摘　　要：本文以化工部第一胶片厂生产的乐凯5141型黑白电影正片为对象,对镍物理显影二级放大进行了研究,内容包括对感光材料感光性能影响,影像区无电镀镍,配制稳定、高效的镍物理显影液。研究表明,镍物显二级放大可以大幅度提高感光材料的光密度和反差系数,使用自行研制的镍物显液,可以省略活化步骤,提高二级放大后影像清晰度。This paper reports a study on the second-level amplification of nickel phsical development using 'Lucky'black-and-white positive cine-film type 5141 made by No.1 Film Factory of Ministry of Chemical Industry, The report includes the effect on photographic properties of photographic materials, the non-electric nickel plating of image area and the preparation of stable and hi-efficiency nickel physical developer. Results showed that the second-level amplification of nickel physical development may increase significantly the optical density and contrast of photogrphic materials. Using solution prepared by ourselves tor nickel physical development, the activation step may be omitted and the sharpness of image obtained by second-level amplification may be improved.
