Usage of 定时
The word 定时 (dìngshí) means to set or fix a specific time for something to happen. It is commonly used when referring to scheduled or timed actions, such as machines turning on/off, regular checks, or medication schedules.
Common Collocations
- 定时开关 (dìngshí kāiguān): timed switch, used for devices that operate automatically at set times.
- 定时检查 (dìngshí jiǎnchá): regular inspection, often used in work or safety contexts.
- 定时服药 (dìngshí fúyào): taking medicine on schedule, important in health contexts.
Notes
When using 定时, the emphasis is on the action happening at a fixed or regular time. It often implies reliability and routine. Avoid confusing 定时 with 及时 (jíshí), which means 'in time' or 'promptly' and focuses on timeliness rather than scheduling.
This word is formal and commonly used in both spoken and written Chinese, especially in technical, medical, and professional settings.
