请问谁知道国际光学图纸这个标注什么意思？
Surface quality: 60-40 m G+=0Rn^
gC_KT,=H;
The surface marked R1 is conic surface (aspheric surface) with folowing equation: <29K!
[
Y^2=2 R1_0 X - (1- e^2) X^2 where R1_0 = -10.700B0.010 & e^2 = 0.060B0.003 e:rbyzf#

The surface marked R2 is conic surface (aspheric surface) with folowing equation: P%!=Rj^ 2m
Y^2=2 R2_0 X - (1- e^2) X^2 where R2_0 = 13.698B0.013 & e^2 = 0.106B0.003 /wP2Wnq$

还有下面这个图 l<7SB5

[attachment=34561] $++ O@ C5
*!dA/sid
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？ %E [HMq<H
cVr+Wp7K#|
下面的小格子里都是什么意思啊 :s-9@Yl|
