摘　　要：介绍了可选性评定过程中可能存在的一些失真问题,通过拆分指标的方法对失真原因进行了分析,提出了自身见解,同时对涉及可选性及可选性曲线的相关其他问题进行了研究。以δ±0.1含量值作为判定可选性的标准,确是充分考量了轻重产品的错配情况,可以满足大部分煤质的需求。Some possible distortion problems in the process of optionality assessment are introduced,and the causes of distortion are analysed by splitting the indexes and their own insights are presented,while other problems related to optionality and optionality curves are studied.The use of theδ±0.1 content value as a criterion for determining selectivity does take into account the mismatch between light and heavy products,and can meet the needs of most coal qualities.

关 键 词：可选性 失真 突变 临界密度 邻近物含量
