随机光学重建显微术（STORM）基于免疫荧光标记技术，具有原理易懂、光路简单、分辨率极高等特点，一直受到科研工作者的青睐，但分辨率的提升对抗体的特异性提出了更高的要求。相较一抗直接标记，“一抗+二抗”的间接标记法在实际应用中普适性更强。二抗相对一抗存在物种特异性的问题，生产时需要对其进行预吸附来提升物种特异性。为了探究二抗物种特异性对双色STORM成像的影响，基于经典的红细胞骨架模型中血影蛋白N端和C端的互斥位置关系，对二者使用高、低吸附二抗标记后分别进行双色STORM成像，对照模拟中有无信号串扰条件下的互相关分析结果，结果表明低吸附二抗会造成二者共定位的假象。进一步，分别通过高、低吸附二抗对MDA-MB-231乳腺癌细胞CD47和PD-L1两种膜蛋白进行双色STORM成像，结果揭示两种蛋白无共定位关系。本研究为二抗物种特异性的评估提供了一种基于红细胞骨架结构模型的超分辨成像新策略，助力双色STORM成像精准阐明蛋白分子互作关系。

民航自助行李托运系统需自动检测行李加装托盘的情况。针对已装载行李的遮挡托盘目标检测问题，提出一种基于多层骨架模型的行李托盘快速检测算法。为准确描述托盘特征，通过空托盘的三维点云模型，构建托盘的边框骨架模型与平面点线模型。在线检测时，首先，采用设计的带状特征描述和提取方法，抓取托盘边框点云，并采用提出的点线引力势能自适应迭代算法，实现平面点线模型的快速粗配准，完成托盘判别。然后，在粗配准的位姿约束下，采用基于随机采样一致性的点云迭代最近点配准，实现边框骨架模型和点云模型的精确配准，得到托盘的精确位姿。大量实际行李托盘检测的对比试验验证了算法的有效性，在托盘遮挡70%以内时，仍可保持94%的正确率，检测速度超过典型算法的6倍以上。

采用冰模板法构筑具有层状结构的Al2O3三维网络骨架, 并通过真空浸渍工艺制备出Al2O3/环氧树脂(EP)复合材料。研究了楔形硅橡胶角度、浆料固相含量、冷冻温度对层状Al2O3三维网络骨架微观结构的影响, 分析了片层间距对Al2O3/EP复合材料导热、介电和绝缘性能的影响。结果表明: 楔形硅橡胶角度为10°和15°时Al2O3三维网络骨架的层状有序性最佳, 固相含量的增加和冷冻温度的降低均会使片层间距减小; Al2O3/EP复合材料的热导率和介电常数随着片层间距的减小而增大, 但体积电阻率呈降低趋势; 当片层间距为45 μm时, 热导率达到0.52 W/(m·K), 体积电阻率为1012 Ω·cm。

成熟人红细胞膜骨架是由膜下多种蛋白组成的三角晶格网状结构，在维持红细胞形态、变形性、运动和代谢等功能方面扮演着重要角色。单分子定位超分辨成像（SMLM）技术在解析骨架超微结构方面展现出了强大的能力，但分辨率的提升对成像分析手段提出了更高要求。作为一种常用的空间分析方法，Vorono?分割在SMLM图像聚类分析中已被广泛应用。笔者利用自主搭建的SMLM超分辨成像系统获得红细胞膜蛋白和骨架蛋白的超分辨点簇图像，对点簇质心进行Vorono?分割，并对Vorono?多边形面积分布进行伽马函数拟合，发现自由膜蛋白CD59的伽马分布峰值对应的x轴坐标x_peak为0.78。结合模拟结果，验证了自由膜蛋白CD59呈随机分布。进一步，肌动蛋白、血影蛋白N端和原肌球蛋白的Vorono?分析结果显示它们的x_peak均为0.86，而锚蛋白的x_peak为0.84，说明骨架膜蛋白呈相对均匀的分布状态，但锚蛋白较其他骨架蛋白更具随机性。Vorono?方法可助力阐释红细胞膜骨架蛋白的空间分布特性，同时也为点簇状SMLM超分辨图像数据的深入提取提供了新思路和新方法。

In this paper, a comprehensive study of microstructure/properties interrelations for porous piezoceramics based on PZT composition was performed. Experimental samples of porous piezoceramics were fabricated using a modified method of burning-out a pore former. Porosity dependencies of elastic, dielectric, piezoelectric and electromechanical coefficients of the porous ceramics in the relative porosity range 0-50% were obtained and analyzed. As a result of microstructure analysis, it was found that at any connectivity type (3–0, 3–3) and porosity up to 50% the real structures of porous piezoceramics were close to the matrix medium structure with continuous piezoceramic skeleton. It was also revealed that the microstructural features of porous piezoceramics define the character of the dependences of the dielectric, piezoelectric and electromechanical properties of porous piezoelectric ceramics on porosity. In conclusion, microstructure/properties interrelations, as well as new applications of porous piezoceramics were discussed.In this paper, a comprehensive study of microstructure/properties interrelations for porous piezoceramics based on PZT composition was performed.
