据美国商务部周三报告，美联储的主要通胀指标显示，消费者价格同比涨幅低于预期。
Consumer prices posted a smaller than expected increase from a year ago, according to the Federal Reserve's primary inflation gauge, the Commerce Department reported Wednesday.
个人消费支出价格指数（PCE）经季节性调整后环比上涨0.3%，使12个月累计涨幅达到3.4%。《华尔街日报》调查的经济学家此前预计涨幅分别为0.3%和3.7%。
The personal consumption expenditures price index increased a seasonally adjusted 0.3% for the month, putting the 12-month gain at 3.4%. Economists surveyed by Dow Jones had been looking for increases of 0.3% and 3.7% respectively.
剔除食品和能源后，PCE环比上涨0.2%，使年度核心水平达到3.0%。此前的预测值分别为0.3%和3.3%。
Excluding food and energy, PCE posted a 0.2% increase that put the annual core level at 3%. The respective forecasts were for 0.3% and 3.3%.
尽管美联储官方遵循PCE总体数据，但官员们通常认为核心数据是衡量长期趋势的更好指标。
Though the Fed officially follows the headline PCE number, officials generally consider core a better gauge of longer-term trends.
虽然年度涨幅低于预期，但这一结果是在经济分析局调整了该指数多个组成部分的计算方式后得出的。目前尚不清楚这些修订对最终数据产生了何种影响。
While the annual increases were less than expected, they came as the Bureau of Economic Analysis adjusted the way it computes several components of the index. It was not immediately clear what impact the revisions had on the final numbers.
