俄罗斯斯阔琴斯基矿业研究院卡尔波夫等人发表文章介绍了前苏联和俄罗斯发展热催化瓦斯测量元件的三个阶段。文章指出，瓦斯测量元件的制作工艺可分为三个发展阶段或三代。第一代工艺基于使用标准的γ－Ａｌ２Ｏ３，它是由生产这类产品的工厂以微粒或凝胶状半成品的形式提供的? Karpov and others from Slukkonsky Mining Research Institute of Russia published an article introducing the three stages of the development of thermal catalytic gas measuring elements in the former Soviet Union and Russia. The article points out that the gas measuring element manufacturing process can be divided into three stages of development or three generations. The first-generation process was based on the use of standard γ-Al2O3, which was supplied as a particle or gel-like semi-finished product from the factory where the product was made.
