基于平面塑性变形的特点，提出了平面剪切变形线的概念，从而为塑性理论平面问题补充了一个新概念。

In this paper, the concept of a shear deforming line that is based on the properties of 2-dimension plastic deformation is presented.

在上面这张照片中，这轮因大气折射而显得有些变形的超级满月，紧挨着地平线，就好像正在美国波士顿市上空冉冉升起。

Seen here, the near perigee Full Moon still hugs the horizon, distorted by atmospheric refraction as it rises over Boston, Massachusetts, USA.

勾选框的测量表明，变形参数将解决使用测量线(见下文)。

The measure tick-boxes indicate which distortion parameters will be solved using measurement lines (see below).
