一百多年以来,普通生物制片技术一直是组织学工作者进行教学和科学研究的重要手段,而旋转式切片机乃是普通制片技术常备的重要工具之一。但是,在制片的过程中,经常遇到的一个棘手问题就是磨刀,特别是手工磨刀,既费时间,初学者也不易熟练掌握,而磨一次刀,只能使用几次,一旦出现刀口就很难磨平。虽然自动磨刀机的发明和使用,能够代替手工磨刀,但是,自动磨刀机的价值较贵,并且磨刀也颇需时间。此外,一般切片刀只能切到6微米厚,再切簿就比较困难了。能否克服上述普通切片刀的这些缺点呢?近几年来,国
For more than one hundred years, ordinary bioproduction technology has always been an important tool for teaching and scientific research by histologists. Rotary microtome is one of the most important tools in the field of common production technology. However, in the production process, one of the most troublesome problems often encountered is sharpening, especially manual sharpening, which takes time and is not easy for beginners to master. However, when sharpening a knife, it can only be used several times. Once it appears Knife is hard to level. Although the automatic knife sharpener invention and use, can replace manual sharpening, but the automatic sharpener is more expensive, and sharpening also takes time. In addition, the general slicing knife can only be cut to 6 microns thick, and then cut the book more difficult. Can overcome these shortcomings of the above ordinary slicing knife? In recent years, the country
