When you have to sneeze or cough, do it into the bend of your arm.
當(dāng)你馬上要打噴嚏或咳嗽的時(shí)候，記得用手臂擋一下。
Sneeze into your arm with Elmo. Ah-choo!
和埃爾默一起打噴嚏吧，阿嚏！
Gordon and Elmo from Sesame Street are right.
芝麻街的戈登和埃爾默說的很對。
And MIT researchers recently found that viruses can travel much further than we thought.
而麻省理工學(xué)院的研究人員們最近就發(fā)現(xiàn)病毒的移動(dòng)距離比我們想象中要遠(yuǎn)的多，
Which shows how important it is to block coughs and sneezes.
這就說明阻隔咳嗽和噴嚏的必要性。
The researchers used high-speed imaging of folks coughing and sneezing, along with simulations and mathematical models.
研究人員使用高速動(dòng)態(tài)掃描成像記下人們咳嗽和打噴嚏的全過程，之后進(jìn)行數(shù)據(jù)模擬和模型分析。
The new research shows that multiple drops travel in a cloud.
這項(xiàng)新的研究顯示呈云霧狀軌跡的眾多顆粒物。
And the cloud’s turbulence pulls in surrounding air, which allows the goopy assemblage to maintain buoyancy and move farther.
這種云式湍流可以攪動(dòng)周圍空氣，從而使得粘稠物得以維持浮動(dòng)形態(tài)并移動(dòng)更長距離。
Heavier particles drop out first, but about five times further out than had been previously predicted.
較重的顆粒物最先下落，但仍然比之前預(yù)測到的距離遠(yuǎn)5倍以上。
And the small ones swirl around and can be carried 200 times past previously predicted distances.
小的顆粒物則會(huì)呈現(xiàn)蝸旋狀態(tài)并且是預(yù)測的實(shí)際能移動(dòng)距離的200倍之多。
The research is in the Journal of Fluid Mechanics.
這項(xiàng)研究已在《流體力學(xué)》雜志上發(fā)表。
Longer flight distances means coughs and sneezes can often reach ventilation systems.
遠(yuǎn)距離意味著咳嗽和噴嚏能更頻繁的到達(dá)通風(fēng)設(shè)備處。
The researchers thus encourage hospital and airplane engineers to consider designs that block droplet flight and thus keep everyone else from catching your cold.
研究人員們因此鼓勵(lì)負(fù)責(zé)醫(yī)院和航空飛行器的工程師們考慮設(shè)計(jì)可以阻斷顆粒物飛行的輔助裝置，從而可以保持周圍附近的人與病毒攜帶傳播者之間更有效的空氣阻隔。
