱体上生长的弹性条。文章的意思是缠绕藤自身的曲率是藤蔓能够向上生长的重要因素。

Two kinds of methods to estimate the first derivative of rotating angle in the cracked section are presented.

针对J〓积分中的裂纹韧带曲率的计算问题，给出了两种简单的计算方法，即等截面梁估算法和椭圆边界变截面梁估算法。

A space without curvature is called a "flat space" or

没有曲率的空间成为''平坦空间''或

An experimental investigation of the combination of a long focal distance Bragg-Fresnel lens with a bimorph mirror is described.

描述了对长焦距布拉格-菲涅耳透镜与可变曲率半径反射镜组合所做的实验研究。

When a capillary tube, in whose inner hole an optical fiber has been fixed and whose axial deviation amount between an outer peripheral surface of the capillary tube and a core center of an end surface of the optical fiber is 1.5 mum or less, is inserted into the insertion portion of the thin tube and the end surface of the optical fiber is fixed at a position at which a distance of the end surface to a focal point position of the partially spherical lens becomes -40 mum or less, emission light has an emission light bend of 0.2 DEG or less with respect to the center axis of the thin tube.

当将光纤固定在内孔且外周面与光纤的端面的纤芯中心的轴偏移量在1.5μm以内的毛细管插入细管的插入部，并且将光纤的端面固定于部分球面透镜的焦点位置±40μm以内的距离的位置上时，出射光曲率为出射光相对细管中心轴在0.2°以内。

A blended wing-body, variable camber wings, and forebody strakes provided extra lift and control.

翼身融合，变曲率机翼，还有前机身边条翼提供了额外的升力和控制性能。

In chapter 5, the forked pipe blending surfaces modeling based on the envelope of the rolling ball is studied.

在这一章末，讨论了负高斯曲率的Bezier曲面在房顶曲面设计中的应用。
