A method for determination of basic nitrogen-containing compounds in mainstream smoke was established. In the condition of basic substance barium hydroxide powder and extractant chloroform, 18 basic nitrogen-containing compounds were analyzed by gas chromatography-selective ion monitored-mass spectrometry, such as pyridine, 2-methylpyridine, 2-methylpyrazine, quinoline and indole, etc.

在氢氧化钡碱性环境中，以三氯甲烷为萃取剂，采用气相色谱－选择离子监测－质谱法测定吡啶、2-甲基吡啶、2-甲基吡嗪、喹啉、吲哚等18种碱性含氮化合物。

Spent solutions were finally drained into a mixing trough forneutralization, and subsequently, calcium or barium hydroxide and flocculant were added. Precipitate producedsuch as calcium or barium sulfate, calcium fluoride were separated, and recovered water was obtained after pu-rified by ion-exchange column.

分析了铝合金生产工艺中各步骤的化学成分，根据分析结果将常温脱脂、碱蚀、出光、阳极氧化和封孔等不满足生产要求的溶液排放至混合槽内进行中和，再加入氢氧化钠和絮凝剂分离沉淀后，经离子交换柱，得到的回收水可返回生产槽重复使用。

A value -base map may provide some useful de script ion, but the principle-centered compass provides invaluable vision and direction.

有价值的地图可提供有用的信息，但是严谨的罗盘却为我们提供非常重要的指南和方向。

Chap I reviews the development of Li-Ion battery and its charger, and describes the content of this design.
