利用运动姿态监测结果为舰船可靠航行提供决策依据。为此,设计了基于前端开发框架的舰船运动姿态数据监测系统。系统设施层中,利用MEMS陀螺仪芯片与3轴MEMS加速度计采集舰船运动姿态信息,并将所采集信息传送至业务逻辑层;业务逻辑层利用控制子层和管理子层为用户提供姿态数据监测服务;控制子层中的姿态解算模块,依据传感器信息采集结果,利用卡尔曼滤波算法解算舰船运动姿态信息。基于此,利用Bootstrap的前端开发框架,通过viewport元数据标签完成前端UI设计,为用户提供可视化的人机交互界面,将姿态解算结果利用用户界面层为用户展示。测试结果表明,该系统对舰船航行运动姿态的监测结果与实际结果极为接近,适用于实际工作。

为探索金属硫族团簇材料的多样性结构及其光电应用,利用溶剂热法,以含孤对电子的金属Sb(Ⅲ)与硫元素采用不对称的配位几何方式结合,合成了Sb基硫族团簇化合物[Sb_(4)S_(5)(S_(3))]·C_(5)H_(11)N(1)和(C_(5)H_(12)N)_(2)[In_(2)Sb_(2)S7](_(2))。2种化合物分别由{SbS_(3)}或{InS_(4)}配位单元之间以顶点共享的方式组合而成。电催化氧还原反应(ORR)研究表明,化合物2的极限电流密度和半波电位均高于化合物1,表明其ORR性能更好。Koutecky-Levich图分析表明,由混合金属构筑而成的层状化合物2的ORR催化过程以四电子路径为主。

基于中国家庭金融调查数据,采用Probit模型、Heckprobit模型、工具变量模型以及中介效应等模型,分析农户互联网使用对农地流转市场转型的影响及作用机制。研究发现:互联网使用打破了村庄熟人信任交易格局,促进了农地非熟人流转。机制检验结果显示,互联网使用通过提高信息获取能力、增强社会信任以及改善金融素养等路径,激励农户出于营利性动机与非熟人进行农地流转交易。异质性分析发现,使用移动互联网和户主中高受教育水平的农户家庭,互联网使用对其农地非熟人流转具有显著的正向影响,而对使用传统互联网和低教育水平农户家庭的影响并不显著。因此,应完善农村地区互联网基础设施建设,大力发展“互联网+农地流转”服务体系,重视农户互联网技能培训和文化水平提升,以有序推动农地流转市场转型。

为了提高简单立方(SC)点阵结构的平压力学性能,在ABAQUS中对SC单胞建立了周期边界约束方程,并通过ESO算法对周期边界条件下的SC单胞进行了拓扑优化设计。随后对优化SC单胞的等效弹性模量进行了求解,发现优化SC单胞的等效弹性模量明显优于传统SC单胞,从外部去除单胞材料可使优化单胞等效压缩模量提高27.14%,从内部去除单胞材料可使单胞等效剪切模量提高46.18%。最后将优化SC单胞从单胞层面扩展到宏观结构中,探究了三类SC点阵结构的静态平压性能。研究表明,周期边界条件与ESO相结合的拓扑优化方法,可使SC结构静态平压时的抵抗力得到明显提升。相比传统SC点阵结构,优化后的SC点阵结构抵抗力提高了20%以上。

乡村组织是国家治理体系的重要组成部分,乡村治理是国家治理的基本单元。当前,乡村治理主要依靠基层党组织这一主体,其发挥着领导作用,为实施乡村振兴战略提供坚强保障。进入新时代,我国城乡融合进程加快,农村社会深刻变革,但在部分乡村地区也存在农村基层党组织凝聚力不足、管理服务不到位、治理能力匮乏、党群关系疏离以及产业发展与经济引领能力欠缺等问题。因此,应深化党组织建设、推动三治融合、完善自治实践、加强法治教育、创新治理方式、优化治理模式,以实现乡村振兴的目标。
