在大学毛主席著作的高潮里,河南黄河职工通过学习,联系实际,创造出了用木竹筏作为探摸险工根石的一种工具。过去用木帆船探摸根石,投资大,每天需开支船工工资四十元左右,操作又不够安全。采用木竹筏以后,每天平均投资仅需四元左右,探摸根石的准确程度和操作安全方面都有很大提高。因此我们认为它是一项重要的革新。 At the climax of Chairman Mao’s work at the university, the workers of the Yellow River in Henan Province, through learning and practicing, created a tool to use wooden bamboo rafts as a root cause for exploration workers. In the past, we used wooden sailboats to explore the root stone, and invested a large amount of wages. The daily wage of sailors was about $ 40 and the operation was not safe enough. After using bamboo raft, the average daily investment is only about four yuan, the accuracy of exploration of root stone and operational safety have greatly improved. So we think it is an important innovation.
