每个产品另件功能的实现,不但需要具有一定的外形尺寸、精度,而且更需有相应的材料来承担其机械、物理及力学性能,这样才能完满实现产品另件的功能要求。因此,任何产品都需要研究材料的选用,而任何一种材料的产生都需要经过一定的科学研究,才能研究出材料的适用范围和应用价值。过去在材料研究工作中,往往偏重于材料的实用功能,而忽视了成本高低。通过应用价值分析方法研究新材料,不但可以研究出满足功能要求的新材料,而且成本较低,做到技术与经济结合,用户与生产企业结合,设计出物美价廉、经济实惠的新材料,大大降低产品成本,可以说价值分析法在材 The realization of the function of the other parts of each product not only requires certain dimensions and precision, but also requires corresponding materials to bear the mechanical, physical and mechanical properties so as to fulfill the functional requirements of the other parts of the product. Therefore, any product needs to study the selection of materials, and the production of any kind of material requires some scientific research to study the application of the material and application value. In the past, materials research often tended to emphasize the practical function of materials while neglecting the cost. By applying the method of value analysis to study new materials, not only new materials that meet the functional requirements can be researched, but also the cost is low, the combination of technology and economy, the combination of users and manufacturing enterprises, the design of new material with low cost and economic benefits, Greatly reduce product costs, we can say that value analysis method in the material
