目前已提出了许多取样模型,用于确定试样的最小重量。为了便于实际应用,模型应尽可能地简化。在此意义上应用得最广泛的是 P.M.纪(Pierre M.Gy)提出的概率模型。纪氏从1953年起就在许多论文中阐述了这一模型,并不断地给予发展。美国采矿工程师学会1985年出版的《选矿手册》(MineralProeessingHandbook)在取样一章中着重地介绍了这一模型,标志着纪氏模型已获得国际选矿界的广泛承认。
A number of sampling models have been proposed for determining the minimum weight of a sample. In order to facilitate the practical application, the model should be simplified as much as possible. The most widely used in this sense is the probability model proposed by Pierre M. Gy. Jerry has expounded this model in many papers since 1953 and continues to develop it. The Mining Institute of Handbook, published by the American Institute of Mining Engineers in 1985, introduced this model in a sampling chapter, highlighting that the discipline’s model has been widely recognized by the international dressing community.
