1、Peng's Coefficient is inversely proportional to Engel's Coeffient, because the more proportion people spend on food, the less proportion on culture and spirit.───彭氏系数通常跟恩格尔系数成反比，因为人们在食物上的支出比重越大，在精神文化上的消费往往会减少。
2、Or if a household does underreport its spending, he assumes that it also downplays its food expenses proportionately, so that their Engel’s coefficient is unaffected.───或者如果一个家庭少报了开支，他假设同一家庭同时也相应少报食物开支，这样恩格尔系数才不受影响。
3、In Mr Wang's survey, for example, the poorest people devoted 48% of their outlays to food, whereas the richest spent only 29% (an Engel's coefficient of 0.29).───比如在王晓鲁的调查中，最贫穷的人将收入中48%花费在食物上，而最富裕的仅为29%(恩格尔系数是0.29)。
