====== gōnglǜ: 功率 - Power (Scientific/Technical) ====== ===== Quick Summary ===== * **Keywords:** 功率, gonglu, Chinese word for power, engine power in Chinese, electrical power Chinese, what is gonglu, watts in Chinese, horsepower in Chinese, technical Chinese, 功, 率 * **Summary:** 功率 (gōnglǜ) is the essential Chinese term for "power" in a scientific or technical context, referring to the rate at which work is done or energy is used. Whether you're discussing the horsepower of a car engine, the wattage of a microwave, or the output of a solar panel, 功率 is the specific and correct word. This page explores its meaning, character origins, and practical use in modern China's tech-driven society, helping you avoid common mistakes like confusing it with political power or physical strength. ===== Core Meaning ===== 功率 * **Pinyin (with tone marks):** gōng lǜ * **Part of Speech:** Noun * **HSK Level:** HSK 6 * **Concise Definition:** Power, specifically the rate of energy transfer or the rate at which work is done (e.g., watts, horsepower). * **In a Nutshell:** Forget about political power or personal strength. 功率 (gōnglǜ) is the "power" you learned about in physics class. It measures how *fast* a machine can work or use energy. A high-power (大功率) air conditioner cools a room quickly, and a high-power charger juices up your phone faster. It's a technical term that you'll frequently encounter on appliance labels, car specifications, and in any discussion about technology or machinery. ===== Character Breakdown ===== * **功 (gōng):** This character is all about "work," "achievement," or "merit." Think of功夫 (gōngfu), which means skill acquired through hard work. In physics, 功 refers specifically to "work" in the sense of force applied over a distance. * **率 (lǜ):** This character means "rate," "ratio," or "frequency." You see it in words like 效率 (xiàolǜ - efficiency) and 频率 (pínlǜ - frequency). It describes how often or how fast something happens relative to another measure (like time). * **How they combine:** The combination is perfectly logical and descriptive. 功 (work) + 率 (rate) literally translates to "work rate," which is the exact scientific definition of power. This is a great example of how modern Chinese creates precise technical terms from classical characters. ===== Cultural Context and Significance ===== While 功率 (gōnglǜ) doesn't have deep roots in ancient Chinese philosophy, its widespread use is incredibly significant in understanding **Modern China**. The term embodies the country's focus on industrialization, technological development, and manufacturing. The obsession with metrics like engine power, charging speed, and energy efficiency is a cultural phenomenon reflecting a national drive towards progress and innovation. A key cultural contrast is with the English word "power." In English, "power" is a broad, ambiguous term that can mean political influence, physical strength, or electrical power. A beginner might mistakenly use 功率 to talk about a powerful person. Chinese, however, is far more specific: * **功率 (gōnglǜ):** Scientific/technical power (watts, horsepower). * **权力 (quánlì):** Political power, authority. * **力量 (lìliàng):** Physical strength, force. This linguistic precision reflects a clear compartmentalization of concepts. For a learner, understanding this distinction is crucial. Using 功率 correctly shows not just vocabulary knowledge, but an understanding of a modern, scientific worldview embedded within the language. ===== Practical Usage in Modern China ===== You'll see and hear 功率 in many everyday situations, especially when dealing with technology, vehicles, or home appliances. * **Shopping for Electronics:** When buying a microwave, air conditioner, or hairdryer, the product specifications will always list its 功率, usually in watts (瓦 wǎ). "大功率" (dà gōnglǜ, high-power) is a common marketing term for devices that work faster and more intensely. * **Discussing Cars:** Car enthusiasts will frequently discuss a car's 发动机功率 (fādòngjī gōnglǜ - engine power), measured in kilowatts (千瓦 qiānwǎ) or horsepower (马力 mǎlì). * **Energy Consumption:** A device with a high 功率 will consume more electricity. You might hear someone say, "这个取暖器功率太大了,很耗电" (This heater's power is too high, it uses a lot of electricity). * **Common Collocations:** * **额定功率 (édìng gōnglǜ):** Rated power (the standard operating power). * **输出功率 (shūchū gōnglǜ):** Output power. * **峰值功率 (fēngzhí gōnglǜ):** Peak power. ===== Example Sentences ===== * **Example 1:** * 这台空调的**功率**太小了,房间半天都凉不下来。 * Pinyin: Zhè tái kōngtiáo de **gōnglǜ** tài xiǎo le, fángjiān bàntiān dōu liáng bù xiàlái. * English: This air conditioner's power is too low; the room takes forever to cool down. * Analysis: A very common real-life complaint.

Bābǎi wǎ de gòu yòng le ma? * English: What power microwave do you want to buy? Is 800 watts enough? * Analysis: A typical question when shopping for appliances. It shows how 功率 is quantified with units like 瓦 (wǎ - watt). * **Example 4:** * 手机充电器的**功率**越大,充电速度通常也越快。 * Pinyin: Shǒujī chōngdiànqì de **gōnglǜ** yuè dà, chōngdiàn sùdù tōngcháng yě yuè kuài. * English: The higher the power of a phone charger, the faster the charging speed usually is. * Analysis: This connects 功率 directly to the user benefit of "speed," a key selling point for modern electronics. * **Example 5:** * 购买电器时,一定要查看它的额定**功率**和能效等级。 * Pinyin: Gòumǎi diànqì shí, yīdìng yào chákàn tā de édìng **gōnglǜ** hé néngxiào děngjí. * English: When purchasing electrical appliances, you must check their rated power and energy efficiency rating. * Analysis: This sentence introduces the formal term 额定功率 (édìng gōnglǜ - rated power), which is what you'll see printed on official labels. * **Example 6:** * 这个音响的峰值**功率**可以达到500瓦。 * Pinyin: Zhège yīnxiǎng de fēngzhí **gōnglǜ** kěyǐ dádào wǔbǎi wǎ. * English: The peak power of this audio system can reach 500 watts. * Analysis: Demonstrates another technical collocation, 峰值功率 (fēngzhí gōnglǜ - peak power), common in audio and electronics specs. * **Example 7:** * 在物理学中,**功率**的定义是单位时间内所做的功。 * Pinyin: Zài wùlǐxué zhōng, **gōnglǜ** de dìngyì shì dānwèi shíjiān nèi suǒ zuò de gōng. * English: In physics, the definition of power is the work done per unit of time. * Analysis: This is the textbook definition, showing its formal, scientific usage. * **Example 8:** * 我们需要一台大**功率**的工业风扇来给车间降温。 * Pinyin: Wǒmen xūyào yī tái dà **gōnglǜ** de gōngyè fēngshàn lái gěi chējiān jiàngwēn. * English: We need a high-power industrial fan to cool down the workshop. * Analysis: Highlights the use of "大功率" (dà gōnglǜ - high-power) as a compound adjective to describe a type of machine. * **Example 9:** * 太阳能电池板的输出**功率**取决于光照强度。 * Pinyin: Tàiyángnéng diànchíbǎn de shūchū **gōnglǜ** qǔjué yú guāngzhào qiángdù. * English: The output power of a solar panel depends on the intensity of the light. * Analysis: Shows the term used in the context of renewable energy and technology. * **Example 10:** * 为了安全,这条电路不能连接总**功率**超过2000瓦的电器。 * Pinyin: Wèile ānquán, zhè tiáo diànlù bùnéng liánjiē zǒng **gōnglǜ** chāoguò liǎngqiān wǎ de diànqì. * English: For safety, this circuit cannot be connected to appliances with a total power exceeding 2000 watts. * Analysis: A practical warning related to electrical safety, demonstrating the concept of "total power" (总功率). ===== Nuances and Common Mistakes ===== The biggest pitfall for English speakers is using 功率 for other types of "power." It is exclusively for scientific and technical power. * **Mistake:** Confusing it with political power or authority. * **Incorrect:** ~~这个总统有很多功率。~~ (Zhège zǒngtǒng yǒu hěn duō gōnglǜ.) * **Correct:** 这个总统有很大的**权力**。(Zhège zǒngtǒng yǒu hěn dà de **quánlì**.) * **Reason:** 权力 (quánlì) is for authority and political influence. 功率 is for machines. * **Mistake:** Confusing it with physical strength. * **Incorrect:** ~~那个举重运动员的功率真大。~~ (Nàge jǔzhòng yùndòngyuán de gōnglǜ zhēn dà.) * **Correct:** 那个举重运动员的**力量**真大。(Nàge jǔzhòng yùndòngyuán de **lìliàng** zhēn dà.) * **Reason:** 力量 (lìliàng) is for physical strength or force. While a weightlifter technically generates power (功率), in everyday speech you would always comment on their strength (力量). * **Mistake:** Confusing Power (rate) with Energy (amount). * **Incorrect:** ~~我家上个月用了太多功率。~~ (Wǒ jiā shàng ge yuè yòngle tài duō gōnglǜ.) * **Correct:** 我家上个月用了太多**电**。(Wǒ jiā shàng ge yuè yòngle tài duō **diàn**.) * **Reason:** You consume energy (能量) or electricity (电), which is measured in kilowatt-hours (度). 功率 is the *rate* of consumption (kilowatts). A high-power device, used over time, results in high energy consumption. ===== Related Terms and Concepts ===== * [[能量]] (néngliàng) - Energy.
