Densities of glycylglycine in sucrose-water mixed solvent have been measured at 288.15, 298.15 and 308.15 K by Anton Paar DMA55 vibrating-tube digital densimeter. The apparent molar volume VΦ, limiting partial molar volume , partial molar volumes of transfer Δtrs from water to sucrose-water mixed solvent and the hydration numbers Nh for glycylglycine have been calculated.

利用Anton Paar DMA55精密数字密度计测定了288.15， 298.15和308.15 K甘氨酰甘氨酸在蔗糖-水混合溶剂中的密度，计算了甘氨酰甘氨酸的表观摩尔体积VΦ和极限偏摩尔体积，得到了其由纯水溶剂转移至混合溶剂中的迁移偏摩尔体积Δtrs 和理论水化数Nh。
