基于1981—2020年塔里木河流域“四源”5个水文站的日径流数据及格网温度、降水和雪深等数据,采用最大值及POT采样法,分析洪水发生量级、频率和峰现时间等特征,同时采用相关性分析揭示不同洪水指标与影响因素之间的关系并识别关键影响因子。结果表明:(1)1981—2020年塔里木河“四源”各站点洪峰流量大小依次为:卡群>协和拉>同古孜洛克>沙里桂兰克>大山口,年及季节尺度洪峰流量普遍呈增加趋势,冬季洪峰发生时间均呈提前状态,其中沙里桂兰克年均提前最多为2.61 d,卡群站提前仅0.67 d。(2)研究时段内塔里木河流域共有2个洪水高发期,为1994—2002年和2006—2011年,流域内大量级洪水集中发生在1990年之后。(3)洪水发生前不同时间内最小温度、降水和雪深以增加趋势为主;而最大温度以减少趋势为主。春季洪水指标与最大3 d降水的相关性最高,而秋季洪水指标与最大7 d降水的相关性最高。相比于单日降水,多日降水与洪水指标的相关性更高。在雪深相关因子中,最大15 d雪深与各站点的春季洪水指标相关性最高。研究结果对区域水资源管理以及洪水灾害预测提供理论依据。

从水化过程、力学性能、收缩性能等方面系统研究了2种水玻璃对苯丙乳液(sa乳液)改性碱激发矿渣(AAS)性能的影响及其作用机理,以期指导sa乳液在AAS中的应用.结果表明:钾水玻璃(PWG)加速矿渣水化进程的能力强于钠水玻璃(SWG);sa乳液不影响AAS的水化进程,不会阻碍水化硅酸钙/水化硅铝酸钙的生成,但会抑制水滑石的生成;sa乳液显著降低了AAS的抗压强度,并且对PWG激发AAS的影响强于SWG激发AAS;AAS的抗折强度随着sa乳液掺量的增加呈先增大后减小的趋势,在SWG与PWG激发AAS中,sa乳液的最佳掺量分别为2.5%与5.0%;PWG激发AAS在14d内的总变形量高于SWG激发AAS,sa乳液可显著降低硬化浆体的总收缩量.

PVC was subjected to a chemical modification aiming at replacing the chlorine atoms by pyridine groups via a homolytic route. Pyridine groups were peculiarly affixed to the PVC matrix via a carbon-carbon bond rather than a carbonnitrogen one. PVC was first iodinated using the Conant-Finkelstein reaction, followed by the application of the homolytic conditions of Minisci to generate pyridinated PVC with a varying degree of substitution. The extent of substitution was not high; the reaction on 30% iodinated PVC afforded a degree of modification no greater than 3%.

Chloromethylation of polystyrene （PS） with two different chloromethylating systems methylal/thionyl chloride and paraformaldehyde/trimethylchlorosilane was studied. Soluble chloromethylated polystyrene with a degree of substitution of 89% was obtained. The Conant-Finkelstein reaction on the chloromethylated PS afforded soluble iodomethylated polystyrene with a degree of substitution as high as 96%. The reaction conditions of Minisci were employed to radically pyridinate PS via its iodomethylated derivative. Polyelectrolytes were formed which could be converted to normal polymers by treatment with a 20% aqueous solution of NaOH.
