过去由电镜底片制作成幻灯片要经过:先把电镜底片放大成照片,把照片翻拍成负片、对负片拷贝而成幻灯片。这方法步骤复杂,难免造成一些微细结构的丢失。最近,我们对操作的方法进行了改进,采用直接翻拍成底片一步制作成幻灯片的方法。所得的结果与通常使用的方法比较,质量显著提高,较好地保存了底片原有的微细结构图象。而且,操作简便,提高了工作效率,节省了原材料。现将方法介绍如下: In the past produced by the film made of electronic slides to go through: first electron microscope film zoom into photos, the photo into a negative film, a negative copy of the slide. The method steps are complicated and inevitably result in the loss of some fine structures. Recently, we have improved the method of operation by using a method of making a slideshow directly from one film to another. The results obtained were significantly improved compared with the commonly used methods, and the original fine structure image of the film was well preserved. Moreover, easy to operate, improve work efficiency, save raw materials. The method is introduced as follows:
