| 摘 要： | 讨论了高能部分子穿过夸克胶子等离子体时热胶子的细致平衡效应，在热介质中，受激的热胶子发射降低部分子的能量，而热吸收增加部分子的能量，其净贡献导致部分子能量损失的减少。部分子能量损失的相对减少对中等能量的喷注是重要的，而对非常高能量的喷注可以忽略不计。修正后的能量损失对能量的依赖性将影响中等户t强子谱压低的形状。

| Abstract: | The detailed balance effect of the thermal gluon for an energetic parton propagating inside a quark-gluon plasma is discussed. In the thermal medium, the stimulated thermal gluon emission reduces while absorption increases the parton's energy. The net contribution result in a reduction of the parton energy loss. The relative reduction of the parton energy loss is found to be important for intermediate energies and can be neglected for very high energies. The modified energy dependence of the energy loss will affect the shape of suppression of moderately high pT hadrons spectrum. |
