【Abstract】 The relation between Debye temperature （?） and other physical quantities is shown as: Ⅰ_T/Ⅰ=e^-2M （1）Where Ⅰ is the intensity of X-Ray diffracfionat o°K Ⅰ_T is the intensity of X-Ray Diffraction at T°K 2M=-（12h²/m_ak（?））{(φ（X）/X+1/4}（Sin²θ）/λ² （2）In this paper the. Debye temperature of FeB has been measured, using the instrument of X-Ray diffraction at high temperature. Based on （1） and （2） formulas, the results are as follows:The average Debye temperature is 24000°K between the temperature 900-1100 k.更多还原
