摘要：针对受船舶运动状态和推力饱和约束影响的动力定位控制问题,本文提出了一种非线性模型预测控制方法。依据多面体描述理论建立了船舶动力定位多面体描述偏差模型,针对上述模型采用线性矩阵不等式设计非线性模型预测控制器中的终端要素,并证明了闭环系统的稳定性。仿真结果表明:设计的控制器能在满足约束条件和受环境干扰条件下快速控制船舶稳定在计划航向和计划船位,验证了控制器的有效性和本质鲁棒性。

摘要：在舞台表演艺术中,服装色彩不仅起到装饰作用,更承载着丰富的文化内涵。色彩作为一种直观的文化符号,能有效传递文化信息,影响观众的情感体验和文化理解。文章具体分析了服装色彩设计在舞台表演中的功能性和象征性,通过具体案例,阐述了色彩在传递文化符号过程中的核心角色以及艺术创作者如何巧妙利用色彩设计增加作品的表现力和文化深度,多维度探讨了色彩与文化符号的相互影响,展示了色彩设计在舞台艺术中的双重身份——既是视觉魅力的塑造者,也是文化传递的桥梁。这对于未来舞台服装色彩设计和文化符号研究及实际应用都有非常重要的价值和启示意义。

摘要：为研究舰船板架在水下爆炸冲击波载荷作用下的变形及破损,结合现有试验数据,采用仿真和数据拟合的方法,展开了均布载荷下板架边界撕裂损伤的相似准数研究。首先,结合理论和数据分析得出,板架边界撕裂时的初始响应速度与破坏模式密切相关,且可清晰描述板架的不同毁伤模式;进一步通过仿真得出断裂应变、板厚、长宽比是影响板架边界撕裂的重要参量;最后,基于量纲理论建立了用于判定板架边界撕裂毁伤的拟合函数,并根据战场舰船损伤实例验证了该函数的有效性。研究结果表明,基于初始响应速度和考虑断裂应变等参量的无量纲数构建板架边界撕裂毁伤判据的方法是可行的,为舰船板架的毁伤相似研究提供了参考。

摘要：遗产廊道是整合跨区域文化遗产保护与利用的新尝试,支持更大空间尺度上文化遗产间的价值认知与活态延续。从文化生态学视角出发探讨徽州文化遗产保护的新途径,以徽州文保单位作为遗产“源”,借助最小阻力模型、重力模型和电路理论等方法生成潜在廊道并分级,结合传统村落点设置廊道“驿站”,构建“源地—廊道—驿站”的多维度、多层次网络系统。基于此提出“一轴、一带、多核、两翼”空间格局下的生态保护与文化共生策略。以期推动徽州文化遗产网络化保护进程,为徽州地区全域旅游规划和文旅深度融合发展提供参考。

摘要：为了在地面获得高信噪比的太阳直射紫外光谱辐照度,选用紫外敏感型线阵CCD探测器,研发了高光谱紫外辐照度仪原理样机。设计了CCD电路系统,讨论了电源电路、驱动电路、模拟前端电路以及CCD驱动时序的工作原理与设计方法,并在实验室利用标准灯光源测试了CCD电路系统的非线性和信噪比。结果表明,在340 nm波段下,CCD探测器接收信号约为饱和信号的80%时,系统信噪比超过400。最终,将测试好的CCD电路系统与光机模块装调并进行了波长定标,光谱范围覆盖280~400 nm,实现了对室内光源的紫外高光谱测量,验证了CCD电路系统设计的合理性和可行性。

摘要：在摸清遗产资源本底、解析遗产价值构成、遵循遗产工作规律的基础上,明确线性文化遗产网络的保护格局,能够为其系统保护与发展提供科学依据。因此,借助历史文献研究、地理空间分析、主成分分析等方法,完成徽杭古道线性文化遗产的遗产源判别认定、特征分析与价值评估。基于分析结果,划定整体区域、古道网络、遗产保护区和遗产资源点4个空间层次的保护范围。同时,提出各层次的保护、活化、利用重点,以期推进徽杭古道沿线遗产的整体性保护。

摘要：赵孟頫被移出“元四家”,通常解释为“子昂亏节”,陷入了“以人品定艺品”的窠臼,若将董其昌在元四家中“去赵孟頫入倪瓒”与其“南北宗论”联系起来看,会得出不一样的结论。结合“南北宗论”对“士夫画”和“行家画”的区分,董其昌“去赵入倪”实则是纯化文人画正脉,扭转“院画”和“士夫画”的衰落局面,通过去除赵孟頫影响的画坛习气,追求倪瓒纯粹文人士夫的“逸品格调”和草草“逸笔”,以达到重塑文人画史,借古以开今的目的。

摘要：As an important foundation for promoting social progress and economic development, natural resources play an important role in the sustainable development of cities. However, the increasing demand of human beings for natural resources has led to various ecological environmental problems, such as excessive population density, serious environmental pollution, the continuous decline of total natural resources and per capita resources, all of which have hindered sustainable development. Therefore, the study of natural resources and sustainable development has become the focus of many current scholars. In this paper, CiteSpace is used as an analysis tool to analyze the literature on natural resources and sustainable development over the past 20 years. First of all, this paper deeply analyzes the research status of this field in terms of academic research trends, authors and research institutions, co-occurrence of keywords, etc., and on this basis, it then deeply analyzes its evolutionary path and research hot spots in the past 20 years through keyword emergence. Finally, according to the visualization of the analysis results, the future development trends of this research field are speculated:(1) Grasp the current research focus;(2) Improve the research accuracy;(3) Enrich the theoretical system of research;and(4) Establish an interdisciplinary research system.

摘要：构建宜居的城市空间是城市建设的重要内容,城市空间的宜居性评价对于城市可持续发展具有重要意义。文章从“生产-生活-生态(三生)”空间(PLES)视角出发,利用空间分析方法对合肥市区城市空间宜居性水平进行测度,以期为未来城市空间宜居性建设工作提供科学的规划参考,促进城市空间要素协调及空间优化。首先,本文从生活舒适、生产便利、生态健康三个方面,构建城市空间宜居性评价模型。其次,运用城市空间宜居性评价模型、全局空间自相关分析方法、耦合协调度模型,分别对合肥市区城市空间的宜居性单因素分异现状、综合宜居程度和“三生”空间耦合程度进行分析。最后,探讨合肥市区城市空间“三生”要素协调性,并提出提升城市空间宜居性的优化策略。结果表明:(1)在“三生”空间单因素宜居性方面,合肥市区各类型空间的宜居性呈现出显著的分异特征,空间上呈现出生活舒适区中心集聚、生产便利区由中心向外围扩散、生态健康区四周分散的特点;(2)合肥市区空间整体宜居性较高,宜居性高值区主要集中在市区中心,低值区域集中在市区周边;(3)合肥市区“三生”空间耦合协调度水平均呈现城市中心高、四周低的特征,且生活-生产耦合协调度最高,说明两者空间布局具有一定的合理性,实现了良性协调。
