Throughout years,the two-step spin-coating process is the most common method to prepare organic lead halide perovskite ***,the short reaction time of dropping the solution at the second step means that PbI2 cannot be completely transformed into perovskite *** solve this problem,we report the introduction of glycine hydrochloride(GlyHCl)into the second step of the two-step spin-coating process to prepare a fa.(0.9)MA_(0.1)PbI_(3-x)%-GlyHCl perovskite material(namely fa.A-x%-GlyHCl,where fa.formamidinium,MA=methylammonium,and x%stands for the molar ratio of GlyHCl added in fa.iodide/MA iodide(fa./MAI)precursor solution).The Cl−ion in GlyHCl assists the formation ofα-phase perovskite,and the-COO−group coordinates with Pb2+cation in a bridging way,making up for the anion vacancy in perovskite lattice and resulting in high absorption *** perovskite solar cells(PSCs)based on fa.A-9%-GlyHCl achieve a long carrier lifetime(527.0 ns),a photoelectric conversion efficiency(PCE)of 19.40%and good thermal stability,maintaining 85.8%of the initial PCE after being continuously heated at 60℃for 500 *** study helps to solve the problem of incomplete reaction in the two-step spin-coating process and puts forward a new solution for preparing high coverage perovskite films with large grain size.

Using a convective scale WRF-GSI system and a reﬂectivity observation operator based on the double-moment microphysics(Thompson)scheme,simulated radar reﬂectivity data are produced and then directly assimilated with EnKF through Observing System Simulation Experi-ments(OSSEs)for the case of typhoon In-fa.2021).We examined the ability of the EnKF to simultaneously estimate state variables and conducted sensitivity tests to evaluate the impact of updating different state *** results show that updating a full set of analysis variables can help obtain highly precise initialﬁelds in the model and improve typhoon forecast *** the horizontal wind update will affect the adjustment of the temperatureﬁeld and the sea level pressureﬁeld during the cyclic assimilation *** the variables directly related to the reﬂectivity operator alone could adjust hydrometers well,but the positive impact arising from the assimilation quickly vanishes during the *** addition,this study also includes a quantitative RMSE analysis for each variable during the assimilation cycle and compares the effect of each schemes on different variables.

超声波的相位变化携带着组织结构的重要信息,通过相位加权可提高超声图像的清晰度.针对褶皱散射回波微弱、受噪声影响大、时域修正成像耗时长等问题,提出一种基于相位虚部相干因子的频域相干成像方法.首先提取波场信号中的相位信息,然后采用环形统计获取相位虚部矩阵,通过相位虚部矩阵与相位迁移成像(phase shift migration,PSM)中的原频域矩阵相乘构建相位虚部相干因子(phase imaginary coherence fa.tor,PICF),将相位虚部相干因子引入相位迁移成像,并对各层迁移波场进行修正,通过频域信号相乘恢复纤维纹理信息.对厚度为18 mm的碳玻纤维复合材料板进行检测,实验结果表明:未加权的相位迁移成像在10 mm深度以后的纤维铺层信息丢失,无法检测出深层区域的缺陷;用PICF加权后PSM成像可检测出位于11,15,16 mm处的3个纤维褶皱,褶皱缺陷成像清晰度和纹理细致度均得到提高,褶皱角度的检测误差约为10%,并且成像耗时仅为1.5 s,运算效率比时域全聚焦成像(total focusing method,TFM)至少提高8.67倍.

以上海黄浦江某越江大桥在方案研究中提出的自适应锚碇基础为背景，针对埋置于砂土地基中的自适应锚碇基础开展了离心机模型试验，分析了主缆拉力作用下锚碇的侧土压力分布及变位规律，探讨了偏心填土对锚碇稳定性和变位的影响。研究结果表明：锚碇在主缆拉力作用下呈现绕侧面趾部的旋转变位模式，靠近锚拉点一侧受主动土压力作用，远离锚拉点一侧受被动土压力作用，两侧的土压力差能够提供一定的水平抗力。锚碇基础承受主缆拉力作用时，其主要的变位模式为转动变位，刚性水平变位对锚碇整体变位的贡献较小；偏心填土显著减小了锚碇的水平变位，有利于提高锚碇抗倾覆稳定性与变位控制。研究结论对于自适应锚碇基础的理论分析和工程设计具有参考价值。
