| 摘 要： | 用直径为0.24mm的不锈钢金属丝细丝网格制作细丝网格教学道具,给出了具体制作方法。利用当前先进的微钻技术在0.2mm厚的薄铜片上精确加工出直径为0.1、0.2、0.3和0.5mm的四个小孔制作出低通滤波器,比较了不同大小孔径小孔的低通滤波效果。利用大头针的针尖制作出高通滤波器,并购买狭缝滤波器,从而将阿贝-波特实验成功再现。

| Abstract: | The filament gridding teaching aid is made from metal filament gridding with stainless steel filament of a diameter of 0. 24mm, and the detailed making process is presented. Using current ad- vanced tiny drill technology, the low- pass filter is made by drilling 4 tiny holes of diameters of 0.1mm, 0. 2mm,0.3mm and 0. 5mm respectively,on a piece of thin copper flake with thickness of 0. 2mm,and the filtering effects of tiny holes of different diameters are compared. The high pass filter is made of the needlepoint of pin, and the slot filters are bought,and then the Abbe-Porter experiment is success- fully reconstructed. |
