一、材料强度与机械产品质量、节豹材料间的关系毛主席关于:“一切产品,不但求数量多,而且求质量好,耐穿耐用”的教导给我们指出了质量与数量的辩证关系。没有数量当然谈不上质量,有了数量之后,还要质量上去,数量才能发挥作用。机械产品的主要质量标志是:效能、寿命、重量/容量比等。其中,效能当然是首要的。在保证了效能以后,接着就要提出寿命和重量等质量问题。当前我国某些产品与国际先进水平的差距主要表现在:产品粗大笨重和寿命不长,钢材,特别是高级合金钢材的使用不尽合
First, the material strength and quality of mechanical products, the relationship between leopard material Chairman Mao on: “All products, not only for quantity, but also for good quality, durable wear-resistant” teaching to us that the quality and quantity of the dialectical relationship. Of course, there is no quantity to talk about the quality, with the quantity, but also the quality, the quantity can play a role. The main quality marks of mechanical products are: performance, life expectancy, weight / capacity ratio and so on. Among them, the effectiveness of course is the primary. After ensuring the effectiveness, then we must put forward the quality of life and weight issues. At present, the gap between some products in China and the international advanced level is mainly manifested in that: the product is bulky and bulky, its life is not long, and the use of the steel, especially the advanced alloy steel,
