无声的屁更加糟糕么?

Are Silent Farts Worse?

你也许嘲笑过“响屁不臭”的说法。但是你放出的这个微小的肠胃胀气
You may have laughed at the idea of ‘Silent But Deadly’ farts. But is this faint flatulence
真的比响屁更可怕吗?无声的屁真的更糟糕吗?
really more potent than the boisterous wind you let loose? Are silent farts actually worse?
你可能会惊讶大部分的屁是由你吞咽的空气组成的
It may surprise you to find out that a large portion of farts are the result of swallowed
不管是嚼口香糖,喝汽水或只是简单地吃了食物,过量空气
air. Whether from chewing a lot of gum, drinking pop, or simply from eating food, excess air
会进入你的身体并且到达一些地方 一些事通过打嗝释放,
enters your body and has to go somewhere. And while some is released through burping,
而剩下一部分在消化系统停止,然后变成屁放出去 但是当
the rest ends up in the digestive system and eventually comes out your other end. But when
它被排除的时候,这种气体大部分是氮气,氢气和二氧化碳
expelled, this gas is made of mostly nitrogen, hydrogen and carbon dioxide — all of which
这些都是无味的 这就解释了为什么一些让人反感的大声的屁,包含很少
are odourless. Which explains why some farts are obnoxiously loud, but contain little to
或几乎没有气味
no smell.
第二大部分的屁是来自大肠 在经过了
The second half of the equation is gas from the large intestine. After travelling through
25英尺的小肠之后,难消化的部分食物来到了结肠
25 feet of small intestine, the indigestible portions of food make their way to the colon.
这里,数百万的滋生细菌停留在食物上酝酿发酵 这里就是会把屁
Here, millions of bacteria feast on the remaining food, and ferment it. And this is where things
变臭的地方 虽然这些细菌确实释放了一些有用的维生素,但同样也制造了
can get…stinky! Though the bacteria do release some useful vitamins, they also produce chemicals
使屁变臭的化学含硫物质
containing sulfur, which is responsible for the smell in flatulence. Add to that a sulfur
像鸡蛋,肉或西兰花等都是会增加硫的食物,并且很可能产生一些很不可描述
rich diet with things like eggs, meat or broccoli, and you’re likely to produce some interesting
的味道 这些食物停留在肠道越久,发酵越多,味道越臭 当然,
odours. The longer these foods stay in the gut, the more they ferment and smell. Still,
大多数屁中,臭屁的部分只占了1%
this smelly portion accounts for around only 1% of most farts.
但是少了其他的无味气体,因为没什么声音,
In the absence of the other odourless gases, however, these farts are concentrated with
这些屁就变得无声而臭了 这就是响屁不臭!有这样的说法
smell and generally quiet because there is less volume. Silent, but deadly! Having said
如果有含硫物质,响屁也会变成跟无声的屁一样臭
that, loud gas can be just as smelly as the quiet ones, if the sulfur components are there.
简单来说,响屁很可能在无味声响气体的比例较大
Simply put, your loud farts likely contain a higher proportion airborne, odourless gases,
但无声屁有味道的比例更高
whereas the quieter flatulence tends to have a higher proportion of the smell.
