1. Introduction: Why Do Excellent C++ Developers Rely on Namespaces? Have you ever experienced a moment of despair: after writing hundreds of lines of code, suddenly encountering an “identifier redefinition” error after integrating a third-party library? Your own defined print() function works perfectly, but after introducing a logging library, you find yourself in a naming … Read more
1. Introduction: Why Do We Need “Modules”? When you first start learning Python, you typically write a few lines of code in a single file, such as printing “Hello World” or performing simple mathematical calculations. This is akin to jotting down notes on a sticky note, quick and easy. However, as you learn more and … Read more
If you have learned Python to a certain extent, you must have come across the following piece of code: @log def hello(): print("Hello World") When you first see <span>@log</span>, many people have the same feeling: —— This looks advanced, but I have no idea what it does. Some people get stuck; some memorize it; and … Read more
In the world of programming, the biggest difference between beginners and experts often lies not in how many algorithms they know, but in how they organize their code. Have you ever experienced a situation where, to implement a repetitive function, you keep usingCtrl+C and Ctrl+V, only to find that the main function has become long … Read more

Currently, as global climate change issues become increasingly severe, including glacier melting and species extinction caused by global warming, the primary reason for these problems is carbon emissions. The resolution of these environmental issues is urgent, thus many countries around the world have proposed their respective carbon peak and carbon neutrality goals, known as the … Read more
This article analyzes the strategic significance of third-generation semiconductors and discusses the development status of China’s technology and industrial capacity in related fields. It explains that “large size and cost reduction” are the current focus of silicon carbide (SiC) and gallium nitride (GaN) technology development, and explores the development models of third-generation semiconductor companies as … Read more
This article analyzes the strategic significance of third-generation semiconductors and discusses the development status of China’s technology and industrialization capabilities in related fields. It elaborates that “large size and cost reduction” is the current focus of development for silicon carbide (SiC) and gallium nitride (GaN) technologies, and explores the development models of enterprises in the … Read more
Source: Content from “CITIC Securities Xu Tao, Hu Ye Qian Wen, and Yan Lei”, thank you. Wafers (wafer) are the fundamental raw materials for manufacturing semiconductor devices. Extremely high-purity semiconductors are prepared into wafers through processes such as crystal pulling and slicing. Wafers undergo a series of semiconductor manufacturing processes to form extremely small circuit … Read more
1 Background SiC/GaN is increasingly being applied in designs with higher power and voltage, such as motor drivers for electric vehicles (EVs), fast charging stations for electric vehicles, onboard and offboard chargers, wind and solar inverters, and industrial control power supplies/lighting power supplies. As the switching speed of SiC/GaN power devices increases (extremely high dv/dt), … Read more
