功率
How to Understand
功率 refers to the rate at which work is done or energy is transferred, commonly used in physics and engineering contexts. It is a measure of how quickly energy is being used or produced, often expressed in watts (W).
The character 功 (gōng) means 'work' or 'effort,' while 率 (lǜ) means 'rate' or 'ratio.' Together, they form a term that describes the efficiency or speed of energy use, making it essential in discussions about machines, electricity, and performance.
功率 is widely used in technical fields such as mechanical engineering, electronics, and automotive industries. In daily life, it may appear on appliance labels, indicating how much power they consume. Understanding 功率 helps in choosing energy-efficient devices and evaluating the performance of machinery.
