中世纪的铸剑师们反复地锤打、加热和淬火手中的材料,但他们并不真正懂得材料的物理、化学性质。他们的经验从师傅到徒弟一代一代地传下来,而且随时间的推移不断地丰富和提高。那时的材料生产技术进步是非常缓慢的。如今则不同了,许多地方已经实现了用计算机控制材料的生产。计算机程序中包含温度、压力等一组工艺条件。计算机使得材料生产技术获得了显著的成功,但对经验的依赖也 Medieval swordsmen repeatedly hammer, heat and quench the hands of the material, but they do not really understand the physical and chemical properties of the material. Their experience has spread from master to apprentice generation after generation, and constantly enriched and improved over time. At that time the material production technology is very slow progress. Nowadays the difference is that in many places, the production of computer-controlled materials has been realized. Computer program contains temperature, pressure and a group of process conditions. Computers have achieved significant success in material production technology, but also relied on experience
