| 摘 要： | 提出新的碰撞模型，通过模拟几种只含两种质量粒子的一维链的能量传递，研究质量分布对热导的影响．得出的T-N图显示质量比在1到3之间时，链上的温度分布存在部分梯度，当质量比大于3时．链上粒子的温度分布不存在梯度，整体处于单一温度值T附近，而且平均温度仅与链上粒子的质量分布有关．

| Abstract: | A new collision model was put forward, the influence of mass distribution on the heat conduction was studied through simulating the energy, transportation in some one-dimensional chains which only have two different masses. The calculated T - N profiles show that it has gradient characteristic in the temperature distribution when the mass ratio is between 1 and 3. However, for larger mass ratio, the gradient in several chains no longer exist, and the whole chain is near a stable average temperature. Moreover, it is found that the average temperature is only relative to mass distribution. |
