This paper presents the general methods and process of panel die design in PRO/E environment. The design can be top- down and bottomup. The emphasis is on the design and analysis of die surfaces under the PRO/DIEFACE including extensions, extension ratio, spring back ,etc.

本文探讨在PRO／E环境下采用自顶向下和自底向上的方法进行覆盖件模具设计的技术、方法和过程，着重叙述利用PRO／DIEFACE进行模具接触面设计、分析和空间曲面处理的步骤，包括模具型面、工艺余料、法兰、拉深筋、弹复角的生成和成形度分析等。

The "U" length of well is measured from face of flange to end of well.

套管的"U"的长度是从法兰面到套管底测量的。

So I needed to wore a pair of high upper shoes with GTX outside material and V tread, and wore GTX dust coat, trousers with galluses, drip-dry underwear, a SUNTO watch in my wrist, at least a CASIO watch, and hung a GPS around my neck, and wore a jungle cap.

我还必须脚蹬一双 GTX 面 V 底的高帮鞋，外套是 GTX 风衣背带裤衬里衣物还需速干排汗的，手腕上戴 SUNTO ，最不济也要 CASIO ，脖子上吊一个 GPS ，头上戴一顶丛林帽。

Original height 146.5 meters, because the year long time makes decent, the peak flakes 10 meters, present height 136.5 meters; Foundation each length of side more than 230 rice, triangle surface ascent 52 degrees, tower floor space 52,900 square meters; The tower body builds by 2,300,000 stones, each stone average weight 2.5 tons, some amount to several dozens tons again; Some scholars estimated, if ships pyramid's stone material with the train, must use 600,000 freight cars approximately; If chisels garrulously these stones, the shop becomes a foot wide path, may circle an Earth week approximately.

原高146.5米，因年久风化，顶端剥落10米，现高136.5米；底座每边长230多米，三角面斜度52度，塔底面积5.29万平方米；塔身由230万块石头砌成，每块石头平均重2.5吨，有的重达几十吨；有学者估计，如果用火车装运金字塔的石料，大约要用60万节车皮；如果把这些石头凿碎，铺成一条一尺宽的道路，大约可以绕地球一周。

It is shown from the analysis results that in order to meet the requirement that the calculated geostrophic flow results can reflect the practical current profile structure, it is practicable to select the 700 m level as level of no motion in case of water depth greater than 700 m and to select the bottom boundary as level of no motion in calculating the geostrophic flow.

结果表明，为使计算结果可以反映实际的流速剖面结构，当水深大于700 m和小于700 m时可分别选取700 m层和底边界作为地转流动力计算零流面。

Dominant species were comprised of mainly micro- and meso-zooplankton species and planktonic larvae of benthos such as Parvocalanus crassirostris, Cirripedia nauplius, Oithona attenuata, Acrocalanus gibber, Nauplius, Bivalvia veliger, Copepodite, Oithona simplex and so on.

优势种主要是中小型种类和底栖动物的幼虫，如强额孔雀哲水蚤、蔓足类无节幼虫、细长腹剑水蚤、驼背隆哲水蚤、无节幼虫、双壳类面盘幼虫、桡足幼体、简长腹剑水蚤等。

Eliminate color, material and vamp style, the head form of a pair of shoes, bottom form, with form be most give colour and the position that grab an eye.

除去颜色、材料和鞋面式样，一双鞋的头形、底形、跟形是最出彩和抢眼的部位。

Lastly at the head of the board was the young poet who found a refuge from his labours of pedagogy and metaphysical inquisition in the convivial atmosphere of Socratic discussion, while to right and left of him were accommodated the flippant prognosticator, fresh from the hippodrome, and that vigilant wanderer, soiled by the dust of travel and combat and stained by the mire of an indelible dishonour, but from whose steadfast and constant heart no lure or peril or threat or degradation could ever efface the image of that voluptuous loveliness which the inspired pencil of Lafayette has limned for ages yet to come.

最后，桌子上首坐着位年轻诗人，他逃脱了教师这个行当和形而上学的审问，在苏格拉底式讨论的快活氛围中找到了避难所。右边是刚从赛马场来的油嘴滑舌的预言家，左边是那位谨慎的流浪者。他被旅途与厮打扬起的尘埃弄脏，又沾上了难以洗刷的不名誉的污点。然而他那坚定不移、忠贞不渝的心中却怀着妖娆的倩女面影，那是拉斐特在灵感触发下用那支画笔描绘下来的传世之作。任何诱惑、危险、威胁、屈辱，都无法消除。

The results indicate that the tempestite in the area has lots of rock types including clastic rocks, bioclastic limestones and volcaniclastic rocks. The cumulative probability plots have "high slope-multi-bouncing population-1 suspension population" pattern, multi segments pattern and "high slope 1 segment" pattern. The sedimentary structures include gutter cast, surface of scour, cut structure, graded bed, massive bedding, hummocky cross stratification, parallel bedding, ripples, contemporaneous deformation and Fugichnia. The grains distribution and sedimentary structures shier that the transportation medium is characterized by tractive current and gravity flow synchronously.

结果表明，该凹陷风暴沉积岩石类型丰富，包括各类碎屑岩、生物灰岩和火山碎屑岩粒度分布具有"高斜多跳悬式"、多段式和"高斜一段式"等多种样式沉积构造发育渠模、冲刷面、截切等底层面侵蚀构造和递变层理、块状层理、丘状层理、洼状层理、平行层理等构造，还发育有波痕和各种同生变形构造、生物逃逸构造等粒度分布和沉积构造反映出研究区兼有重力流和牵引流的水动力机制。

So a new type quarter-circularbreakwater is brought forward.As the same weight as semi-circular breakwater,quarter-circular breakwater bottom length is reduced to decrease jackstone.

为此，提出一种圆弧面(1/4圆)防波堤的新堤型，在与半圆型防波堤断面自重相近时，尽可能减窄底宽，从而减少大量抛石基床的数量。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
