对晶格自旋相互作用的交换积分进行了晶格振动的修正，依此修正，导出了振动对磁记录膜矫顽力的影响关系；分析了磁晶量子尺度效应对磁记录膜矫顽力的影响机制；讨论了振动效应和量子尺度效应相互影响，共同竞争的物理内涵。结果显示：①振动的存在将减小薄膜的矫顽力；②磁晶微粒的量子尺度效应将使薄膜的矫顽力增加；③振动效应和量子尺度效应相互影响，共同竞争，为薄膜提供矫顽力；④要提高薄膜完备系的矫顽力，可将磁记录膜制成纳米级薄膜。

The exchange integral for crystal spin interaction has carried out the correction of crystal lattice vibration, according to this correction, have gotten Influence relation of vibrates to coercive of magnetic record film; Have analysis the influence mechanism of magnetic crystal quantum scale effect to coercive force of magnetic reoord film; Have discussed the physical intension of vibration effect and the quantum scale effect it's mutual influence of and common competitive. Show as a result: 1 Vibration existence will reduce the coercive force of the film; 2 Magnetism the quantum scale effect of crystal particle will make the coercive force of film increase; 3 Vibration effect and the quantum scale effect mutual influence and common competition offer coercive force for film; 4 Will raise the coercive force of film complete department, Can make magnetic record film to make nanometre level film.
