A method was developed for the determination of tetraethyl ammonium （TEA） by reversed-phase ion- pair chromatography with indirect ultraviolet detection, Chromatographic separation was achieved on a reversed-phase C18 column using background ultraviolet absorbing reagent - ion-pair reagent - organic solvent as mobile phase. The effects of the background ultraviolet absorbing reagents, detection wavelength, ion-pair reagents, organic solvents and column temperature on the determination method were investigated and the retention rules discussed. Results found that TEA could be successfully analyzed by using 0.7 mmol/L 4-aminophenol hydrochloride and 0.15 mmol/L 1-heptanesulfonic acid sodium mixed with 20% （v/v） methanol as mobile phase at a UV detection wavelength of 230 nm. Under these conditions, the retention time of tetraethyl ammonium was 2.85 min. The detection limit （S/N = 3） for TEA was 0.06 mg/L. The relative standard deviations （n = 5） for peak area and retention time were 0.35% and 0.02%, respectively. The method has been successfully applied to the determination of synthesized tetraethyl ammonium bromide. Recovery of tetraethyl ammonium after spiking was 99.1%.

基于ABAQUS有限元软件为平台建立了FRP管-混凝土-钢管组合结构在低速侧向撞击荷载下的有限元计算模型,该模型计算结果与现有试验结果对比后吻合良好,能够较好地模拟FRP管-混凝土-钢管组合结构在侧向撞击作用下的性能。同时利用该模型进行了有限元参数分析,通过改变冲击能量和空心率来分析它们各自对该组合结构撞击性能的影响。得出的结论是冲击能量对该组合结构跨中极限挠度影响显著,但冲击力平台值却几乎不变;空心率对该组合结构抗撞击性能影响较大,尤其是当空心率在0.6~0.8范围内时组合结构展现出良好的抗撞击性能,且当空心率χ=0.7时,FRP管-混凝土-钢管组合结构表现出的抗冲击力学性能最好。这些研究对进一步开展FRP管-混凝土-钢管组合结构的抗撞击性能研究提供了一定的参考依据。

自2017年3月以来,中国多个城市相继出台了房地产限售政策。本文基于2017年1月至2018年5月的全国城市月度数据,针对限售政策分期出台的实际情况,构建更具适用性的多期双重差分模型(Multi-Stage Difference-in-Difference),分别从国家和城市层面实证分析了限售政策平抑房价的效果及其异质性。在此基础上,又对限售政策和限购政策的联合效应进行研究。研究结果表明:房地产限售政策能显著平抑房价且效果具有异质性。具体而言,在国家层面,限售政策对房价的平抑效果二手房强于新房、小户型强于中大户型;在城市层面,其平抑房价的效果一线城市强于二三线城市、中西部城市强于东部城市。此外,双限政策的联合效果优于单一限售政策。以上研究对进一步发掘限售政策的独特价值具有现实意义。
