我厂是在无产阶级文化大革命中建成的一个新厂,大多数工人都是新工人,缺乏实践经验。在批林批孔运动中他们提高了觉悟。为了多洗煤,洗好煤,他们成立了一个试验组。经四川大学数学系同志的推荐,试验组同志将正交试验设计的方法应用于跳汰机选煤。此法可以减少试验次数,每一个选定的水平都可以互相配合一次,试验结果的数据在进行分析时有密切的联系,借用统计分析的方法,可以找出主要的矛盾和各个因素中最佳水平。只
Our factory is a new factory built during the Great Proletarian Cultural Revolution. Most of the workers are new workers, lacking in practical experience. They raised their consciousness in the pro-Lin hole movement. In order to wash more coal and wash coal, they set up a pilot group. Based on the recommendation of comrades of Mathematics Department of Sichuan University, the experimental group comrades applied the method of orthogonal experiment design to the jig coal preparation. This method can reduce the number of tests, each selected level can cooperate with each other, the test results of the data in the analysis are closely linked, borrowing statistical analysis methods, you can find the main contradictions and the best of each factor Level. only
