  "abstract": "During the ascending and descending phases of some black hole X-ray binaries(BH XRBs), it was found that the X-ray Eddington ratio ($ L_{X-ray(3-25keV)}/L_{Edd} $) and the photon spectral index $Γ$ had an anticorrelation when the X-ray Eddington ratio was less than a specific value, and a positive correlation when it was greater than that value. Moreover, the cross points of the anticorrelation and positive correlation are different for different BH XRBs ($ L_{X-ray(3-25keV)}/L_{Edd} $ of cross point is between $ 0.1 \\% $ and $ 10\\% $). The reason why the cross points are different for different BH XRBs were still uncertain. So we processed the light curve and energy spectrum of 15 outbursts of eight BH XRBs during their descending phases. We found that for the same BH XRB, the values of the X-ray Eddington ratio at the cross point are basically consistent for different outburst times. However, for different BH XRBs, there is a positive linear correlation between the X-ray Eddington ratio at the cross point and the cosine of the accretion disk inclination. Therefore, We think that the geometric effect of the inclination has a significant impact on the evolution of the energy spectrum of the BH XRBs.",
