Understanding 性能
The word 性能 (xìngnéng) refers primarily to the functional capabilities or performance of machines, devices, software, or systems. It is commonly used in technical and everyday contexts to describe how well something works or behaves under certain conditions.
Usage Notes
性能 is often paired with specific objects like 手机 (phone), 汽车 (car), or 软件 (software) to discuss their operational quality or efficiency. It emphasizes measurable or observable qualities such as speed, fuel efficiency, or optimization.
Common Collocations
- 性能好 / 性能强: good or strong performance, used to praise a product.
- 性能优化: performance optimization, often in software or systems.
- 燃油性能: fuel performance, related to cars.
Nuances
When using 性能, speakers imply a focus on practical, technical aspects rather than abstract qualities. It is more formal and technical than simply saying 功能 (function), which can be broader. Avoid confusing 性能 with 性格 (personality) despite sharing 性.
Summary
Use 性能 when discussing how well something functions or performs, especially in technical or product-related conversations. It helps convey precise information about capability and efficiency.
