A hydration number of 20 has been measured for aqueous CH4 in the temperature range 273-298 K on the basis of the simultaneous observation of the 13C isotropic resonance lines of CH4 in both aqueous solution and the dodecahedral cage of CH4 structure I hydrate. Additional experimental evidence and analysis reported in this paper suggest that the dominant aqueous hydration number of methane is 20.
基于对甲烷在水溶液和甲烷结构I水合物十二面体笼中的13C各向同性共振线的同时观测，在273 - 298 K温度范围内测得甲烷水合物的水合数为20。本文报道的其他实验证据和分析表明，甲烷主要的水合数为20。
