1. An Overview of École Polytechnique | 学院概览
École Polytechnique is located in the Paris-Saclay area of France and has been one of the world's leading schools of science and engineering since its foundation in 1794. As the country's oldest and most prestigious institution of its kind, it has produced countless scientists, engineers and entrepreneurs, and is widely recognised as a temple for training elites in science and engineering.
巴黎综合理工学院坐落于法国巴黎-萨克雷地区，自1794年建校以来，始终是全球最顶尖的科学与工程学院之一。作为法国历史最悠久且声誉最卓著的高等学府，它孕育了无数科学家、工程师和企业家，被公认为培养科学及工程领域精英的殿堂。
Two features define the school. First, it is a grande école rather than a large comprehensive university, which means deliberately small cohorts and highly selective entrance. Second, it retains a military statute: students are officer cadets, wear uniform on ceremonial occasions, and take part in national ceremonies such as the 14 July parade in Paris.
这所学院有两个鲜明特征。第一，它是"大学校"（grande école）而非大型综合性大学，这意味着招生规模刻意保持精简、入学竞争极为激烈。第二，它至今保留军事建制：学生具有军官学员身份，在典礼场合穿着制服，并参加诸如巴黎7月14日国庆阅兵等国家仪式。
Its motto, "Pour la Patrie, les Sciences et la Gloire" - For the Fatherland, Science and Glory - captures the double identity that still shapes daily life on campus: a research-driven scientific school that also regards service to the nation as part of its mission.
其校训 "Pour la Patrie, les Sciences et la Gloire"（为祖国、科学与荣誉）概括了至今仍塑造着校园日常的双重身份：它既是一所以研究为驱动的科学学府，也把服务国家视为自身使命的一部分。
2. A Short History since 1794 | 1794年以来的历史沿革
The school was founded in 1794, at the height of the French Revolution, as the École centrale des travaux publics. It was created by figures including Gaspard Monge, Lazare Carnot and Jacques-Élie Lamblardie to supply the young Republic with engineers, surveyors and technical officers. It was renamed École Polytechnique in 1795.
学院创立于1794年法国大革命高潮时期，最初名为"公共工程中央学校"（École centrale des travaux publics）。它由加斯帕尔·蒙日、拉扎尔·卡诺、雅克-埃利·朗布拉尔迪等人创办，目的是为年轻的共和国输送工程师、测绘人员与技术军官。1795年，学校正式更名为"巴黎综合理工学院"。
Under Napoleon, the school acquired its military status and moved into Paris, on the Montagne Sainte-Geneviève, where it trained generations of French scientific and administrative elites. In 1976 it relocated to its present purpose-built campus at Palaiseau, about 20 kilometres south of central Paris.
在拿破仑时期，学校获得军事建制并迁入巴黎圣热讷维耶夫山地区，此后为法国培养了一代又一代科学与行政精英。1976年，学校迁至现址——位于巴黎市中心以南约20公里的帕莱索（Palaiseau）专门建造的校园。
In 2019 the school became a founding member of the Institut Polytechnique de Paris (IP Paris), a cluster that also includes ENSTA Paris, ENSAE Paris, Télécom Paris and Télécom SudParis. This alliance strengthened its research base and its international visibility without changing its historic identity.
2019年，学校成为巴黎综合理工学院联盟（Institut Polytechnique de Paris，简称 IP Paris）的创始成员，该联盟还包括巴黎高等先进技术学校（ENSTA Paris）、国立统计与经济管理学校（ENSAE Paris）、巴黎高等电信学校（Télécom Paris）与南巴黎电信学校（Télécom SudParis）。这一联合强化了它的科研基础与国际能见度，同时并未改变其历史身份。
3. Location and Campus: Paris-Saclay | 地理位置与校园环境
The campus sits on the Saclay plateau in the Île-de-France region, within the wider Paris-Saclay technology and research cluster - an area often described as France's answer to Silicon Valley plus a national laboratory. The site covers roughly 180 hectares and combines teaching buildings, research laboratories, student residences and extensive sports facilities.
校园位于法兰西岛大区的萨克雷高地，处于更广阔的巴黎-萨克雷科技与研究集群之中——这一区域常被形容为"法国的硅谷加国家实验室"。校区占地约180公顷，集教学楼、科研实验室、学生宿舍与大量体育设施于一体。
The location matters academically. Nearby institutions include CNRS laboratories, CEA research centres, the Université Paris-Saclay and several engineering schools, so students can attend joint seminars, use shared equipment and meet researchers from outside their own department.
地理位置在学术上十分重要。周边聚集了法国国家科研中心（CNRS）实验室、原子能与替代能源委员会（CEA）研究中心、巴黎-萨克雷大学以及多所工程师学校，学生因此可以参加联合研讨会、使用共享设备，并结识本院系之外的研究人员。
In practice the campus is self-contained: the "casert" refectory, the library, the sports halls and the student clubs are all on site, while the RER B line links Palaiseau to central Paris in around 40 minutes. Many students live on campus during the first two years of the engineering programme.
实际上，校园自成一体：食堂"casert"、图书馆、体育馆与学生社团都在校内，而 RER B 线可在约40分钟内把帕莱索与巴黎市中心连接起来。许多学生在工程师项目的前两年选择住校。
4. Academic Structure: Bachelor and Master Programs | 学术体系：本科与硕士课程
The school's teaching is organised around three main layers: the Bachelor of Science, the Ingénieur Polytechnicien programme, and postgraduate study at master's and doctoral level. Each layer has its own admission route, its own rhythm and its own assessment style.
学院的教学围绕三个主要层次组织：理学士本科项目、工程师培养项目（Ingénieur Polytechnicien），以及硕士与博士层次的研究生教育。每个层次都有各自的招生通道、教学节奏与考核方式。
The Bachelor of Science is a three-year, honours-level degree taught in English, built around a double major. Students typically combine a core science subject such as mathematics, physics, chemistry, computer science or biology with a second subject that may include economics or another science discipline. Cohorts are small and classes are interactive.
理学士是一个为期三年、以英语授课的荣誉学位项目，采用"双主修"结构。学生通常把一个核心理科方向——如数学、物理、化学、计算机科学或生物——与第二个方向组合，第二个方向可以是经济学，也可以是另一门理科。班级规模很小，课堂互动性强。
Master's programmes generally run for two years and are delivered within the IP Paris framework, mostly in English. They are research-oriented and often act as a springboard into doctoral study. The doctoral school then supervises PhD candidates in mathematics, physics, computer science, mechanics, biology, chemistry and economics.
硕士项目通常为期两年，在 IP Paris 框架内开设，多数以英语授课。它们以研究为导向，常常成为通往博士阶段的跳板。博士学院则在数学、物理、计算机科学、力学、生物、化学与经济学等方向指导博士生。
The Ingénieur Polytechnicien programme is the historic core of the school and lasts four years, combining a broad multidisciplinary foundation with a final specialisation. It is described in more detail in section 6.
工程师培养项目是学院历史最悠久的核心项目，学制四年，把宽广的跨学科基础与最后的专业方向结合起来。第6节将对此作更详细的介绍。
5. Subject Coverage: From Mathematics to Economics | 学科覆盖
The school's teaching and research span an unusually wide range of disciplines for an institution of its size. Physics, mathematics, computer science, chemistry, biology, economics and engineering are all represented, and students are encouraged to cross boundaries rather than stay in one silo.
就学校规模而言，其教学与研究覆盖的学科范围异常宽广。物理、数学、计算机科学、化学、生物、经济学与工程学一应俱全，学校也鼓励学生跨越学科边界，而不是固守单一领域。
The table below summarises the main fields and what students typically encounter in each of them.
下表概括了主要学科领域以及学生在各领域中通常接触到的内容。
| Subject 学科 | Typical content 典型内容 |
| Mathematics 数学 | Analysis, algebra, probability, numerical methods, applied modelling 分析、代数、概率、数值方法、应用建模 |
| Physics 物理 | Quantum mechanics, statistical physics, optics, laser and plasma physics 量子力学、统计物理、光学、激光与等离子体物理 |
| Computer Science 计算机科学 | Algorithms, machine learning, data science, networks, software projects 算法、机器学习、数据科学、网络、软件项目 |
| Chemistry 化学 | Molecular chemistry, materials, interfaces, physical chemistry 分子化学、材料、界面、物理化学 |
| Biology 生物 | Quantitative biology, bioinformatics, biophysics 定量生物学、生物信息学、生物物理 |
| Economics 经济学 | Microeconomics, econometrics, market design, public policy 微观经济学、计量经济学、市场设计、公共政策 |
| Engineering 工程学 | Mechanics, materials, energy, systems and design projects 力学、材料、能源、系统与设计项目 |
Humanities and social sciences are not optional extras here. Every engineering student follows courses in economics, humanities, languages and communication, on the argument that technical leaders must be able to explain their work to non-specialists.
人文与社会科学在这里并非可有可无的点缀。每位工程师学生都要修读经济学、人文科学、语言与沟通类课程，其理由是：技术领导者必须有能力向非专业人士解释自己的工作。
6. The Ingénieur Polytechnicien Programme | 工程师培养项目
The four-year Ingénieur Polytechnicien programme is the school's signature degree. The first two years are deliberately multidisciplinary, covering mathematics, applied mathematics, physics, mechanics, chemistry, biology, computer science, economics and humanities, so that students build a common scientific language before they choose a direction.
四年制工程师培养项目是学院最具标志性的学位。前两年刻意保持跨学科性，涵盖数学、应用数学、物理、力学、化学、生物、计算机科学、经济学与人文科学，让学生在确定方向之前先建立共同的科学语言。
Years three and four are devoted to specialisation, chosen from departments that include mathematics, physics, mechanics, computer science, chemistry and biology, economics, and various engineering fields. Students also complete a collective scientific project, an innovation and design project, and one or more research placements.
第三、第四年进入专业深耕阶段，可从数学、物理、力学、计算机科学、化学与生物、经济学以及多个工程领域等院系中选择方向。学生还需完成一个集体科学项目、一个创新设计项目，以及一次或多次研究实习。
The programme also includes military and physical training, a human-sciences component and, for many students, a period of civic or military service. Because promotions are relatively small, students know their year group well, which builds both loyalty and the famous alumni network.
该项目还包含军事与体能训练、人文科学模块，许多学生还要完成为期一段时间的公民服务或军事服务。由于每个年级规模相对较小，学生彼此熟悉，这既培养了归属感，也造就了著名的校友网络。
The whole structure rests on a simple assumption: a strong mathematical foundation plus real project experience is the most transferable intellectual toolkit a young engineer can own.
整套结构建立在一个朴素的假设之上：扎实的数学基础加上真实的项目经验，是一位年轻工程师所能拥有的最具迁移价值的思维工具。
7. Learning by Doing: Labs, Projects and Internships | 学以致用：实验室、工程实践与实习
The school places heavy emphasis on applying knowledge. Laboratory work, engineering practice and internships are embedded in the curriculum rather than treated as optional extras, and students are expected to spend significant time producing results rather than only consuming lectures.
学院极为强调学以致用。实验室研究、工程实践与实习被嵌入课程体系之中，而非作为可选附加项；学生被期待投入大量时间产出结果，而不只是接受讲授。
Internships are a structural part of every track. Engineering students complete a research internship in a laboratory and an applied internship in industry, and many also spend a longer placement abroad. Master's students normally undertake a research thesis placement of several months.
实习是每条培养路径的结构性组成部分。工程师学生要完成一次实验室研究实习和一次产业应用实习，许多人还会进行更长时间的海外实习。硕士生通常要完成数月的研究论文实习。
Entrepreneurship is supported too: the campus hosts an incubator and an innovation centre, and student teams regularly turn course projects into prototypes and start-ups. For students who want to test an idea before committing to a career, this environment shortens the distance between theory and market.
创业同样受到支持：校园内设有
