在同学们初学使用显微镜、使用技术尚未熟练时,一不小心就会将标本片上的盖玻片打破,尤其在揩擦盖玻片时,更容易打破。这样,盖玻片的损耗量很大,的确是值得注意的一个问题。应当想办法来克服这个巨大的损耗,因此作者在去年试将照相软底片,来代替盖玻片,现在将试验的结果写在下面,以供参考。将照相底片放在5%稀硝酸溶液中浸24小时,这时底片上的胶已经溶化,用手拿上去有滑腻感觉,把这种底片放在清水中,用软布(纱布)轻轻揩擦,就能很容易的将底片上已经溶化的胶擦去,用水冲洗净后,在光亮处见其完全透明,是表示胶已
Students are beginning to use the microscope, the use of technology is not yet skilled, the accidental will cover the glass slides on the specimen to break, especially when rubbing coverslip, easier to break. In this way, a large loss of cover glass is indeed a problem worth noting. We should find a way to overcome this huge loss, so the author tried photographic film last year to replace the cover glass, the results of the trial are now written below, for reference. The photographic film on a 5% dilute nitric acid solution immersed in 24 hours, then the film on the gel has been melted, hand up with a creamy feeling, the film on the water, soft cloth (gauze) gently 揩Rub, it will be very easy to rub the negatives already melted on the film, washed with water after the net, in the light to see it completely transparent, is that glue has
