在使用透射式电镜观察样品的过程中,不仅要观察样品的形貌,有时也要在荧光屏上粗略地测定组织的基本结构尺寸。因此在电镜荧光屏上加注标尺,对研究人员来说是很方便的。目前所应用的荧光屏大多不加际尺,仅有少数进口的小荧光屏带标尺。为此,本文介绍一种在小荧光屏上加注标尺的简单方法。更换小荧光屏荧光屏经过长期使用,会导致不可恢复的光输出下降,也可能因强烈的电子束集中照射而被“灼伤”,这两种情况都需要更换新的荧光屏。加注标尺的工作可以在此时进行。将旧荧光屏的荧光粉刮下,把基板用丙酮或其它有机溶剂清洗干净,采用自然沉降法制取一块新荧光屏。制备模板 In the observation of a sample using transmission electron microscopy, not only the morphology of the sample but also the rough structure of the tissue should be roughly measured on a fluorescent screen. Therefore, filling the electron microscope screen scale, the researchers is very convenient. At present, most of the screen is not added with a ruler, only a small number of imports of small fluorescent screen with ruler. For this reason, this article presents a simple way of filling a scale on a small fluorescent screen. Replacing Small Fluorescent Screens Long-term use of fluorescent screens can result in diminished unrecoverable light output or “burns” due to intensive electron beam irradiation, both of which require the replacement of a new fluorescent screen. The filling of the ruler can be done at this time. Scratch the old fluorescent screen phosphor, the substrate with acetone or other organic solvents to clean, using natural sedimentation method to create a new screen. Prepare the template
