摘要翻译：
我们用NVE分子动力学模拟了过冷玻璃形成液中的结构弛豫。总动能涨落的时间关联被用来作为系统接近遍历平衡的综合度量。我们发现，在冷却条件下，总的结构弛豫比对应于结构因子主峰的中间散射函数分量的衰减延迟。这一观察可以用在紧凑的三维协同重排区域内保持多体结构关联的粒子集体运动来解释。

英文摘要：
  We examine structural relaxation in a supercooled glass-forming liquid simulated by NVE molecular dynamics. Time correlations of the total kinetic energy fluctuations are used as a comprehensive measure of the system's approach to the ergodic equilibrium. We find that, under cooling, the total structural relaxation becomes delayed as compared with the decay of the component of the intermediate scattering function corresponding to the main peak of the structure factor. This observation can be explained by collective movements of particles preserving many-body structural correlations within compact 3D cooperatively rearranging regions.
