请问谁知道国际光学图纸这个标注什么意思？
Surface quality: 60-40 sV Z}nq{

The surface marked R1 is conic surface (aspheric surface) with folowing equation: JqH.Qn Kcv
Y^2=2 R1_0 X - (1- e^2) X^2 where R1_0 = -10.700B0.010 & e^2 = 0.060B0.003 \ [hrG?A

还有下面这个图 5"Xo R)

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？

下面的小格子里都是什么意思啊 <P
