本文用非弹性X射线散射研究了硫在液-液λ跃迁中的高频声动力学。这些高频数据与低频文献数据的组合表明，液体硫在高温聚合物溶液相中形成橡胶的某些特征。特别是，聚合物链之间的缠结耦合在该液相的动力学中起着相关的作用。
The high-frequency acoustic dynamics of sulfur across the liquid-liquid, lambda transition has been studied using inelastic x-ray scattering. The combination of these high-frequency data with lower frequency, literature data indicates that liquid sulfur develops, in the high-temperature, polymeric solution phase, some characteristic features of a rubber. In particular, entanglement coupling among polymeric chains plays a relevant role in the dynamics of this liquid phase.
