📚 AQA Year 13 Science: Rapid Vocabulary Memorisation Guide | AQA 13年级科学：词汇术语速记指南
Mastering the specialised vocabulary of A-level Science can often feel like learning a foreign language. This guide is designed to help Year 13 students rapidly internalise key terms from Biology, Chemistry, and Physics by breaking down words into meaningful parts, uncovering their hidden roots, and applying proven memory techniques. With a focus on AQA specifications, you will not only memorise definitions but also truly understand the language of science.
掌握 A-level 科学的专业词汇常常感觉像在学一门外语。本指南旨在帮助 13 年级学生通过将单词分解为有意义的部分、发掘其隐藏的词根并应用经过验证的记忆技巧，快速内化来自生物、化学和物理的关键术语。结合 AQA 考试大纲，你不仅能记住定义，还能真正理解科学的语言。
1. The Power of Root Words and Etymology in Science | 科学中词根与词源的力量
Most scientific terms are built from Latin and Greek roots. Learning these building blocks is like acquiring a master key. For example, ‘photo’ means light, so photolysis, photosynthesis, and photoelectric all involve light. ‘Bio’ means life, giving us biology, antibiotic, and symbiosis.
大多数科学术语由拉丁语和希腊语词根构成。学习这些构建模块就像获得了一把万能钥匙。例如，’photo’ 表示光，因此光解、光合作用和光电效应都涉及光。’Bio’ 表示生命，衍生出生物学、抗生素和共生等词。
Once you recognise that ‘lysis’ means splitting, terms like glycolysis (splitting of sugar), photolysis (splitting by light), and hydrolysis (splitting by water) become instantly logical. This etymological approach transforms intimidating words into simple combinations of familiar parts.
一旦你认识到 ‘lysis’ 表示分裂，像糖酵解（糖的分解）、光解（由光引起的分解）和水解（由水引起的分解）这样的术语就立即变得合乎逻辑。这种词源学法将令人生畏的词汇转化为熟悉部分的简单组合。
A useful strategy is to keep a root-word journal. Whenever you encounter a new term, underline the root, research its meaning, and link it to similar words. This active engagement strengthens long-term memory far more effectively than rote repetition.
一个有用的策略是保持一本词根日记。每当你遇到一个新术语时，划出词根，研究其含义，并将其与相似的词联系起来。这种主动参与比死记硬背更能有效地增强长期记忆。
2. Physics: Mechanics and Fields Terminology | 物理：力学与场术语
In Year 13 mechanics, centripetal force often trips students up. Break it down: ‘centr-‘ (centre) and ‘petal’ (seeking, from Latin petere). A centripetal force is literally a centre-seeking force, always pointing towards the centre of circular motion. The closely related ‘centrifugal’ (‘fugal’ meaning fleeing) describes an apparent outward force felt in a rotating frame, not a real force in AQA physics.
在 13 年级力学中，向心力常让学生犯错。分解它：’centr-‘（中心）和 ‘petal’（寻求，源自拉丁语 petere）。向心力字面意思就是寻求中心的力，总是指向圆周运动的中心。与之密切相关的 ‘centrifugal’（’fugal’ 意为逃离）描述的是在旋转参考系中感受到的视在向外力，在 AQA 物理中并非真实存在的力。
Gravitational potential is defined as the work done per unit mass to bring a small test mass from infinity to a point. Memorise it by linking ‘potential’ to the idea of stored capability: a mass at a point in a gravitational field has the potential to do work. The negative sign, V = -GM/r, signifies that work is done by the field as a mass approaches, so the potential becomes more negative.
引力势定义为单位质量从无穷远移至某点时所做的功。通过将 ‘potential’ 与存储的能力联系起来记忆：引力场中某点的质量具有做功的潜力。负号 V = -GM/r 表示随着质量靠近，场做正功，因此势变得更负。
Escape velocity is the minimum speed an object needs to escape a planet’s gravitational pull without further propulsion. Remember it as the velocity to ‘escape’ the gravitational well. The formula v = √(2GM/r) can be recalled by noticing it is √2 times the orbital speed for a circular orbit at that radius.
逃逸速度是物体无需进一步推进就能逃脱行星引力所需的最小速度。记住它是为了 ‘escape’ 引力势井所需的速度。公式 v = √(2GM/r) 可通过注意到它是该半径处圆形轨道速度的 √2 倍来记忆。
3. Physics: Electricity, Capacitors and Quantum Phenomena | 物理：电学、电容器与量子现象
Capacitance is the charge stored per unit potential difference, C = Q/V. Think of a capacitor as a ‘capacity’ vessel for charge; a higher capacitance vessel stores more charge for the same voltage. The time constant τ = RC tells you how fast a capacitor charges or discharges, with 63% of the change occurring in one time constant.
电容是单位电势差下存储的电荷量，C = Q/V。把电容器想象成一个储存电荷的 ‘capacity’ 容器；电容越大，在相同电压下储存的电荷越多。时间常数 τ = RC 告诉你电容器充放电的快慢，63% 的变化发生在一个时间常数内。
The photoelectric effect provides crucial vocabulary. The work function (Φ) is the minimum energy needed to eject an electron from a metal surface. Photon (light quantum), threshold frequency (f₀), and stopping potential are linked by Einstein’s equation: hf = Φ + Ek(max). Remember that ‘photo’ (light) + ‘electric’ means electricity from light, and the ‘work function’ is the energy required to ‘work’ an electron out of the metal.
光电效应提供了重要词汇。功函数 (Φ) 是从金属表面发射电子所需的最小能量。光子（光量子）、阈频率 (f₀) 和遏止电势通过爱因斯坦方程联系起来：hf = Φ + Ek(max)。记住 ‘photo’（光）+ ‘electric’ 意为光生电，而 ‘work function’ 是将电子从金属中 ‘work’ 出来所需的能量。
Wave-particle duality reminds us that light and matter exhibit both wave-like and particle-like behaviour. The de Broglie wavelength λ = h/p treats momentum p as a wave property. ‘Duality’ simply means two-fold nature.
波粒二象性提醒我们光和物质既表现出波动性也表现出粒子性。德布罗意波长 λ = h/p 将动量 p 视为波动属性。’Duality’ 仅意味着双重性质。
4. Chemistry: Organic Chemistry Functional Groups | 化学：有机化学官能团
AQA Year 13 organic chemistry demands rapid recall of functional groups. Use mnemonic sequences. For the homologous series: Alkane (C-C single), Alkene (C=C), Alkyne (C≡C) – remember the ‘a, e, y’ progression. Alcohols end in -ol, aldehydes in -al, ketones in -one, carboxylic acids in -oic acid. The phrase ‘Oh My, Such Good Apple Pie’ can help recall: Ol (alcohol), My (maybe methyl), but better: ‘Alcohols and Aldehydes, Ketones and Carboxylic acids’ – associate the ‘A’ for Aldehyde and Alcohol.
AQA 13 年级有机化学要求快速回忆官能团。使用助记序列。对于同系列：烷烃 (C-C 单键)，烯烃 (C=C)，炔烃 (C≡C) – 记住 ‘a, e, y’ 的发展。醇类以 -ol 结尾，醛以 -al，酮以 -one，羧酸以 -oic acid。可以用短语帮助记忆，如 ‘Alcohols start with Al like Aldehydes, but Aldehydes end with al and Ketones with one.’
Carboxylic acid derivatives: acyl chloride, acid anhydride, ester, amide. Note that ‘acyl’ refers to the RCO- group. Anhydride means ‘without water’, formed by removing water between two acid molecules. Ester is from ‘ether’ of acids. Amide contains the -CONH₂ group relevant in proteins and nylon.
羧酸衍生物：酰氯、酸酐、酯、酰胺。注意 ‘acyl’ 指 RCO- 基团。Anhydride 意为 ‘无水’，由两个酸分子间失水形成。Ester 来自酸的 ‘醚’。酰胺含有 -CONH₂ 基团，与蛋白质和尼龙相关。
For benzene derivatives, ‘ortho-‘ (1,2), ‘meta-‘ (1,3), ‘para-‘ (1,4) are often memorised with ‘OMP’ order. Use a silly sentence: ‘Only Monkeys Play’ to sequence them. Phenol is benzene with -OH; phenylamine is benzene with -NH₂. The ‘phen’ root indicates phenyl ring.
对于苯的衍生物，’ortho-‘ (1,2), ‘meta-‘ (1,3), ‘para-‘ (1,4) 可用 ‘OMP’ 顺序记忆。用一句滑稽句：’Only Monkeys Play’ 来排序。苯酚是带 -OH 的苯；苯胺是带 -NH₂ 的苯。’phen’ 词根表示苯环。
5. Chemistry: Thermodynamics and Equilibrium Constants | 化学：热力学与平衡常数
Enthalpy (H) is the heat content of a system at constant pressure. The change ΔH is negative for exothermic (exit heat) and positive for endothermic (enter heat). Memorise by ‘exo’ meaning outside, ‘endo’ meaning inside. Entropy (S) is a measure of disorder. A positive ΔS means increased disorder, favoured by nature. The Gibbs free energy equation ΔG = ΔH – TΔS determines feasibility.
焓 (H) 是系统在恒压下的热含量。ΔH 为负表示放热（热量外出），为正表示吸热（热量进入）。通过 ‘exo’ 意为外，’endo’ 意为内来记忆。熵 (S) 是混乱度的量度。ΔS 为正值表示混乱度增加，为自然所喜好。吉布斯自由能方程 ΔG = ΔH – TΔS 决定了反应的可行性。
For equilibrium constant Kc, remember that for a reversible reaction aA + bB ⇌ cC + dD, Kc = ([C]^c [D]^d) / ([A]^a [B]^b). The trick ‘products over reactants’ is universal. However, Kc is only affected by temperature. The term ‘dynamic equilibrium’ reminds us that forward and backward rates are equal, but reactions are still ongoing.
对于平衡常数 Kc，记住对于可逆反应 aA + bB ⇌ cC + dD，Kc = ([C]^c [D]^d) / ([A]^a [B]^b)。’生成物除以反应物’ 的方法普遍适用。但 Kc 仅受温度影响。术语 ‘动态平衡’ 提醒我们正向和逆向速率相等，但反应仍在进行。
Electrode potentials E° are measured under standard conditions (298 K, 100 kPa, 1.0 mol dm⁻³). The more positive the E°, the greater the tendency to gain electrons (be reduced). The standard hydrogen electrode is the reference. Remember: ‘OIL RIG’ – Oxidation Is Loss, Reduction Is Gain of electrons.
电极电势 E° 在标准条件下（298 K，100 kPa，1.0 mol dm⁻³）测量。E° 越正，越倾向于获得电子（被还原）。标准氢电极是参考。记住：’OIL RIG’ – 氧化是失去电子，还原是得到电子。
6. Biology: Cellular Respiration and Photosynthesis | 生物：细胞呼吸与光合作用
Glycolysis literally means ‘sugar splitting’. This ten-step process in the cytoplasm splits glucose (6C) into two pyruvate (3C) molecules. Recall ‘glyco-‘ sweet, sugar, and ‘-lysis’ splitting. The link reaction converts pyruvate to acetyl CoA, releasing CO₂. Krebs cycle (also called citric acid cycle) occurs in the mitochondrial matrix and produces reduced NAD and FAD. Use the first-letter mnemonic ‘Citrate Is Krebs’ Substrate’ or simply associate with the scientist Hans Krebs.
糖酵解字面意思为 ‘糖的分解’。这个在细胞质中进行的十步过程将葡萄糖 (6C) 分解为两个丙酮酸 (3C) 分子。回忆 ‘glyco-‘ 甜、糖，以及 ‘-lysis’ 分裂。连接反应将丙酮酸转化为乙酰辅酶 A，释放 CO₂。克雷布斯循环（也称柠檬酸循环）发生在线粒体基质中，产生还原型 NAD 和 FAD。使用首字母助记 ‘Citrate Is Krebs’ Substrate’ 或简单地与科学家汉斯·克雷布斯联系。
Oxidative phosphorylation is the final stage where the electron transport chain creates a proton gradient for ATP synthase. The phrase ‘oxidative’ indicates oxidation of NADH/FADH₂, and ‘phosphorylation’ means adding phosphate to ADP. Photophosphorylation in photosynthesis is analogous but uses light energy to phosphorylate ADP. Photolysis of water splits H₂O using light, releasing O₂, electrons, and protons.
氧化磷酸化是最终阶段，电子传递链建立质子梯度以驱动 ATP 合酶。’oxidative’ 表示 NADH/FADH₂ 的氧化，’phosphorylation’ 表示给 ADP 加上磷酸基团。光合作用中的光合磷酸化类似，但利用光能使 ADP 磷酸化。水的光解利用光分解 H₂O，释放 O₂、电子和质子。
The Calvin cycle fixes CO₂ using RuBisCO. RuBisCO stands for Ribulose-1,5-bisphosphate carboxylase-oxygenase. Break it: Ribulose (sugar) + bisphosphate + carboxylase (adds CO₂) + oxygenase (can also react with O₂). For the light-dependent reactions, remember Z-scheme for electron flow.
卡尔文循环利用 RuBisCO 固定 CO₂。RuBisCO 代表核酮糖-1,5-二磷酸羧化酶/加氧酶。分解：核酮糖（糖）+ 二磷酸 + 羧化酶（加 CO₂）+ 加氧酶（也可与 O₂ 反应）。对于光依赖反应，记住电子流的 Z 方案。
7. Biology: Genetics, Gene Expression and Epigenetics | 生物：遗传、基因表达与表观遗传学
Transcription is the synthesis of mRNA from DNA. ‘Trans-‘ means across or transfer, and ‘script’ means write. So transcription is rewriting the genetic code from DNA to mRNA. Translation converts the mRNA code into a polypeptide sequence. Think of translating from the language of nucleotides to the language of amino acids.
转录是从 DNA 合成 mRNA 的过程。’Trans-‘ 意为跨或转移，’script’ 意为写。因此转录将遗传密码从 DNA 重写到 mRNA。翻译将 mRNA 密码转化为多肽序列。想象从核苷酸语言翻译为氨基酸语言。
Codons are three-base sequences on mRNA; anticodons are complementary on tRNA. Operons (like the lac operon) are clusters of genes under the same promoter. ‘Operon’ sounds like ‘operation’, and indeed it operates a coordinated set of genes. Epigenetics involves heritable changes in gene function without changes to the DNA sequence. ‘Epi-‘ means above or on top of, indicating changes above the genome level, like DNA methylation and histone modification.
密码子是 mRNA 上的三个碱基序列；反密码子是 tRNA 上的互补序列。操纵子（如乳糖操纵子）是在同一启动子下的基因簇。’Operon’ 听起来像 ‘operation’，确实它操纵着一组协调的基因。表观遗传学涉及基因功能的可遗传变化而不改变 DNA 序列。’Epi-‘ 意为在……之上，指示基因组水平之上的变化，如 DNA 甲基化和组蛋白修饰。
For inheritance, the terms homozygous, heterozygous, dominant, recessive, and codominance are fundamental. Use ‘homo’ (same) + ‘zygous’ (yoke) means same alleles; ‘hetero’ (different) means different alleles. Codominance is when both alleles are fully expressed, as in AB blood type.
对于遗传，纯合子、杂合子、显性、隐性和共显性是基本术语。使用 ‘homo’（相同）+ ‘zygous’（轭）表示相同等位基因；’hetero’（不同）表示不同等位基因。共显性是两个等位基因都完全表达，如 AB 血型。
8. Biology: Ecosystems, Populations and Energy Transfer | 生物：生态系统、种群与能量传递
An ecological niche is the role and position a species has in its environment, including all its interactions. Remember ‘niche’ as a species’ specialized ‘niche’ or job. Carrying capacity is the maximum population size an environment can sustain. Think of the environment ‘carrying’ the population; if exceeded, resources are depleted.
生态位是一个物种在其环境中的角色和地位，包括其所有相互作用。把 ‘niche’ 记作物种专门的 ‘niche’ 或工作。承载能力是环境能维持的最大种群数量。想象环境 ‘承载’ 着种群；若超越，资源将耗尽。
Succession describes the directional change in species composition over time. Primary succession starts on bare rock (pioneer species like lichens), leading to a climax community. The ‘sere’ denotes a stage. Use the sequence: pioneer -> intermediate -> climax. Energy transfer between trophic levels is typically 10%, owing to losses through respiration, excretion, and uneaten parts. The terms gross primary production (GPP) and net primary production (NPP = GPP – R) are essential. NPP is energy available to next trophic level.
演替描述了物种组成随时间的方向性变化。原生演替从裸岩开始（先锋物种如地衣），最终形成顶极群落。’sere’ 表示一个阶段。使用序列：先锋 -> 中间 -> 顶极。营养级之间的能量传递通常为 10%，由于呼吸、排泄和未食用部分的损失。总初级生产量 (GPP) 和净初级生产量 (NPP = GPP – R) 是必需的。NPP 是可提供给下一营养级的能量。
9. Common Prefixes, Suffixes and Root Words across the Sciences | 跨科学通用前缀、后缀和词根
Master a core set of prefixes to decode any term. ‘A-‘ or ‘an-‘ means without (asexual, anhydrous). ‘Anti-‘ against (antibiotic). ‘Auto-‘ self (autotroph). ‘Bi-‘ two (bipolar). ‘Bio-‘ life (biology). ‘Cyto-‘ cell (cytoplasm). ‘Di-‘ two (disaccharide). ‘Hyper-‘ over, above (hypertonic). ‘Hypo-‘ under, below (hypotonic). ‘Inter-‘ between (intermolecular). ‘Intra-‘ within (intramolecular). ‘Iso-‘ equal (isotonic). ‘Macro-‘ large (macromolecule). ‘Micro-‘ small (microorganism). ‘Mono-‘ one (monomer). ‘Poly-‘ many (polymer).
掌握一组核心前缀可以解码任何术语。’A-‘ 或 ‘an-‘ 表无（无性生殖、无水）。’Anti-‘ 抗（抗生素）。’Auto-‘ 自己（自养生物）。’Bi-‘ 二（双极）。’Bio-‘ 生命（生物学）。’Cyto-‘ 细胞（细胞质）。’Di-‘ 二（二糖）。’Hyper-‘ 超标、以上（高渗）。’Hypo-‘ 下面、以下（低渗）。’Inter-‘ 之间（分子间）。’Intra-‘ 之内（分子内）。’Iso-‘ 相等（等渗）。’Macro-‘ 大（大分子）。’Micro-‘ 小（微生物）。’Mono-‘ 一（单体）。’Poly-‘ 多（聚合物）。
Key suffixes: ‘-ase’ for enzymes (DNA polymerase). ‘-ose’ for sugars (glucose). ‘-itis’ inflammation, though more common in medicine. ‘-ide’ for binary compounds (chloride). ‘-ate’ for oxygen-containing ions (sulfate). ‘-logy’ study of. ‘-meter’ measuring device (thermometer). ‘-troph’ nourishment (autotroph, heterotroph).
关键后缀：’-ase’ 用于酶（DNA 聚合酶）。’-ose’ 用于糖（葡萄糖）。’-itis’ 炎症，更多在医学中。’-ide’ 用于二元化合物（氯化物）。’-ate’ 用于含氧离子（硫酸盐）。’-logy’ 学科。’-meter’ 测量仪器（温度计）。’-troph’ 营养方式（自养，异养）。
Combine these to interpret complex words: a heterotroph is an organism that gets ‘nourishment’ from ‘others’. A spectrophotometer is an instrument to measure light (photo) spectrum. An autotrophic cyanobacterium is a self-feeding blue-green bacterium. This morphological habit dramatically reduces memorisation burden.
组合这些来解释复杂词汇：异养生物是从 ‘其他’ 获取 ‘营养’ 的生物。分光光度计是测量光 (photo) 谱的仪器。自养的蓝细菌是一种自给营养的蓝绿色细菌。这种形态习惯显著减轻记忆负担。
10. Effective Memory Techniques: Acronyms, Chunking and Visual Association | 高效记忆技巧：首字母缩写、组块与视觉联想
Acronyms condense sequences into memorable words or phrases. For factors affecting enzyme activity: ‘PTSS’ – pH, Temperature, Substrate concentration, and Surface area is not perfect, but for biology ‘TPS’ (Temperature, pH, Substrate). For physics waves, ‘ROYGBIV’ for visible spectrum. Create personal acronyms that are bizarre, as the brain remembers unusual images better.
首字母缩写将序列浓缩成易记的单词或短语。对于影响酶活性的因素：’PTSS’ – pH、温度、底物浓度和表面积并不理想，但对于生物学可以用 ‘TPS’（温度、pH、底物）。对于物理波，’ROYGBIV’ 表示可见光谱。创造个人化的、荒诞的首字母缩写，因为大脑对不寻常的图像记忆更好。
Chunking involves breaking long terms into phonetic segments. Electro-magnetic-induc-tion becomes four chunks instead of 22 letters. Deoxyribonucleic acid becomes de-oxy-ribo-nucleic. Voltage-gated sodium ion channel is separated. Practice saying them rhythmically to build procedural memory.
组块法涉及将长术语分解为语音片段。Electro-magnetic-induc-tion 变成四个组块而不是 22 个字母。Deoxyribonucleic acid 变成 de-oxy-ribo-nucleic。电压门控钠离子通道分段。有节奏地读出来以建立程序性记忆。
Visual association or the method of loci can anchor terms. Imagine enthalpy (H) as a hot air balloon (heat content). Picture entropy (S) as a messy room getting messier. Link the Krebs cycle to a ‘Krebs-cycle-go-round’ fair ride where all steps happen. Draw a sketch, however crude, to solidify the mental model.
视觉联想或记忆宫殿法可以锚定术语。想象焓 (H) 是一个热气球（热含量）。把熵 (S) 想象成一个越来越乱的房间。将克雷布斯循环与一个 ‘克雷布斯旋转木马’ 游乐设施联系起来，所有步骤都在那里进行。画一个草图，无论多粗糙，都能巩固心理模型。
Finally, spaced repetition is scientifically proven. Use flashcards or apps to review terms at increasing intervals. Test yourself by explaining concepts aloud. Teaching a peer is one of the highest forms of mastery; if you can explain the term clearly, you own it.
最后，间隔重复是经过科学验证的方法。使用闪卡或应用程序以逐渐增大的间隔复习术语。通过大声解释概念来测试自己。教同伴是最高形式的掌握；如果你能清晰地解释术语，你就真正拥有了它。
