论文摘要
当将少量的溶质添加到混合物中时，我们对水样的最大密度（TMD）温度的变化进行了建模。该溶剂被建模为两个长度尺度电位，已知会表现出类似水的特征异常，而溶质被选为与溶剂具有吸引人的相互作用，该溶剂从小到大的有吸引力的潜力调节。我们表明，如果溶质对溶剂表现出很高的吸引力，则它作为结构制造商的表现，而TMD随着溶质的添加而增加，而如果溶质与溶剂显示出低吸引力，则TMD会降低，溶质的溶质表现为结构断裂器。
We modeled the change in the temperature of maximum density (TMD) of a water-like solvent when small amounts of solute are added to the mixture. The solvent is modeled as a two length scales potential, which is known to exhibit water-like characteristic anomalies, while the solute is chosen to have an attractive interaction with the solvent which is tuned from small to large attractive potential. We show that if the solute exhibits high attraction with the solvent it behaves as a structure maker and the TMD increases with the addition of solute, while if the solute shows a low attraction with the solvent the TMD decreases, with the solute behaving as a structure breaker.
