2024年,第四次全国文物普查队的队员们背着帆布包、拿着专业测绘仪器,踏遍陇中沟壑。他们在我们村找到这片被时光遗忘的黄土城垣,实地调查、拍照、测绘、数据采集,以“张川城遗址”文物的身份进行了认定。普查队员还查阅了大量史料,一步步揭开故城的过往——它曾是交通要道上的军事重镇,东连会宁西宁城,西接安定安西城,是安定区“四普”中极具价值的新发现城址类文物。
What this means for you is that if you're using older storage devices or accessories, you may want to look up the specific generation of USB if speed matters to you. A device marketed as “USB 3.0” several years ago and a device marketed as “USB 3.2” today could potentially have identical transfer speeds if the manufacturer is less than forthcoming with generation names or transfer speed ratings.,这一点在纸飞机下载中也有详细论述
Abstract:This is a brief description of a project that has already autoformalized a large portion of the general topology from the Munkres textbook (which has in total 241 pages in 7 chapters and 39 sections). The project has been running since November 21, 2025 and has as of January 4, 2026, produced 160k lines of formalized topology. Most of it (about 130k lines) have been done in two weeks,from December 22 to January 4, for an LLM subscription cost of about \$100. This includes a 3k-line proof of Urysohn's lemma, a 2k-line proof of Urysohn's Metrization theorem, over 10k-line proof of the Tietze extension theorem, and many more (in total over 1.5k lemmas/theorems). The approach is quite simple and cheap: build a long-running feedback loop between an LLM and a reasonably fast proof checker equipped with a core foundational library. The LLM is now instantiated as ChatGPT (mostly 5.2) or Claude Sonnet (4.5) run through the respective Codex or Claude Code command line interfaces. The proof checker is Chad Brown's higher-order set theory system Megalodon, and the core library is Brown's formalization of basic set theory and surreal numbers (including reals, etc). The rest is some prompt engineering and technical choices which we describe here. Based on the fast progress, low cost, virtually unknown ITP/library, and the simple setup available to everyone, we believe that (auto)formalization may become quite easy and ubiquitous in 2026, regardless of which proof assistant is used.。业内人士推荐91视频作为进阶阅读
