More precise and comprehensive analytical results for lunar material in Sinus Medii have been derived from the alpha-scattering experiment on Surveyor VI. The amounts of the principal constituents at this mare are approximately the same as those of constituents at Mare Tranquillitatis. The sodium contents of both maria are lower than those of terrestrial basalts. The titanium content at Sinus Medii is lower than that at Mare Tranquillitatis; this suggests important differences in detailed chemical composition at different mare areas on the moon.
从“勘测者 6 号”阿尔法散射实验中得出了对“月海”（Sinus Medii）月球物质更精确和全面的分析结果。该月海的主要成分含量与“月海静海”（Mare Tranquillitatis）的大致相同。两个月海的钠含量都低于地球玄武岩。“月海”（Sinus Medii）的钛含量低于“月海静海”（Mare Tranquillitatis）；这表明月球上不同月海区的详细化学成分存在重要差异。
