自从Kruyt和Bungenberg de Jong的论文发表以来，人们通常认为溶剂化或水化作用是胶体体系的第二稳定性因素。然而，到目前为止，应用于胶体稳定性的溶剂化概念仅仅是定性的，这反映了不同作者赋予它的不够精确和经常相互矛盾的含义。因此，通常没有明确区分溶剂化层的机械性质的变化和导致粒子接近时的相互作用力的热力学性质的变化。因此，我们将避免使用溶剂化这一术语，而用第二类力来代替第二类力，后者与第二热力学有关。
Since the appearance of the papers by Kruyt and Bungenberg de Jong, a it is customary to consider solvation or hydration as the second stability factor of colloidal systems. However, up to the present the concept of solvation, applied to the stability of colloids, was qualitative in character only, which reflected the insufficiently precise and often contradictory meaning assigned to it by different authors. Thus, usually no clear distinction was made between the changes in the mechanical properties of solvated layers, and the changes in the thermodynamical properties which lead to the forces of interaction when particles approach. Hence, we shall avoid the use of the term solvation and speak instead of forces of the second kind, which are connected with the second thermodynamical
