In this dissertation the"Penalty"finite element method was employed to compute the velocity of the three-dimensional flow of power-law fluid in a profile die. In order to decrease the needed computer memory and raise the stability of numerical simulation, a set of decoupled methods such as PFEM, pseudo-body force method and transformation of momentum equation to the elliptic equation was developed to establish the general finite element equations to compute the distributions of velocity and viscoelastic stress of the three-dimensional viscoelastic flow of the Phan ThienTanner fluid in a profile die. During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory.

本文建立了求解挤出口模内幂律流体流动速度场的通用三维罚有限元模型；对于非线性粘弹性的Phan Thien-Tanner流体，为了降低模拟计算对计算机硬件的要求，并使模拟计算更加稳定，采用了一种去耦算法，包括罚有限元方法、拟体力方法和动量方程的椭圆类方程转化方法，并建立了求解速度场和粘弹性应力场的总体有限元方程；对于PTT流体的挤出胀大问题，提出了挤出胀大熔体口模内外分离模拟法，这样可以显著降低数值模拟对计算机硬件的要求。

During numerical simulation of the extrudate swell of the PTT fluid, the flow in the die and out of the die was analyzed separately, which demands less computer memory. The key techniques used in numerical simulation of the three-dimensional extrusion from dies such as decision of boundary conditions, creation of initial velocity field, selection of penalty factor, high Weissenberg number problem , regeneration of the free surface were studied in detail.

It has long been a mystery how enough matter can reach these cosmic gluttons to swell them to such large sizes.

足够的物质怎么才能靠近这些宇宙饭桶使它们膨胀到这么大只，长期以来一直成谜。

From the full choir when loud Hosannas rise, And swell the pomp of dreadful sacrifice, Amid that scene if some relenting eye Glance on the stone where our cold relics lie, Devotion's self shall steal a thought from Heav'n, One human tear shall drop and be forgiv'n.

当合唱团高声赞美上帝时，巨大的牺牲也随之而来，如果此时有一双同情的眼睛看到了我们冰冷的遗骨长眠之地，哪怕再虔诚的心，也会有一丝思绪离开天堂，世俗的泪水将会落下，并且得到宽恕。

From the full choir when loud Hosannas rise. And swell the pomp of dreadful sacrifice, Amid that scene if some relenting eye Glance on the stone where our cold relics lie.

穿着十来块钱的T恤+运动短裤，赤脚踩着五年前咬牙买下的运动鞋，同寝室的几个女生在校园里东晃晃西晃晃，消磨一整个下午～那时候人很单纯，是因为目标单纯。

Among these, there are 11 progressive jackpots that regularly swell into the millions of dollars, and almost the entire Real Series of multi-line video slots from RTG .

其中，有11 累积奖金，定期膨胀到数百万美元，几乎整个房地产系列多从发电机在线视频插槽。

The shoes also had a two-tone effect, and the swell of celestial voices in David Motion's "Buoyancy" on the soundtrack underscored the twisted religiosity. The bi-collar was a foretaste of what can only be described as a male bikini, which combined a bib front with what appeared to be a visible jockstrap (or maybe male garter belt?) and closed at the back like a waistcoat. Wags instantly dubbed the look "wedgie chic," but it was more disturbing than that—as if traditional concepts of masculinity had been turned inside out. Of course, this is something Miuccia's talked about for years, but it was still striking to see it rendered so graphically. Even more so when a couple of back-buttoning blouses walked past—male vulnerability wrapped up in a shirt.

这是本季男装戏谑趣味又颠覆传统的其一；仿似神职人员的double小领结及以两种色调呈现的皮鞋、再搭上伦敦著名作曲配乐家David Motion综合了圣乐与电子节拍的秀场主题曲&Buoyancy&，成功的带出Miuccia意欲传递给大家的矛盾和滑稽；更夸张傻眼的紧接而来：儿童使用的围兜（也很像中国古代女人的性感肚兜）配上男运动员专用的弹性下体护身、穿在合身的双领衬衫外，就活像是男性比基尼的外穿，然后转过身来，我们更看到，肚兜上衣的背后或交叉缕空的有如女人的性感马甲、或呈排扣有如女性内衣。

They told me to stay behind. They didn't want my knee to swell up on the plane.

他说，&他们叫我呆在后面，不希望我的膝盖肿起来。&

He told me his leg is not hurting, he's running well, the knee doesn't swell up.

他告诉我他的腿不疼了，膝盖感觉好多了。

"Sharp pain," he said."They told me to stay behind. They didn't want my knee to swell up on the plane."

&很痛，&阿水说，&他们叫我待在洛杉矶，他们不希望我的膝盖在飞机上变得更糟。&

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
