Problems occurring in physically important non-trivial examples of loop calculations are discussed. A procedure of deriving expansions of two-loop self-energy diagrams with diierent masses is constructed. The cases of small and large external momentum are considered. The coeecients of the expansions are calculated analytically. Comparison with numerical(More)
