在生产斗争和科学实验中,经常遇到这样的问题:怎样选取合适的配方,合适的操作条件,使产品的质量最好,成本最低,生产周期最短。过去,为要解决这个问题,工矿企业和科研部门,往往要耗用大量的人力、物力和时间,而且找到的配方和操作条件未必能取得最好的效果。“优选法”是一种指导安排实验的科学方法。用了它,可以做最少的实验,迅速找到最合适的配方和操作条件,从而达到多快好省的目的。
In the production struggle and scientific experiments, we often encounter such problems: how to choose the right formula, the right operating conditions, so that the best quality products, the lowest cost, the shortest production cycle. In the past, in order to solve this problem, industrial and mining enterprises and scientific research departments often consumed a lot of manpower, material resources and time, and found the formula and operating conditions may not be able to obtain the best results. “Law of preference” is a scientific method that guides the organization of experiments. With it, you can do the least amount of experimentation and quickly find the most appropriate recipe and operating conditions to achieve the goal of speed and economy.
