anticlastic

Then the paper explains the principle about crystal bending based on flexible hinge, the control about anticlastic distortion, the structure ensuring the fixing height between the input and output beam and the result on the finite element model about the surface of bending crystal.

说明了以柔性铰链为基础的弧矢压弯原理、压弯晶体鞍型形变的抑制、保证出射光与入射光高差固定的结构原理、压弯晶体衍射面面形误差的有限元分析结果；

The anticlastic curvature caused by bending is 1 700 times as long as the sagittal curvature, and the incident angle error is only 2.2 μ rad.

优化后晶体因压弯产生的鞍形曲率半径约为弧矢曲率半径的1700倍，造成的入射角误差为2.2μrad；

The result shows that the mechanical property and the durability of anticlastic dried mortar are suited to "six-resistance" enviroment in Qinghai plateau.
