| Abstract: | The paper presents how to learn how much information X - ray negative film carries by usingthe method of entropy in optical information theory , under the fixed condition, through the quantitivecalculation of the same shot subject and under the condition of different random rays, so that the effect ofrandom ray on negative image quantity can be assessed effectively. |
