引进先进技术并消化、创新是技术落后国家赶超先进国家的捷径,日本的发展过程就充分证实了这一点。我们国家要想改变落后的面貌,也必需走这条道路。改革、开放的政策就要求我们这样去做。我们从七十年代末加强技术引进以来,取得了很大的经济效益,在技术上也推进了一大步。就我们铸造行业来看,常温固化树脂砂设备和工艺的引进,亨特造型机的引进和研制以及近年来气流冲击造型机的研究和引进,这些新东西的出现,对我国铸造行业都将是一次深刻的大变革,使我们铸造行业进入一个新的阶段,取得了较好的经济效益,但从宏观上来看,仍然存在不少问题。
The introduction of advanced technologies and their digestion and innovation are the shortcuts for backward countries in backward countries to surpass advanced countries. The development of Japan fully confirmed this point. If our country wants to change its backwardness, it must also take this path. Reform and opening up policies require us to do the same. Since we strengthened the introduction of technology from the late 1970s, we have achieved great economic benefits and have taken a big leap forward in technology. In our foundry industry, the introduction of room temperature curing resin sand equipment and processes, the introduction and development of Hunter molding machine and air impact molding machine in recent years, the study and introduction of these new things, the foundry industry in China will be A profound reform, so that we foundry industry entered a new stage, and achieved good economic returns, but from a macro point of view, there are still many problems.
