根据1976年7月在上海召开的弹性模量测量方法交流会委托,我们起草了“金属材料杨氏模量测量方法—悬丝耦合横振动法部颁标准”(草案),供各单位试行和讨论。为了帮助大家了解这一标准制订的目的和过程,以及各项技术条件规定的依据,特作如下说明。一、悬挂法标准制订的目的和过程 According to the commission meeting on elastic modulus measurement held in July 1976 in Shanghai, we drafted the “Standards for the Young’s Modulus Measurement of Metallic Materials - The Standard for the Promulgation of Yarn of Transverse Vibration Coupling of Suspension Wires” (draft) for trial implementation by all units discuss. In order to help you understand the purpose and process of formulation of this standard and the basis for the provisions of various technical conditions, we hereby make the following special explanations. First, the purpose of the suspension method and the process of setting standards
