在探寻高效简捷的列车造型优化设计方法方面,我国工程技术人员进行了有效的技术创新高速铁路的发展对我国国民经济发展和社会进步起着至关重要的作用。国际上,以日本和一些欧洲国家为代表的发达国家在高速铁路领域已经进行了大量的科学研究,积累了丰富的理论知识和经验,不断研发出新型的高速列车,且速度越来越快。京沪高铁的开通运行,标志着我国拥有自主知识产权的高铁技术进入新的发展阶段。
In the search for efficient and simple train design optimization methods, our engineers and technicians have conducted an effective technological innovation. The development of high-speed railway plays an important role in our national economic development and social progress. Internationally, the developed countries represented by Japan and some European countries have conducted a great deal of scientific research in the field of high-speed railway. They have accumulated rich theoretical knowledge and experience and continuously developed new high-speed trains at an accelerated pace. The opening and operation of the Beijing-Shanghai high-speed railway signify that China’s high-speed railway technology with independent intellectual property rights has entered a new stage of development.
