为了提高块压缩感知的测量效率和重构性能，根据离散余弦变换和离散正弦变换具有汇聚信号能量的特性，提出了基于重复块对角结构的部分离散余弦变换（partialdiscrete cosine transform in repeated block diagonal structure，PDCT—RBDSl和部分离散正弦变换fpartial discrete sine transform in repeated block diagonal structure，PDST—RBDS）的两种压缩感知测量方法．所采用的测量矩阵是一种低复杂度的结构化确定性矩阵，满足受限等距性质．并得到一个与采样能量有关的受限等距常数和精确重构的测量数下限．通过与采用重复块对角结构的部分随机高斯矩阵和部分贝努利矩阵的图像压缩感知对比，结果表明，PDCT-RBDS和PDST_RBDS重构的PSNR大约提高1～5dB，SSIM提高约0．05，所需的重构时间和测量矩阵的存储空间大大减少．该方法特别适合大规模图像压缩及实时视频数据处理场合．

NH_(3)选择催化还原技术(NH_(3)-SCR)作为一种高效去除NO_(x)的手段,已广泛地应用到柴油车尾气脱硝过程当中。车用NH_(3)-SCR技术常采用铜基分子筛作为催化剂,尾气中的氮氧化物可在催化剂的作用下,与NH_(3)反应转化为N_(2);但在实际应用过程中,N_(2)O的生成、催化剂的水热老化与尾气中的SO_(2)会影响铜基分子筛催化剂的脱硝性能。因此,本文以Cu-SSZ-13分子筛催化剂中孤立态Cu^(2+)的研究进展为基础,总结了Cu-SSZ-13中两种孤立态Cu^(2+)对NH_(3)-SCR反应与N_(2)O生成的影响;综述了两种孤立态Cu^(2+)对水热老化与SO_(2)响应的差异;归纳了诱导Cu-2Z生成的手段。同时,本文以Cu-LTA分子筛催化剂的研究现状为例,简要回顾了Cu-LTA中孤立态Cu^(2+)的研究进展,对Cu-LTA的研究趋势与应用前景作出了展望。本文可为其他类型的铜基分子筛催化剂在柴油车尾气脱硝领域的研究提供思路,即明确分子筛中两种孤立态Cu^(2+)相关性质,通过调控孤立态Cu^(2+)对催化剂进行合理设计,在保持高催化活性的同时,进一步提升催化剂的水热稳定性与SO_(2)抗性。

目的提出一种利用轮廓信息对应关系计算空间变换的多尺度点云数据融合方法,准确获得兼顾大型钢桁梁主体以及局部螺栓孔的杆件点云信息,从而用于钢桁梁的虚拟拼装。方法首先,结合立式三维激光扫描和手持式三维激光扫描两种方式,分别获取表征大尺寸构件整体信息和螺栓孔群局部信息的点云数据;然后,基于点云数据分别提取融合部位的轮廓信息,并使用轮廓信息对应关系计算空间变换矩阵;最后,利用空间变换矩阵进行点云融合。结果通过主轴方向偏差和最近距离约束对融合后的模型进行融合效果评定,验证了融合方法的准确性;其中,主轴角度偏差量为0.0000384°、扭转角度偏差量为0.01175°、豪斯多夫距离为0.311 mm,满足工程要求。结论所提方法能够针对性的对具有一定规则性的杆件进行局部特征提取,简化了空间变换所需要的信息,为钢桁梁虚拟拼装提供了数据基础。
