Abstract：
The D _B-D ₁relations are presented in this paper by measuring background darkness of the X-ray films in No.K0—K7 chambers,in addition,different distributions of the background darkness of X-ray films are measured.They may be taken as somemuseful parameters in energy calibration and other respects for future EC experiments.
