英语翻译
Plants can’t communicate by moving or making sounds,as most animals do.Instead,plants produce volatile compounds,chemicals that easily change from a liquid to a gas .A flower’s sweet smell,for example,comes from volatile compounds that the plant produces to attract insects such as bugs and bees.
Plants can also detect volatile compounds produced by other plants.A tree under attack by hungry insects,for instance,may give off volatile compounds that let other trees know about the attack,In response,the other trees may send off chemicals to keep the bugs away- or even chemicals that attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying:a chemical sensor(传感器) called an electronic nose.The “e-nose” can tell compounds that crop plants make when they’re attacked.Scientists say the e-nose could help quickly detest whether plants are being eaten by insects,But today the only way to detect such insects is to visually inspect individual plants.This is a challenging task for managers of greenhouses,enclosed gardens that can house thousands of plants.
The research team worked with an e-nose that recognizes volatile compounds.Inside the device,13 sensors chemically react with volatile compounds.Based on these interactions,the e-nose gives off electronic signals that the scientists analyze using computer software.

植物不能像大多数动物一样通过移动或发声进行交流.然而,植物能够产生挥发性化合物,这种化学物质可轻易的从液体转化为气体.例如:花香就是来源于挥发性化合物,植物用其吸收虫子和蜜蜂等昆虫.
植物还能够探测到其他植物产生的挥发性化合物.例如:受饥饿昆虫攻击时,树木会释放出挥发性化合物,让其他树木知道自己受到了攻击.随后,其他树林会做出反应,散发出化学物质使虫子远离,或是释放化学物质引来虫子的天敌.
当前,科学家发明了一种名为电子鼻的化学传感器,能够迅速解译出植物表达的语言.“电子鼻”能够分辨出农作物受到攻击时释放出的化合物.科学家指出,电子鼻能够迅速判断植物是否受到昆虫啃食.目前,检测这种害虫的唯一方法是对每株植物逐一进行目视检查.这对于温室管理人员来说是一项极具挑战性的工作,因为封闭的园圃可能种植着成千上万株植物.
研究小组使用电子鼻对挥发性化合物进行了判别.该装置内部有13个传感器,可与挥发性化合物发生化学反应.根据交互反应的结果,电子鼻会发出电子信号,供科学家使用计算机软件进行分析.
