This work presents a study of the reciprocal dispersive power, also known as constringence or Abbe number of an aqueous solution of NaCl in a wide range of concentrations. The constringence exhibited a distinct behavior in the region close to the phase transition between a phase containing exclusively brine and a phase containing brine+halite. Molecular dynamics simulations of this system indicated the existence of halite formation below the known saturation curve, which agreed with the experimental measurements, indicating a crystal growth in the unsaturated region.

通过光学收敛和分子动力学研究盐水-岩盐相分离

这项工作介绍了对各种浓度的 NaCl 水溶液的相互色散能力(也称为收敛性或阿贝数)的研究。在接近仅含有盐水的相和含有盐水+岩盐的相之间的相变的区域中,收缩表现出明显的行为。该系统的分子动力学模拟表明在已知饱和曲线以下存在岩盐形成,这与实验测量结果一致,表明晶体在不饱和区域生长。
