摘　　要：分析了弧矢聚焦晶体弯曲原理及柔性铰链运动方程 ,阐述了弧矢聚焦晶体柔性铰链压弯机构的原理 ,同时提出了抑制子午形变的有效方法。该压弯机构在 5— 2 0keV能量扫描范围内 ,弧矢聚焦比为 3:1,聚焦曲率相对误差 <0 .75 % ,聚焦光斑弥散为 2 5 % ,在 10keV时聚焦面形误差 <2”。The bending principle of sagittal focusing crystal and the movement equation of flexible hinges are analyzed, and the principle of bending structure based on flexible hinges for sagittal focusing crystal is also elaborated. To restrain meridional deformation, an effective method is put forward. Within the arrange of 5-20keV, the sagittal focusing ratio of the bending structure is 3:1, the relative error of focusing curvature is less than 0.75%, and the focusing facula dispersion is 25%. At 10keV the error of focusing surface deformation is less than 2'.
