1. Semiotics Formula: Signifier + Signified = Sign | 符号学公式：能指 + 所指 = 符号

Media texts are built from signs. A sign is created when a physical signifier (an image, word, or sound) meets a mental concept (the signified). This combination produces meaning that is shared within a culture. For example, a red rose (signifier) combines with the idea of romance (signified) to create the sign 'love'. Understanding this formula helps you decode the hidden messages behind every detail on screen.

媒体文本由符号构成。当可感知的能指（图像、词语或声音）与心理概念（所指）相遇时，符号便产生了。这种结合创造出在一种文化中共享的意义。例如，红玫瑰（能指）与浪漫的观念（所指）组合，产生了“爱”这个符号。理解这个公式有助于你解码屏幕上每个细节背后的隐藏信息。

2. Narrative Structure Theorem: Equilibrium → Disruption → New Equilibrium | 叙事结构定理：平衡 → 打破 → 新平衡

According to Todorov's theorem, most stories follow a five‑stage pattern: a state of equilibrium is disrupted by an event, the disruption is recognised, an attempt is made to repair the damage, and a new equilibrium is restored. This formula can be applied to anything from a news bulletin to a superhero movie. Recognising each stage lets you predict plot turns and understand how media constructs order out of chaos.

根据托多罗夫的定理，大多数故事遵循五阶段模式：平衡状态被事件打破，混乱被识别，主人公尝试修复损害，最终恢复一个新平衡。这个公式适用于从新闻简报、超级英雄电影到广告的一切叙事。识别每个阶段能让你预判情节转折，并理解媒体如何从混乱中建构秩序。

3. Character Function Theorem: The 7 Character Roles by Propp | 角色功能定理：普罗普的七种角色

Vladimir Propp analysed folk tales and identified seven recurring character functions: the hero, the villain, the donor, the helper, the princess (and her father), the dispatcher, and the false hero. These roles act like a formula; swap in different faces and settings, and the story engine still runs. Spotting these roles in a TV drama or video game helps you see how characters are engineered to drive the plot.

弗拉基米尔·普罗普分析民间故事后归纳出七种反复出现的角色功能：英雄、反派、赠与者、帮手、公主（及其父亲）、派遣者和假英雄。这些角色就像公式一样，替换不同的面孔和背景，故事引擎照样运转。在电视剧或电子游戏中识别这些角色，能帮你看清人物是如何被设计来推动剧情的。

4. Shot Size Formula: Frame = Emotional Distance | 镜头尺寸公式：画框 = 情感距离

The distance between the camera and the subject controls how close we feel to a character. An extreme long shot (ELS) establishes location, a long shot (LS) shows the body and surroundings, a mid shot (MS) mimics conversation distance, a close‑up (CU) reveals emotion, and an extreme close‑up (ECU) intensifies detail, often creating tension. Use this formula: the tighter the frame, the greater the intimacy or unease.

摄影机与被摄体之间的距离控制着我们觉得与角色有多亲近。极远景用于建立场景，远景展示身体与环境，中景模仿对话距离，特写揭示情感，而极特写强化细节并常常制造紧张感。运用这个公式：画框越紧，亲密感或不安感就越强。

5. Camera Angle Theorem: High = Vulnerability, Low = Power | 摄影角度定理：俯拍 = 脆弱，仰拍 = 权力

Angles shape power dynamics. A high‑angle shot looks down on a character, making them appear small, weak, or trapped. A low‑angle shot looks up, giving the subject dominance, authority, or menace. Eye‑level angles suggest equality. Dutch (canted) angles signal confusion or unease. By identifying the angle, you can quickly read who a scene wants you to respect or fear.

角度塑造权力关系。俯拍镜头向下看人物，使其显得渺小、虚弱或受困。仰拍镜头向上看，赋予拍摄对象支配感、权威或威胁感。平视角度暗示平等。斜角则传递混乱或不安。通过识别角度，你能快速读懂场景希望你尊敬或害怕谁。

6. Editing Rhythm Theorem: Fast Cuts = Energy, Slow Cuts = Reflection | 剪辑节奏定理：快切 = 活力，慢切 = 沉思

Editing pace operates like a tempo formula. Rapid cuts create excitement, urgency, or chaos — think of a car chase or a music video. Slow, longer takes invite contemplation, sadness, or tension. Transitions also matter: a dissolve may suggest passing time, while a jump cut can jolt the viewer. Mastering this theorem lets you explain why a video feels the way it does.

剪辑节奏就像速度公式。快速剪切能制造兴奋、紧迫或混乱——想想飙车戏或音乐视频。缓慢的长镜头则引发沉思、悲伤或紧张。转场也很重要：叠化可能暗示时光流逝，而跳切可以给观众带来冲击。掌握这一定理，你就能解释一段视频之所以给人以特定感受的原因。

7. Sound Layering Formula: Diegetic + Non‑diegetic = Immersion | 声音分层公式：叙境内 + 叙境外 = 沉浸感

Sound in media is crafted by layering diegetic audio (sounds that exist in the story world, like footsteps or dialogue) with non‑diegetic audio (sounds added for the audience, like a film score or voice‑over). This formula builds atmosphere and guides audience emotion. For instance, a tense scene may pair diegetic heavy breathing with non‑diegetic, pulsing music to heighten suspense.

媒体中的声音是通过将叙境内音频（存在于故事世界中的声音，如脚步声或对话）与叙境外音频（仅为观众添加的声音，如电影配乐或画外音）层层叠加而精心制作出来的。这个公式能营造氛围并引导观众情绪。例如，一场紧张戏可能会让叙境内的沉重呼吸音配上叙境外跳动的配乐，以增强悬念。

8. Mise‑en‑scène Theorem: Everything in Frame Speaks | 场面调度定理：画框中一切皆有所言

Mise‑en‑scène means 'placed on stage' and refers to everything visible within the frame: setting, props, lighting, costume, makeup, and figure positioning. The theorem is that no element is accidental. A dimly lit alley with scattered props signals danger, while soft golden lighting and tidy furniture suggest warmth and safety. Analysing these details reveals how directors build meaning visually.

场面调度意为“置于场景中”，指画框内可见的一切：布景、道具、灯光、服装、化妆和人物站位。这一定理表明，没有任何元素是偶然的。一条灯光昏暗、道具散乱的小巷暗示着危险，而柔和的金色光线和整洁的家具则传递出温暖与安全。分析这些细节，就能揭示导演如何通过视觉建构意义。

9. Uses and Gratifications Formula: Media Appeal = 4 Needs | 使用与满足公式：媒体吸引力 = 四种需求

This audience‑centred formula states that people actively choose media to satisfy four needs: information (learning or staying informed), personal identity (reinforcing values or finding role models), integration and social interaction (feeling connected to others), and entertainment (escapism or relaxation). When analysing an advert or a YouTube channel, ask which need it targets: a news app serves information, while a comedy panel show blends entertainment and social interaction.

这个以受众为中心的公式指出，人们主动选择媒体来满足四种需求：信息（学习或掌握资讯）、个人认同（强化价值观或寻找榜样）、整合与社交互动（与他人建立连接感）以及娱乐（逃避现实或放松）。分析一个广告或YouTube频道时，不妨问一句它在瞄准哪种需求：新闻App提供的是信息，而喜剧脱口秀则融合了娱乐与社交互动。

10. Encoding/Decoding Theorem: Preferred, Negotiated, Oppositional Readings | 编码/解码定理：主导式、协商式与对抗式解读

Stuart Hall's theorem explains that media producers encode a preferred meaning into a text, but audiences do not simply absorb it. They may accept the intended message (preferred reading), partly accept and modify it (negotiated reading), or completely reject it using their own experiences (oppositional reading). This theorem reminds you that the same music video can be interpreted in multiple, equally valid ways.

斯图亚特·霍尔的定理说明，媒体生产者将一种主导意义编码到文本中，但受众并非单纯吸收。他们可能接受预期的信息（主导式解读），部分接受并进行调整（协商式解读），或运用自身经验完全抵制（对抗式解读）。这个定理提醒你，同一部音乐视频可以有多种同样合理的解读方式。

11. Representation Theorem: Mediation = Selection + Construction | 表征定理：中介 = 选择 + 建构

Media does not mirror reality; it represents it by selecting and combining elements. This theorem states that every representation — of a teenager, a family, or a place — is a constructed version shaped by the producer's choices, cultural norms, and technical codes. Stereotypes are shortcuts that can reinforce or challenge ideas. Deconstructing representation means asking: who is shown, how, and who is left out.

媒体并非镜子般反映现实，而是通过选择和组合元素来表征现实。这一定理表明，每一种表征——无论是对青少年、家庭还是某个地方的描写——都是一种被建构出来的版本，受到生产者选择、文化规范和技术符码的塑造。刻板印象是一种捷径，既能强化也能挑战既有观念。解构表征意味着追问：谁被呈现？如何呈现？谁被排除在外？

12. Target Audience Formula: Demographics + Psychographics = Content | 目标受众公式：人口统计 + 心理志趣 = 内容

Media producers design content by blending demographics (age, gender, income, location) with psychographics (values, interests, lifestyle). This formula explains why a teen drama uses quick editing, pop music, and school‑based storylines — the content is tailored to a psychographic profile of adventure‑seeking, peer‑focused youth. Pinpointing the formula helps you reverse‑engineer who a media product is really for.

媒体生产者通过混合人口统计特征（年龄、性别、收入、地点）与心理志趣（价值观、兴趣、生活方式）来设计内容。这个公式解释了为什么青春剧会运用快节奏剪辑、流行音乐和校园故事线——内容是为了迎合追求冒险、重视同伴关系的青少年心理画像而量身定做的。精确识别这一公式能帮你逆向推导出一件媒体产品真正是为谁打造的。
