| 摘要: |
| 假定重夸克碎裂函数β-分布的动力学参数味修正与重夸克质量效应等价,结合碎裂函数的峰值随重夸克质量的增大而向大z方向偏移的实验数据,计算出重夸克t、b的质量,理论计算结果与实验数据符合较好. |

| Abstract: |
| The flavor dynamic parameter modification of heavy quarks'fragmentation function(β-distribution function) has been assumed to be equal to its mass effect. The experimental dato show that the peak of fragmentation function shifts to ligger z value with the mass of quark.The mass of heavy quarks t and b have been calculated according to the two facts mentioned above.The calculation result was in good accordance with the experimental data. |
| Key words: heavy quark mass of quarks fragmentation function flavor dynamic parameter |
