折

Finally we study universal unfoldings correspondingto normal forms for the degenerate bifurcations of codimension two,codimension threeand codimension four.

最后研究了余维2退化、余维3退化和余维4退化分岔情况下相应规范形的普适开折。

The forces and moments on individual pile are not uniform because of the effects of group piles. The effects of KC number, water depth and current velocity on the coefficient of group piles are discussed.

由于群桩效应使得各组成桩的受力不均匀，通过试验研究，分析了群桩中各组成桩及群桩总体折减系数随KC数的变化、受水深及流速的影响。

The boy broke off a bit of wood and dropped it, with a dry leaf, into the box where the coin was before.

那男孩折了一小片木头，连同一片干树叶一起放进先前盛银币的盒子里。

AWARENESS: It's worst to suffer a collapses when you're not mentally prepared.

注意：最糟糕的是在没有心理准备的情况下进入了折翼。

Collarband, no occupiers whether round, square, acuminate or in ironing all keep it open deformation, had better be fixed shape and ironing, If there is a lead of iron wire, don't general plait, just after death, while it is still hot, with warm hands, gently press fold look like this will lead to live.

领口部位，无领者不论是圆形，尖形或方形，在整烫时都注意不要把它拉开变形，最好是固定形状再加以熨烫；如果是有领片的，不要将领褶线烫死，只要再烫以後，趁它还是温热的，用手翻折轻压，这样子领片看起来会比较活。

This method overcome the problems of many supposition conditions in theory and difficulty in searching critical slip surface in 3D limiting equilibrium analysis; It uses the 3D FEM\'s stress field directly, differs from the practical value of 3D FEM strength reduction method used hypothesized load, and differs from the characteristic of the FEM with limiting equilibrium theory still to need to divide the columniation, and suppose the critical slip surface in advance.

该方法克服了三维极限平衡分析方法在理论上引入较多假设条件，且搜索临界滑裂面困难的问题；它直接采用三维有限元应力场，不同于三维有限元强度折减法基于虚拟荷载上得出的实用价值；同时异于沿用极限平衡理论的有限元法仍需要进行条柱划分，并事先假设滑裂面形状及位置的缺点。

The experimental results provide technical support for this kinds of combustor design and development.

该研究结果为折流燃烧室的设计提供了有益的参考。

The simulation results show that the rod baffles placed vertically and horizontally in the unit duct continuously shear and comminute the streamlines of the flow when the fluid crosses over the rod-baffles, change the fluid flow directions, and result in the disruption of the continuity and stability of the fluid. The disturbing flow can promote the fluid turbulent intensity and effectively enhance the heat transfer.

结果表明，纵横交错布置的折流杆在单元流道中不断分割和剪切流道内流体，其扰流作用促进了流体湍流，减薄了液体边界层，减小了对流换热热阻，因而有效地提高了流体的对流换热强度。

Using the method of optimal efficiency and maximal quantity of refrigerating output, a thermoelectricity refrigeration system commix with compress refrigeration is designed.

本文对塑料片低温对折机功率热电制冷系统的设计方案进行了探讨。

Using the method of optimal efficiency and maximal quantity of refrigerating output , a thermoelectricity refrigeration system commix with compress refrigeration is designed .

为满足塑料低温对折机快速降温和低温操作要求，采用热电制冷的最佳效率和最大冷量两种工况设计计算，研制了机械压缩式和热电制冷相结合的混合制冷系统，并提供了试验数据。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
