本手册汇集了你在 CCEA 九年级媒体研究中会遇到的最重要的“公式”与“定理”。从符号学的构成模块到剪辑的隐性规则和受众理论，这些概念等式和模型将帮助你精准地分析任何媒体文本。把每一个条目看作解码意义的工具——一份为提升作业和考试批判性能力的速查参考。
1. The Semiotic Foundation Formula | 符号学基础公式
The core of media language can be expressed as an equation: Signifier + Signified = Sign. The signifier is the physical form (a word, image, sound), the signified is the mental concept it triggers, and together they produce meaning.
媒体语言的核心可表达为一个等式：能指 + 所指 = 符号。能指是物理形式（词语、图像、声音），所指是其触发的心理概念，二者结合产生意义。
Signifier (a red rose image) + Signified (romance, love) = Sign (rose representing passion)
能指（红玫瑰图像）+ 所指（浪漫、爱情）= 符号（玫瑰代表热情）
Understanding this formula reminds us that nothing in media is ‘natural’: every element is constructed to guide our interpretation.
理解这个公式提醒我们：媒体中没有“自然”的东西——每个元素都是被建构出来以引导我们解读的。
2. Shot Size & Camera Angle Equation | 镜头尺寸与拍摄角度公式
The visual grammar of film and photography follows a reliable pattern: Shot Size + Camera Angle → Viewer Perception & Emotional Response. Changing either variable alters the relationship between audience and subject.
电影与摄影的视觉语法遵循一个可靠模式：镜头尺寸 + 拍摄角度 → 观众感知与情感反应。改变任何一个变量都会改变观众与被摄主体之间的关系。
- Extreme Close-Up (ECU) + High Angle = Vulnerability, being scrutinised | 极特写 + 俯角 = 脆弱、被审视
- Close-Up (CU) + Low Angle = Power, intensity, intimidation | 特写 + 仰角 = 力量、强度、威慑
- Long Shot (LS) + Eye Level = Context, observation, neutrality | 远景 + 平视 = 背景、观察、中性
- Wide Shot (WS) + Dutch Tilt = Disorientation, tension | 广角 + 斜角 = 迷失方向、紧张
By thinking in terms of this equation, you can quickly justify directorial choices during textual analysis.
用这套公式思考，你就能在文本分析中快速论证导演的选择。
3. Colour Psychology Formula | 色彩心理学公式
A powerful emotional palette can be decoded with: Hue × Saturation × Brightness = Visual Mood. These three dimensions collaborate to signal atmosphere and character psychology.
强大的情绪调色板可用如下公式解码：色相 × 饱和度 × 明度 = 视觉氛围。这三个维度共同作用，暗示氛围和角色心理。
| Hue (colour family) | Saturation | Resulting Mood |
| Red | High | Danger, passion, anger |
| Blue | Desaturated | Coldness, isolation, melancholy |
| Yellow | High, bright | Optimism, energy, warning |
| Green | Muted | Nature, sickness, envy |
When analysing posters, film scenes or branding, always note the dominant hue and its saturation level; together they build the ’emotional colour script’.
分析海报、电影场景或品牌时，始终要注意主色调及其饱和度；它们共同构建了“情绪色彩脚本”。
4. Todorov’s Narrative Equilibrium Theorem | 托多罗夫叙事平衡定理
Most mainstream media texts follow a five-stage structure that can be written as a balanced formula: Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium. This pattern satisfies our desire for order and resolution.
大多数主流媒体文本遵循五阶段结构，可写成平衡公式：平衡 → 打破 → 认知 → 尝试修复 → 新平衡。这一模式满足我们对秩序和结局的渴望。
Equilibrium (harmony) → Disruption (villain appears) → Recognition (hero realises problem) → Repair (quest) → New Equilibrium (peace restored but changed)
平衡（和谐）→ 打破（反派出现）→ 认知（主角意识到问题）→ 修复（探索）→ 新平衡（恢复和平但有所变化）
Applying this theorem helps you map the plot of any news story, advertisement or drama and identify where tension is created and released.
运用这条定理，你可以为任何新闻故事、广告或剧集绘制情节图谱，并识别紧张感在何处产生与释放。
5. Propp’s Character Function Formula | 普罗普角色功能公式
Vladimir Propp identified a set of recurring character roles in narratives, summarised as: Narrative = Sphere of Action of 7 Character Types. Each type performs a predictable function that drives the story forward.
弗拉基米尔·普罗普识别出叙事中反复出现的一组角色类型，概括为：叙事 = 7 种角色类型的行为范围。每种类型执行可预测的功能以推动故事。
- Hero: seeks something, often the protagonist | 英雄：追寻某物，通常是主角
- Villain: opposes the hero, creates disruption | 反派：对抗英雄，制造混乱
- Princess/Prize: the reward, often needs rescuing | 公主/奖赏：被追求的目标，常需拯救
- Dispatcher: sends the hero on the quest | 派遣者：派英雄踏上征程
- Donor: provides a magical object or wisdom | 捐赠者：提供法宝或智慧
- Helper: aids the hero on the journey | 帮手：在旅途中辅助英雄
- False Hero: claims credit but is exposed | 假英雄：冒领功劳，最终被揭穿
Recognising these ‘functions’ allows you to dissect the underlying architecture of films, adverts and even game narratives.
识别这些“功能”使你能够剖析电影、广告甚至游戏叙事中的深层架构。
6. The Continuity Editing Theorem | 连续性剪辑定理
To create a seamless flow of time and space, editors follow a strict set of rules that form a continuity theorem: 180° Rule + 30° Rule + Eyeline Match + Match on Action → Invisible Editing. Breaking any rule signals a deliberate stylistic or emotional disruption.
为创造流畅的时空流动，剪辑师遵循一套严格规则，构成连续性定理：180° 规则 + 30° 规则 + 视线匹配 + 动作接应 → 隐形剪辑。打破任何一条规则都暗示着特意的风格或情感断裂。
180° Rule (axis of action) maintains consistent screen direction; 30° Rule ensures a significant change in angle between shots to avoid jump cuts.
180° 规则（动作轴线）维持一致的屏幕方向；30° 规则确保镜头间角度有明显变化以避免跳切。
Applying this theorem in analysis means you can explain why a sudden crossing of the line disorients the audience or signals a character’s psychological shift.
分析中运用这一定理，你就能解释为何突然越轴会让观众迷失方向，或暗示角色心理转变。
7. The Kuleshov Effect & Montage Formula | 库里肖夫效应与蒙太奇公式
The foundational experiment of Soviet cinema demonstrated that meaning arises through juxtaposition: Shot A + Shot B → Inferred Meaning C. The same neutral face paired with different images (soup, coffin, child) generates hunger, grief or affection.
苏联电影的基础实验证明意义源于并置：镜头 A + 镜头 B → 推断意义 C。同一张中性面孔与不同图像（汤、棺材、孩子）结合，会产生饥饿、悲伤或疼爱之感。
Mozzhukhin’s neutral face + bowl of soup = audience reads ‘hunger’
莫兹尤辛的中性面孔 + 一碗汤 = 观众读出“饥饿”
This montage formula reminds us that editing is not merely joining shots but creating new conceptual wholes – a powerful tool in trailers, adverts and music videos.
这个蒙太奇公式提醒我们，剪辑不仅是连接镜头，而是创造新的概念整体——它是预告片、广告和音乐视频中的强大工具。
8. Sound Design Relationship Formula | 声音设计关系公式
Audio elements can be categorised by their alignment with the on-screen image using the formula: Sound Type = Synchronous / Asynchronous / Non-Diegetic. Each type constructs audience knowledge and atmosphere differently.
音频元素根据其与屏幕图像的对应关系可用公式归类：声音类型 = 同步声 / 非同步声 / 画外音。每种类型以不同方式构建观众认知和氛围。
- Synchronous sound: matched to action, e.g. footsteps heard as we see walking | 同步声：与动作匹配，如我们看到走路时听到脚步声
- Asynchronous sound: source visible in the story world but not synchronised, e.g. crowd noise while focusing on a silent character | 非同步声：声源在故事世界中可见但不同步，如聚焦沉默角色时听到人群噪音
- Non-diegetic sound: outside the story world, e.g. voice-over narration, background score | 画外音：故事世界之外的声音，如旁白解说、配乐
- Sound bridge: audio from the next scene begins before the visual transition, smoothing narrative flow | 声桥：下一场景的声音在画面切换前开始，平滑叙事流程
Using this formula, you can quickly label any audio element and discuss its function in creating empathy, tension or perspective.
使用这一公式，你可以快速标记任何音频元素，并讨论其在营造共情、紧张感或视角方面的功能。
9. Uses & Gratifications Audience Formula | 使用与满足受众公式
Audiences actively select media to satisfy specific needs. The theory can be presented as an additive model: Media Consumption = Information + Personal Identity + Social Interaction + Entertainment. Each component represents a gratification driver.
受众主动选择媒体以满足特定需求。该理论可呈现为加法模型：媒体消费 = 信息 + 个人认同 + 社交互动 + 娱乐。每个组成部分代表一种满足驱动力。
| Gratification | Example |
| Information / surveillance | News apps, documentaries, how-to videos |
| Personal identity | Music playlists that reflect mood, Instagram role models |
| Social interaction / integration | Commenting on YouTube, sharing TikToks, fandom groups |
| Entertainment / diversion | Netflix binge-watching, gaming, meme scrolling |
Remember that a single media text can deliver multiple gratifications simultaneously – a survival show, for instance, might inform, build community and entertain.
记住，一个媒体文本可以同时提供多重满足——比如一个求生节目可能既有信息性，又能建立社群，还能娱乐。
10. The AIDA Persuasion Formula in Advertising | 广告说服公式 AIDA
Advertising creativity is often structured around a psychological sequence: Attention → Interest → Desire → Action. This linear model tracks the cognitive journey a consumer takes from ignorance to purchase.
广告创意常围绕一个心理序列构建：注意 → 兴趣 → 欲望 → 行动。这个线性模型追踪了消费者从不知情到购买的认知旅程。
Attention (bold headline, striking image) → Interest (benefits highlighted) → Desire (emotional appeal, lifestyle association) → Action (call to buy, click link)
注意（大胆标题、醒目图像）→ 兴趣（突出好处）→ 欲望（情感诉求、生活方式联想）→ 行动（购买号召、点击链接）
When deconstructing print, TV or social media ads, map each element onto the AIDA stages to explain how the text tries to move the target audience.
解构平面、电视或社交媒体广告时，将每个元素对应到 AIDA 阶段，以解释文本如何试图推动目标受众。
11. Representation & Stereotype Theorem | 表征与刻板印象定理
All media representations are re-presentations of reality, governed by a selection and construction process. The relationship can be expressed as: Representation = Reality – Omission + Mediation. When a group is repeatedly simplified, a stereotype forms: Stereotype = Overgeneralised Trait × Repeated Exposure.
所有媒体表征都是对现实的重现，受选择和建构过程支配。这种关系可表达为：表征 = 现实 – 省略 + 中介。当一个群体被反复简化时，刻板印象便形成：刻板印象 = 过度概括的特征 × 反复曝光。
Stereotype (teenagers as moody and lazy) = repeated media portrayals that reduce complexity
刻板印象（青少年情绪化且懒惰）= 反复出现的媒体描绘，削减了复杂性
Counter-stereotypes challenge this theorem by introducing nuance, but they still operate within the same representational system. Always ask: who constructed this image, and what has been left out?
反刻板印象通过引入细微差别挑战这一定理，但它们仍在同一表征体系中运作。始终要问：谁建构了这一形象，又省略了什么？
12. Media Institution Flow Formula | 媒体制度流程公式
The journey of a media product from idea to audience can be modelled as a circular flow: Production → Distribution → Exhibition → Consumption → Feedback. Understanding this industrial logic reveals how economic and regulatory factors shape content.
媒体产品从创意到受众的旅程可模拟为一个循环流程：制作 → 发行 → 展示 → 消费 → 反馈。理解这一产业逻辑可以揭示经济与监管因素如何塑造内容。
Production (studio, publisher) → Distribution (broadcaster, streaming platform) → Exhibition (cinema, app store, newsstand) → Consumption (audience views, reads) → Feedback (ratings, reviews, sales data)
制作（制片厂、出版社）→ 发行（广播公司、流媒体平台）→ 展示（影院、应用商店、报摊）→ 消费（受众观看、阅读）→ 反馈（收视率、评论、销售数据）
This formula helps you move beyond textual analysis alone and consider the wider systems of power, ownership and regulation that determine which stories get told.
这个公式帮助你超越单纯的文本分析，去思考决定哪些故事得以被讲述的更广泛的权力、所有权和监管体系。
