排出
How to Understand
排出 means 'to exhaust' or 'to expel' in English, typically referring to the removal of something from a system, such as air, liquid, or waste. It is often used in contexts involving machinery, biology, or environmental processes.
The character 排 (pái) originally meant 'to arrange' or 'to line up,' and it later developed the meaning of 'to push out' or 'to expel.' 出 (chū) means 'to go out' or 'to emerge.' Together, they form a compound that conveys the idea of pushing something out of a space or system.
排出 is commonly used in technical, medical, or industrial contexts. For example, it can describe the expulsion of air from a container or the removal of waste from a body. Understanding this term helps learners grasp how Chinese expresses mechanical or biological processes of elimination.
