前言随着工农业生产和科学技术的迅速发展,国民经济各工业部门迫切要求提供具有极低频率温度系数、综合性能良好的恒弹性材料。为此,重庆仪表材料研究所研制了一种含Mo、Cu的新型恒弹性合金。毛主席教导我们:“真理的标准只能是社会的实践。”为了考核这种合金的性能、加强材料研究、生产、使用单位之间的联系和协作,仪表材料研究所的同志曾赴南京七
Preface With the rapid development of industrial and agricultural production and science and technology, various industrial sectors in the national economy are urgently required to provide constant elastic materials with extremely low frequency and temperature coefficients and good comprehensive properties. To this end, Chongqing Institute of Instrumentation Materials developed a new type of permanent elastic alloy containing Mo, Cu. Chairman Mao taught us: “The standard of truth can only be social practice.” In order to evaluate the performance of this alloy and to strengthen the links and collaboration among materials research, production and use units, the comrades of the Instrumentation Materials Institute went to Nanjing VII
