报道了甲烷磺酸、硫酸、硝酸、高氯酸和三氟甲磺酸在无水DMSO中的稀溶液的电导测量结果，测量温度为25℃。根据Fuoss-Hsia电导方程对结果进行了分析。缔合常数按上述顺序递减，实际上，高氯酸和三氟甲基磺酸在DMSO稀溶液中可视为完全解离。文中还报道了二甲基亚砜中λ∞(H+)的可靠取值。
Conductance measurements of 25°C are reported for dilute solutions of methanesulphonic, sulphuric, nitric, perchloric and trifluoromethanesulphonic acids in anhydrous DMSO. The results are analysed in terms of the Fuoss—Hsia conductance equation. The association constants decrease in the above order, indeed perchloric and trifluoromethanesulphonic acids can be treated as completely dissociated in dilute solution in DMSO. A reliable value for λ∞(H+) in DMSO is also reported.
