(单词翻译)

 You have probably noticed that the synthetic1 shirts stinks2 more after a workout, compared to cotton. But hey, it's not the fabric's fault, it's the microscobes that hang out on synthetics3 that create the characteristic stach. That's according to a study in the journal Applied4 and Environmental Microbiology. Twenty six volunteers, half men, half women, worked out on spinning bikes for an hour and they did so outfitted5 with shirts of cotton, polyester or a cotton synthetic blent. Then the researchers stuffed the sweaty shirts into plastic bags. The next day, a trained panel sniffed6 them, rating their funk. Unlucky job , because,yes,  the polyester shirts indeed moremusty, sour and emonia-like than the cotton. DNA7 analysis revealed that micrococcus bacteria were to blame. They aren't that common in the armpit itself, and they don't flock to cotton. But researchers say they thrive on the open-air latus of synthetic fibers8 where they sit chopping on the long chain fatty accid in our sweat, turning them into shorter, stinkier molecules9.  This finding might just explain one of the most vexing10 questions of adolescents," Why do the stinky shirts smell so differently unpleasant from the body odor and armpits themselves?" Could be, because your favourite shirt has a microbio itself.
