同学你好
[w]turnover[/w]（一定时期内的）营业额，成交量
[w]revenue[/w] 是指在一定时间内（通常为一年）的总收入，即年收入，还可以特指政府税收收入
[w]profit[/w] 单指利润，就是去掉本钱后的纯获利，总收入减去总成本所得，一般profit是绝对值

同学可以再参考下详细的英汉双解释义哈~
turnover可以表示货物的流动，人员的流转，还有证券交易额，这些意思是revenue没有的，具体英文释义如下：
1.a. The number of times a particular stock of goods is sold and restocked during a given period of time.
b. The amount of business transacted during a given period of time.
c. The number of shares of stock sold on the market during a given period of time.
2.a. The number of workers hired by an establishment to replace those who have left in a given period of time.
b. The ratio of this number to the number of employed workers.
