| 摘 要： | 提出了微扰ＱＣＤ的高级修正Ｋ因子的经验公式，与有关实验符合得相当好。Ｋ因子随ｍ的增大而缓慢减小这一事实支持了ＱＣＤ渐进自由性质的一贯要求和以往关于Ｋ因子的直接实验结果。指出各种Ｄ－Ｙ过程的动力学实质相同，Ｋ因子经验公式的动力学实质有待进一步研究。

| Abstract: | The experience formula of K factor in perturbative QCD is produced and in good agreement with related experimental data.The fact that K factor decreases slowly as m increases have supported the consistent requirement of approaching freedom in QCD and the direct experimental result of K factor.We also point out that the substance of each D-Y process is same and the dynamics substance of the experience formula about K factor remain to be further researched. |
