中文摘要 |
以理想溶液為模型對溶質結晶過程的熱力學問題進行了深入的討論,指出溶質結晶平衡包含著穩定平衡和非穩定平衡;溶質結晶時,體系首先要翻越一非穩定平衡的能峰,然後進入一穩定平衡的能谷;當溶液被稀釋時,能峰變高,能谷變淺;當溶液被稀釋至一定程度時,能峰和能谷合二而一。 |
英文摘要 |
Thermodynamic problem for solute crystallizing are discussed thoroughly by introducing a model of ideal solution, it is pointed out that the equilibrium for solute crystallizing contains stable and unstable equilibrium; during the process of solute crystallizing, the system must cross a peak of an energy of the unstable equilibrium at first, then get into an energy valley of the stable equilibrium; when the solution is diluted, the peak of the energy gets tall, and the energy valley gets shallow; when the solution is diluted to a certain extent, the peak of an energy and the energy valley combine into one. |
