你好！我是 PZX Hello! I Am PZX
我在做什么 What I Am Doing
专业上，我主要关注电子科学与技术、嵌入式系统、通信原理、信号处理和基础工程实现。相比单纯罗列课程，我更关心一件事：代码、硬件、信号和系统如何在真实问题里连起来。
Academically and professionally, my focus lies in electronic science and technology, embedded systems, principles of communications, signal processing, and foundational engineering implementation. Rather than simply reciting coursework, I care much more about one essential question: how code, hardware, signals, and systems connect to solve real-world problems.
个人兴趣上，我长期维护这个网站，也持续写作、整理照片、记录生活和搭建自己的内容索引。这里既有偏技术和课程的记录，也有关于阅读、影视、城市、校园、关系和自我观察的文章。
In terms of personal interests, I have maintained this website over the long term, continuously writing, archiving photographs, documenting daily life, and building my own content index. Here you will find technical notes and course reflections alongside essays on reading, film, cities, campus life, human relationships, and self-observation.
这个网站是什么 What This Website Is
这个网站是我的个人档案馆。它不只展示某一种身份，而是把文章、照片、年度文集、内容星图和生活记录放在同一个空间里。
This website is my personal archive. Rather than projecting a single identity, it brings together essays, photographs, annual anthologies, a semantic content map, and life records into one unified space.
你可以把它理解成一个持续更新的自我索引：有些内容偏公开表达，有些内容偏私人整理；有些适合快速浏览，有些适合沿着时间线慢慢读。
You can think of it as a continually updated self-index: some pieces lean toward public expression, while others are personal notes; some are suited for a quick glance, and others are meant to be read slowly along the timeline.

Looking ahead, I hope to achieve even greater growth and breakthroughs!
本科期间学习最感兴趣/成绩最好的课程及原因：嵌入式系统设计 这门课让我第一次真正理解了代码是如何驱动硬件工作的。当我自己编写的驱动程序成功点亮LED矩阵或读取到传感器数据时，那种“打通底层逻辑”的成就感让我非常着迷。它将我之前学的模电、数电知识与C语言编程串联了起来，让我建立起了完整的计算机系统观，不再是盲目地敲代码，而是理解背后的内存管理和时序控制。
Most engaging and highest-performing course during undergraduate studies: Embedded System Design. This course gave me my first genuine understanding of how software drivers bring hardware to life. When the device drivers I wrote successfully illuminated an LED matrix or fetched real-time sensor data, the thrill of unlocking the underlying hardware logic captivated me completely. It seamlessly bridged my prior background in analog and digital electronics with C programming, helping me build a coherent, full-stack view of computer systems—moving beyond blindly typing out code to genuinely mastering memory management, register configuration, and timing control.
本科期间最难忘的事情：参加美国数学建模大赛时，比赛的第三天深夜，我们的核心算法模型在处理大规模数据时出现了严重的收敛性问题，而距离提交截止仅剩不到24小时。 当时全队都已极度疲惫，但我们没有互相指责，而是决定通宵作战。作为负责编程的队员，我对着屏幕逐行检查参数、调试代码；队友则在一旁帮我查阅最新的文献修正公式。当凌晨4点看到模型跑出的结果曲线终于平滑拟合时，那种疲惫一扫而空，虽然最终结果一般但着实是很难忘的记忆。
Most memorable experience during undergraduate studies: Competing in the MCM/ICM (MCM Mathematical Contest in Modeling). Late into the night of the third day, our core algorithmic model suffered severe convergence issues when processing large-scale datasets, with less than twenty-four hours remaining until the submission deadline. Everyone on the team was exhausted, but instead of blaming one another, we chose to fight through the night together. As the member responsible for programming, I went through the code and parameters line by line on screen; my teammates sat beside me searching literature and rectifying mathematical formulas. When the output curves finally converged smoothly at 4:00 AM, our exhaustion vanished in an instant. Even though our final ranking was modest, that all-night push remains an unforgettable memory.
未来参加工作，我最担心的是：自己的代码和设计还停留在“实验室/学术”标准，未能快速达到企业的“量产/工程化”标准。在学校做项目，往往只要功能实现了就行，很少考虑代码的鲁棒性、可维护性以及边界条件的测试。但我深知在企业中，产品的稳定性至关重要。 我担心自己初入职场时，会因为缺乏大规模工程经验而写出“虽然能跑但不好维护”的代码。
Primary concern when entering the workforce: That my code and design mindset might remain tethered to “laboratory and academic” benchmarks rather than quickly adapting to industrial “mass production and engineering” standards. In university projects, achieving basic functionality is often considered sufficient, with little emphasis on robustness, maintainability, or rigorous boundary testing. Yet in industry, product reliability and stability are paramount. My greatest concern when stepping into the professional arena was that a lack of large-scale engineering experience might lead to code that “runs, but is difficult to maintain.”
