  Along with masses of pion and sigma meson modes, their dissociation into
quark medium provide a detail spectral structures of the chiral partners.
Present article has studied a finite size effect on that detail structure of
chiral partners by using the framework of Nambu-Jona-Lasinio model. Through
this dissociation mechanism, their diffusions and conductions are also studied.
The masses, widths, diffusion coefficients, conductivities of chiral partners
are merged at different temperatures in restore phase of chiral symmetry, but
merging points of all are shifted in lower temperature, when one introduce
finite size effect into the picture. The strengths of diffusions and
conductions are also reduced due to finite size consideration.
