Dear Rolf Mertig Professor:

I have calculate some feynman diagrams of elecweak model.Compairing

large gauge boson mass,the light quark momentum can be neglected,so

analytic results will be gotten.I expand B0,C0,D0 functions when

neglecting external momentum.But I found the results achieved by using

OneLoop function are different from the results achieved by hand.

So I chosed a very simple loop integration to check my results,and find

maybe OneLoop function is wrong.

I write a small function "OneLoopFPI" to imitate the processes of

calculations by hand Using feynman parameters method in common.I found

it give the same results with my previous results gotten by hand.

I send you a ps file about a very simple question dealing with OneLoop

and OneLoopFPI function.Maybe you can find where I was wrong.

Thanks for your attentions.
