1 前言 目前光学显微镜和扫描电镜大多数照像系统都配制135或120相机,故冲洗胶卷对金相分析工作者来说是一项经常性的工作。冲洗胶卷质量的好坏直接影响分析结果,除胶卷质量和拍照过程中参数控制外,金相暗室中的操作方法是至关重要的。在实际工作中,我们发现有时冲洗的胶卷不是显影不均就是胶卷划痕太多,导致底片不能用,而不得不重拍,浪费了太多时间,针对这种情况,经多次实践,证明用下述方法冲洗可获得较高质量的底片,而无一发生上述现象。
1 Introduction Optical microscopes and scanning electron microscopes are currently equipped with 135 or 120 cameras for most photographic systems. Flushing film is a recurring task for metallurgical analysts. Rinse film quality directly affects the quality of the results, in addition to the film quality and control parameters in the process of taking pictures, darkroom operation method is crucial. In practice, we found that sometimes the processing of film is not uneven development is too much film scratches, resulting in the film can not be used, and had to remake, wasting too much time, in view of this situation, after repeated practice, that Flushing using the method described below resulted in a higher quality film, none of which occurred.
