电子技术中所用的钨、钼等细金属絲必须具有严格恒定的直径。某些检查细金属丝直径的仪器,如英国国家物理研究所(NPL)制造的都是专门供试验室使用的。这类仪器既复杂又昂贵,而且不能进行连续测量。以本文作者改进的机械—电动式测微仪(mechanotron micrometer)为基础,制成了一种比较简单的仪器,可用来连续检查细金属丝。这种装置既适用于试验室也适用于生产车间。——编者
Electronic technology used in tungsten, molybdenum and other fine metal wire must have a strict and constant diameter. Some instruments that inspect fine wire diameters, such as those produced by the National Institute of Physics (NPL), are designed for laboratory use. Such instruments are both complicated and expensive, and can not be measured continuously. Based on the mechanotron micrometer improved by the author of this article, a relatively simple instrument is made that can be used to continuously inspect thin metal wires. This device is suitable for both laboratory and production workshop. --editor
