He explained that this name was part of the title of a silly fairy tale, called The Three Princes of Serendip: as their highnesses traveled, they were always making discoveries, by accidents and sagacity, of things which they were not in quest of ... One of the most remarkable instances of this accidental sagacity (for you must observe that no discovery of a thing you are looking for, comes under this description) was of my Lord Shaftsbury , who happening to dine at Lord Chancellor Clarendon's , found out the marriage of the Duke of York and Mrs. Hyde , by the respect with which her mother treated her at table.

他解释说这个名字是"一个朴素的神话故事，称作 The Three Princes of Serendip的童话"的名字的一部分：当这些殿下旅行时，他们总是通过意外和精明地发现他们并没有寻求的东西…这种 accidental sagacity的最著名的实例你必须注意到根据这种描述你没有发现你正在寻找的东西）是我的沙夫茨伯里老爷，偶然在钱塞勒·克拉伦登老爷处用餐时，发现了约克的杜克同海德夫人的婚事是根据她的母亲在吃饭款待她时发现的。

Never be tempted by any dangerous sport cherished by Westerners, such as climbing cliffs or mountains using ropes, even though you are armed with the spirit of the current theory of Three talks and three representations.

不要被西方人所说服而去参加危险的运动，像是攀岩或只用绳子爬山，即使你有那样的精神以及相信"three talks and three representations"（俚语，Google下吧），你并不像西方人那样吃很多的肉和牛奶，你的身体也没有那么见状。

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. 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.

中文题名聚合物异型材口模挤出三维流动研究副题名外文题名 Study on three-dimensional flow of polymer melts during the process of profile extrusion from dies 论文作者涂志刚导师柳和生包忠诩教授学科专业材料加工工程研究领域\研究方向学位级别博士学位授予单位南昌大学学位授予日期2001 论文页码总数148页关键词挤出成型聚合物材料挤出口模聚合物异型材馆藏号BSLW /2003 /TQ320 /9 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。
