When the acceleration period has terminated, the switch means is controlled by a PWM pulse of the duty ratio in accordance with the speed instruction data, there by driving the DC motor.

在该加速期间结束时，以占空比与速度指令数据对应的PW M脉冲来控制开关机构，从而驱动该直流马达。

The CPU speed (in milliseconds per instruction) is used by the SQL optimizer to estimate the cost of performing certain operations.

SQL 优化器使用 CPU 速度（每条指令几微秒）来评估某些操作的执行成本。

In addition to processor clock speed, another important processor performance metric is clock cycles per instruction (CPI).

除了处理器时钟速度外，另一个重要的处理器性能度量是每条指令的时钟周期(CPI)。

Button's slightly less strict interpretation of the instruction was what was behind his greater speed at this phase of the race, rather than any intrinsic difference in their potential - which appeared to be extremely closely matched.
