摘　　要：本文借助红外、紫外光谱等研究方法,采用新的氯甲酸甲酯衍生预处理技术,利用气相色谱-质谱联机(GC-MS),对经过加压酸煮的褐煤液体进行快速有效地成分分析检测。从而对Collins等人将煤应用于闪锌矿加压浸出中煤的作用机理作了进一步的解释。Depending on IR, UV analytical instruments, as methyl chloroformate derivatives using gas chromatogramphy - mass spectrometry, the liquor from lignite which is pressurized and cooked with acid can be analyzed fleetly and effectively. It is used to explain ulteriorly the mechanism that coal is applied in the pressure leaching of the marmatite concentrates by Collins.
