Pro Engineer介绍

十五、Pro／INTERFACE

Pro/INTERFACE是一个完整的工业标准数据传输系统，提供 Pro/Engineer与其它设计自动化系统之间的各种标准数据交换格式．它可用于 Pro/ENGINEER几何的输入和输出。剖面可以参数化并被构造 Pro/ENGINEER内的任意特征种类。

1． 二维和三维图形：Pro/INTERFACE提供了将2D和3D图形通过 IGES4．0或 SET输入到 Pro/ENGINEER的绘图模式里的能力，输入后，正常制图功能都是有效的。

2． 三维线框图形：Pro/INTERFACE提供了将3D线框几何体通过 IGES4．0或 SET 输入到 Pro/ENGINEER内的能力，该线框体能被用于生成全参数化，以特征为基础的实体模型。如果需要，可以复盖到非参数化的实体模型上。

3． 任意形状曲面：Pro/INTERFACE提供了通过 IGES4．0或 SET将一个或更多的任意形状曲面输入到 Pro/ENGINEER内的能力。一旦输入后，这些面可以被偏置和缝合在一起，及被其它曲面剪裁，它们也可以被用于构造一个实体模型(见 Pro/SURFACE有关详细描述)。

4． 三维表面模型：Pro/INTERFACE提供了通过 IGES4．0或 SET将部分表面或整个表面线框模型输入到 Pro/ENGINEER内的能力。在 Pro/ENGINEER内．如果有遗漏表面可以加上，并且整个表面模型也可以复盖到一个非参数化的实体模型上。覆盖到非参数化实体模型上的表面可以作为一个“单一特征”。这样用户就可以将所有参数化特征附加到这“单一特征”上，当然该特征也能象其它任何 Pro/

ENGINEER修改。

数据交换功能包括：

1． SLA：用于将3D模型信息输出到生产工作台。

2． RENDER：用于将3D模型信息输出到著色程序。

3． DXF：用于输入和输出那些支持 DXF格式文件系统的2D信息。

4． NEUTRAL：用于输出符合 Pro/ENGINEER中间文件格式的特征、零件、部公差信息。

5． IGES：用于输出符合 IGES4．0标准的2D图形和3D模型(包括零件和部件)。

6． PATRAN Geom；用于输出符合 PATRAN中间文件格式的零件几何体数据。

7． IGES128：用于输出零件几何体(注：除非特殊需求规定，将无效)。

8． SUPERTA BGeom：输出符合用于输入列 SUPERTAB的 UNIVERSAL文件格式的几何体。

9． SET：用于输入符合 VDA标准的 Pro/ENGINEER模型。

十六、Pro／LANGUAGE

Pro/LANCUAGE是一个选件模块，为 Pro/ENGINEER的菜单及求助说明提供语言翻译功能，目前可支援的其他语盲包括德文及日文(Kanji)。除此之外，所有客户在支援日文(Kanji)字符及日文键盘作业之硬件平台上，均可以用日文为 Pro/ENGINEER的工程图加上附注或文字。同时，德文版及日文版的 Pro/ENGINEER用户基本 *** 作说明书．亦一并提供。

十七、Pro／LIBRARYACCESS

Pro/LIBRARYACCESS提供了一个超过2万个通用标准零件和特征的扩展库，用户可以很方便地从菜单里拾取任意工业标准特征或零件，并将它们揉台进零件或部件的设计中，使用更方便、快速、并能提高生产力。

1． 标准零件包括：方形和六角形螺帽、平面垫圈、d簧垫圈、半月销、机制螺母，内藏凸台和止动螺钉，大小固 铆钉，开口销和叉杆销等等。

2． 标准特征包括：孔、槽、凸台、镗孔，同轴凸台，通风格栅．金属片偏置，金属片弯管特征，管状特征等等。

十八、Pro／MESH

Pro/MESH提供了实体模型和薄壁模型的有限元网格自动生成能力。也就是它自动地将实体模型划分成有限元素，以便有限元分析用，所有参数化应力和范围条件可直接在实体模型上指定，即允许设计者定义参数化载荷和边界条件，并自动生成四边形或三角形实体网格。载荷/边界条件与网格都直接与基础设计模型相关联，并能象设计时一样进行交互式修改。

Pro/MESH包括：

1． 自动生成四面体单元和三角形薄壳单元(单元厚度参数由模型厚度决定)

2． 参数化定义网格

3． 载荷与边界条件是参数化的，并被直接应用到几何体上(包括所有和局部区域)。同时也可连接到设计参数里。

4． 支持作用于面的对流约束

5． 支持固定点上的瞬时载荷约束

十九、Pro／MOLDESIGN

Pro/MOL DESIGN模块用于设计模具部件和模板组装，它包括如下功能：

1． 采用参照设计模型的方法，自动生成模具型腔几何体。

2． 对单一、多面类似或者多面不同的型腔，采用 Pro/ENGINEER的组装命令及花样组来定出型腔。

3． 对复杂的多面/注模，提供 Slider/CAMMED移动功能。

4． 用不同的缩减补偿方式，修改造型几何体。

5． 在模拟过程，采用干扰核查的方法支定度及模似模具开口及 Molding Ejection Sequence.

6． 备有 AC Technology的 C—Flow/EZ分析软件，提供空腔冲填及 AIR TRAPPING模拟、 Front、ram速度、weld线及流体速度(Flow Velocity)。

7． 直接取得 Pertinent模具设计工程的信息，包括冲填器皿及型腔表面积等信息。

8． 可生成摸具的特定功能，包括浇口(Sprue)、浇道(Runner)、浇槽(Gates)、冷凝线(cooling line)及分离线。

9． Pro/LIBARARY亦有提供与 Pro/MOLDESIGN使用的功能，包括标准化的摸具组装及元件。

二十、Pro／MANUFACTURING

Pro/MANUFACTURING将产生生产过程规划．刀路轨迹并能根据用户需要产生的生产规划做出时间上及价格成本上的估计。Pro/MANUFACTURING将生产过程生产规划与设计造型连接起来，所以任何在设计上的改变，软件也能自动地将已做过的生产上的程序和资料也自动地重新产生过，而无需用户自行修。它将具备完整关联性的Pro/ENGINEER产品线延伸至加工制造的工作环境里。它容许用户采用参数化的方法去定义数值控制(NC)工具路径，赁此才可将Pro/ENGINEER生成的模型进行加工。这些信息接着作后期处理，产生驱动NC器件所需的编码。

Pro/MANUFACTURING为下列机器 *** 作产生自动化的工具路径：

1． 铣削加工(Mitting)

2． 车削加工(Turning)

3． 线体电子释放机械技术

4． 钻床加工(Dritting)

二十一、Pro／NC- CHECK

1．Pro/NC-CHECK提供图型工具．用以对铣削加工及钻床加工 *** 作所产生的物料，作模拟清除。Pro/NC-CHECK内选定的工具．会依照 Pro/MANUFACTURING定义的切割路径移动，用户亦可以清楚看到物料清除的进度。加工制造组件以阴影显示，装组线上各个组件可以由用户设定不同的颜色。它亦让用户可以在整个加工制造过程，定义夹层平面(Clipping Plane)特定的深度。夹层平面(Clipping Plane)对物料清除摸拟过程提供纵切面的阅视功能。这项独一无异的功能．再加上颜色的设定，选定工具路径、内置参考模型、工具及任何夹具(Fixture)均能一目了然．不生混淆。此外，Pro/NC- CHECK能让用户对工具及夹具(Fixture)进行快速验证及评佑。从而防止严重的损失。

1、主干句：these systems emit no heat-trapping carbon dioxide or other air pollutants and need no water for cooling.

— 主语：these systems：这些系统

— 并列谓语部分 ——

* emit no heat-trapping carbon dioxide or other air pollutants and 不放射出吸热的二氧化碳或者其他空气污染物

* need no water for cooling. 无需冷却水。

2、附加成分：With a moderate to fairly high net energy yield 对相当高纯的能量产额具有一种稳定性的情况下

* 核心词：a moderate

* 后置定语：to fairly high net energy yield （修饰 moderate，）

其中——核心词是energy yield，形容词net 是它的定语（即纯能量产额），副词high 修饰形容词 net（即高度纯的），另一个副词修饰fairly， 修饰副词 high（即非常高度地），整个意思是“相当高纯的能量产额”。

Hanover Square

追忆似水年华

Can it really be sixty-two years ago that I first saw you?

It is truly a lifetime, I know. But as I gaze into your eyes now, it seems like only yesterday that I first saw you, in that small café in Hanover Square.

From the moment I saw you smile, as you opened the door for that young mother and her newborn baby. I knew. I knew that I wanted to share the rest of my life with you.

Hanover Square 追忆似水年华

I still think of how foolish I must have looked, as I gazed at you, that first time. I remember watching you intently, as you took off your hat and loosely shook your short dark hair with your fingers. I felt myself becoming immersed in your every detail, as you placed your hat on the table and cupped your hands around the hot cup of tea, gently blowing the steam away with your pouted lips.

From that moment, everything seemed to make perfect sense to me. The people in the café and the busy street outside all disappeared into a hazy blur. All I could see was you.

Hanover Square 追忆似水年华

All through my life I have relived that very first day. Many, many times I have sat and thought about that the first day, and how for a few fleeting moments I am there, feeling again what is like to know true love for the very first time. It pleases me that I can still have those feelings now after all those years, and I know I will always have them to comfort me.

Hanover Square 追忆似水年华

Not even as I shook and trembled uncontrollably in the trenches, did I forget your face. I would sit huddled into the wet mud, terrified, as the hails of bullets and mortars crashed down around me. I would clutch my rifle tightly to my heart, and think again of that very first day we met. I would cry out in fear, as the noise of war beat down around me. But, as I thought of you and saw you smiling back at me, everything around me would be become silent, and I would be with you again for a few precious moments, far from the death and destruction. It would not be until I opened my eyes once again, that I would see and hear the carnage of the war around me.

Hanover Square 追忆似水年华

I cannot tell you how strong my love for you was back then, when I returned to you on leave in the September, feeling battered, bruised and fragile. We held each other so tight I thought we would burst. I asked you to marry me the very same day and I whooped with joy when you looked deep into my eyes and said "yes" to being my bride.

I'm looking at our wedding photo now, the one on our dressing table, next to your jewelry box. I think of how young and innocent we were back then. I remember being on the church steps grinning like a Cheshire cat, when you said how dashing and handsome I looked in my uniform. The photo is old and faded now, but when I look at it, I only see the bright vibrant colors of our youth. I can still remember every detail of the pretty wedding dress your mother made for you, with its fine delicate lace and pretty pearls. If I concentrate hard enough, I can smell the sweetness of your wedding bouquet as you held it so proudly for everyone to see.

Hanover Square 追忆似水年华

I remember being so over enjoyed, when a year later, you gently held my hand to your waist and whispered in my ear that we were going to be a family.

I know both our children love you dearlythey are outside the door now, waiting.

Do you remember how I panicked like a mad man when Jonathon was born? I can still picture you laughing and smiling at me now, as I clumsily held him for the very first time in my arms. I watched as your laughter faded into tears, as I stared at him and cried my own tears of joy.

Hanover Square 追忆似水年华

Sarah and Tom arrived this morning with little Tessie. Can you remember how we both hugged each other tightly when we saw our tiny granddaughter for the first time? I can't believe she will be eight next month. I am trying not to cry, my love, as I tell you how beautiful she looks today in her pretty dress and red shiny shoes, she reminds me so much of you that first day we met. She has her hair cut short now, just like yours was all those years ago. When I met her at the door her smile wrapped around me like a warm glove, just like yours used to do, my darling.

Hanover Square 追忆似水年华

I know you are tired, my dear, and I must let you go. But I love you so much it hurts to do so.

As we grew old together, I would tease you that you had not changed since we first met. But it is true, my darling. I do not see the wrinkles and grey hair that other people see. When I look at you now, I only see your sweet tender lips and youthful sparkling eyes as we sat and had our first picnic next to that small stream, and chased each other around that big old oak tree. I remember wishing those first few days together would last forever. Do you remember how exciting and wonderful those days were?

Hanover Square 追忆似水年华

I must go now, my darling. Our children are waiting outside. They want to say goodbye to you.

I wipe the tears away from my eyes and bend my frail old legs down to the floor, so that I can kneel beside you. I lean close to you and take hold of your hand and kiss your tender lips for the very last time.

Sleep peacefully my dear.

Hanover Square 追忆似水年华

I am sad that you had to leave me, but please don't worry. I am content, knowing I will be with you soon. I am too old and too empty now to live much longer without you.

I know it won't be long before we meet again in that small café in Hanover Square.

Goodbye, my darling wife.

The barn was very large. It was very old. It smelled of hay and it smelled of manure. It smelled of the perspiration of tired horses and the wonderful sweet breath of patient cows. It often had a sort of peaceful smell -- as though nothing bad could happen ever again in the world. It smelled of grain and of harness dressing and of axle grease and of rubber boots and of new rope. And whenever the cat was given a fish-head to eat, the barn would smell of fish. But mostly it smelled of hay, for there was always hay in the great loft up overhead. And there was always hay being pitched down to the cows and the horses and the sheep.

The barn was pleasantly warm in winter when the animals spent most of their time indoors, and it was pleasantly cool in summer when the big doors stood wide open to the breeze.

"Salutations!" said the voice.

Wilbur jumped to his feet. "Salu-what?" he cried.

"Salutations!" said the voice.

"What are they, and where are you?" screamed Wilbur. "Please, please, tell me where you are. And what are salutations?"

"Salutations are greetings," said the voice. "When I say 'salutations,' it's just my fancy way of saying hello or good morning. Actually, it's a silly expression, and I am surprised that I used it at all. As for my whereabouts, that's easy. Look up here in the corner of the doorway! Here I am. Look, I'm waving!"

At last Wilbur saw the creature that had spoken to him in such a kindly way. Stretched across the upper part of the doorway was a big spider web, and hanging from the top of the web, head down, was a gray large spider. She was about the size of a gumdrop. She had eight legs, and she was waving one of them at Wilbur in friendly greeting. "See me now?" she asked.

"Oh, yes indeed," said Wilbur. "Yes indeed! How are you? Good morning! Salutations! Very pleased to meet you. What is your name, please? May I have your name?"

"My name," said the spider," is Charlotte."

"Charlotte what?" asked Wilbur, eagerly.

"Charlotte A. Cavatica. But just call me Charlotte."

"I think you're beautiful," said Wilbur.

Wilbur was now the center of attraction on the farm. Good food and regular hours were showing results: Wilbur was a pig any man would be proud of. One day more than a hundred people came to stand at his yard and admire him. Charlotte had written the word RADIANT, and Wilbur really looked radiant as he stood in the golden sunlight. Ever since the spider had befriended him, he had done his best to live up to his reputation. When Charlotte's web said SOME PIG, Wilbur had tried hard to look like some pig. When Charlotte's web said TERRIFIC, Wilbur had tried to look terrific. And now that the web said RADIANT, he did everything possible to make himself glow.

It is not easy to look radiant, but Wilbur threw himself into it with a will. He would turn his head slightly and blink his long eyelashes. Then he would breathe deeply. And when his audience grew bored, he would spring into the air and do a back flip with a half twist. At this the crowd would yell and cheer. "How's that for a pig?" Mr. Zuckerman would ask, well pleased with himself. "That pig is radiant."

Your future is assured. You will live, secure and safe, Wilbur. Nothing can harm you now. These autumn days will shorten and grow cold. The leaves will shake loose from the trees and fall. Christmas will come, then the snows of winter. You will live to enjoy the beauty of the frozen world. Winter will pass, the days will lengthen, the ice will melt in the pasture pond. Then song sparrow will return and sing, the frogs will awake, the warm wind will blow again. All these sights and sounds and smells will be yours to enjoy, Wilbur--this lovely world, these precious days..."

Charlotte stopped. a moment later a tear came to Wilbur's eyes. "Oh, Charlotte," he said.

"Why did you do all this for me?" he asked. "I don't deserve it. I've never done anything for you."

"You have been my friend," replied Charlotte. "That in itself is a tremendous thing. I wove my webs for you because I liked you. After all, what's a life, anyway? We're born, we live a little while, we die. A spider's life can't help being something of a mess, with all this trapping and eating flies. By helping you, perhaps I was trying to lift up my life a trifle. Heaven knows anyone's life can stand a little of that."

"Salutations!" it said. "I'm up here."

"So am I," said another tiny voice.

"So am I,"said a third voice. "Three of us are staying. We like this place, and we like you."

Wilbur looked up. At the top of the doorway three small webs were being constructed. On each web, working busily was one of Charlotte's daughters.

"Can I take this to mean," asked Wilbur, "that you have definitely decided to live here in the barn cellar, and that I am going to have three friends?"

"You can indeed," said the spiders.

"What are your names, please?" asked Wilbur, trembling with joy.

"I'll tell you my name," replied the first little spider,if you'll tell me why you are trembling."

"I'm trembling with joy," said Wilbur

"Then my name is Joy," said the first spider.

"What was my mother's middle initial?" asked the second spider.

"A," said Wilbur.

"Then my name is Aranea," said the spider.

"What about me? "asked the third spider. "Will you just pick out a nice sensible name for me--something not too long, not too fancy, and not too dumb?"

Wilbur thought hard.

"Nellie?" he suggested.

"Fine, I like it," said the third spider."You may call me Nellie."
