Understanding 功率 (Power)
功率 (gōnglǜ) refers to the rate at which work is done or energy is transferred, commonly used in physics and engineering contexts. It is often measured in watts (瓦特), indicating how much energy is converted per unit time.
Common Usage
This term is frequently used when discussing electrical devices, engines, or machines to describe their output capacity. For example, a motor's 功率 tells you how powerful it is.
Collocations and Patterns
- 功率大小 (gōnglǜ dàxiǎo): size or magnitude of power, used to compare devices.
- 功率输出 (gōnglǜ shūchū): power output, common in technical descriptions.
- 提高功率 (tígāo gōnglǜ): increase power, often used when optimizing performance.
Usage Notes
功率 is a technical term and is not used for abstract or metaphorical 'power.' It specifically relates to physical work or energy transfer rates. Avoid confusing it with 能量 (energy) or 力量 (strength), which have different meanings.
When using 功率, it usually appears with units like 瓦 (watt) or 千瓦 (kilowatt) and is often paired with verbs like 提高 (increase) or 测量 (measure).
