Is there curve showing the relation among drain current , drain-to-source voltage and w/l ratio in long channel MOSFET?
 

yes,but in general , is this curve look like the curve among drain current , drain-to-source voltage and gate-to-source voltage or not?
 

There's a non-linear relationship between this output characteristic set of curves and the gate-to-source voltage parameter, whereas the relationship with the w/l ratio is more or less linear. So, yes, the set of curves look a bit similar, but with non-constant distances between the individual curves in the former case, and (more or less) constant distances in the latter case.
