現代科学技术的发展十分迅速,苏联的地球人造卫星和太阳系人造行星的发射成功,标志着人类开始跃进到了遨游太空的时代。这一連串的尖端科学技术成就,和它們的进一步发展,必将越来越多地向机械制造提出更高更新的要求。在当前的形势下,机器构件要向适应高参数运行的方向发展,材料要能在高速、高温、高压下正常工作,而且还必須重量輕,
The development of modern science and technology is very rapid. The success of the launch of the artificial satellites of the Earth and the solar system in the Soviet Union marks the beginning of humankind’s leap into space. This series of cutting-edge scientific and technological achievements, and their further development, will increasingly be more and more new to mechanical manufacturing requirements. Under the current situation, the machine components should be developed to adapt to the operation of high parameters, the material should be able to work under high speed, high temperature and high pressure, but also must be light weight,
