3月31日，国家统计局服务业调查中心、中国物流与采购联合会联合公布了3月的PMI数据，数据为51.9。虽然超过了50，处于扩张区间，但与2月相比，还是掉了0.7个百分点。
顺着这个新闻，今天梳理几个跟“指数”有关的术语。
先看PMI、CPI、KPI等指数中都出现的词汇——index.(I)
【释义】 n.（物价和工资等的）指数
牛津：a system that shows the level of prices and wages, etc. so that they can be compared with those of a previous date
【例句】
1. PMI = purchasing managers' index 采购经理人指数
The Purchasing Managers' Index (PMI) is an index of the prevailing direction of economic trends in the manufacturing and service sectors. It consists of a diffusion index that summarizes whether market conditions, as viewed by purchasing managers, are expanding, staying the same, or contracting. （参考翻译：采购经理人指数(PMI)是反映制造业和服务业经济发展趋势的主要指标。它由一个扩散指数组成，概括了采购经理眼中的市场状况是在扩张、保持不变还是在收缩。）
2. CPI= consumer price index 消费者物价指数
（CPI指数计算通常涵盖8大类，图源网络）
The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.（参考翻译：消费者价格指数(CPI)是一种衡量一组消费品和服务(如交通、食品和医疗)加权平均价格的指标。它的计算方法是将预定一组商品中每种商品的价格变化取平均。）

3. PPI =Producer Price Index 工业生产者出厂价格指数
A producer price index (PPI) is a price index that measures the average changes in prices received by domestic producers for their output. PPI是衡量国内生产者产出的平均价格变化的价格指数。
4. HSI=Hang Seng Index 恒生指数
炒股的朋友对HSI应该不陌生——
The Hang Seng Index is a freefloat-adjusted market-capitalization-weighted stock marketindex in Hong Kong. It is used to record and monitor daily changes of the largest companies of the Hong Kong stock market and is the main indicator of the overall market performance in Hong Kong. （参考翻译：恒生指数是香港一个经自由流通调整的市值加权股市指数。它用来记录和监测香港股票市场最大公司的每日变化，是香港整体市场表现的主要指标。）
你还能想到哪些指数吗？
保持好奇心，每日，每月，每年，以求寸进。
