事实上，生产力的概念本身就是时钟的副产品：一旦工作表现与统一的时间单位可以联系起来，工作就永远都不一样了。
Indeed, the very notion of productivity is a by-product of the clock: once one can relate performance to uniform time units, work is never the same.
每个处理器内每组三个水平方框显示了在指定的时钟周期内，三个执行单位是如何被使用的。
Each set of three horizontal boxes within each processor shows how the three execution units are being used during a given clock cycle.
垂直组表明在一段时间内（多个时钟周期期间）利用了三个执行单位。
The vertical sets indicate the utilization of the three execution units over time (during multiple clock cycles).
