One of the most powerful functions of Geographic Information System for Transportation (GIS-T) is Dynamic Segmentation (DS), which is used to increase the efficiency and precision of road management by generating segments based on attributes. The road segments describing transportation data are both spatially and temporally referenced. For a variety of transportation applications, historical road segments must be preserved. This study presents an appropriate approach to preserve and retrieve the historical road segments efficiently. In the proposed method, only the portions of segments of a time stamp that have been changed into new segments rather than storing the entire segments for every old time stamp are recorded .The storage of these portions is based on the type of changes. A recursive algorithm is developed to retrieve all segments for every old time stamp. Experimental results using real data of Tehran City, Iran justify the strength of the proposed approach in many aspects. An important achievement of the results is that database volume for 2006, 2007 and 2008 within the Historical Line Event Table (HLET) is reduced by 70%, 80% and 78%, respectively. The proposed method has the potential to prevent from vast data redundancy and the unnecessary storage of entire segments for each time stamp. Since the present technique is performed on ordinary plain tables that are readable by all GIS software, special software platforms to manage the storage and retrieval of historical segments are not needed. In addition, this method simplifies spatio-temporal queries.

采用十二烷基硫酸钠(SDS)表面活性剂和SiO_(2)纳米颗粒作为发泡体系,在不同原油沥青质含量下进行泡沫稳定性实验,测量CO_(2)泡沫半衰期;采用扫描电子显微图像、紫外分光光度法测试和Zeta电位测量,分析沥青质降低CO_(2)泡沫稳定性的机理。研究表明:当合成油与发泡体系质量比为1∶9时,合成油沥青质质量分数从0增至15%,SDS稳定泡沫半衰期从751 s减少至239 s,SDS-SiO_(2)稳定泡沫半衰期从912 s缩短至298 s;当合成油与发泡体系质量比为2∶8时,随着沥青质质量分数增大,SDS稳定泡沫半衰期从526 s缩短至171 s,SDS-SiO_(2)稳定泡沫半衰期从660 s缩短至205 s。由于沥青质与SDS和SiO_(2)纳米颗粒在水相中的相互作用,Zeta电位绝对值减小,颗粒表面电荷降低,导致薄液膜两侧界面之间的排斥力减小,从而破坏泡沫稳定性。
