撰写技术报告是 SQA 13年级工程评估的核心。本文提供一个清晰的结构框架和带注释的范文，帮助你自信地完成项目报告。我们将逐一讲解每个关键部分，从标题页到附录，确保你的作品符合评分标准并展现出深刻的分析思维。
1. Understanding the SQA Report Requirements | 理解 SQA 报告要求
Before writing, you must decode the SQA specification. The report is not just a diary of your practical work; it is an argument. You need to show how you applied engineering principles, analysed data, evaluated outcomes, and justified decisions. Marks are allocated for analysis (around 40%), evaluation (30%), and presentation (20%), with the remainder for practical skills evidence. Every sentence should aim to earn credit in these categories.
动笔之前，你必须解读 SQA 的评分规范。报告不仅是对实践工作的记录，更是一个论证过程。你需要展示如何应用工程原理、分析数据、评估结果并论证决策。评分按分析（约40%）、评价（30%）和呈现（20%）分配，其余为实践技能证据。每一句话都应力争在这些类别中获得分数。
- Analysis (A): Breaking down systems, comparing alternatives, interpreting graphs, using calculations with correct units. 分析 (A)： 拆解系统、比较方案、解读图表、使用带正确单位的计算。
- Evaluation (E): Critically judging success, discussing limitations, suggesting improvements, linking back to specifications. 评价 (E)： 批判性地判断成功之处、讨论局限性、提出改进建议、回扣技术规格。
- Presentation (P): Clear structure, formal language, labeled diagrams, consistent formatting, referencing. 呈现 (P)： 结构清晰、语言正式、图示带标注、格式一致、规范引用。
2. Overall Report Structure | 报告总结构
A winning SQA engineering report typically contains the following sections in order. This flow mirrors professional engineering documentation and helps examiners follow your logical process quickly.
一份优秀的 SQA 工程报告通常按顺序包含以下部分。这种流程仿照专业工程文档，有助于考官快速理解你的逻辑过程。
| Section | Purpose |
| Title Page | Identifier: title, candidate number, centre |
| Abstract / Summary | Standalone synopsis of aims, methods, findings |
| Contents Page | Navigational aid |
| Introduction | Context, problem statement, specification, objectives |
| Research & Theory | Relevant principles, prior art, design rationale |
| Design/Analysis/Methods | Your approach, calculations, simulations, manufacturing |
| Results | Measured data, observations, graphs (no interpretation yet) |
| Discussion/Evaluation | Interpretation, comparison to theory, error analysis, critique |
| Conclusions | Succinct answer to objectives, final judgement |
| References & Appendices | Sources cited, detailed data sheets, CAD drawings, code |
3. The Abstract: Your Elevator Pitch | 摘要：你的电梯演讲
Write the abstract last, but place it at the front. In 150–200 words, summarise the project's aim, the key methodology, the main numerical results (with units), and the principal conclusion. Use past tense and avoid abbreviations. This is the examiner's first deep look at your competence.
摘要最后写，但放在最前面。用150–200字概括项目目标、关键方法、主要量化结果（带单位）和主要结论。使用过去时态，避免缩写。这是考官深入了解你能力的第一扇窗。
Sample abstract snippet: "This project designed, built, and tested a small-scale wind turbine to investigate the relationship between blade pitch angle and power output. A rig using a 3D-printed hub and Arduino-based data logger recorded voltage and current at wind speeds of 4–8 m/s. The optimal pitch angle was found to be 12°, yielding a peak power of 2.4 W at 7.5 m/s, with an efficiency of 18%. The prototype met the specification for safe operation but fell 12% short of the 20 W target, mainly due to generator friction losses."
摘要片段示例：“本项目设计、搭建并测试了一台小型风力涡轮机，以研究叶片桨距角与输出功率之间的关系。使用3D打印轮毂和基于Arduino的数据记录器，在4–8 m/s的风速下记录电压和电流。实验发现最优桨距角为12°，在7.5 m/s时达到峰值功率2.4 W，效率18%。样机满足安全运行规范，但比20 W目标低12%，主要由于发电机摩擦损失。”
4. Introduction: Setting the Scene | 引言：铺垫背景
Begin broadly, then narrow to your specific problem. State the client or end-user need (if applicable), link to real-world applications, and present a clear Design Specification or Project Brief. The Introduction must close with a numbered list of measurable objectives. For SQA, objectives should be SMART (Specific, Measurable, Achievable, Relevant, Time-bound).
从大背景入手，逐渐聚焦到具体问题。陈述客户或终端用户需求（如适用），联系实际应用，并给出清晰的设计规范或项目概要。引言末尾必须列出编号的可量化目标清单。对于SQA，目标需符合SMART原则（具体、可测量、可实现、相关、有时限）。
Example objectives:
目标示例：
- Design a bridge structure from balsa wood spanning 600 mm, capable of supporting a central load of 15 kg with a safety factor of 2. 用轻木设计一座跨距600 mm的桥梁结构，能承受15 kg中心载荷且安全系数为2。
- Achieve a mass ≤ 180 g while maintaining structural integrity. 在保持结构完整性的前提下质量≤180 g。
- Analyse failure modes using finite element software and validate with physical testing. 使用有限元软件分析失效模式并用实物测试验证。
5. Research & Theory: Showing Your Foundation | 理论与研究：展示你的基础
This section proves you are not just guessing. Discuss governing equations, relevant standards, and existing solutions. For an electronic project, explain Ohm's law, Kirchhoff's rules, and component selection criteria. For structures, outline Young's modulus, bending moments, and buckling theory. Always cite your sources using a recognised style (Harvard or IEEE). The theory must then be explicitly applied later in your calculations.
这一部分证明你不是凭空猜测。讨论控制方程、相关标准和已有解决方案。对于电子项目，解释欧姆定律、基尔霍夫定律和元件选型标准。对于结构项目，概述杨氏模量、弯矩和屈曲理论。始终使用公认的格式（哈佛或IEEE）引用来源。这些理论必须在后续计算中明确应用。
Use diagrams liberally. A free-body diagram with labelled forces, or a circuit schematic, earns strong Presentation marks. Ensure every figure is numbered and captioned, e.g., "Figure 2: Forces acting on the cantilever beam".
大量使用图示。带标注的受力图或电路原理图能获取高额呈现分。确保每张图有编号和标题，例如“图2：悬臂梁受力分析”。
6. Design, Analysis & Methods: Your Engineering Process | 设计、分析和方法：你的工程流程
Here you describe the step-by-step evolution of your solution. Include concept sketches, decision matrices, and iterations. Show how you moved from a vague idea to a refined design. A decision matrix (weighted or unweighted) comparing 3–4 concepts against key criteria demonstrates systematic selection and directly earns Analysis marks.
在此描述你的解决方案如何一步步演进。包含概念草图、决策矩阵和迭代过程。展示如何从模糊想法变为精化设计。一个比较3–4种概念与关键标准的决策矩阵（加权或非加权）能够体现系统选择，直接赚取分析分。
Present your calculations clearly. Use the following format for every key equation:
σ = F / A = 150 N / (2 × 10⁻³ m²) = 75 000 Pa = 75 kPa
State the formula, substitute values, give the result with the correct unit and correct significant figures. Never skip steps. This is where many candidates lose marks by hiding their working in an appendix.
清楚展示计算过程。每个关键公式采用如下格式：列出公式，代入数值，给出带正确单位和有效数字的结果。勿跳过步骤。许多考生因将计算过程藏在附录中而失分。
For manufacturing, detail materials, processes (laser cutting, 3D printing, soldering), and quality checks. Photographs of jigs, setups, and intermediate prototypes strengthen authenticity.
在制造部分，详细说明材料、工艺（激光切割、3D打印、焊接）和质量检查。夹具、装置和中间样机的照片可增强真实性。
7. Results: Just the Facts | 结果：只呈现事实
Present your measured data neutrally, without opinion. Use tables for raw data and graphs for trends. Every table and graph must be labelled, with units in column headings or axis labels. If you took multiple readings, include mean, range, and percentage uncertainty. Common SQA praise goes to candidates who calculate uncertainty and discuss it later in the evaluation.
中立地呈现测量数据，不加个人观点。用表格展示原始数据，用图表展示趋势。每个表格和图表必须标注，在列标题或坐标轴标签中注明单位。如果进行了多次测量，应包含平均值、极差和百分比不确定度。SQA 通常赞赏那些计算不确定度并在后续评价中讨论的考生。
Example table structure:
表格结构示例：
| Load (N) | Deflection Trial 1 (mm) | Trial 2 (mm) | Trial 3 (mm) | Mean (mm) | ± Unc. (mm) |
| 5.0 | 1.2 | 1.3 | 1.3 | 1.27 | 0.05 |
If your project involves electronics, include oscilloscope screenshots or multimeter readings. For structures, show before/after photos of failure. The visual evidence is powerful.
如果项目涉及电子学，应包含示波器截图或万用表读数。对于结构，展示失效前后的照片。视觉证据非常有力。
8. Discussion & Evaluation: The Heart of Your Report | 讨论与评估：报告的核心
This is where over one-third of marks are decided. Do not merely repeat results. Interpret them. Compare measured values with theoretical predictions and calculate percentage error. For instance: "The experimental beam deflection was 3.8 mm, versus a theoretical value of 3.5 mm, an error of 8.6%. This discrepancy is likely due to the assumption of perfectly rigid supports, whereas the clamps allowed a slight rotation of 0.5°."
这是决定三分之一以上分数的部分。不要简单重复结果。要解读它们。比较测量值与理论预测值，计算百分比误差。例如：“实验测得的梁挠度为3.8 mm，而理论值为3.5 mm，误差为8.6%。这一差异很可能源于假设支撑为完全刚性，而夹具允许约0.5°的微小转动。”
Critically assess every objective. Did you meet the specification? If not, by how much, and why? This demonstrates maturity. Discuss sources of error: systematic (instrument calibration), random (human reaction time), and environmental (temperature drift). For each error, suggest a concrete improvement – not just 'use better equipment', but 'use a digital dial gauge with 0.01 mm resolution instead of the manual ruler to reduce parallax error'.
批判性地评估每一个目标。你是否满足规范？如果没有，差距多大，为什么？这体现了成熟的思维。讨论误差来源：系统误差（仪器校准）、随机误差（人为反应时间）和环境误差（温度漂移）。针对每个误差，提出具体的改进建议——不仅仅是“使用更好的设备”，而是“使用分辨率为0.01 mm的数字千分表替代手动直尺，以减少视差误差”。
Link back to your literature review and explain any anomalies using the theory you researched. This closed-loop reasoning is a hallmark of Advanced Higher level thinking.
回扣文献综述，用你研究过的理论解释任何异常。这种闭环推理是高级高阶思维能力的标志。
9. Conclusions: No New Information | 结论：不引入新信息
Restate the main findings as direct answers to your original objectives. Use bullet points or a short numbered list. Keep it factual, brief, and powerful. Avoid phrases like 'I learned a lot'. Instead write: "The optimised wind turbine achieved a peak power of 2.4 W at 12° pitch, meeting the power objective of >2.0 W but not the secondary target of 5.0 W. The structure withstood the 15 kg proof load without failure, confirming a safety factor above the specified 2."
用直接回答原始目标的方式重述主要发现。可使用要点或简短编号列表。保持事实性、简洁有力。避免使用“我学到很多”一类表述，而应写：“优化后的风力涡轮机在12°桨距时达到峰值功率2.4 W，满足>2.0 W的功率目标，但未达成5.0 W的次要目标。结构在15 kg验证载荷下未失效，证实安全系数高于指定的2。”
If appropriate, suggest one line of future work, but only if it naturally extends your conclusion.
如果合适，可提一句未来工作，但仅限于自然延伸结论的情况。
10. References & Appendices: The Backstage | 参考文献与附录：幕后
Use a standard referencing system (Harvard: author-date; or IEEE: numbered). Include textbooks, datasheets, websites with access dates, and software tools. Every in-text citation must have a matching reference, and vice versa. Poor referencing can drag a brilliant report down to a lower band.
使用标准参考文献体系（哈佛：作者-日期；或IEEE：数字编号）。包含教科书、数据手册、带访问日期的网站以及软件工具。每个文内引用必须有对应的参考文献条目，反之亦然。糟糕的引用会拉低一份出色报告的评分等级。
Appendices should contain only supplementary material: full data sets, manufacturing drawings, large code blocks, risk assessments. Do not place any content essential to the main argument here, as examiners may not read appendices thoroughly. Label them Appendix A, B, C, and refer to them in the text.
附录只应包含补充性材料：完整数据集、加工图纸、大段代码、风险评估。不要将任何对核心论证至关重要的内容放在此处，因为考官可能不会仔细阅读附录。用附录A、B、C标注，并在正文中引用。
11. Common Pitfalls and How to Avoid Them | 常见陷阱及规避方法
Many Year 13 students lose marks for avoidable reasons. Here are the top five mistakes and straightforward fixes.
许多13年级学生因可避免的原因而失分。以下是五大错误及直接解决方法。
| Pitfall | Fix |
| No clear objectives | Number a list of 3–5 SMART objectives in the introduction. |
| Missing units / wrong significant figures | Triple-check all values; align with measuring instrument resolution. |
| Discussion is only descriptive | Force yourself to add a 'why' after every statement; compare to theory. |
| Graphs without titles or axis labels | Create a checklist: title, x-axis (unit), y-axis (unit), legend if needed. |
| Weak evaluation: 'went well overall' | Quantify success against each objective with a percentage or metric. |
12. Annotated Sample: Signal Amplifier Project Excerpt | 带注释范文：信号放大器项目节选
Below is a short excerpt from a top-scoring report on a transistor amplifier design. Notice how theory, calculation, and critical evaluation intertwine. (Candidate annotations are in italics.)
以下是一份高分晶体管放大器设计报告的简短节选。注意理论、计算与批判性评价如何交织。（考生自注以斜体标示。）
[Excerpt from Section 4: Analysis]
[节选自第4节：分析]
The required voltage gain AV fied as 15 ± 2. For a common-emitter amplifier, the small-signal gain is approximated by AV ≈ -RC / re, where re = 26 mV / IC. Selecting a quiescent collector current IC of 2 mA gave re = 13 Ω. Therefore, RC needed to be approx 195 Ω. The nearest E24 resistor is 180 Ω, which would yield a gain of 13.8, slightly below specification. To compensate, a bypass capacitor CE across the emitter resistor for AC signals was added to reduce the effective emitter resistance, boosting gain to 16.5. (I demonstrated theoretical understanding and justified component choice – Analysis marks.)
要求电压增益 AV 规格为 15 ± 2。对于共射放大器，小信号增益近似为 AV ≈ -RC / re，其中 re = 26 mV / IC。选择静态集电极电流 IC 为 2 mA，得 re = 13 Ω。因此，RC 需约 195 Ω。最接近的 E24 电阻为 180 Ω，将产生增益 13.8，略低于规格。为此添加发射极电阻旁路电容 CE 处理交流信号，降低有效发射极电阻，将增益提升至 16.5。（展示理论理解并论证元件选择——分析分。）
ation from the predicted 16.5 can be attributed to the tolerance of the 180 Ω resistor (±5% was neglected in the simple model. (I explained discrepancy with a genuine physical reason – Evaluation marks.)
在 1 kHz 下实验测得增益为 15.9，在容差范围内。与预测值 16.5 的 0.6 偏差可归因于 180 Ω 电阻的容差（±5%）以及简单模型中忽略的厄利效应。（用真实物理原因解释偏差——评价分。）
This passage exemplifies the tight integration of calculation, practical measurement, and critical reflection that typifies an A-grade SQA report.
这段文字示范了计算、实际测量与批判性反思紧密结合的特点，这是 A 等 SQA 报告的典型风格。
