中国机械工程学会各级学术组织和地方学会,在开展各种为经济建设服务的活动中取得了许多成效。为配合今年6月中国机械工程学会55周年年会的召开,从这一期始,陆续择其中的若干项予以刊出,以交流这些工作成果。 氮基气氛技术委员会的活动推动了我国氮基气氛热处理的发展 我国液化石油气供应、储藏等问题长期未能解决,严重阻碍了以液化石油气为原料气的控制气氛热处理炉的发展。为此,1981年5月中国机械工程
The Chinese Academy of Mechanical Engineering at all levels of academic organizations and local societies has achieved many results in carrying out various activities for economic construction. To cope with the holding of the annual meeting of the 55th Anniversary of China Mechanical Engineering Society in June this year, from this period onwards, a number of items were selected for publication in order to exchange the results of these works. The activities of the nitrogen-based atmosphere technical committee promoted the development of nitrogen-based atmosphere heat treatment in China. The supply and storage of liquefied petroleum gas in China have not been solved for a long time, which has seriously hindered the development of control atmosphere heat treatment furnaces using liquefied petroleum gas as raw material gas. For this reason, May 1981 China Mechanical Engineering
