摘　　要：对宝钢混匀矿质量评价的主要不妥之处进行了分析,着重提出了利用假设检验来评价混匀矿质量的建议和细化的方案。The processing of blending - ore has been relatively complete in Baosteel, but the now - using evaluation of blending - ore quality is not enough scientific. The paper analyses the improperness on the evaluation and brings out a piece of advice on the new evaluation by method of hypothetical test.
