随着我国四个现代化步伐的迅速迈进,随着我国人民的物质生活与精神生活水平的不断提高,对摄影技术的需求也愈加迫切,而摄影技术中一个很重要的问题,是对摄影所用感光材料的照相性能的了解,它不仅影响着拍摄条件的选取,而且在冲洗过程中也占有相当重要的地位。但目前这方面的知识很不普及,不仅表现在广大群众中,甚至在高等院校的不少物理专业的师生中也表现突出,因此有必要在这方面做工作。卤化银感光乳剂是目前应用最广泛,较成熟的永久性记录材料。它的照相性能的参数
With the rapid progress of our four modernizations, with the continuous improvement of the material and spiritual life of our people, the demand for photographic technology is becoming more pressing. One of the most important issues in photographic technology is the photographic sensitivity Material understanding of the photographic performance, it not only affects the selection of shooting conditions, but also in the process of flushing also occupy a very important position. However, at present, the knowledge in this area is not widely used. It is not only manifested in the general public but also among many physical majors in institutions of higher learning. Therefore, it is necessary to do work in this respect. Silver halide emulsion is the most widely used, more mature permanent recording material. Its photographic performance parameters
