请问谁知道国际光学图纸这个标注什么意思？
Surface quality: 60-40 S'~o,`xy
R6 XuA(5
The surface marked R1 is conic surface (aspheric surface) with folowing equation: T2 ?HRx
Y^2=2 R1_0 X - (1- e^2) X^2 where R1_0 = -10.700B0.010 & e^2 = 0.060B0.003 ~#\i!I;RY}
PC c|}*b
The surface marked R2 is conic surface (aspheric surface) with folowing equation: aKF*FFX
Y^2=2 R2_0 X - (1- e^2) X^2 where R2_0 = 13.698B0.013 & e^2 = 0.106B0.003 zm9TvoC%}

里面的半径公差给了，但是咱们国家标准一般使用光圈来表示，如何换算呢？ 1gO2C $

下面的小格子里都是什么意思啊 "%8A :^1
