摘要
采用分子动力学(MD)模拟的方法对超临界条件下水的结构及扩散性质进行了研究.模拟结果表明超临界条件下水分子之间的氢键作用明显减弱,分子极性大大降低.扩散性质与常温下相比,其大小约上升了两个数量级.
The hydrogen bond structure and diffusion behavior of water at supercritical states were investigated by MD simulation.A great number of new simulation data of radial distribution functions,hydrogen bond structures and diffusion properties of supercritical water were obtained.The hydrogen bond interaction between supercritical water molecules decreases dramatically whereas the diffusion properties of supercritical water increase by two orders of magnitude.
