%X About the one-dimensional Heisenberg ferromagnetics chain with bond alternation,research results show,in first-order approximation,that (1) magnon gap solitons (with the vibrating frequency lying in the gap between magnon frequency band) and resonant kinks (with the vibrating frequency lying in the magnon frequency band) are found; (2) an instrinsic localized mode (with the vibrating frequency being above the magnon frequency band) is impossible.
