    太阳能光伏发电作为解决能源危机与环境问题的有效途径,在世界范围内得到快速发展。太阳能因其分布广泛、用之不竭而成为人们重视的焦点,其最主要的利用方式是太阳能电池。近年来利用有机铅卤化物钙钛矿作为活性层制备的钙钛矿太阳能电池受到了科学工作者关注,进而出现了大量的创新性研究成果。 钙钛矿太阳能电池(PSCs)具有制备工艺简单、可溶液法制备、能量转换效率高等优点。在PSCs结构中,空穴传输层(HTMs)能够保证有效电荷的提取和传输,因此HTMs一直是PSCs中不可缺少的部分。目前应用在钙钛矿电池中的空穴传输材料分为无机类HTMs,聚合物类HTMs和有机小分子类HTMs。虽然无机类HTMs空穴迁移率高...As an effective solution to energy crisis and environment pollution, solar photovoltaics (PV) is developing rapidly worldwide.

    真核细胞生物体中,核受体是非常重要的一类蛋白质,调控着诸多生物学功能。本研究主要以核受体RXRα作为研究对象。 RXRα是核受体家族中主要的一员,能够介导多种生物学功能,包括体内稳态、代谢平衡、细胞分化和细胞凋亡等功能,同时RXRα在肝脏中是高度表达的,在肝纤维化过程中,RXRα的表达下调。以此为基础,本研究发现RXRα配体K-80003能够起到抑制肝纤维化的作用,希望能通过K-80003来解释RXRα是如何参与肝纤维化的调控。本研究发现,K-80003在细胞水平上可以抑制肝星状细胞的活化,降低细胞外基质的产生;在动物水平上K-80003可以改善CCl4诱导的肝损伤和由肝损伤引发的肝纤维化;...In eukaryotic organisms, nuclear receptor is a very important class of proteins, regulating a variety of biological functions.

    电梯在高层建筑中使用频繁,并且容易发生安全事故,因此,人们在追求速度的同时,更多的是关注电梯的安全性能。电梯超载限制装置一般是通过重力传感器的测量以确定是否超载。一旦重力传感器出现问题,可能会导致重大的安全事故。因此,在提高重力传感器性能的基础上,通过控制乘梯人数来加强电梯超载限制装置的安全性能。另外,目前很多电梯都限定了乘梯人数,在安全载重范围内,乘梯人数过多会降低乘梯的舒适度,并且过度拥挤同样会引发安全事故。 本文着眼于在上位机上研究如何快速准确的检测出电梯轿厢内视频监控图像中的人脸数,并依此得出人数。因此,将人数统计问题的研究间接地转化为对人脸检测问题的研究。 首先简单介绍了本课题的...With the continuously economic improvement of the modern society, more and more high-rise buildings come out from the ground, which makes a rapid progress of the elevator industry.

    摘要 我国目前的钢筋混凝土梁-板设计理论仍沿用“边支承板”的观念。有限元弹性分析表明,在梁板结构中,梁、板所承担的弯矩在很大程度上取决于梁和板的刚度比。按照“边支承板”设计的楼板与实际楼板的受力特点有较大的差异,特别是在梁板刚度比较小的情况下,如宽扁梁结构。 本研究采用大型有限元软件ANSYS提供的SOLID65单元和LINK8单元,探讨并建立了符合钢筋混凝土梁—板结构特点的非线性有限元模型,并通过与文献[44]模型试验数据的对比分析表明,选择合适的计算分析参数,ANSYS可以较为真实的模拟钢筋混凝土梁-板结构的受力性能。 计算分析模型为一层双向等柱距3跨×3跨钢筋混凝土梁-板结构(...ABSTRACT At present, we still use the concept of “beam support slab”to design reinforced concrete beam-slab structure.

    可分离的下三角双线性模型是一类既具有广泛性又具有良好概率结构的双线性模型,简记为"SLTBL模型".本文采用Bayes方法对可分离的下三角双线性模型进行了统计分析.通过设置合理的先验,得到了各个参数的联合后验密度,进而导出了所有参数的条件后验分布.我们利用Gibbs抽样器方法抽取后验密度的样本,以对参数进行统计推断.特别地,由于从模型的方向向量的条件后验分布中直接抽样是困难的,我们特别设计了一个简单有效的Metropolis-Hastings算法以解决该难题.进一步,我们采用逆跳MCMC技术,以解决模型的定阶及子集选择问题.我们用仿真例子演示了本文所建议的方法,并应用于分析实际数据.Markov chain Monte Carlo (MCMC) technique is used to make Bayesian inference for seperable lower triangular bilinear models, a more general model class in time series analysis.
