3. Unit 2: Electronics and Control Systems | 单元二：电子与控制系统

Unit 2 forms the core of electronic theory in the course. You start with fundamental components: resistors, capacitors, diodes, transistors, and operational amplifiers, and learn to analyse circuit behaviour using Ohm’s law and Kirchhoff’s laws.

单元二是课程电子理论的核心部分。你将从基本元件入手：电阻、电容、二极管、晶体管和运算放大器，并学习运用欧姆定律和基尔霍夫定律分析电路行为。

V = I × R

欧姆定律将电压、电流和电阻的关系表示为 V = I × R。

A major emphasis is placed on microcontrollers and programming. You will write simple programs, often using flowcharts or high‑level languages such as BASIC, to read sensors (e.g. LDRs, thermistors) and control actuators (LEDs, buzzers, motors). Practical prototyping skills are central here.

微控制器和编程是一大重点。你将编写简单程序，通常使用流程图或 BASIC 等高级语言，读取传感器（如光敏电阻、热敏电阻）并控制执行器（LED、蜂鸣器、电机）。实践原型制作能力是这部分的核心。

You also study control system principles, distinguishing between open‑loop and closed‑loop systems, and understanding how feedback can improve accuracy. Components like relays and transistors are used in switching circuits, and the concept of amplification is introduced through op‑amp configurations.

你还将学习控制系统原理，区分开环和闭环系统，并理解反馈如何提升精度。继电器和晶体管等元件用于开关电路，放大概念则通过运算放大器配置引入。

4. Unit 3: Mechanisms and Structural Systems | 单元三：机械与结构系统

This unit covers the mechanical and structural principles essential to engineering. You will study forces, moments, and equilibrium, applying these concepts to real‑world structures such as beams and frames. Resolving forces and calculating support reactions are key skills.

本单元涵盖工程学中必不可少的机械与结构原理。你将学习力、力矩和平衡，并将这些概念应用于梁和框架等真实结构。力的分解和支座反力计算是关键技能。

Motion is a central topic: you distinguish between linear and rotational motion, calculate velocity ratios, and determine mechanical advantage and efficiency for machines like levers, pulleys, and gear trains. The relationship between work, power, and energy transfer is explored using equations such as W = F × d and P = W / t.

运动是本单元的核心主题：你需区分直线运动和旋转运动，计算速度比，并确定杠杆、滑轮和齿轮系等机器的机械效益与效率。功、功率与能量传递之间的关系则借助 W = F × d 和 P = W / t 等公式进行探讨。

W = F × d

恒力做的功等于力与位移的乘积。

Drive systems including belt drives, chain drives, and compound gear trains are analysed for output speed and torque. Structural analysis extends to stress, strain, and Young’s modulus, introducing the factor of safety to ensure reliable design.

带传动、链传动和复合齿轮系等传动系统也要分析输出速度和扭矩。结构分析延伸到应力、应变和杨氏模量，并引入安全系数以确保设计的可靠性。
