摘要：

New models of Mercury's internal structure are calculated for different amounts of sulfur in the core. The density of an FeS core differs by only about 0.5% from the mean density of Mercury. A determination of Mercury's moment of inertia will effectively discriminate among the models and place relatively tight constraints on the radius and sulfur content of the core despite relatively large uncertainties in the density and temperature of the silicate mantle.
