Meaning
排放 refers to the act of discharging or releasing substances, especially pollutants, gases, or waste materials into the environment. It combines 排 (to expel) and 放 (to release), and is commonly used in environmental and industrial contexts to discuss emissions from factories, vehicles, or other sources.
Usage
This word is frequently used in environmental discussions, news reports, and scientific contexts. It typically refers to the release of harmful substances like carbon dioxide, wastewater, or industrial waste. Common patterns include '排放污染物' (discharge pollutants) and '排放标准' (emission standards). It's a formal, technical term rather than everyday conversational vocabulary.
