南丹铁陨石物态方程用于地核的研究
APPLICATION OF EQUATION OF STATE OF NANDAN IRON METEORITE TO EARTH’S CORE
【摘要】 从南丹铁陨石的物态方程和地球的PREM模型出发,求得内外地核交界面处的物质密度为12.83—13.419/cm~3,温度为5440—5680K;地心处物质密度为13.12—13.73g/cm~3,温度为5660—5990K,推估内地核可能由铁镍合金组成.
【Abstract】 Based on the equation of state of Nandan iron meteorite and the PREM model of the eaath, it is calculated that the material density at the boundary between inner core and outer core of the earth is 12.83-13.41 g/cm3 and the temperature is 5440-5680 K; the material density at the center of the earth is 13.12-13.73 g/cm3 and the temperature is 5660-5990 K, respectively. !t is estimated that the inner core of the earth may be consisted of Fe-Ni alloys.
