| 摘 要： | 先秦时期城市的给水主要来源有两个,一是凿井取水,二是穿渠引水。井水水质纯净,渠水水量较大。城市的排水主要依靠管道将城中的雨水和生活废水排往城外的护城河中。

| Abstract: | The zirconium phosphate α-Zr（HPO4）2·H2O with layered structure is characterized by Power X-ray diffraction（XRD）,vibrational spectroscopy（FT-IR,FT-Raman）,thermal gravimetric analysis（TG）,transmission electron microscopy（TEM）,scanning electron microscopy（SEM）,and Brunauer-Emmett-Teller（BET） nitrogen adsorption.The specific BET surface area of α-Zr（HPO4）2·H2O is 12.29 m2·g-1.The cyclic voltammetry behaviors of the α-Zr（HPO4）2·H2O on Au electrode show a quasi-reversible process.The intercalation behavior of α-Zr（HPO4）2·H2O is investigated.The results of intercalation reactions with tetramethylammonium bromide and cetyltrimethylammonium bromide show interlayer distances increase of 0.46 nm and 1.68 nm,respectively.Moreover,the strong fluorescent properties of intercalation compounds are measured at room temperature. |
