这里介绍一种很简便的小巧算尺的制作方法。如图,就是按原来大小摄制下来的笔者自制的小算尺的照片。显然这可以说是一种最小、最轻、造价最便益的小算尺。可以夹在小日记本里随身携带,以便于在现场、在工地、在试验室里、在会议桌上随时使用。中专、大专学生更可以通过自制算尺,进一步了解算尺的构 Here is a very simple method of making small scales. As shown in the picture, the author made a small picture of the scale made by the original size. Obviously, this can be said to be the smallest, lightest and most cost-effective small scale. It can be carried around in a small diary so that it can be used on site, on the job site, in the lab, at the conference table. Secondary school and college students can further understand the structure of the rule by using self-control rules.
