起皱的

And discusses the wrinkle of metal board workpieces shape process,the adjustable Method of point body height,the better design method on point body parameters,the CMM/CAD/CAM in flexible automation system on multipoint die .

介绍了多点冲模的原理，探讨了多点冲模成形过程板料起皱、点销高度的控制调整方法、点销相关参数的确定、冲压柔性自动化系统中CMM /CAD/CAM系统集成等问题。

In this paper, the deep drawing of TA0 titanium hemispherical part is studied by numerical simulation and experiment method.

以TA0薄壁半球形零件冷拉深成形为研究对象，采用数值模拟与试验研究相结合的手段，在研究该拉伸成形过程中零件的应变及壁厚分布规律及组织演变规律的基础上，对破裂、起皱缺陷位置进行了预测。

The typical failures are hulking and fracture, and both of them are problems of instability.

成形过程中常见的缺陷是起皱和破裂，这两种缺陷的产生都和管的失稳有关。

The results show that the medial surface wrinkling and the lateral surface unstability are the main failure form of the thin-wall stainless steel tubes in cold bending forming.

结果表明，薄壁不锈钢管件弯曲冷成形的主要失效形式是内侧部分的起皱和外侧部分的失稳。

He fumbled in his pocket,re-membering the piece of crumpled paper the man had handed to him

他记起刚才在黑暗的途中，那弟兄给他一团折皱的硬纸，说是那男的手

The picture of the men coming to nurse her was as lifeless as the nerves in her back where the skin buckled like a washboard.

那些男人来吃她奶水的影像，正如她背部的神经一般了无生机──她背部的皮肤像洗衣板似的起皱。

Yes, there would be a day when his face would be wrinkled and wizen , his eyes dim and colourless, the grace of his figure broke and deformed.

对，将来总有一天他的脸庞会起皱和萎缩，他的眼睛会朦胧无光，他那优雅的躯体会屈曲变形。

The system can be used to both predict the wrinkling phenomena and analyze the bending process.

5塑性变形能与起皱能的比值随着管弯曲成形过程的进行是不断波动变化的，但存在一个最大值。

The internal wrinkling and the forming limit are the key problems urgently to be solved for research and development of the process.

内缘失稳起皱及相关的成形极限是这一先进塑性加工过程研究中存在的迫切需要解决的关键问题。

"Cellulose acetate is the second largest sort among cellulose fiber only next to gum fiber. Cellulose acetate's main raw materials main include wood pulp and cotton flannel that are all reproductive.

醋酸长丝在化学纤维中最酷似真丝，光泽柔和，手感柔软滑爽，不易受水浸湿，回潮率低，弹性好，不易起皱，具有良好的悬垂性与热塑性，染色鲜艳，是优良的纺织原料。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
