请问谁知道国际光学图纸这个标注什么意思？
Surface quality: 60-40 HTtGpTsF
S1^Mw;?P
The surface marked R1 is conic surface (aspheric surface) with folowing equation: C4 S D
Y^2=2 R1_0 X - (1- e^2) X^2 where R1_0 = -10.700B0.010 & e^2 = 0.060B0.003 YV _I-l0
{;(g[H=q;

Y^2=2 R2_0 X - (1- e^2) X^2 where R2_0 = 13.698B0.013 & e^2 = 0.106B0.003 /CQQ ^/

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？ Kg0\Pvg8?T
{msB+n~WZ
下面的小格子里都是什么意思啊 q$2ta G}
