由国家科委领导和组织的常用材料大型环境试验在经过多年筹备后,已于今年9月分别在兵器部五四所中心站、海南站,以及广州、青岛、北京、武汉等地8个试验站投试.样品均系我国在国民经济发展中用量既大而广的常用材料,其中包括黑色金属、有色金属、涂层、镀层、工程塑料等四万余件试样.试验为期十六年.通过试验对各种材料积累在不同环境条件下,可靠的环境试验数据,为生产设计部门
Large-scale environmental tests of commonly used materials led and organized by the State Science and Technology Commission have been carried out for many years in eight trials at the 54 Central Station of the Ministry of Armaments, Hainan Station and Guangzhou, Qingdao, Beijing and Wuhan, respectively, after many years of preparations. Station cast test samples are China’s national economy in the amount of both large and widely used materials, including ferrous metals, non-ferrous metals, coatings, coatings, engineering plastics, such as more than 40,000 pieces of the sample period of 16 years Through the experiment on the accumulation of various materials in different environmental conditions, reliable environmental test data for the production design department
