为液体金属的密度测量的膨胀计方法被改进与简单操作给高测量精确性。液体锡的密度被测量,结果与在文学的价值一致。液体 Snwas 的融化的点密度测量了是 6.966 X 10 ~ 3 Kg 中心点 m~(-3) 和为液体 Sn 的密度(p) 的温度(T) 依赖能好由多项式方程 p (T) 描述了 =7.406 - 9.94 X10~(-4)T + 2.12 X 10 ~(-7)T~2。
The dilatometer method for density measurement of liquid metals was improved to give a high measurement accuracy with simple operation. The density of liquid tin was measured and the results are in agreement with values in literature. The melting point density of liquid Sn was measured to be 6.966×10^3 Kg·m^-3 and the temperature (T) dependence of the density (p) for liquid Sn can be well described by a polynomial equation p(T)=7.406 - 9.94 × 10^-4T + 2.12 × 106-7T2.
