Under acidic condition, the dimer diethyldithiocarbamate （D2） is formed on marmatite through the electrochemical adsorption of diethyl dithiocarbamate at 0 - 200 mV.

采用光谱分析、循环伏安及恒电位阶跃法，研究了乙硫氮在铁闪锌矿表面吸附的电化学行为及机理，该机理与浮选电化学的混合电位模型并不一致。

Flotation of the three pure sulfide minerals (named amesonite, marmatite and pyrrhppite) used different regeants, is discussed as to know how the useful part is separated from the ore. The flotation behavior of the three minerals is that in low pH value they have good buoyancy,while in high pH value they have bad buoyancy.

以大厂92号矿石中的脆硫锑铅矿、铁闪锌矿、磁黄铁矿为主要研究对象，研究它们在不同药剂条件下的浮选行为，基本查明了三种矿物浮选行为：在酸性条件下，三种矿物均有较好的可浮性；在强碱性介质中，三种矿物的可浮性都变差。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
