annuli的音標為[?"nju?l?],基本翻譯為“環,環狀物;環狀物所圍繞的區域”。
速記技巧:可以將單詞拆分記憶,如“annu(年)+ li(里)”即可。
Annuli這個詞來源于拉丁語,意為“環”。它的變化形式主要有復數形式annuli,過去式形式annul和現在分詞形式annulating。
相關單詞:
1. annul - 意為“取消,廢除”,例如“annul a contract”(取消合同)。
2. annulment - 意為“廢除,取消”,例如“the annulment of a law”(法律的廢除)。
3. annulus - 意為“環,圓環”,例如“an annulus of Saturn”(土星的環)。
4. annulled - 形容詞形式,意為“被取消的,無效的”。
5. annulli - 復數形式,在某些特定上下文中使用。
6. annulment-ing - 分詞形式,表示進行時的狀態。
7. annul-lize - 合成詞,表示“取消或廢除”。
8. annul-lify - 合成詞,表示“使無效”。
9. annul-luminous - 合成詞,表示“環形的,發光的”。
10. annul-luminously - 合成詞,表示“環狀地,發光地”。
以上這些單詞都與annuli這個詞源有關,通過不同的組合和變形,可以創造出許多與環狀、取消、廢除等相關的詞匯。

英文小作文:
Annuli are commonly found in engineering systems, such as pipelines and pumps. They play an important role in controlling flow rates, pressures, and volumes, and can significantly affect system efficiency and performance. In a pipeline system, the inner annulus is used for conveying materials, while the outer annulus acts as a buffer zone to prevent excessive pressure fluctuations. By carefully managing the annuli in various components of a system, engineers can ensure optimal performance and minimize potential issues. Understanding the role of annuli in various systems is crucial for effective troubleshooting and maintenance.
