Abstract：
By measuring the background darkness D _Bof each yeai's (K0-K7) X-ray films, this paper presents the correlations between D _Band energy calibration value D ₁. Several distributions of X-ray film's D _Bare measured. The measured results can be used as the useful parameters for energy calibration and emulsion chamber experiments.
