通过引进新的照相技术，实现了核乳剂胶片的工业化批量生产。此外，通过控制凝胶的褪色特性，实现了乳液的刷新能力（在使用前擦除不需要的轨迹）。为了满足这一要求，对凝胶性能进行了优化;在实验运行过程中，在擦除条件下快速擦除轨迹，使衰落最小。具有这种能力的乳剂薄膜对于大规模应用至关重要，如长基线中微子实验OPERA，该实验旨在探测距离光束源732公里处的Tau中微子的外观。(c) 2005年Elsevier B.V.出版
Industrial mass production of nuclear emulsion film has been realized by the introduction of new photographic technologies.In addition, emulsion-refreshing capability (erasing unwanted tracks before its use) was implemented by controlling the fading characteristics of the gel. The gel properties were optimized in order to satisfy this requirement; rapid track erasing at the erasing condition and minimum fading during the running of experiments.Emulsion films with this capability are crucial for large-scale applications like the long base-line neutrino experiment, OPERA, which intend to detect Tau neutrino appearance at 732 km from the beam source.
