Following Randall and Failey some assumptions about the activity coefficients of the ions of o-nitrobenzoic acid in salt solutions were made and thereby it was possible to calculate the activity coefficients of its undissociated molecules in these solutions .

关于邻硝基苯甲酸根离子在这些盐溶液中的平均活度系数，作者仿照前人作某些假设，从而计算出该酸的 未 离解分子在盐溶液中的活度系数fu。

In addition there are some rather stable AlF_3 in the undissociated AlF_6 ~ ( 3 - ) complex ions andAI_2F_7 ~ - ions are also formed due to the interactions among various species .

此外在 未 分解的AIF6~（3-）离子中存在比较稳定的AlF3由于质点间的交互作用还形成Al2F 7~-离子。

Lactic acid and acetic acid showed an inhibitory effect toward bacillus subtilis if the undissociated form was more than 0.683 % and 0.256 % respectively .

当乳酸和醋酸 其 未 解离 部分 的 浓度分别大于0.683%和 0.256%时对枯草芽胞杆菌有抑菌作用；

Water species adsorb On the surface mainly in the form of undissociated molecules .

水汽主要以 不 分解的分子 态形式吸附在表面。
