Few minor injuries are as painful as the dreaded paper cut.Just thinking about it probably makes youcringe(畏縮).However,these cuts are usually small,hardly noticeable,and rarely bleed.So what makes them so painful?
很少有一些小傷能夠像被紙劃傷那樣讓人疼痛和害怕。光是想一想可能就讓你不寒而栗了。然而,這種劃傷通常傷口很小、很難被察覺到并且不怎么會流血。那為什么被紙劃傷會這么疼呢?
A paper cut is similar to a cut with arazor blade(剃須刀刀片),with one major difference.A razor blade makes a smooth,cleanincision(切口)in the skin,leaving behind few if anyforeign particles(異物)that might cause the wound to become infected.Although it might hurt initially,the pain brought on by a small razor cut usually fades after a few minutes.
被紙劃傷跟被剃須刀片劃傷很像,但是有一點不同。剃須刀片造成的傷口較為平整,幾乎不會留下任何會導(dǎo)致傷口感染的異物。雖然剛被剃須刀片劃傷的時候很疼,但是過幾分鐘疼痛感就會慢慢消退。
Like a cut by a razor blade,a paper cut smoothly parts the skin,but while a clean razor leaves little behind toirritate(刺激)the wound,a paper cut leaves material that reallystings(劇痛).
被紙劃傷的傷口和剃須刀片造成的傷口一樣,也很平整。但是干凈的刀片不會留下任何物質(zhì)去刺激傷口,而紙劃傷口卻會留下一些讓人感到疼痛的物質(zhì)。
Paper is made of pressedwood mulch(壓縮木片),and a variety of chemicals.When paper cuts into the skin,chemicals,as well as bacteria and tinyparticles(細菌)remain in the wound and stimulate pain receptors in the skin.
紙是由壓縮木片和多種化學(xué)物質(zhì)構(gòu)成的。當(dāng)紙劃過皮膚時,化學(xué)涂層纖維、細菌和細小顆粒物就會留在傷口里,對皮膚里的痛覺感受器產(chǎn)生刺激。
Since the cut is usually small andshallow(淺的),the skin on either side of the wound closes quickly,leaving the chemicals and other particles inside.The result is a good deal of pain,and since the closed wound doesn’t allow for much bleeding,the pain seems entirelyout of proportion(不成比例)to a cut that you canbarely(幾乎沒有)detect(發(fā)現(xiàn)).
由于傷口通常很小且很淺,傷口會很快愈合,同時會把纖維和其他粒子留在傷口里面。所以,你才會感到十分疼痛,由于閉合的傷口幾乎不會流血,所以說,即使傷口小到你幾乎察覺不到,但是傷口造成的疼痛感卻是要人命的!
