1. Duverger’s Law | 迪韦尔热定律

Duverger’s Law states that single-member constituency electoral systems with a simple plurality rule (first-past-the-post) tend to favour a two-party system. In such a system, voters realise that casting a ballot for a minor party is often wasted, so they strategically choose the less objectionable of the two leading candidates. Over time, this psychological effect squeezes out third parties and produces stable two-party competition.

迪韦尔热定律指出，采用单一选区相对多数制（简单多数制）的选举制度倾向于形成两党制。在这种制度下，选民意识到投票给小党往往是浪费选票，于是策略性地选择两个主要候选人中不那么讨厌的一个。久而久之，这种心理效应会挤压第三党派的生存空间，形成稳定的两党竞争格局。

2. Iron Law of Oligarchy | 寡头统治铁律

The Iron Law of Oligarchy, formulated by Robert Michels, suggests that any large organisation, no matter how democratic its initial aims, will inevitably become controlled by a small elite. Leaders gain specialised knowledge and control over communication channels, creating a gap between the rank-and-file members and the leadership. This tendency can be observed in political parties, trade unions and even protest movements.

由罗伯特·米歇尔斯提出的寡头统治铁律认为，任何大型组织，不论其最初的宗旨多么民主，最终都将不可避免地由少数精英控制。领导者获得专门知识并掌控沟通渠道，造成普通成员与领导层之间的鸿沟。这一趋势可见于政党、工会乃至抗议运动之中。

3. Separation of Powers | 权力分立

The doctrine of separation of powers divides government into three distinct branches: the legislature (Parliament), which makes laws; the executive (Government), which implements laws; and the judiciary (courts), which interprets and enforces laws. In the UK, this separation is partial because ministers sit in Parliament, but reforms such as the Constitutional Reform Act 2005 have strengthened judicial independence by creating the Supreme Court.

权力分立原则将政府划分为三个独立的分支：立法机关（议会）负责制定法律；行政机关（政府）负责实施法律；司法机关（法院）负责解释和执行法律。在英国，这种分立是部分的，因为大臣同时是议会议员，但2005年《宪制改革法》等改革通过设立最高法院加强了司法独立。

4. Checks and Balances | 制衡机制

Checks and balances ensure that no single branch of government becomes too powerful. Each branch has powers to limit or check the actions of the other two. For example, Parliament can scrutinise the executive through Prime Minister’s Questions and select committees, while the judiciary can review whether public bodies have acted lawfully through judicial review. An independent media also acts as a vital external check.

制衡机制确保没有哪一个政府部门变得过于强大。每个分支都拥有限制或约束其他两个分支行动的权力。例如，议会可通过首相质询和特别委员会来审查行政机关，而司法机关可通过司法复核审查公共机构的行为是否合法。独立的媒体也发挥着至关重要的外部制衡作用。

5. Rule of Law | 法治原则

The rule of law is the principle that all individuals and organisations, including the government itself, are subject to and accountable under the law. Laws must be clear, publicly known, applied equally and protect fundamental rights. In the UK, the rule of law is upheld through an independent judiciary, and no one can be punished except through the ordinary legal process.

法治原则是指所有个人和组织，包括政府本身，都受法律约束并依法承担责任。法律必须明确、向公众公开、平等适用并保护基本权利。在英国，法治通过独立的司法机关得以维护，任何人不得在普通法律程序之外受到惩罚。

6. First-Past-the-Post (FPTP) | 简单多数制

The first-past-the-post electoral system is used for UK general elections. Voters in each constituency choose one candidate, and the candidate with the most votes wins, even if they do not secure an absolute majority. FPTP tends to produce strong, single-party governments but can result in highly disproportionate outcomes, where a party’s share of seats does not match its share of the national vote.

简单多数制是英国大选使用的选举制度。每个选区的选民选择一名候选人，得票最多的候选人获胜，哪怕其并未获得绝对多数票。简单多数制通常能产生强大的单一政党政府，但也可能造成非常不具代表性的结果，即政党获得的议席比例与其全国得票率不相匹配。

7. Proportional Representation (PR) | 比例代表制

Proportional representation electoral systems allocate seats in rough proportion to the votes each party receives. Forms of PR are used for elections to the Scottish Parliament, the Welsh Senedd and the Northern Ireland Assembly. PR tends to result in coalition or minority governments, reflecting a wider range of views but sometimes making decision-making slower and less stable.

比例代表制选举制度按照各政党所获选票的大致比例来分配议席。其变体形式被用于苏格兰议会、威尔士议会和北爱尔兰议会的选举。比例代表制通常导致联合政府或少数派政府，反映更广泛的观点，但有时会使决策过程变慢且不够稳定。

8. Political Spectrum (Left-Right) | 政治光谱（左-右）

The left-right political spectrum is a model for classifying political positions. Left-wing viewpoints generally support greater economic equality, state intervention in the economy, and progressive social policies. Right-wing positions typically emphasise free markets, individual responsibility, lower taxation, and traditional social values. In the UK, the Labour Party is positioned to the centre-left, while the Conservative Party is centre-right.

左-右政治光谱是对政治立场进行分类的模型。左翼观点普遍支持更大的经济平等、国家干预经济和进步的社会政策。右翼立场通常强调自由市场、个人责任、较低税收和传统社会价值观。在英国，工党位于中左位置，保守党位于中右位置。

9. Magna Carta (1215) | 《大宪章》(1215年)

Magna Carta is a foundational document in the development of constitutional government. It established the principle that the monarch is not above the law and guaranteed certain rights, such as the right to a fair trial. Clauses like ‘no free man shall be seized or imprisoned … except by the lawful judgment of his equals’ are seen as precursors to modern concepts of due process and the rule of law.

《大宪章》是宪制政府发展过程中的一份奠基性文件。它确立了君主也不能凌驾于法律之上的原则，并保障了某些权利，如接受公正审判的权利。’任何自由人，非经其同等地位人士的合法审判……不得被逮捕或监禁’等条款被视为现代正当程序与法治概念的先驱。

10. Core Principles of Democracy | 民主的核心原则

A functioning democracy rests on several bedrock principles. Representation ensures that elected officials speak for their constituents. Accountability means those in power must justify their actions and can be removed through elections. Participation requires that citizens are free to vote, join parties and stand for office. Added to these are free and fair elections, civil liberties, and the protection of minority rights. In the UK, these principles are realised through regular general elections, a free press, and institutions like the Equality and Human Rights Commission.

一个正常运作的民主体制建立在若干根基性原则之上。代表制确保民选官员为其选民发声。问责制意味着掌权者必须为其行为作出解释，并可通过选举予以罢免。参与性要求公民能够自由投票、加入政党及参选公职。此外还要有自由公正的选举、公民自由以及对少数群体权利的保护。在英国，这些原则通过定期大选、新闻自由及平等与人权委员会等机构得以实现。
