中文摘要：

将广义力对系统做功引起的能量（不含冷能）的相对变化аEs／Es与广义坐标的相对变化аy／y之比定义为微观Gruneisen系数γs，导出了计算Gruneisen系数统计平均值的微分方程．由该方程计算了人们熟悉的热力学系统的Gruneisen系数，结果与其他方法得到的结论完全一致．

英文摘要：

The ratio of the change of energy （barfing cold energy） from the work of generalized force done to the system and the variation of generalized coordinate of system is defined as the microcosmic Gruneisen coefficient. The differential equation for calculating statistical average value of this coefficient is obtained. The result is in agreement with other methods.
