Paper 2 and Paper 5 contain questions drawn from all syllabus topics, requiring candidates to demonstrate analytical and problem-solving abilities. The coursework (Papers 3 and 6) involves an individual project that is internally assessed and externally moderated, focusing on the design and realisation of an engineering solution.

试卷二和试卷五包含来自所有大纲主题的题目，要求考生展示分析与解决问题的能力。课程作业(试卷三和六)涉及内部评估、外部审核的个人项目，重点在于工程解决方案的设计和实现。

3. Engineering Principles and Core Concepts | 工程原理与核心概念

This foundational section covers the scientific laws and engineering fundamentals that underpin the entire course. Topics include systems of measurement, SI units, force, mass, work, energy, and power. Learners also study moments, couples, and the conditions for static equilibrium. These concepts appear repeatedly in more advanced topics, so mastery early on is essential.

基础部分涵盖科学定律和贯穿整个课程的工程基础。内容包括测量体系、国际单位制、力、质量、功、能量和功率。学生还将学习力矩、力偶以及静力平衡条件。这些概念会在后续高阶主题中反复出现，因此早期掌握至关重要。

4. Materials Science and Selection | 材料科学与选材

Engineers must understand the properties, behaviour, and failure modes of materials. The syllabus explores ferrous and non-ferrous metals, polymers, ceramics, and composites. Key mechanical properties such as tensile strength, hardness, toughness, and ductility are defined and tested through standard tests. Material selection charts and life-cycle considerations are also covered.

工程师必须理解材料的性质、行为与失效模式。大纲涵盖黑色与有色金属、聚合物、陶瓷和复合材料。拉伸强度、硬度、韧性和延展性等关键机械性能通过标准试验来定义和测试。材料选择图表和生命周期考量也包含在内。

σ = F / A

Here, σ represents stress (Pa), F is the applied force (N), and A is the cross-sectional area (m²). Understanding stress-strain curves and Young’s modulus E = σ / ε is fundamental to material selection.

在这里，σ 表示应力(Pa)，F 是施加的力(N)，A 是横截面积(m²)。理解应力-应变曲线及杨氏模量 E = σ / ε 对材料选择至关重要。

5. Manufacturing Processes and Technology | 制造工艺与技术

This part of the syllabus examines traditional and modern manufacturing techniques. Casting, forging, rolling, extrusion, and machining are covered alongside advanced processes such as additive manufacturing (3D printing). Students learn to select appropriate manufacturing methods based on material, product geometry, batch size, and cost. Quality control, metrology, and the use of CNC machines are also key topics.

6. Mechanical Systems and Machine Elements | 机械系统与机械元件

Mechanical systems form the backbone of many engineered products. The syllabus delves into mechanisms such as gears, belts, chains, linkages, and cams. Velocity ratio, mechanical advantage, and efficiency calculations are essential. Bearings, seals, clutches, and brakes are also studied in the context of transmitting and controlling motion.

机械系统是许多工程产品的支柱。大纲深入研究齿轮、皮带、链条、连杆和凸轮等机构。速度比、机械增益和效率计算是核心内容。轴承、密封件、离合器和制动器也在传递和控制运动的背景下学习。

Mechanical Advantage = Load / Effort

For a simple gear train, the velocity ratio is the product of the driven teeth divided by the driver teeth. These relationships allow engineers to design systems that amplify forces or increase speed.

对于简单齿轮系，速度比等于从动轮齿数之积除以主动轮齿数之积。这些关系使工程师能够设计出增大力或提高速度的系统。

7. Electrical and Electronic Systems | 电气与电子系统

Modern engineering requires a thorough grasp of electrical principles. Topics include Ohm’s law, Kirchhoff’s laws, power and energy in DC circuits, and the behaviour of resistors, capacitors, and inductors. The syllabus also introduces semiconductors, diodes, transistors, and operational amplifiers. Learners apply these concepts to simple sensing, switching, and amplification circuits.

现代工程要求彻底掌握电气原理。主题包括欧姆定律、基尔霍夫定律、直流电路中的功率与能量，以及电阻、电容和电感的行为。大纲还介绍了半导体、二极管、晶体管和运算放大器。学生将这些概念应用于简单的传感、开关和放大电路。

V = I × R

Engineering applications often use potential divider circuits for sensors. The output voltage Vout in a voltage divider is Vout = Vin × (R2 / (R1 + R2)). Knowledge of Boolean logic and combinational circuits is also developed.

工程应用中常使用分压电路作为传感器。分压器输出电压 Vout = Vin × (R2 / (R1 + R2))。布尔逻辑和组合电路的知识也会得到培养。

8. Structures and Fluid Mechanics | 结构与流体力学

Structural analysis introduces concepts such as bending moments, shear forces, and deflection in beams. Students calculate reactions, draw shear force and bending moment diagrams for simply supported and cantilever beams. In fluid mechanics, hydrostatic pressure, Archimedes’ principle, and Bernoulli’s equation are studied. The continuity equation and its application to pipe flow are also covered.

结构分析引入弯矩、剪力和梁的挠度等概念。学生计算支反力，绘制简支梁和悬臂梁的剪力图与弯矩图。在流体力学中，学习静水压力、阿基米德原理和伯努利方程。连续性方程及其在管道流中的应用也有涉及。

p = ρ g h

Hydrostatic pressure p depends on fluid density ρ, gravitational acceleration g, and depth h. Bernoulli’s principle relates pressure, velocity, and elevation in a flowing fluid, enabling designs like venturi meters and airfoils.

静水压力 p 取决于流体密度 ρ、重力加速度 g 和深度 h。伯努利原理关联了流动流体中的压力、速度和高度，可用于文丘里管和翼型等设计。

9. Design, Communication and Project Management | 设计、沟通与项目管理

The engineering design process is central to the coursework and to many exam questions. Learners are taught to interpret and create engineering drawings, including orthographic projections, isometric views, and circuit diagrams. The use of CAD software is encouraged. Project management tools such as Gantt charts and critical path analysis help in planning and executing a design project successfully.

10. Mathematics for Engineers | 工程数学

A strong mathematical toolkit underpins every engineering discipline. The syllabus explicitly requires competence in algebra, trigonometry, vectors, calculus (differentiation and integration), and statistics. Common applications include calculating rates of change (e.g., velocity and acceleration), areas under graphs (e.g., work done by a variable force), and statistical process control. Formulas are tested in context rather than as abstract math.

强大的数学工具包支撑着每个工程学科。大纲明确要求掌握代数、三角学、向量、微积分(微分和积分)以及统计学。常见应用包括计算变化率(如速度和加速度)、图形下面积(如变力做功)以及统计过程控制。公式在工程语境中考查，而非抽象数学。

∫ F dx = ΔW

Integration of a force-displacement graph yields the work done. Similarly, differentiation of displacement gives velocity, and differentiation of velocity gives acceleration.

力-位移图的积分得出做功。同理，位移的微分得到速度，速度的微分得到加速度。

11. Practical Skills and Coursework Execution | 实践技能与课程作业执行

Hands-on experience is indispensable. The coursework component requires students to identify a genuine need, generate a specification, develop possible solutions, and produce a working prototype. Throughout this process, they must document all stages, apply theoretical knowledge, and reflect on testing and evaluation. Safety in the workshop, proper use of tools, and risk assessments are also assessed.

动手经验不可或缺。课程作业要求学生识别真实需求、制定规格说明、开发可能的解决方案并制作工作原型。在此过程中，他们必须记录所有阶段，应用理论知识，并对测试和评估进行反思。车间的安全、工具的正确使用以及风险评估也会受到考核。

12. Revision and Examination Strategies | 复习与备考策略

Success in CAIE Engineering demands more than memorising facts. Focus on understanding the principles and being able to apply them to unfamiliar scenarios. Practise past papers under timed conditions, carefully review mark schemes to learn how examiners allocate points for problem-solving steps, and maintain a well-organised formula sheet. For coursework, keep a thorough logbook and consistently link your practical work to the theoretical syllabus.

在 CAIE 工程课中取得成功需要的不仅仅是记忆事实。要注重理解原理，并能够将其应用于陌生场景。在限时条件下练习历年真题，仔细研读评分方案以了解考官如何对问题解决步骤分配分数，并保持一份条理清晰的公式表。对于课程作业，要保持详尽的日志，并始终将实践工作与理论大纲联系起来。
