Imaging detection of composite plates is presented based on reconstruction algorithm for the probabilistic inspection of damage(RAPID) and double-turn coil omnidirectional shear-horizontal wave magnetostrictive patch transducer(OSH-MPT) array. The lowest shear-horizontal mode(SH) can propagate in the composite plate through bonding double-turn coil OSH-MPT. RAPID can realize using the direct wave of SH mode to extract the damage information. It is beneficial to detect composite plate in the case that the velocity of direct waves varies with the propagation direction. A small mass which is circular cylinder is bonded to simulate damage. Imaging results are achieved after using modified methods for eliminating the influence of the uneven probability distribution of the array(UPDA) in RAPID. Threshold is selected based on the receiver operating characteristic(ROC) curve for improving RAPID-based imaging accuracy.

为解决板式橡胶支座连续梁桥在强震作用下可能发生支座滑动进而产生桥梁碰撞、甚至落梁的问题,基于ANSYS平台建立了某板式橡胶支座连续梁桥的有限元模型,进行地震反应时程分析,研究了地震动峰值加速度(PGA)与峰值速度(PGV)的比值(fg)对桥梁板式橡胶支座滑动效应的影响,并给出了相对不利地震动输入方式.在相对不利地震动输入下,引入拉索减震支座进行减震研究,并对该支座的拉索刚度和初始间隙进行参数敏感性分析.结果表明,fg在一定程度上能够表征地震动频谱特性,板式橡胶支座的滑动能力与支座位移随fg的减小而增大;在相对不利的fg较小的地震作用下,拉索减震支座具有良好的限位能力,合理设置拉索刚度和初始间隙能有效防止桥梁碰撞、落梁等灾害.

利用有限元软件ANSYS,采用振型分解反应谱法和时程分析法分别计算了大型预应力贮煤筒仓结构的动力特性.研究表明:筒仓结构在质量和刚度分布上具有很好的轴对称性,无论是在满仓还是空仓工况下,第一、二阶振型均是自由振动的主要振型,且应力最大值均位于仓顶边缘设备集中荷载布置处,贮料能够显著降低筒仓结构的自振频率,对筒仓结构的动力特性影响极大.满仓地震时筒仓结构的变形和最大应力均比空仓地震时大,因此满仓状况下对筒仓结构抗震较为不利;在同一工况下采用振型分解反应谱法计算的仓顶最大位移和筒仓最大应力均大于时程分析法计算的结果.

A simple and sensitive method for determination of three aconitum alkaloids and their metabolites in human plasma was developed using matrix solid-phase dispersion combined with vortex-assisted dispersive liquid-liquid microextraction and high-performance liquid chromatography with diode array detection. The plasma sample was directly purified by matrix solid-phase dispersion and the eluate obtained was concentrated and further clarified by vortex-assisted dispersive liquid-liquid microextraction. Some important parameters affecting the extraction efficiency, such as type and amount of dispersing sorbent, type and volume of elution solvent, type and volume of extraction solvent, salt concentration as well as sample solution pH, were investigated in detail. Under optimal conditions, the proposed method has good repeatability and reproducibility with intraday and interday relative standard deviations lower than 5.44 and 5.75%, respectively. The recoveries of the aconitum alkaloids ranged from 73.81 to 101.82%, and the detection limits were achieved within the range of 1.6-2.1 ng/mL. The proposed method offered the advantages of good applicability, sensitivity, simplicity, and feasibility, which makes it suitable for the determination of trace amounts of aconitum alkaloids in human plasma samples.

Green determination of aconitum alkaloids in Aconitum carmichaeli (Fuzi) by an ionic liquid aqueous two-phase system and recovery of the ionic liquid coupled with in situ liquid-liquid microextraction

ANALYTICAL METHODS 2016年第35期8卷 6566-6572页

作者： Wang, Xiaozhong Li, xuwen Li, Lanjie Li, Min wu, Qian Liu, Ying Yang, Jie Jin, Yongri Jilin Univ Coll Chem Changchun 130012 Peoples R China Ningxia Univ Sch Chem & Chem Engn Yinchuan 750021 Peoples R China

A green and effective extraction system based on the use of an ultrasound-assisted ionic liquid aqueous two-phase system (IL-ATPS) was developed for the determination of aconitum alkaloids in lateral roots of Aconitum carmichaeli Debx (Fuzi in Chinese). IL-ATPS parameters, including the type and amount of ionic liquid, amount of salts, and pH value, as well as extraction time, were investigated. Under the optimized conditions, the recoveries of the analytes varied from 80.37 to 107.18%. The detection limits and quantification limits for the analytes were achieved within the ranges of 0.048-0.082 mg g(-1) and 0.16-0.30 mg g(-1), respectively. After extraction, the recovery of ionic liquids without the use of organic solvents was also confirmed. The hydrophilic ionic liquids (1-hexyl-3-methylimidazolium bromide) were converted into hydrophobic ionic liquids (1-hexyl-3-methylimidazolium hexafluorophosphate) by a metathesis reaction, and in situ liquid-liquid microextraction was triggered simultaneously. Finally, 0.1 mol L-1 HCl aqueous solution (containing 5% Tween-20) was used as the back-extraction agent to recover the ionic liquids.
