Engineering Writing — 工程师英文写作
本质 工程写作的核心不是修饰,是消除歧义——让审稿人 / 同事 / 客户读完不困惑。每段一个论点、每段开头一句概述、每句一个动作;被动语态用在"操作过程",主动用在"结论与判断"。中国工程师常踩 3 个坑: ① 过度被动("It can be observed that...");② 句子嵌套太深(3 层从句让人迷路);③ 重复啰嗦(说同一件事 3 次)。英文工程写作 = 信息密度最大化——同样信息,字越少越好。本页围绕"paper / report / memo 三种文体 + 句子级清晰原则 + active vs passive + 段落逻辑 + 4 种 Chinglish + 反模式"6 个维度。
学习目标
读完本页后,你应该能够:
- 写一段 paper abstract(problem / approach / result / impact)
- 区分 active vs passive voice 的技术语境用法
- 用 5 种 transition phrase 让段落之间逻辑顺畅
- 避免 4 种常见 Chinglish 句法
- 写一份 1 页 technical memo
- 识别 5 个工程写作反模式
1. 三种工程写作体裁
工程师写作主要 3 种文体 —— paper / report / memo。3 种长度、读者、目的不同,对应不同的写法。
| 文体 | 读者 | 长度 | 重点 |
|---|---|---|---|
| Paper | 同行评审 | 8-15 页 | 创新点 + 严谨论证 |
| Report | 技术客户 / 老板 | 5-50 页 | 数据 + 结论 + 建议 |
| Memo | 团队内部 | 1-2 页 | 立场 + 行动 |
2. Paper Abstract 公式
Paper abstract 走固定 4 段公式 —— problem / approach / result / impact。每段 1-2 句,共 150-250 字。中国作者常头重脚轻(背景写半页,结论一句话),好 abstract 是反过来的。
2.1 4 段各自的写法
每段有固定的字数 + 内容要点 + 关键句式——4 段缺一不可,字数控制是 abstract 难点。
| 段 | 字数 | 内容要点 | 关键句式 |
|---|---|---|---|
| Problem | 30-50 字 | 现状 / 难题 / 为什么重要 | "X remains a key challenge in..." |
| Approach | 40-60 字 | 用了什么方法 | "We propose a novel X based on Y..." |
| Result | 40-60 字 | 量化结果(具体数字) | "Experiments show a 35% improvement..." |
| Impact | 30-50 字 | 应用 / 拓展 | "This enables X in scenarios such as..." |
2.2 完整 abstract 例
(Problem) Switching losses dominate efficiency in 800 V SiC inverters at high switching frequencies, yet existing gate-driver designs trade off speed against ringing immunity in ways that constrain converter density. (Approach) This paper presents an active gate driver that adaptively shapes V_GS during the Miller plateau, using on-chip current sensing to detect di/dt and modulate Rg in three discrete stages within 50 ns. (Result) Measurements on a 100 kW double-pulse test rig show a 28% reduction in turn-on energy and a 41% reduction in V_DS overshoot compared with a fixed Rg baseline, while maintaining a 5 V/ns minimum dV/dt. (Impact) The technique generalises to any wide-bandgap device facing the same speed-vs-stability trade-off, offering a path toward higher-density traction inverters without compromising reliability.
注意:② Approach 没说"我们先做了 A 再做 B"(过程),只说"做了什么";③ Result 用 28% / 41% 等具体数字,不是"显著提升"。
2.3 Abstract 反模式
中国作者写 abstract 最常踩 4 个反模式——背景过长、缺数据、用未来时态、用第一人称单数。
| 反模式 | 修法 |
|---|---|
| 背景过长 | 30-50 字够,不要写半页 |
| 缺数据 | 必须有具体数字 |
| 未来时态 | "We propose..."用 present,不用 will |
| 第一人称单数 | 用 "we / this paper",不用 "I" |
3. 句子级清晰原则
工程写作的核心是句子层面的清晰。下面 6 条原则是 Strunk & White 和 Pinker 总结的精华。
3.1 6 条清晰原则
句子级清晰靠 6 条独立原则——短句、主动、强动词、具体名词、删冗余、平行。这 6 条覆盖 90% 句子改写场景。
| 原则 | 说明 |
|---|---|
| 短句优先 | 平均 18-22 词 / 句;超过 30 词必须拆 |
| 主动当主语动作 | "We tested" > "Testing was performed" |
| 强动词 | "demonstrate" > "show that there is evidence of" |
| 具体名词 | "the inverter" > "the system" |
| 删冗余 | "in order to" → "to";"a number of" → "several" |
| 平行结构 | "fast, accurate, and reliable"(同词性) |
3.2 删冗余对比
下面 10 组几乎所有中国作者都在用啰嗦版 —— 改成简洁版即可,无信息损失。
| 啰嗦版 | 简洁版 |
|---|---|
| in order to | to |
| due to the fact that | because |
| at the present time | now |
| a number of | several / many |
| in the event that | if |
| in spite of the fact that | although |
| make a decision | decide |
| conduct an investigation of | investigate |
| has the ability to | can |
| in close proximity to | near |
每条删除节省 3-5 字 —— 一篇 8 页 paper 累计删 200-400 字,信息密度提升 5-10%。
3.3 强动词替代弱动词组
弱动词组(动词 + 名词)几乎都能用单个强动词替代:
| 弱组合 | 强动词 |
|---|---|
| make a contribution | contribute |
| perform an analysis | analyse |
| make a comparison | compare |
| have an effect on | affect |
| reach a conclusion | conclude |
| make a recommendation | recommend |
| give consideration to | consider |
| have knowledge of | know |
| make use of | use |
| be in agreement with | agree with |
4. Active vs Passive Voice
中国工程师严重过度被动——觉得"被动客观"。实际上 active 更强 + 更短 + 更清晰。下面给出技术写作里两者的正确分工。
4.1 何时用 active
Active voice 用在"作者主动表达观点 / 判断" 的场景 —— 4 类典型场景如下。
| 场景 | 例 |
|---|---|
| 作者的贡献 / 论点 | We propose / This paper presents |
| 对结果的判断 | We argue that... / This indicates... |
| 强调主语 | The algorithm outperforms baseline by... |
| 对比 / 强调差别 | A converges faster than B because... |
4.2 何时用 passive
Passive voice 用在"过程 / 观察 / 不需强调主体" 的场景 —— 4 类典型场景如下。
| 场景 | 例 |
|---|---|
| 操作 / 实验过程 | The samples were heated to 300°C |
| 不确定主语 | A 2 dB increase was observed |
| 强调对象而非动作主体 | The driver IC is integrated on the same die |
| 历史 / 已知事实 | Si MOSFETs have been used since the 1970s |
4.3 平衡原则
理想分布: active 60-70% / passive 30-40%。中国论文常 90% passive,被审稿人指出"too passive"。修法: 把所有 "It can be observed / It is shown / It is concluded" 重写成 "We observe / We show / We conclude"(论文) 或 "Results show / The data demonstrates"(无 we 时)。
5. 段落逻辑
5.1 Topic Sentence 优先
每段第一句必须是 topic sentence——告诉读者"本段讲什么"。剩下的句子支撑或展开 topic sentence。
反例: "The signal is sampled at 10 MHz. Then it is filtered. The filter is FIR. The cutoff is 1 MHz. This gives the desired bandwidth."(无 topic sentence)
正例: "The front-end signal chain achieves 1 MHz noise-limited bandwidth through a three-stage approach. First, ... Second, ... Finally, ..."(topic sentence + 支撑)
5.2 5 种段落过渡 phrase
段落之间用 5 种 transition pattern——每种适合不同逻辑关系。
| 逻辑 | Phrase |
|---|---|
| 延伸 | Building on this, ... / This extends to... |
| 对比 | In contrast, ... / By contrast, ... |
| 因果 | Consequently, ... / This results in... |
| 让步 | Despite this, ... / Nevertheless, ... |
| 举例 | A case in point is... / Take, for instance, ... |
避免: Firstly / Secondly / Thirdly —— 这是 7 分以下水准。8+ 分用上面 5 种自然过渡。
5.3 段尾的 sign-off
每段结尾最好有 sign-off 句——总结本段或衔接下段。
例: "These results demonstrate that the proposed approach is viable; the next section examines its sensitivity to component tolerances."
注意: 不要每段都 sign-off,否则机械。重要段(introducing / concluding)必有,中间段可省。
6. 4 种常见 Chinglish 句法
中国工程师最常出现的 4 类 Chinglish 句法——这 4 类一旦出现,审稿人立刻识别 non-native 作者。
6.1 双否定不当
中文允许"不无道理"这类双否定,英文里双否定一旦不自然就显得做作——下面是常见的 Chinglish 双否定及其修法。
| Chinglish | Native |
|---|---|
| "It is not without merit." | "It has merit." / "It is meritorious." |
| "Not unlike the previous case..." | "Similar to the previous case..." |
6.2 主语过长
中文句子主语可以很长(N 个修饰),但英文主语长会让谓语找不到。
Chinglish: "The previously developed in our last paper highly accurate noise model based on stochastic differential equations demonstrates that..."
Native: "The noise model developed in our last paper, based on stochastic differential equations, demonstrates that..."(把修饰拆到主语后)
6.3 信息倒置
中文常"背景 → 重点",英文常"重点 → 细节"。
Chinglish: "Considering the high temperature, the increasing complexity, and the cost constraints in modern automotive systems, a new approach is needed."
Native: "A new approach is needed because of three constraints in modern automotive systems: high temperature, increasing complexity, and cost."
6.4 时态混乱
中文无时态,英文严格区分。
Chinglish: "We propose a method. We test it on 5 cases. The results show 10% improvement."(全 present)
Native: "We propose a method, test it on 5 cases, and find a 10% improvement."(并列动词,present;或全过去式描述实验)
7. Technical Memo 写法
Memo 是工程师内部高频文体——1-2 页给老板 / 团队 / 客户的简短报告。重点是立场 + 行动,不是综述。
7.1 Memo 标准结构
Memo 走固定 6 段结构 —— 头部 + opening + background + analysis + recommendation + next steps。每段长度严格控制,1-2 页内信息密度最大化。
TO: [recipient]
FROM: [sender]
DATE: [date]
SUBJECT: [one-line summary, action-oriented]
OPENING: [立场 / 关键发现, 1 段 50 字]
BACKGROUND: [必要 context, 1 段 80 字]
ANALYSIS: [核心论证, 2 段共 200 字]
RECOMMENDATION: [具体行动 / 决策, 1 段 60 字]
NEXT STEPS: [谁做什么 / 何时, 列表]
7.2 Subject line 公式
Subject 必须是 action-oriented —— 不是描述,是请求 / 决策。
| 弱 subject | 强 subject |
|---|---|
| "Update on Project X" | "Project X: Recommendation to Proceed with Option B" |
| "Test results" | "Test results show 30% efficiency drop — investigation needed" |
| "Meeting notes" | "Decisions from Sept 15 meeting: Q4 priorities locked" |
强 subject 让读者 2 秒内知道是否需要采取行动。
7.3 Opening paragraph 范例
"Following last week's failure analysis on Unit #7, we recommend halting Phase-2 production until the root cause is confirmed. Initial findings point to a wire-bond crack triggered by ΔT_j > 100 °C cycling under field load, but lab confirmation is pending. This memo summarises the evidence to date and proposes a 3-week investigation plan."
注意:第一句就给立场("recommend halting")——不要把立场埋到第 5 段。
8. 5 个工程写作反模式
工程写作失分 / 被审稿人指出集中在 5 个反模式——这 5 个修好后,工程写作清晰度提升 1-2 个层次。
| 反模式 | 表现 | 修法 |
|---|---|---|
| 过度被动 | 90%+ passive | 把作者贡献 / 判断改 active |
| 句子嵌套 | 3 层从句 + 介词链 | 拆成 2-3 个短句 |
| 冗余啰嗦 | "in order to / due to the fact that..." | 用简洁版 |
| 缺 topic sentence | 段落开头跳进细节 | 每段第一句必须 topic sentence |
| 数据缺失 | "showed improvement"(无具体数字) | 必须有 X% / Y dB / Z s 等 |
8.1 句子嵌套为什么是反模式
中文允许"X 的 Y 的 Z 的 W"嵌套——英文超过 2 层就让读者迷路。
反例: "The driver IC, which is designed to control the gate of the SiC MOSFET, which is used in the inverter, which is connected to the motor that powers the wheels of the vehicle, has a propagation delay of..."
正例: "The driver IC controls the gate of the SiC MOSFET in the traction inverter. Its propagation delay is..."
原则: 每句最多 1 层从句,2 层从句必须拆。
