【摘要】 对用宽度变化的镜子压制椭圆柱面和抛物柱面的方法进行了系统的讨论 ,给出了梯形镜的宽度变化公式。用矩形板和梯形板压制了椭圆柱面形镜与进行了摩擦力修正的压弯公式计算值相符合 ;结果表明 ,使用梯形镜可以提高压弯精度。更多还原

【Abstract】 The bending methods for elliptic and parabolic figure with variable-width mirror were discussed and the formula of variable-width for ladder-shaped mirrors was given. The rectangular and ladder-shaped mirrors were elliptically bent. The bending formula was modified by comparing measured result with calculated one.更多还原
