优选法是利用数学上的一些方法和原理,指导我们在生产和科学实验中,以较少的试验次数,找到工业产品的最好配方和工艺条件以及科学实验的最优方案。优选法是唯物辩证法在数学领域内的一种体现,是运用毛主席光辉哲学思想解决质量控制和实验设计的具体例证。由于这种方法简单易懂、见效快、应用方便,所以很受广大工农兵群众的欢迎。一九七○年六月,华罗庚同志等在上海讲授和推广优选法以来,很多地区和部门已经推广应用。铸造战线的一些工厂和研究单位也在推广应用并取得一些成绩。下面介绍的是兰州铸造厂等单位应用优选法的经验。关于优选法本身的介绍,各地已印发了大量资料,本刊因篇幅所限,不再刊登。
The preferred method is the use of some mathematical methods and principles to guide us in production and scientific experiments, with fewer trials to find the best formula for industrial products and process conditions and the best scientific experiments. The preferred method is a kind of embodiment of materialist dialectics in the field of mathematics, and is a concrete example of using the glorious philosophy of Chairman Mao to solve the quality control and experimental design. Because of this method is easy to understand, quick, easy to use, so very popular with the broad masses of workers, peasants and soldiers welcome. In June 1970, Comrades Hua Loeng Geng and others promoted and applied the Law of Choice in Shanghai. Many regions and departments have already promoted their application. Some factories and research units in the casting front are also promoting their applications and achieving some results. The following is the Lanzhou foundry and other units of the application of the preferred method of experience. As for the introduction of the preferred law itself, a great deal of information has been printed in various places. Due to the limited space, this publication is no longer published.
