调节

The Chinese word 调节 (tiáojié) is composed of two characters: 调 (tiáo) and 节 (jié). The character 调 originally meant "to tune" or "to harmonize", and it is often used in the context of music or other arts. The character 节 originally meant "a joint" or "a segment", and it is often used in the context of time or space. When these two characters are combined, they form the word 调节, which means "to regulate" or "to adjust". This word is often used in the context of controlling or managing something, such as temperature, speed, or volume. For example, you might use the word 调节 to describe the process of adjusting the temperature of a room or the speed of a car.
