现代科学技术的发展有两个明显的动向:知识的密集型式和电子计算技术的广泛应用。就是说,科学技术的研究逐渐由分化转向综合,知识由分散趋向密集。个体发明创造活动转变为社会性的活动,甚至出现了国家规模级的研究活动。电子计算机渗透到各个领域,机械工程也进入了微观和高速计算时代。 There are two obvious trends in the development of modern science and technology: the intensive type of knowledge and the widespread application of electronic computing technology. That is to say, the research on science and technology has gradually shifted from differentiation to integration and knowledge from decentralization to intensiveness. Individual inventions and creative activities into social activities, and even appeared at the national scale research activities. Computer penetration into all fields, mechanical engineering has also entered the micro and high-speed computing era.
