也许你已体会到,当盯着香槟气泡从杯中流溢时,你的视觉享受也会随之变化。一项新研究发现,香槟气泡的浓度取决于酒杯的形状。

Champagne. Do you drink it out of a narrow flute or the broader, more shallow coupe?
你喝香槟时用细长玻璃杯还是广口浅杯?

You may have noticed that your perception of the bubbly wine changed as gas escaped from it, and new research finds that the concentration of gas depends on the glass.
也许你已体会到,当盯着香槟气泡从杯中流溢时,你的视觉享受也会随之变化。一项新研究发现,香槟气泡的浓度取决于酒杯的形状。

French researchers, but of course, monitored the concentration of ethanol and carbon dioxide in each type of glass for 15 minutes after champagne was poured. They discovered that there was a much higher concentration of carbon dioxide in the tall flute than the broad coupe.
法国研究人员做了一项实验:将香槟倾入形状各不相同的酒杯中,然后对杯中乙醇和二氧化碳的浓度进行15分钟的监测。他们发现,细长酒杯中香槟的二氧化碳浓度要比广口浅杯中香槟的二氧化碳浓度高出很多。

Infrared imaging of the glasses gave a visual confirmation. Although the glass shape did not affect the concentration of ethanol vapor, the temperature did, with chilled champagne releasing less ethanol, but the same amount of carbon dioxide. The work is in the journal Public Library of Science ONE.
对酒杯进行的红外成像检测更直观地印证了这一研究结果。虽然酒杯的形状并不影响乙醇蒸气的浓度,但对于释放少量乙醇的冰镇香槟而言,酒杯形状却能对相同数量的二氧化碳产生影响。这项研究成果刊登于《科学公共图书馆》杂志上。

Based on their findings, the researchers were able to construct a model for how carbon dioxide moves from liquid to gas. And for champagne drinkers, the finding may help them choose the perfect glass. Cheers.
基于这一发现,研究人员就能建立一个模型以模拟二氧化碳从液体转化为气体的过程。而对于香槟爱好者而言,这一发现可以帮助他们选择合适的酒杯。来,为这一成果,我们干一杯吧。

重点讲解

1. concentration n.专注,专心;集中;浓缩,浓度
例句:The tennis players need total concentration during play. 网球运动员在比赛中需要全神贯注。
It is necessary to enrich the fuel by increasing the percentage concentration of uranium-235. 必须提高铀235浓度的百分比,使燃料浓集。

2. monitor vt.监听(视;测)
例句:I monitor the interview back at Leconfield House on the seventh floor. 我在莱肯菲尔德大厦的七层楼上监听这次会见。

3. release t..释(排)放;解脱;放开;发布(行)
例句:Plant growth and nutrient release are directly related. 植物生长量与养分释放量是正相关的关系。

4. construct vt.建造;构思
例句:It is required to construct an access bridge over a motorway. 要求跨 过公路建造一座跨线桥。
