1. Saussure’s Sign Theorem: Signifier + Signified | 索绪尔符号定理：能指 + 所指

Sign = Signifier (Sr) + Signified (Sd)

Swiss linguist Ferdinand de Saussure argued that a sign is the basic unit of meaning, made up of two inseparable sides: the signifier (the physical form, such as a written word, spoken sound or image) and the signified (the mental concept it triggers). There is no natural link between them; the connection rests on social convention and shared codes.

瑞士语言学家费迪南·德·索绪尔提出，符号是构成意义的基本单位，由不可分割的两面组成：能指（物理形式，如书面单词、语音或图像）与所指（它所唤起的心理概念）。二者之间没有天然联系，其结合依赖于社会规约和共享符码。

Saussure emphasised that meaning arises from difference within the system. For example, ‘cat’ gains its meaning not because it resembles a cat but because it is not ‘bat’ or ‘cap’. This relational principle underpins all semiotic analysis.

索绪尔强调，意义源自系统内部的差异。例如，’cat’获得意义不是因为它像猫，而是因为它不是’bat’或’cap’。这种关系性原则是所有符号学分析的根基。

2. Barthes’ Myth Theorem: Second-order Signification | 巴特神话定理：第二层意指

Myth ≔ (Denotative Sign₁ as Sr₂) + Connotation₂

Roland Barthes extended semiotics by introducing the idea of myth as a second-order semiological system. The first-order sign (signifier + signified, or denotation) becomes the signifier at the level of myth, where it attaches a new signified (connotation) that serves dominant ideology. In this way, apparently natural images are shown to carry ideological baggage.

罗兰·巴特将符号学延伸，提出神话是第二级符号系统。第一级符号（能指+所指，即外延意义）在神话层面变成新的能指，并被赋予一个新的所指（内涵），服务于主流意识形态。这样一来，看似自然的图像便被揭示出携带着意识形态包袱。

For instance, a magazine cover showing a black soldier saluting the French flag first denotes a soldier saluting. At the mythic level, however, the same image connotes French imperial unity and suggests that all citizens, regardless of colour, faithfully serve the nation, thereby naturalising colonialism.

例如，一张黑人战士向法国国旗敬礼的杂志封面，首先外延指一名士兵在敬礼。但在神话层面，同一图像内涵着法兰西帝国的统一性，暗示无论肤色，所有公民都忠诚地服务于国家，从而将殖民主义自然化。

3. Peirce’s Triadic Sign Theorem: Icon, Index, Symbol | 皮尔斯符号三分定理：像似符、指示符、象征符

Sign = Representamen + Object → Interpretant;
Category: Icon (similarity) | Index (physical link) | Symbol (code)

American philosopher C. S. Peirce proposed a triadic model where a sign (representamen) stands for its object in such a way as to produce an interpretant (the mental effect). Depending on the relationship to the object, signs fall into three types: an icon resembles the object (e.g. a photograph); an index has a direct causal or physical connection (e.g. smoke indicates fire); a symbol is linked by arbitrary convention (e.g. a red rose symbolises love).

美国哲学家皮尔斯提出三元模式：符号（再现体）代表某一对象，并由此产生解释项（心灵效果）。根据与对象的关系，符号分为三类：像似符与对象相似（如照片）；指示符与对象有直接的因果或物理联系（如烟指示火）；象征符由任意约定联系（如红玫瑰象征爱情）。

In media texts, these types often combine. A documentary photograph is iconic (it looks like the subject) and indexical (light rays physically caused the image). Logos are largely symbolic but may incorporate iconic elements. Recognising these modes strengthens your ability to decode visual meaning.

在媒体文本中，这些类型往往混合出现。纪录片照片是像似符（看起来像被摄体）也是指示符（光线物理上导致了影像）。标识大多属于象征符，但可能含有像似成分。识别这些模式能增强你解码视觉意义的能力。

4. Todorov’s Narrative Equilibrium Formula | 托多罗夫叙事均衡公式

Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium

Tzvetan Todorov proposed that most narratives follow a five-stage structure. They begin with a stable state (equilibrium), which is then broken by an event (disruption). Characters subsequently recognise the disruption and undertake a quest to restore order. The story ends with a new equilibrium, often altered by the events. This formula is ubiquitous in Hollywood films, fairy tales and television drama.

茨维坦·托多罗夫提出，多数叙事遵循五阶段结构：开始于稳定状态（均衡），随后被某个事件打破（破坏）；人物随后意识到破坏，并尝试恢复秩序；故事以新的均衡结束，该均衡通常因事件而改变。此公式在好莱坞电影、童话和电视剧中无处不在。

For instance, in a superhero movie, the city is safe (equilibrium) until a villain attacks (disruption). The hero realises the threat, seeks allies and a weapon (repair attempt), and finally defeats the villain, establishing a safer, albeit changed, city (new equilibrium).

例如，在一部超级英雄电影中，城市安全（均衡）直到反派进攻（破坏）。英雄意识到威胁，寻找盟友和武器（修复尝试），最终击败反派，建立了一个更安全但有所改变的城市（新均衡）。

5. Propp’s Character Function Theorem | 普罗普角色功能定理

Narrative = f( Hero, Villain, Donor, Helper, Princess, Dispatcher, False Hero )

Vladimir Propp analysed Russian folk tales and concluded that, despite surface variety, they operate with a fixed set of seven character ‘spheres of action’ (dramatis personae). The specific characters may change, but these functions recur. The theorem is a powerful tool for dissecting story structures and revealing narrative expectations.

弗拉基米尔·普罗普在分析俄罗斯民间故事后得出结论：尽管表面多样，故事总是围绕固定七种角色‘行动圈’运行。具体角色可能改变，但这些功能一再出现。此定理是剖析故事结构、揭示叙事预期的有力工具。

Hero	Seeks something, reacts to donor, weds princess	主人公：追寻目标，回应赠与者，迎娶公主
Villain	Opposes the hero	反派：对抗主人公
Donor	Provides a magical agent or object	赠与者：提供法宝或关键物件
Helper	Assists the hero, often sidekick	帮手：协助主人公，常为搭档
Princess	The sought-for reward, often a person or object	公主（被寻求者）：奖赏，常为人或物
Dispatcher	Sends the hero on the quest	派遣者：派主人公上征程
False Hero	Claims to be the hero, often exposed	伪主人公：冒领功劳，常被拆穿

6. Levi-Strauss’ Binary Opposition Theorem | 列维-斯特劳斯二元对立定理

Meaning = Σ (Opposition A vs Opposition B)

Claude Levi-Strauss argued that human beings make sense of the world through binary oppositions, such as good/evil, man/woman, civilised/savage. Narrative meaning is constructed from the conflict between these pairs. Media texts constantly draw on such opposites to structure plots and character types, and to reinforce cultural values.

克劳德·列维-斯特劳斯认为，人类通过二元对立来理解世界，如善与恶、男与女、文明与野蛮。叙事意义恰是通过这些成对概念的冲突建构起来的。媒体文本不断借助此类对立来编织情节、塑造角色类型，并巩固文化价值观。

For example, a crime drama might set the honest, world-weary detective (good/order) against a corrupt corporate criminal (evil/chaos). The resolution usually favours one pole, thereby endorsing a particular ideology. Deconstructing these pairs exposes the text’s underlying messages.

例如，一部犯罪剧可能将正直但疲惫的侦探（善/秩序）与腐败的企业罪犯（恶/混乱）对立起来。结局通常偏向一方，从而认可特定意识形态。解构这些对立便能揭示文本潜藏的讯息。

7. Neale’s Genre Theorem: Repetition and Variation | 尼尔类型定理：重复与差异

Genre = Repetition + Variation (difference)

Steve Neale argues that genres are not fixed formulas but dynamic systems governed by two forces: repetition of familiar elements (icons, settings, styles) that satisfy audience expectations, and variation (‘difference’) that introduces novelty to prevent boredom and allow the genre to evolve. Box office success depends on balancing the familiar and the new.

史蒂夫·尼尔主张，类型并非一成不变的公式，而是受两种力量支配的动态系统：重复观众熟悉的元素（标志、场景、风格）以满足预期；以及差异（新变体）引入新奇感，防止厌倦并推动类型演变。票房成功取决于熟悉与新颖之间的平衡。

Consider the slasher horror genre. It repeats the ‘final girl’ trope, isolated settings and masked killer, but films like Scream added self-aware meta-commentary, thus varying the code. This theorem helps explain why genres persist yet constantly shift.

以恐怖砍杀类型为例，它不断重复‘最后幸存女孩’、孤立的场景和面具杀手等套路，但如《惊声尖叫》加入了自反式的元评论，从而改变了符码。此定理有助于解释为何类型既长久延续又不断变迁。

8. Hall’s Encoding/Decoding Theorem | 霍尔编码与解码定理

Meaning = Encoding (Producer) → Text → Decoding (Audience):
Dominant, Negotiated, Oppositional

Stuart Hall challenged the linear transmission model by highlighting that audiences do not passively absorb messages. Producers encode a preferred meaning in the text, but audiences decode it based on their own cultural frameworks. Hall identified three decoding positions: dominant-hegemonic (accepting the preferred meaning), negotiated (partly accepting and partly modifying it), and oppositional (completely rejecting the preferred reading in favour of an alternative frame).

斯图亚特·霍尔挑战了线性传输模型，强调受众并非被动吸收讯息。制作者将优先意义编码入文本，但受众依据自身的文化框架解码。霍尔提出三种解码立场：主导-霸权式（全盘接受优先意义）、协商式（部分接受、部分修改）、以及对抗式（完全拒绝优先阅读，代之以替代框架）。

For instance, a news report about a protest might encode the protesters as disruptive. A dominant decoding agrees with this; a negotiated decoding might say the protest is disruptive but also highlights legitimate grievances; an oppositional decoding might celebrate the protesters as heroes fighting injustice. This theorem is fundamental for audience analysis.

例如，一则关于抗议的新闻报道可能将抗议者编码为扰乱秩序者。主导解码同意此说法；协商解码可能认为抗议确有扰乱，但也指出其合理诉求；对抗解码则可能赞美抗议者是为正义而战的英雄。此定理是受众分析的基石。

9. Uses and Gratifications Formula | 使用与满足公式

Gratifications = f(Individual Needs, Media Selection)

Blumler and Katz’s uses and gratifications model shifts the question from ‘what do media do to people?’ to ‘what do people do with media?’. Audiences actively choose media to satisfy specific needs: surveillance (information gathering), personal identity (reinforcing values), personal relationships (social interaction or parasocial companionship) and diversion (escapism). The formula encourages you to treat audiences as active, goal-directed users.

布鲁默与卡茨的使用与满足模型将问题从‘媒体对人做了什么’转向‘人用媒体做了什么’。受众主动选择媒体来满足特定需求：信息监测（获取资讯）、个人身份（强化价值观）、人际关系（社会互动或准社交陪伴）以及消遣（逃避现实）。这一公式鼓励你将受众视为主动
