摘　　要：通过对水相中细粒煤电动电位的研究，认为水相中表面荷负电的煤颗粒，其电性受ｐＨ值和某些化学药剂的影响比较大，且呈现出规律性变化。利用化学平衡和有关的吸附理论对此进行了理论探讨，并作出了合理的解释。It was found that the electro-property of coal particle which surface with negative electron in aqueous solution is affected much bigger by pH value and some of the chemical agents and present a regularity change through electromotive force research of fine coal in aqueous phase. A theory approach is made for it by absorbing theory and chemical balance, a reasonable explanation is also presented.
