鼻子的嗅觉可能比我们认为的灵敏得多,美国《科学》杂志20日刊登的一项新研究显示,人类的鼻子理论上可以嗅辨至少1万亿种气味,而不是先前认为的1万种。尽管人眼可以区分数百万种颜色,人耳可以听出约50万种音调,但学术界一直认为,人类鼻子只能嗅辨大约1万种气味。参与研究的美国洛克菲勒大学教授莱斯利·沃歇尔说:“我们的研究显示,人类嗅辨气味的能力比任何人预想的都要强大得多!” The smell of the nose may be more sensitive than we think, a new study published in the U.S. Science on the 20th shows that the human nose can theoretically smell at least 1 trillion odors rather than the previously considered 10,000 . Although the human eye can distinguish millions of colors, the human ear can hear about 500,000 tones, but academics have always believed that human nose can only smell about 10,000 kinds of smell. Leslie Waucher, a professor at the University of Rockefeller who is involved in the study, said: “Our research shows that humans are much more capable of smelling odors than anyone expected!” "
