A baby sleeps in all our bones,so scared to be ...

这首由Iron&Wine演唱的《PassingAfternoon》通过四季更迭象征人生的变迁与岁月的流逝。歌词中讲述了从夏日到冬日,主人公面对生活选择与失去的故事,用诗意的语言描绘了生命中的美好瞬间及随之而来的改变。

 

Passing Afternoon

 

     -- Iron & Wine

 

 

There are times that walk from you like some passing afternoon
Summer warmed the open window of her honeymoon
And she chose a yard to burn but the ground remembers her
Wooden spoons, her children stir her Bougainvillea blooms

There are things that drift away like our endless, numbered days
Autumn blew the quilt right off the perfect bed she made
And she's chosen to believe in the hymns her mother sings
Sunday pulls its children from their piles of fallen leaves

There are sailing ships that pass all our bodies in the grass
Springtime calls her children 'till she let's them go at last
And she's chosen where to be, though she's lost her wedding ring
Somewhere near her misplaced jar of Bougainvillea seeds

There are things we can't recall, blind as night that finds us all
Winter tucks her children in, her fragile china dolls
But my hands remember hers, rolling 'round the shaded ferns
Naked arms, her secrets still like songs I'd never learned

There are names across the sea, only now I do believe
Sometimes, with the windows closed, she'll sit and think of me
But she'll mend his tattered clothes and they'll kiss as if they know
A baby sleeps in all our bones, so scared to be alone

 

 

 

内容概要:本文介绍了一个基于MATLAB实现的多目标粒子群优化算法(MOPSO)在无人机三维路径规划中的应用。该代码实现了完整的路径规划流程,包括模拟数据生成、障碍物随机生成、MOPSO优化求解、帕累托前沿分析、最优路径选择、代理模型训练以及丰富的可视化功能。系统支持用户通过GUI界面设置参数,如粒子数量、迭代次数、路径节点数等,并能一键运行完成路径规划与评估。代码采用模块化设计,包含详细的注释,同时提供了简洁版本,便于理解和二次开发。此外,系统还引入了代理模型(surrogate model)进行性能预测,并通过多种图表对结果进行全面评估。 适合人群:具备一定MATLAB编程基础的科研人员、自动化/控制/航空航天等相关专业的研究生或高年级本科生,以及从事无人机路径规划、智能优化算法研究的工程技术人员。 使用场景及目标:①用于教学演示多目标优化算法(如MOPSO)的基本原理与实现方法;②为无人机三维路径规划提供可复现的仿真平台;③支持对不同参数配置下的路径长度、飞行时间、能耗与安全风险之间的权衡进行分析;④可用于进一步扩展研究,如融合动态环境、多无人机协同等场景。 其他说明:该资源包含两份代码(详细注释版与简洁版),运行结果可通过图形界面直观展示,包括Pareto前沿、收敛曲线、风险热图、路径雷达图等,有助于深入理解优化过程与结果特性。建议使用者结合实际需求调整参数,并利用提供的模型导出功能将最优路径应用于真实系统。
