中国路面机械发展30年

Development of China road machinery in the past 30 years

回顾近30年的发展历程,我国路面机械的发展可以大体上以10年为期划分为三个阶段:大规模引进国外技术的时期(20世纪80年代中期-90年代中期);在消化、吸收国外技术基础上的扩展时期(20世纪90年代);从复制国外技术逐步迈向自主创新的时期(进入21世纪后)。

The process of the development of China road machinery in the past 30 years divides into three phases:the first period of largescale introduction of foreign technology (from mid-1980s to mid-1990s);the second period of expansion based on the digestion and absorption of foreign technology (1990s);the third period of independent innovation instead of copying foreign technical(after 21st century).
