"An average person, "Roach explains, "will, during the peak flatulence period, pass anywhere from one to almost three cups of flatus per hour."
“一个普通人，”罗奇解释道，“在肠胃最胀气的时候，每个小时会放出1到3杯的的屁。
I didn't know the U.S. Department of Agriculture once had a flatus researcher.
我不知道美国农业部曾经有一位研究肠胃胀气的专家。
He was interested in individual differences, not just in the overall volume of flatus, but in the differing percentages of constituent gases.
他感兴趣的是个体差异，不仅对肠胃气的总量感兴趣，而且对构成气体的百分比也感兴趣。
