【摘要】 本文论证了几种可行的方案，设计了一个小型的一维超微进给工作台，并介绍了我校研制的ＣＱＲ－Ⅲ型超薄切片机的工作原理，设计要点和使用情况，该机可切厚度为５－１５ｎｍ的电镜样品，其允许的厚度误差仅为±５ｎｍ。更多还原

【Abstract】 Abstract The possible schemes are demonstrated in the paper,A small ultramicro-feed holder are designed.The principle and characteristic of CQR-Ⅲ Ultramicrotome aredescribed,which in developed by Shanghai University of Science and Technology.The elec-tron microscope specimens and sections can be made by CQR-Ⅲ.The thickness of sectionsis 5-150nm,while its error of thickness is about ±5nm.更多还原
