从严格意义上讲在科学研究、新产品开发上,我国很少有真正从事工程机械研究的实验室,由此产品发展主要是依靠引进技术,仿制、测绘国外产品,稍加改进进行国产化。那么,我国筑养路机械技术水平提高的着眼点在哪里呢…… Strictly speaking, in scientific research and new product development, there are few laboratories in our country that are really engaged in the research of construction machinery. Therefore, the development of our products mainly relies on the introduction of technology, imitation, surveying and mapping of foreign products and domestication with a slight improvement. So, where is the focus of raising the level of mechanical technology in our country?
