这一栏原来叫「作品」，比它需要的含糊。这里放的都是真的做出来的东西——一个参赛项目、一款软件、一个网站——每一条都按案例来写：问题是什么、做过哪些决定、哪一部分没成。截图是一个项目里最没意思的东西。
This section used to be called Work, which was vaguer than it needed to be. Everything here is a thing that got made — a competition entry, a piece of software, a site — and each one is written up as a case study: the problem, the decisions, and the parts that did not work. Screenshots are the least interesting thing a project has to offer.
把一次真实试验从田间记录一路带到站得住的结论的育种工作台——采、选、洗、算、用五个环节，一条证据链，版本从 V1.0 迭代到了 V13.0。
A breeding workbench that carries a real experiment from field record to defensible conclusion — five stages, one evidence chain, and a version history that now runs from V1.0 to V13.0.
2026 年 6 月下旬起在中国农业大学理学院投入使用的校园智能体：课表、作业、通知、校园事务收进同一个对话框，每个回答都能点回出处。
A campus agent in production at CAU's College of Sciences since June 2026: one conversation box for timetables, deadlines, notices and campus business, with every answer traceable to its source document.
从田间视频里逐株数清气生根的层数。真实遮挡下，单帧检测的准确率只有 36.6–45.1%；本文的遮挡感知多帧融合把株级准确率提到 88.9%。
Counting aerial root tiers per plant from field video. Single-frame detection sits at 36.6–45.1% accuracy under real occlusion; the occlusion-aware multi-frame fusion described here takes plant-level accuracy to 88.9%.
一项已授权（不是受理中）的发明专利：从时序图像高通量测量根系动态生长——时序差分、骨架提取、最短路径定长，最终长成生长曲线。
An invention patent — granted, not pending — for a high-throughput method that measures root length over time from image sequences: temporal differencing, skeleton extraction and shortest-path rooting, assembled into growth curves.
把常用的建模与可视化分析收进一个平台的登记软件（软著 2025SR1800232），是育种家平台三项软著组件之一。
A registered platform (软件著作权 2025SR1800232) that wraps standard modelling and visual analysis into one place — one of the three copyrighted components underneath the breeding platform.
能在 GWAS 量级的基因型矩阵上活着跑完的主成分分析：分块读取、CPU/GPU 双模式、三种主成分数确定方式，计算过程全程可视。
Principal component analysis that survives GWAS-scale genotype matrices: block-wise reading, CPU or GPU execution, three ways to choose the number of components, and a visual trace of the computation while it runs.
GWAS 里不起眼的那一半工作的登记软件（软著 2024SR1711525）：hmp 转纯数阵、数字矩阵插值、正定分块协方差矩阵、定比随机分组。
A registered utility (软件著作权 2024SR1711525) for the unglamorous half of GWAS: HMP-to-matrix conversion, imputation, positive-definite block covariance matrices, and proportional random grouping.
预测某栋建筑、某个点日照时长的桌面软件（软著 2025SR1116569）：用天球几何加上真实遮挡物的形状算阳光，单日与全年两种可视化模式。
A desktop tool (软件著作权 2025SR1116569) that predicts sunshine duration for a building or a point, from celestial-sphere geometry and the actual shapes that block the sky — with single-day and whole-year visual modes.
对同质与异质集成方法在预测与特征选择上的系统比较，投至 ACML 2026、在审中——rebuttal 已交，审稿人的问题已逐条回应。
A systematic comparison of ensemble methods for prediction and feature selection, under review at ACML 2026 — with the rebuttal written and the reviewers' questions answered.

Starting from the graph built on vanishing elements, this project characterises some sporadic simple groups and Chevalley groups — work that produced a joint first-author paper now under review.

This website. Built as a long-lived archive rather than a portfolio, and documented so that the next version is easier to write than this one was.
