本速查手册汇集了 OCR 普通中等教育证书媒体研究考试所需的核心理论公式与定理。每一节将一个关键媒体概念分解为易于记忆的方程式或模型，并附有清晰的中英文定义。用它来复习符号学、叙事、受众、表征、产业和监管等全部内容，均紧扣 OCR 指定作品与评估目标。
1. Semiotics Formula | 符号学公式
Sign = Signifier + Signified
符号 = 能指 + 所指
otation (literal, first-order meaning) + Connotation (cultural, second-order meaning). Myth, for Barthes, is when a connotation becomes so widely accepted that it appears natural.
罗兰·巴特以“外延”与“内涵”扩展了这一模型：符号 → 外延（字面、第一层意义）+ 内涵（文化、第二层意义）。在巴特看来，“神话”就是当某种内涵被广泛接受，以至于显得自然而然。
In OCR set texts, a police badge signifies law and order (denotation) but connotes authority, protection, or corruption depending on the scene.
在 OCR 指定文本中，一枚警徽表示法律与秩序（外延），但根据场景可内涵权威、保护或腐败。
2. Narrative Structure Formula | 叙事结构公式
Todorov' Equilibrium → Disruption → Recognition of disruption → Attempt to repair → New equilibrium
托多罗夫的平衡模型：叙事 = 平衡 → 打破 → 察觉打破 → 尝试修复 → 新平衡
This formula is especially useful when analysing the episode of Cuffs or The Avengers – a crime (disruption) is recognised, investigated (attempt to repair) and a new social order (new equilibrium) is momentarily restored. Unlike Propp, Todorov emphasises the transformation of the storyworld itself rather than just characters.
在分析《Cuffs》或《复仇者》的剧集时，这一公式格外有用——罪行（打破）被察觉，经调查（尝试修复），社会秩序瞬间重建（新平衡）。与普罗普不同，托多罗夫强调的是故事世界本身的变化，而不仅仅是角色。
3. Propp’s Character Functions Formula | 普罗普角色功能公式
Propp' er spheres: Story roles = {Hero, Villain, Donor, Helper, Princess, Dispatcher, False Hero}
普罗普的七种角色范围：故事角色 = {英雄、反派、赠予者、帮手、公主、派遣者、假英雄}
Each character performs a function within the plot’s 31 possible actions. A single character can occupy more than one sphere, for example, the Dispatcher might also act as the Donor. In many OCR set products, such as film posters or TV crime dramas, characters can be mapped onto these archetypes to reveal ideological values.
每个角色在故事的 31 种可能行动中执行一种“功能”。同一个角色可以占据多个范围，比如，派遣者也可能同时扮演赠予者。在许多 OCR 指定产品中，如电影海报或电视罪案剧，角色可对应到这些原型，从而揭示意识形态价值。
4. Binary Opposition Formula | 二元对立公式
Lévi-Strauss: Meaning is produced through opposition. The core formula: Concept = Thesis A ⇌ Antithesis B → Cultural understanding
列维‑斯特劳斯：意义通过对立而产生。核心公式：概念 = 正题 A ⇌ 反题 B → 文化理解
Common media oppositions include: good ⇌ evil, young ⇌ old, civilisation ⇌ wilderness, male ⇌ female. The conflict between these binaries drives narrative and reinforces dominant ideology. When studying The Lego Movie video game or The Avengers, identify which binary oppositions structure the story and how they are eventually resolved or left open.
媒体中常见的二元对立包括：善 ⇌ 恶、年轻 ⇌ 年老、文明 ⇌ 荒野、男性 ⇌ 女性。这些二元之间的冲突推动叙事并强化主流意识形态。在学习《乐高大电影》电子游戏或《复仇者》时，要辨识出哪些二元对立构成了故事结构，以及它们最终如何被化解或悬置。
5. Encoding/Decoding & Preferred Reading Formula | 编码/解码与优选阅读公式
del: Meaning = Encoding (producer’s intended message) → Decoding (audience interpretation)
斯图尔特·霍尔的传播模型：意义 = 编码（生产者的意图信息）→ 解码（受众解读）
Three decoding positions exist: Preferred reading (audience accepts the intended meaning), Negotiated reading (partly accepts, partly resists), Oppositional reading (rejects the intended meaning entirely). In OCR exam questions, you must suggest how different audiences might decode the same media text, for example, a newspaper front page or a music video.
解码立场有三种：优选阅读（受众接受原意）、协商阅读（部分接受，部分抵抗）、对抗阅读（完全拒绝原意）。在 OCR 考题中，你必须指出不同受众可能如何解码同一个媒体文本，例如一份报纸头版或一支音乐视频。
6. The Male Gaze Formula | 男性凝视公式
Laura Mulvey’s cinematic gaze: Spectator = Male gaze → Woman = passive object of desire
劳拉·穆尔维的电影凝视：观众 = 男性凝视 → 女性 = 被动的欲望客体
The camera often positions the audience to look at women from a heterosexual male perspective. This can be seen in framing, lighting and costume choices. When analysing music videos or TV dramas for OCR, ask: Is the female body fragmented? Does the woman return the gaze or is she simply displayed? Contemporary texts sometimes subvert this formula with a female gaze or by challenging traditional beauty standards.
摄影机常常将观众置于异性恋男性的视角去观看女性。这可通过取景、布光和服装选择看出。在为 OCR 分析音乐视频或电视剧时，要问：女性身体是否被割裂？女性是否回视镜头，还是仅仅被展示？当代文本有时会以女性凝视或挑战传统审美标准的方式颠覆这一公式。
7. Uses and Gratifications Formula | 使用与满足公式
ons = Information + Personal Identity + Integration and Social Interaction + Entertainment
布鲁姆勒与卡茨：受众使用媒体来满足需求。公式：满足 = 信息 + 个人身份 + 整合与社交互动 + 娱乐
This active-audience model rejects the idea of passive consumption. For OCR, you might explain why teenagers choose a particular music video (personal identity, entertainment) or why older audiences read The Observer (information, integration). It also helps analyse online media, where audience members share, comment, and create content, thus gaining social interaction and a sense of community.
这一主动受众模型否定了被动消费的观念。对 OCR 而言，你可以解释为何青少年选择某支音乐视频（个人身份、娱乐），或为何年长受众阅读《观察家报》（信息、整合）。它也有助于分析网络媒体，受众在其中分享、评论并创作内容，从而获得社交互动和社群归属感。
8. Representation & Identity Formula | 表征与身份公式
General representation equation: Representation = Reality + Mediation + Ideology
一般表征方程式：表征 = 现实 + 中介 + 意识形态
l agency. Rather than simply reflecting the world, representations are constructed through selection, omission and framing. In the OCR set products, consider how teenagers, police officers, or celebrities are represented – and whose interests these representations serve.
戴维·冈特利特后来指出，媒体为受众提供了建构自我身份的工具：身份 = 媒体资源 × 个人能动性。表征并非简单地反映世界，而是通过选择、省略和取景来建构的。在 OCR 指定产品中，要思考青少年、警察或名人如何被表征，以及这些表征服务于谁的利益。
9. Media Industry & Synergy Formula | 媒体产业与协同公式
equation: Conglomeration + Vertical/Horizontal Integration + Synergy = Profit maximisation
柯伦与西顿：媒体所有权高度集中。权力等式：集团化 + 纵向/横向整合 + 协同 = 利润最大化
Synergy occurs when a conglomerate uses its subsidiaries to promote related products across different platforms. For example, a film, its video game tie-in and a soundtrack album all cross-promote one another. The OCR exam expects you to apply this to case studies like The Lego Movie franchise, which spans film, video games, toys and online content, all under one parent company. This formula explains why major studios prioritise established franchises over risky original ideas.
当传媒集团利用其子公司跨平台推广关联产品时，就产生了协同。例如，一部电影、其配套电子游戏和原声专辑彼此互推。OCR 考试要求你将此应用到《乐高大电影》系列的案例中，该系列横跨电影、电子游戏、玩具和网络内容，全都归属于同一家母公司。这一公式解释了为何大制片厂优先选择已有系列，而非冒险尝试原创。
10. Regulation & PSB Formula | 监管与公共服务广播公式
with consumer choice. The equation: Effective regulation = Protecting the public interest ⇌ Allowing market freedom
利文斯通与伦特：监管旨在平衡公民保护与消费者选择。等式：有效监管 = 保护公共利益 ⇌ 允许市场自由
Ofcom is the statutory regulator for UK media, required to uphold standards, protect audiences from harmful content, and ensure a plurality of viewpoints. Public Service Broadcasting (PSB) adds an obligation to inform, educate and entertain, distinct from purely commercial goals. For OCR, think about how changing technology (streaming, social media) challenges this formula: online platforms are far more difficult to regulate, which raises questions about media accountability.
Ofcom 是英国媒体的法定监管机构，必须维护标准、保护受众免受有害内容侵害，并确保观点多元化。公共服务广播（PSB）还增添了告知、教育和娱乐的义务，与纯粹商业目的区别开来。对 OCR 而言，要思考技术变革（流媒体、社交媒体）如何挑战这一等式：线上平台更难监管，这引发了媒体问责的质疑。
