本文按材料的幂强化模型推导了工程中板材塑性弯卷时弯板力矩的计算公式。
In this paper, the calculating formula of bending moment plastically rolling plates was developed for power-hardening materials.
通过工艺分析，给出了板料预弯卷圆压形工序中压形模具的设计思想、结构和工作过程的设计要点。
Through analyzing the process, the author has offered the idea about designing the compression mold in sheet pre-curved rolling process, key points in the structure and working procedures;
这个疯人院的头子有着油亮的头顶，弯卷的领带，一本正经的英腔，以及“能用道德将法律、秩序和医务融合起来”的信念。
The head man—in every sense—of the asylum has a shiny dome, a bow tie, a prissified English accent, and a belief in “the moral fusion between law and order and clinical care.”
到了好莱坞大道后，我在葡萄藤站拐了个弯，骑了一会儿就在我一个大学同学推荐的卡特斯玉米卷小摊前停下，买了三个墨西哥玉米卷，依次是肉丝卷饼、嫩羊肉卷饼和辣辣的艾尔巴特卷饼。
Once there, I made a turn on Vine for a quick stop at the Cactus taco stand, recommended by a college friend, for three tacos, one each of carnitas, moist goat and spicy al pastor.

畸变屈曲作为控制冷弯薄壁卷边槽钢柱承载力的重要模式之一，正逐步受到国内外研究人员的重视。
As one of the strength-governing modes for cold-formed channel columns, distortional buckling is receiving more attentions.
而现行冷弯型钢设计规范GB 50018- 2002采用有效截面法计算受弯构件的屈曲荷载并没有考虑卷边角度的影响，不能合理的进行斜卷边Z型檩条的屈曲荷载设计。
But the current specification GB50018-2002 does not consider the effect of lip inclination, hence, it cannot be effectively used in designing inclined lipped Z-section purlins.
