磁悬浮书写工具是一种可多次重复使用的无尘书写工具,七十年代首先在日本、美国成熟起来,并相继在日、美等十几个国家取得专利。自一九八二年以来我们就其原理和主要工艺问题做了探讨和实验,其主要方面已见端倪,这就是本文所要阐述的。 Magnetic levitation writing instrument is a kind of dust-free writing instrument that can be reused many times. In the seventies, it first matured in Japan and the United States, and was successively patented in over a dozen countries such as Japan and the United States. Since 1982, we have discussed and experimented on its principles and major technological issues. The main aspects of this issue have already begun to emerge. This is what we are going to elaborate in this article.
