材料技术是拖拉机工业的基础技术之一。合理选材,提高用材水平,有计划的研制适合拖拉机“三上一提高”的新材料是拖拉机行业材料技术工作的重要任务。 我们于1985年对全国37个拖拉机厂,17个拖拉机用柴油机厂和10个齿轮厂进行了用材现状调查,加上平时掌握的资料,现对我
Material technology is one of the basic technologies of the tractor industry. Rational selection of materials, improvement of timber levels, and the planned development of new materials suitable for the tractor’s “three-up and one-uplift” are important tasks for the material industry in the tractor industry. In 1985, we investigated the timber status of 37 tractor plants, 17 tractor diesel engine plants, and 10 gear factories across the country.
