• Summary: 调试 (tiáoshì) is a fundamental Chinese verb that means “to debug,” “to tune,” or “to adjust.” Primarily used in technical contexts like software development and engineering, it describes the systematic process of adjusting and testing a program, machine, or instrument to make it work correctly and optimally. Understanding 调试 is essential for anyone involved in technology, engineering, or even music in a Mandarin-speaking environment.

• Pinyin (with tone marks): tiáoshì
• Part of Speech: Verb
• HSK Level: HSK 5
• Concise Definition: To adjust and test a machine, piece of equipment, or computer program to make it work correctly.
• In a Nutshell: Think of 调试 as the process of “fine-tuning.” While its most common translation is “to debug” in the world of software, its meaning is broader. It applies to any situation where you make small changes and run tests to fix a problem or improve performance. Whether it's a programmer hunting for a bug in their code, an engineer calibrating a new machine, or a musician tuning a guitar, they are all performing 调试. It's an active, problem-solving word that implies a cycle of adjusting and checking.

• 调 (tiáo): This character means “to adjust,” “to regulate,” or “to tune.” It evokes the idea of making modifications to achieve a specific state, like adjusting the volume (调音量) or tuning a radio station (调频).
• 试 (shì): This character means “to test” or “to try.” It's the same character used in words like “exam” (考试 kǎoshì) and “to try on clothes” (试穿 shìchuān). It signifies an action taken to check for a result or verify correctness.

When combined, 调 (adjust) + 试 (test) literally create the meaning “adjust and test.” This beautifully captures the iterative nature of debugging and tuning: you make a change (调), you check the result (试), and you repeat the cycle until the system performs perfectly.

While 调试 isn't a term rooted in ancient Chinese philosophy, its widespread use reflects the cultural and economic landscape of modern China. With the country's transformation into a global technology and manufacturing powerhouse, 调试 has become a high-frequency word in business, education, and daily urban life. It represents the values of precision, problem-solving, and continuous improvement that are central to modern engineering and development culture. A subtle but interesting comparison can be made with the English term “debug.” The English word originates from a literal story of a moth causing a computer malfunction—a “bug” in the machine. It focuses on the problem (the bug). The Chinese term 调试, meaning “adjust-test,” focuses on the process used to solve the problem. This reflects a practical, process-oriented mindset: identify an issue, methodically adjust, and systematically test until a solution is found. It's less about a single “bug” and more about bringing a complex system into a state of correct, harmonious operation.

调试 is a neutral, technical term used in formal and informal professional settings.

• In Software and IT: This is the most common context. Programmers (程序员 chéngxùyuán) spend a significant amount of time doing 调试 to fix errors in their code.
• In Engineering and Manufacturing: Engineers (工程师 gōngchéngshī) must 调试 new equipment, calibrate instruments, or tune machinery on an assembly line to ensure it functions correctly and efficiently.
• In Music and Audio/Visual: A musician will 调试 their instrument (e.g., a guitar or piano) to ensure it's in tune. A sound technician will 调试 the microphones and speakers before a performance.
• As a “Phase” or “Stage”: It is often used to describe a specific period in a project's lifecycle, such as the “调试阶段” (tiáoshì jiēduàn) or “debugging phase.”

A common pitfall for learners is confusing 调试 with similar-sounding words like 调整 (tiáozhěng) and 修理 (xiūlǐ).

• 调试 (tiáoshì) vs. 调整 (tiáozhěng):
  • 调试 (tiáoshì) implies a “test” (试) component. It's a problem-solving process to make something work correctly.
  • 调整 (tiáozhěng) is a more general “adjustment.” You adjust things that aren't necessarily “broken” but need to be changed. It doesn't inherently involve a testing cycle.
  • Example: You 调试 a software program (find and fix bugs), but you 调整 your work schedule (change the times).
  • Incorrect: 我要调试我的计划。(Wǒ yào tiáoshì wǒ de jìhuà.) → I need to debug my plan. (Sounds strange).
  • Correct: 我要调整我的计划。(Wǒ yào tiáozhěng wǒ de jìhuà.) → I need to adjust my plan.
• 调试 (tiáoshì) vs. 修理 (xiūlǐ):
  • 调试 (tiáoshì) is for fixing performance, logic, or configuration issues. The item is often functional but not working correctly.
  • 修理 (xiūlǐ) means “to repair” something that is physically broken or completely non-functional.
  • Example: You 修理 a shattered phone screen, but you 调试 the phone's software if an app keeps crashing.
  • Incorrect: 我的自行车车胎爆了，我需要调试一下。(Wǒ de zìxíngchē chētāi bàole, wǒ xūyào tiáoshì yíxià.) → My bike tire popped, I need to debug it. (Logically incorrect).
  • Correct: 我的自行车车胎爆了，我需要修理一下。(Wǒ de zìxíngchē chētāi bàole, wǒ xūyào xiūlǐ yíxià.) → My bike tire popped, I need to repair it.

• 调整 (tiáozhěng) - To adjust, to regulate. A broader term for making changes, not necessarily involving a test-and-fix cycle.
• 修理 (xiūlǐ) - To repair, to fix. Used for something that is physically broken.
• 测试 (cèshì) - To test. This is the “test” component of 调试, and a key activity during the debugging process.
• 校准 (jiàozhǔn) - To calibrate. A very specific and precise type of 调试, used for measurement instruments.
• 改进 (gǎijìn) - To improve, to make better. Broader than debugging; focuses on enhancement rather than just fixing errors.
• 故障 (gùzhàng) - Fault, malfunction, glitch. This is the reason you need to 调试. Often used interchangeably with the English loanword “bug”.
• 程序 (chéngxù) - Program, software. The most common thing that gets “debugged.”
• 系统 (xìtǒng) - System. Another common object of 调试, such as a computer system or operating system.
• 工程师 (gōngchéngshī) - Engineer. The professional who often performs the act of 调试.
