摘要	The residue Coulomb interaction (RCI), which affects the result of symmetry-energy coefficient of neutronrich nucleus in isobaric yield ratio (IYR) method, is difficult to be determined. Four RCI approximations are investigated: (i) The M1-RCI adopting the a(c)/T (the ratio of Coulomb energy coefficient to temperature) determined from the IYR of mirror-nucleus fragments; (ii) The M2-RCI by fitting the difference between IYRs; (iii) The M3-RCI adopting the standard Coulomb energy at a temperature T = 2 MeV; and (iv) Neglecting the RCI among isobars. The M1-, M2- and M3-RCI are no larger than 0.4. In particular, the M2-RCI is very close to zero. The effects of RCI in a(sym)/T of fragment are also studied. The M1- and M4-a(sym)/T are found to be the lower and upper limitations of a(sym)/T, respectively. The M2-a(sym)/T overlaps the M4-a(sym)/T, which indicates that the M2-RCI is negligible in the IYR method, and the RCI among the three isobars can be neglected. The relative consistent low values of M3-a(sym)/T (7.5 +/- 2.5) are found in very neutron-rich isobars.
