新闻背景:
Each person will wear a special mask and breathe normally for 10 minutes. The mask is equipped with collection tubes.____________________________________.The lead investigator is Rebecca Fitzgerald of Cambridge University in England. She says the Owlstone breathalyzer is a simple device. \"These tubes -- simple though they look -- this is one of the things that\'s made a real difference in this technology looking so promising, because for the first time the chemicals that are breathed out in the breath, can be collected in these tubes and immediately stabilized. So as you keep breathing you\'re capturing more and more of those chemicals and you\'re building up a profile of the chemicals in your body that are being exhaled on the breath.\"每个人将戴上一个特殊的面具,正常呼吸10分钟。口罩上装有收集管。____________________________________。首席研究员是英国剑桥大学的丽贝卡·菲茨杰拉德。她说Owlstone酒精测试仪是一个简单的设备。“这些管子——虽然看起来很简单——这是使这项技术看起来很有前途的真正的不同之处之一,因为第一次,在呼吸中呼出的化学物质,可以在这些管子中收集,并立即稳定下来。”所以当你继续呼吸的时候,你就会捕捉到越来越多的化学物质,从而描画出你身体中呼出的化学物质的轮廓。
