While it's easy to see matter bending light - just look through a prism - it's rare to find light bending matter.
只要通过棱镜就可以很容易地看到弯曲光线的物质，而这里却是罕见的弯曲物质的光线。

The least bending energy method takes the bending energy as the objective function, and gets the reasonable cable forces by seeking the least bending energy.
最小弯曲能量法以结构的弯曲应变能为目标函数，通过求出最小弯曲能量来求得合理索力。

B. in a later chapter, hollow plate the smallest bending radius is 175 times of its thickness, can only cold bending, hot bending.
