cavitation的音標是[?k?v??te??n]，翻譯為“空化；空蝕；空穴；氣穴”。

其速記技巧為：cavity的諧音是“卡威蒂”，可以理解為空洞、空隙，所以cavitation意為空化。

Cavitation這個詞源于拉丁語，意為“空洞”或“空隙”。它的變化形式主要有復數(shù)形式cavitation和過去式cavitated。相關單詞有：

1. Cavern - 洞穴，深坑

2. Cavity - 空洞，腔室

3. Void - 空缺，空白

4. Voidness - 空無，虛空

5. Crevice - 裂隙，縫隙

6. Abyss - 深淵，深坑

7. Hollow - 空洞的，中空的

8. Voidoid - 空缺的，虛無的

9. Nebula - 星云，氣團

10. Cavernous - 洞穴般的，空洞的

Cavitation常用于描述液體在高壓下形成氣泡的現(xiàn)象，這種現(xiàn)象在蒸汽機等機械中經常出現(xiàn)。同時，它也用于氣象學中描述空泡在液體或氣體中形成的情況。這個詞的詞源和相關單詞反映了其在科學和工程領域的廣泛應用。

cavitation短語：

1. cavitation erosion - 空化侵蝕

2. cavitation noise - 空化噪音

3. cavitation bubble - 空化泡

4. cavitation damage - 空化損傷

5. cavitation shock - 空化沖擊

6. cavitation phenomenon - 空化現(xiàn)象

7. cavitation layer - 空化膜

7. We need to study the causes of cavitation damage and find ways to prevent it. (我們需要研究空化損傷的原因并找到防止它的方法。)

英文小作文：

Cavitation is a phenomenon that occurs when a liquid flows over a sharp edge or under extreme pressure conditions, and it can cause damage to mechanical components. In my opinion, we should pay more attention to the maintenance of mechanical equipment to avoid cavitation damage and improve equipment efficiency. For example, we can regularly check the water pump, turbine blade, and other components to ensure that they are in good condition and avoid unnecessary damage. In addition, we can also improve the design of mechanical components to reduce the occurrence of cavitation, such as using smooth edges and reducing pressure differences between different parts of the equipment. By doing so, we can not only improve equipment efficiency but also reduce maintenance costs and improve overall production efficiency.
