"有时候，在提炼的过程中会出现这些情况：一个气泡没有被移除，一个砂粒没有熔化，（熔融的）锡的一次颤动把波纹带进了玻璃带中。

Occasionally, a bubble is not removed during refining, a sand grain refuses to melt, a tremor in the tin puts ripples into the glass ribbon.

倒啤酒的时候也会起泡，不过即使啤酒已经倒好了，溶解在酒里的气体，主要是二氧化碳，就会跑出来并在玻璃杯壁的成核处变成小气泡。

The act of pouring will generate foam in beer, but even once the beer is poured, dissolved gas, chiefly carbon dioxide, will break out into small bubbles at nucleation sites along the glass wall.

那些气泡出现的原因在于：热胀冷缩时，车贴薄膜的延展性和车窗玻璃大不相同。

Those bubbles arise because the thin sticker film expands at a different rate than the window glass when they both heat up.
