前言在这里叙述的金属波纹管直径为几毫米到几百毫米左右。主要用在测量仪器上作为敏感元件。通常采用的材料有磷青铜、铍青铜、奥斯体不锈钢等等。本文记述的内容,只限使用者对波纹管制造厂的要求,是一篇简单的参考性介绍。所介绍的内容与一般学术研究报告不同,这是这篇文章的特点。第二次世界大战后为了各种不同的使用目的迅速地采用了波纹管,尤其在自动装置方面得到了大量的应用。其结果使工厂只忙于制造而根本没有功夫进行研究。制造厂只努力于生 Preface The metal bellows described here have diameters of a few millimeters to a few hundred millimeters. Mainly used in measuring instruments as a sensitive element. Commonly used materials are phosphor bronze, beryllium bronze, Austenitic stainless steel and more. This article describes the content, only the user of the bellows factory requirements, is a simple reference introduction. The content is different from the general academic research report, which is the characteristic of this article. After World War II, bellows were rapidly adopted for a variety of different purposes, especially in the field of automatic devices. As a result, the factory was busy with manufacturing and did not study hard at all. The factory only works hard
