百科知識視頻之煎蛋小學堂72 響屁不臭，臭屁不響

You may have laughed at the idea of Silent But Deadly farts.But is this faint flatulence really more potent than the boisterous wind you let loose?Are silent farts actually worse ?It may surprise you to find out that a large portion of farts are the result of swallowed air.Whether from chewing a lot of gum,drinking pop,or simply from eating food,excess air enters your body and has to go somewhere.

你或許笑話過“臭屁不響”的說法。不過 無聲的屁真的比響屁來的更猛烈嗎?不響的屁真的更臭嗎?你或許會驚訝地發(fā)現(xiàn)屁在很大程度上由你吞下的空氣組成。無論是嚼的口香糖喝的軟欽料 還是吃的食物，進入你身體的多余空氣總得有個歸宿。

And while some is released through burping.the rest ends up in the digestive system and eventually comes out your other end.But when expelled,this gas is made of mostly nitrogen,hydrogen and carbon dioxide,all of which are odourless.Which explains why some farts are obnoxiously loud,but contain little to no smell.The second half of the equation is gas from the large intestine.After travelling through 25 feet of small intestine,the indigestible portions of food make their way to the colon.

一部分通過打嗝釋放出去，剩下的跑到了你的消化系統(tǒng)內 并從另一個口跑出去。你放出的香香的屁主要由氮 氫和二氧化碳構成，它大多是無味的，這就是為什么響屁一般沒什么味，屁的另一個主要來源是大腸中的氣體。在穿過25尺小腸之后，無法消化的食物跑到了結腸里。

Here,millions of bacteria feast on the remaining food,and ferment it.And this is where things can get...stinky!Though the bacteria do release some useful vitamins,they also produce chemicals containing sulfur,which is responsible for the smell in flatulence.Add to that a sulfur rich diet with things like eggs,meat or broccoli,and you're likely to produce some interesting odours.

在這里 數(shù)百萬的細菌享受著殘羹盛宴 并將其發(fā)酵。這就是臭味的來源了!盡管這些細菌會釋放一些有用的維生素，它會產生硫化物 這也是臭氣的罪魁禍首。多吃點雞蛋 肉類或者西蘭花等富硫食物，你就能釋放很多神奇的味道。

The longer these foods stay in the gut,the more they ferment and smell.Still,this smelly portion accounts for around only 1% of most farts.In the absence of the other odourless gases,however,these farts are concentrated with smell and generally quiet because there is less volume.Silent,but deadly!Having said that,loud gas can be just as smelly as the quiet ones,if the sulfur components are there.

食物在內臟中儲存時間越長 發(fā)酵程度就越高 氣味也越大。不過 大多數(shù)屁中 臭氣僅占總量的1%。但如果少了其他無味的氣體，由于體積更小 這些屁通常味道很大 卻沒什么聲。這是靜悄悄的毒氣彈!話說回來 響屁也可能與悶屁一樣臭，如果里面硫化物夠多。

Simply put,you loud farts likely contain a higher proportion airborne,odourless gases,whereas the quieter flatulence tends to have a higher proportion of the smell.

簡單地說 響屁中無味聲響氣體的比例較大，而悶屁中臭氣物質所占的比例更高。
