随着国防工业、电子、电气工业及新技术的飞跃发展,对铜及其合金质量,特别是对其中气体杂质含量的要求也越来越高,铜中氧含量直接影响产品的导电、机械、焊接性能及使用寿命,尤其是在超真空技术方面,严格要求较低的氧含量,因此如何快速、准确测定铜中氧含量已成为当今气体分析工作者的一项重要的研究课题。 With the rapid development of national defense industry, electronics industry, electric industry and new technology, the requirements on the quality of copper and its alloys, especially the content of gas impurities therein are also increasing. The content of oxygen in copper directly affects the conductivity, mechanical, Welding performance and service life, especially in the ultra-vacuum technology requires a relatively low oxygen content, so how to quickly and accurately determine the oxygen content of copper has become an important research topic of today’s gas analysis workers.
