1. Narrative Equilibrium Formula | 叙事平衡公式

Todorov’s theory of narrative can be expressed as a five-stage formula: Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium. Every classic story begins with a stable situation, encounters a problem, realises the disruption, takes action to fix it, and finally achieves a transformed balance.

托多罗夫的叙事理论可表达为五阶段公式：平衡 → 破坏 → 认知 → 修复尝试 → 新平衡。每个经典故事都始于稳定状态，遭遇问题，意识到破坏，采取行动修复，最终达到一种转变后的平衡。

Equilibrium: The normal, calm world of the protagonist.
Disruption: An event that unsettles the balance, often introduced by a villain or accident.
Recognition: The protagonist and others realise the problem exists.
Attempt to Repair: A quest or plan to solve the disruption.
New Equilibrium: A different state of peace, sometimes better, sometimes scarred.

平衡：主角正常、平静的世界。
破坏：打破平衡的事件，常由反派或意外引入。
认知：主角和他人意识到问题存在。
修复尝试：为解决破坏而展开的探索或计划。
新平衡：一种不同的和平状态，有时更好，有时带着伤痕。

Use this formula when analysing films, television dramas, or print fiction. Identify the five stages to show understanding of structure.

分析电影、电视剧或印刷故事时使用此公式。识别五个阶段来展示对结构的理解。

2. Character Roles Theorem | 角色功能定理

Propp’s character theory identifies seven recurring roles (character functions) found across folk tales and modern media. You can think of them as a theorem: Hero + Villain + Donor + Helper + Princess + Dispatcher + False Hero = Dramatis Personae of the Narrative.

普罗普的角色理论识别了民间故事和现代媒体中反复出现的七种角色（角色功能）。你可以把它们看作一个定理：英雄 + 反派 + 赠予者 + 帮手 + 公主 + 派遣者 + 假英雄 = 叙事的人物群像。

Role	Function
Hero	Seeks something, saves the day.
Villain	Opposes the hero, creates disruption.
Donor	Gives the hero a magical object or advice.
Helper	Assists the hero on the journey.
Princess	The reward; often needs rescuing.
Dispatcher	Sends the hero on the quest.
False Hero	Pretends to be good, often exposed.

角色与功能（中文对照）：英雄——寻求某物，拯救大局；反派——对抗英雄，制造破坏；赠予者——赠予英雄法宝或建议；帮手——在旅途中协助英雄；公主——战利品，常需被拯救；派遣者——派英雄踏上征程；假英雄——冒充好人，常被揭穿。

Applying this theorem helps you decode character motivations in everything from superhero movies to advertising narratives.

应用这一定理有助于你解码从超级英雄电影到广告叙事中的角色动机。

3. Semiotic Code Formula | 符号学代码公式

Barthes’ model of signs can be simplified to: Signifier + Signified = Sign. In media texts, we decode meaning in two stages: Denotation (literal, what is seen) followed by Connotation (the associated cultural meaning). Together, they produce Myth — the deeper ideological message.

巴特的符号模型可简化为：能指 + 所指 = 符号。在媒体文本中，我们分两个阶段解码意义：明示义（字面，所见之物），然后是隐含义（关联的文化意义）。二者共同生成神话——更深层的意识形态信息。

Denotation (red rose) + Connotation (love, passion) → Myth (romantic love is natural and ideal)

明示义（红玫瑰） + 隐含义（爱情、激情） → 神话（浪漫爱情是自然且理想的）

Remember the formula: Denotation → Connotation → Myth. Look at any advert, film poster, or news image and ask: what is literally present? What cultural ideas are attached? What wider belief is being reinforced?

记住公式：明示义 → 隐含义 → 神话。面对任一广告、电影海报或新闻图片时自问：字面上呈现了什么？附着了哪些文化观念？何种更广泛的信念在被强化？

4. Genre Conventions Equation | 类型常规等式

Genre can be defined by a simple equation: Iconography + Repertoire of Elements + Audience Expectations = Genre. Iconography includes visual signs (cowboy hats = Western), repertoire covers settings, character types and themes, while expectations are what audiences anticipate based on prior experience.

类型可用一个简单等式定义：图像志 + 元素库 + 受众期望 = 类型。图像志包含视觉符号（牛仔帽 = 西部片），元素库涵盖场景、角色类型和主题，而期望是受众基于先前经验所预测的内容。

Iconography: Props, costumes, colour palettes, lighting styles that signal the genre.
Repertoire: Typical narratives, stock characters, conflicts (e.g., chase scenes in action films).
Expectations: What the audience enjoys and predicts; genre hybridisation can play with these.

图像志：指示类型的道具、服装、色彩板、灯光风格。
元素库：典型叙事、定型角色、冲突（如动作片中的追逐场面）。
期望：受众喜爱并预测的内容；类型杂糅可以玩弄这些期望。

By decoding the genre equation, you can quickly categorise a media text and evaluate how it follows or subverts the established rules.

通过解码类型等式，你能迅速归类媒体文本，并评估它如何遵循或颠覆既定规则。

5. Mise-en-Scène Memory Formula (CAMELS) | 场面调度记忆公式 (CAMELS)

Mise-en-scène refers to everything placed in front of the camera. The acronym CAMELS helps you remember the six key areas: Costume, Acting & body language, Make-up & hair, Lighting & colour, Setting, and Space & composition.

场面调度指放在摄影机前的一切。缩写词 CAMELS 助你记住六大关键领域：服装、表演与肢体语言、化妆与发型、灯光与色彩、场景、以及空间与构图。

C + A + M + L + S + S = meaningful visual world

服装 + 表演 + 化妆 + 灯光 + 场景 + 空间 = 富有意义的视觉世界

For each element, ask: what does it connote? For example, high-key lighting suggests an upbeat atmosphere, while low-key lighting creates mystery. A cluttered setting might represent chaos.

对于每一元素，自问：它暗示了什么？例如，高调布光暗示欢快氛围，而低调布光制造神秘感。杂乱的场景可能代表混乱。

6. Camera Shot & Angle Meaning Theorem | 镜头景别与角度含义定理

Camera choices are not neutral; they encode meaning. The theorem states: Shot Size + Camera Angle + Movement = Audience Perception. Extreme close-ups reveal emotion; long shots establish context. Low angles give power; high angles suggest vulnerability.

摄影选择并非中性；它们编码意义。此定理为：景别 + 拍摄角度 + 运动 = 受众感知。极端特写揭示情感；远景建立背景。仰角赋予权力；俯角暗示脆弱。

Shot/Angle	Typical Connotation
Extreme Close-Up	Intensity, emotion, focus on detail
Low Angle	Dominance, power, threat
High Angle	Vulnerability, smallness, weakness
Dutch Tilt	Unease, disorientation, tension
Wide Shot	Setting, isolation, scale

镜头/角度与典型含义（中文）：极端特写——强烈、情感、细节聚焦；仰角——支配、权力、威胁；俯角——脆弱、渺小、软弱；荷兰角——不安、迷失方向、紧张；广角镜头——环境、孤立、规模。

Use this theorem to analyse any moving image extract, explaining how technical choices guide viewer sympathy and understanding.

使用此定理分析任何动态影像片段，解释技术选择如何引导观众同情心与理解。

7. Editing Pace & Transition Formula | 剪辑节奏与转场公式

Editing constructs time, space, and rhythm. The editing formula can be expressed as: Cut Frequency + Transition Type + Continuity = Experience of Time. Fast cutting (many short shots) builds excitement; slow cutting creates calm or tension. Transitions like dissolves or fades signal time passing or soft endings.

剪辑构建时间、空间和节奏。剪辑公式可表达为：切换频率 + 转场类型 + 连续性 = 时间体验。快速剪辑（多个短镜头）建立兴奋感；慢速剪辑创造平静或紧张。叠加或淡入淡出等转场指示时间流逝或柔和结束。

Straight Cut: Most common, invisible, maintains flow.
Dissolve: One shot blends into another, often suggests memory or time shift.
Fade to Black: Indicates a significant pause, ending, or change of scene.
Jump Cut: Deliberate break in continuity, creates jarring effect or shows character anxiety.

直切：最常见，不可见，保持流畅。
溶解：一个镜头融入另一镜头，常暗示回忆或时间推移。
淡出至黑屏：表明显著停顿、结束或场景转换。
跳切：故意打破连续性，制造突兀效果或表现角色焦虑。

Remember the formula: Editing speed and transitions are narrative tools, not just technical necessities.

记住公式：剪辑速度和转场是叙事工具，而不仅仅是技术必需品。

8. Audience Uses and Gratifications Equation | 受众使用与满足等式

Blumler and Katz’s model can be summed up as: Information + Personal Identity + Social Interaction + Entertainment = Media Choice. Audiences actively select media to fulfil these four needs.

布鲁默与卡茨的模型可总结为：信息 + 个人身份 + 社会互动 + 娱乐 = 媒体选择。受众主动选择媒体以满足这四种需求。

Information: Learning, seeking advice, satisfying curiosity.
Personal Identity: Reinforcing values, finding models of behaviour, self-understanding.
Social Interaction: Basis for conversation, feeling connected, parasocial relationships with characters.
Entertainment: Escape, relaxation, emotional release, enjoyment.

信息：学习、寻求建议、满足好奇心。
个人身份：强化价值观、寻找行为榜样、自我理解。
社会互动：提供谈资、感受联结、与角色的准社会关系。
娱乐：逃离、放松、情感释放、享受。

Apply this equation when explaining why a particular audience may choose a YouTube channel, a magazine, or a film.

解释某一特定受众为何选择某个YouTube频道、杂志或电影时，应用此等式。

9. Representation Construction Formula | 表征建构公式

Stuart Hall’s representation theory holds that media do not reflect reality; they construct it. The formula: Selection + Mediation + Focus = Representation. Producers select what to show, mediate through technical and editorial choices, and focus on particular aspects to create a version of reality that may reinforce stereotypes or challenge them.

斯图尔特·霍尔的表征理论认为媒体并非反映现实，而是建构现实。公式为：选择 + 中介 + 聚焦 = 表征。制作者选择展示什么，通过技术和编辑选择进行中介，聚焦特定方面以创造一种可能强化或挑战刻板印象的现实版本。

Dyer’s typology adds: stereotypes work through selection, emphasis and exclusion. The stereotype formula: Pick one trait → exaggerate it → ignore everything else → naturalise it as ‘the norm’.

戴尔的类型学补充道：刻板印象通过选择、强调和排斥运作。刻板印象公式：选取一个特征 → 夸大它 → 忽略其他一切 → 使其自然化为“常态”。

Analyse a media product by asking: which groups are represented? What choices have been made to construct that image? What has been left out?

分析媒体产品时自问：哪些群体被表征？为构建那个形象做出了什么选择？遗漏了什么？

10. Media Industry Funding Model | 媒体产业筹资模型

The economic basis of media products can be understood through the formula: Funding Source + Institutional Objective + Technology = Media Output. Public service broadcasters (like the BBC) are funded by licence fees and aim to inform, educate, and entertain; commercial broadcasters rely on advertising and target mass audiences. The model helps explain content differences.

媒体产品的经济基础可通过公式理解：资金来源 + 机构目标 + 技术 = 媒体产出。公共服务广播机构（如BBC）由执照费资助，旨在告知、教育、娱乐；商业广播机构依赖广告，瞄准大众受众。该模型有助于解释内容差异。

Institution	Funding	Primary Objective
BBC	Licence fee	Public service
ITV	Advertising	Maximise viewership
Netflix	Subscription	Retain subscribers

机构与筹资（中文）：BBC – 执照费 – 公共服务；ITV – 广告 – 最大化观众数；Netflix – 订阅 – 留住订户。

This formula reminds you to link a text’s content to the economic forces behind its production.

此公式提醒你将文本内容与其制作背后的经济力量相联系。

11. Narrative Codes Theorem | 叙事代码定理

Barthes identified five codes that weave meaning into a text. The theorem: Hermeneutic Code + Proairetic Code + Semantic Code + Symbolic Code + Cultural Code = Rich Narrative. The hermeneutic code involves mysteries and questions; the proairetic code is about actions that build tension; the symbolic code deals with deeper oppositions; the semantic code handles connotation; and the cultural code refers to shared knowledge.

巴特识别了编织文本意义的五种代码。定理为：阐释码 + 行动码 + 语义码 + 象征码 + 文化码 = 丰富的叙事。阐释码涉及悬念与疑问；行动码关乎构建张力的行为；象征码处理深层的二元对立；语义码负责隐含意义；文化码指涉共享的知识。

For example, in a detective show, a closed door (hermeneutic code) raises the question ‘what is behind it?’; a character loading a gun (proairetic code) signals impending action; light vs darkness symbolism (symbolic code) suggests good vs evil.

例如，在侦探剧中，一扇紧闭的门（阐释码）提出“门后是什么？”的疑问；角色装填子弹（行动码）预示即将发生的行动；光明与黑暗的象征（象征码）暗示善与恶。

Use these codes to peel back layers of meaning in any media text, from film to video game.

使用这些代码层层剥开任何媒体文本（从电影到电子游戏）的意义。

12. Intertextuality Link Formula | 互文性链接公式

Intertextuality — the referencing of one text within another — can be expressed as: Text A + Recognisable Reference to Text B = Shared Meaning (for those in the know). This referencing can be homage, parody, or pastiche, and it rewards audience knowledge.

互文性——一个文本引用另一个文本——可表达为：文本A + 对文本B的可识指涉 = 共享意义（针对知晓者）。这种引用可以是致敬、戏仿或混成，并奖赏受众的知识储备。

Homage: Respectful tribute, e.g., a film referencing a classic shot.
Parody: Mocking imitation for comic effect.
Pastiche: A light-hearted imitation that blends styles without ridicule.

致敬：尊重的效敬，如电影引用经典镜头。
戏仿：为喜剧效果而进行的嘲讽性模仿。
混成：不带嘲讽的轻松模仿，糅合各种风格。

Recognising intertextuality allows you to discuss how modern media is built on a web of prior texts and why audiences enjoy spotting these links.

识别互文性让你能够讨论现代媒体如何建立在先前文本之网上面，以及受众为何乐于发现这些联系。
