| 摘 要： | 从价夸克和海的相互作用导致小x区域价夸克极化程度软化的模型出发,具体考虑韧致幅射作为价夸克和海相互作用的机制,使小x区域的不对称度压低,所得结果与EMC数据符合很好.

| Abstract: | From the model that interaction between the valence quarks and the sea results in the valence quarks spin-delution in the small-x region,the bremsstrahlung has been considered as a mechanism of interaction between the valence quarks and the sea, which reduce the spin asymmetry in the small-x region. The theoretical predictions are in agreement with the EMC data. |
