引言四个现代化,关键是科学技术现代化。对于文教战线和科技战线上的人来说,对农业战线作一点科学技术方面的改革也是为实现农业现代化而作的一点贡献。因此,遵照毛主席关于教育与生产劳动相结合和理论联系实际的教导,近年来,我们对农业战线的一个数学问题——量堆皮尺的研制问题,作了一些初步的探讨。粮收季节,往往也是农村社员很忙的季节,但是在处理谷场上成堆粮食的问题上却要花去很多年青力壮的劳力。社员们在估产、算产、入库和予分口粮前估算的时候,都要将成 Introduction The key to the four modernizations is the modernization of science and technology. For the people on the cultural, educational and scientific fronts, a little scientific and technological reform in the agricultural front is also a contribution made to the modernization of agriculture. Therefore, in conformity with Chairman Mao’s teaching on the combination of education and productive labor and on the theory and practice, in recent years we have made some preliminary discussions on the development of a mathematical problem on the agricultural front, the development of a measuring pile. The harvest season is also often a busy season for rural members, but many young and energetic workers are required to deal with the pile of food on the field. The members are expected to make an estimate when they estimate their production, their production, storage and pre-census
