沸石是一種多孔性物質(zhì)，通常用于防止液體過熱而導(dǎo)致的暴沸。然而，沸石不能直接加入正在沸騰的液體中，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氣，當(dāng)沸石加入熱液體時，會突然釋放出大量蒸汽，導(dǎo)致液體劇烈暴沸，可能會使液體沖出瓶口，造成危險。

　　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.

　　安全操作 ：如果液體是易燃的，加入沸石可能會引起火災(zāi)。

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

　　正確的操作方法是在液體冷卻至沸點以下后再加入沸石，以確保沸騰過程平穩(wěn)，并防止暴沸現(xiàn)象的發(fā)生。使用過的沸石一般不能再繼續(xù)使用，因為其微孔中可能充滿或留有雜質(zhì)，導(dǎo)致孔徑變小或堵塞，從而失去助沸作用

　　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
