| Abstract: | In this paper the results of thermoluminecence (TL) study on Bo County meteorite are reported. Temperature gradient in the meteorite, produced by heating during its atmospheric passage, is 34.2°C/mm in head, 24.8°C/mm in side. The temperature profiles of the meteorite is closed to the Barwell meteorite, and more reasonably consistent with the steady-state solution to the heat conductivity equation in a case of the ablation rate of 0.10 cm/sec. According to the TLcurve of the meteorite the parameter Ln (LT/HT) is 1.30. So the meteorite belong to type A. |
