x is specified as the radius sounds like x = radius that is the bone in one's arm.

x is specified for the radius sounds like x is a measurement for the length ( radius ).Emotion: smile.

Just take a guess, don't laugh too loud if both are wrongEmotion: smile

Students: Are you brave enough to let our tutors analyse your pronunciation?
Sorry, bad example. How about;
x is specified as the aperture number
or
x is specified for the aperture number
Mike you asked which is sentence is more appropriate to use ?
Then I would choose ' for '
Students: We have free audio pronunciation exercises.
Why I always made a typo in a post Emotion: sad
I would probably say "as," myself, but "for" sounds equally good. I just wouldn't use it automatically.
Thanks whl626 and Kit,
Last week I advised a student to use 'as', now I feel better.
Thank you both for your help.
