“折纸工程师”通过沿着固定的折痕折叠刚性材料薄片来构建各种各样的物体。
"Origami engineers" build a variety of objects by folding sheets of rigid material along set creases.
在折纸艺术中，艺术家会在一张纸上用精确的折叠和折痕来创造一个动物或形状。
In the art of origami, the artist would create a single animal or shape from a sheet of paper using precise folds and creases.
他们用数学来证明他们使用的折痕模式能够真的造出他们正在折叠的形状，并取得了一定进展。
They've begun making progress on the mathematics to prove that the shapes they're folding can actually be made with the crease patterns they're using.
“从数学上来说，甚至还不清楚该问什么样的问题。”埃里克谈及处于折叠研究前沿的曲线折痕时说道。
"Mathematically, it's not even clear what the right questions to ask are," Erik says of the curved creases, which are at the cutting edge of folding research.
折痕角度越大，吸热表面积越大，也可以折叠的更快。
Wider hinges also fold faster, because there is more surface area to absorb energy.
板子上的黑色粗线条会比其他部分吸收更多的热量，这样塑料板就会紧缩——产生折痕，继而轻松折叠成三维模型。
The bold black lines absorb more energy than the rest of the material, causing the plastic to contract — creating a hinge that folds the sheets into 3-d shapes.
“你也可以在塑料板的任一表面画出线条，”迪克说，“那样折痕沿着不同方向进行折叠，你就能创造出更多复杂的结构。” 研究员推出一种电脑数据模型来解释整个工作过程。
"You can also pattern the lines on either side of the material," Dickey says, "which causes the hinges to fold in different directions.
打开一个折痕，折叠纸的质地和降低饱和度。
再次打开它，折叠和新闻中心都将边缘，然后折沿折痕它的第一个。
Open it up again, fold and press both edges into the center and then fold it along the first crease.
沿着折痕折叠好一个内盒。
