一般说来,感光测定就是利用感光材料光线强弱而相应变化的关系,通过数据表达其照相性能的一种手段。感光测定所提供的数据准确与否,不仅关系到感光材料的研究、制造和使用的监测控制,而且直接影响这方面的技术交流和质量评介。笔者认为,造成感光测定各异的原因是多方面的,也是十分复杂的。在我国的现有条件下,它不单是仪器设备、测试方法问题,而且还涉及操作技术、药液质量和管理控制等问题。因此,在技术管理方面,除实现全
In general, photometry is the use of light-sensitive materials, the corresponding changes in the relationship between the intensity of light through the data to express their photographic performance as a means. Sensitivity of the data provided by the accuracy or not, not only relates to the photosensitive material research, manufacture and use of monitoring and control, but also directly affect the technical exchange and quality evaluation in this area. The author believes that the causes of different sensitometric determination are many, but also very complicated. Under the existing conditions in our country, it is not only a problem of instruments and equipment and testing methods, but also involves such issues as operation technology, liquid chemical quality and management control. Therefore, in terms of technical management, in addition to achieving full
