沸石是一种多孔性物质，通常用于防止液体过热而导致的暴沸。然而，沸石不能直接加入正在沸腾的液体中，原因如下：

　　Zeolite is a porous substance commonly used to prevent boiling caused by liquid overheating. However, zeolite cannot be directly added to boiling liquids for the following reasons:

　　防止暴沸 ：沸石表面的小孔中存有空气，当沸石加入热液体时，会突然释放出大量蒸汽，导致液体剧烈暴沸，可能会使液体冲出瓶口，造成危险。

　　Prevent violent boiling: There is air in the small holes on the surface of zeolite. When zeolite is added to a hot liquid, it will suddenly release a large amount of steam, causing the liquid to boil violently, which may cause the liquid to flush out of the bottle mouth and pose a danger.

　　操作 ：如果液体是易燃的，加入沸石可能会引起火灾。

　　Safe operation: If the liquid is flammable, adding zeolite may cause a fire.

　　正确的操作方法是在液体冷却沸点以下后再加入沸石，以确保沸腾过程平稳，并防止暴沸现象的发生。使用过的沸石一般不能再继续使用，因为其微孔中可能充满或留有杂质，导致孔径变小或堵塞，从而失去助沸作用

　　The correct operating method is to add zeolite after the liquid has cooled below its boiling point, to ensure a smooth boiling process and prevent the occurrence of violent boiling. Zeolite that has been used should generally not be reused as its micropores may be filled with or contain impurities, leading to a decrease in pore size or blockage, thereby losing its boiling aid effect
