摘要
分析了基于B/S结构的GPRS/Web GIS远程油烟监控系统的技术基础,设计了系统的油烟监控终端、客户端浏览器、监控中心、第三方Web GIS服务器、Internet网络和GPRS网络的拓扑结构,并讨论了该系统采用J2EE的方案实现B/S系统架构、GPRS数据的可靠传输、系统中应用Google Earth等问题。
The dimethyl phthalate,diethyl phthalate,dibutyl phthalate,benzyl butyl phthalate,di-2-ethyl hexyl phthalate and dioctylphthalate in the water were determined by dispersive liquid-liquid microextraction/gas chromatography with extraction solvent of carbon tetrachloride and dispersive solvent of acetonitrile.The optimized tests produced the following results： a good linearity in range from 1.00 μg/L to 100 μg/L of the six PAEs,detection limits of the method 0.18 μg/L～2.5 μg/L,RSD of standard solution≤6.1%;spiked recoveries of water samples from BaiYang Lake 70.9%～119%.
