密封性能
这种容器的密封性能经过严格测试，能够承受高压环境。
The sealing performance of this container has been rigorously tested and can withstand high-pressure environments.
The ability of a material, container, or system to prevent leakage of gases, liquids, or contaminants.
密封性能是评估密封件质量的关键指标之一。
Sealing performance is one of the key indicators for evaluating the quality of sealing components.
汽车发动机的密封性能直接影响其燃油效率和排放标准。
The sealing performance of an automobile engine directly affects its fuel efficiency and emission standards.
Often used in mechanical engineering, automotive design, and industrial manufacturing contexts.
Pro Tip
Technical Context Tip
When discussing 密封性能 in engineering, pair it with terms like '耐压性' (pressure resistance), '耐腐蚀性' (corrosion resistance), or '耐高温性' (high-temperature resistance' to provide a comprehensive evaluation.
Gold Rule
Precision in Translation
In English, 'sealing performance' is the most accurate translation. Avoid generic terms like 'seal quality' unless referring to a specific metric.
Word Origin
密封 (mìfēng) = 'seal/airtight' + 性能 (xìngnéng) = 'performance'. The compound emerged in modern technical Chinese to describe the functional quality of sealing mechanisms.
Usage Notes
Primarily used in technical and engineering contexts. Avoid using in casual conversation unless discussing technical specifications.
