Background: Response variability to clopidogrel therapy has been demonstrated.

背景：已有研究显示氯吡格雷治疗反应的变异性。

The slight difference in response time of 1 msec would not be perceivable, and is likely due to measurement variability.

响应时间的差异只有 1 msec，可以无需考虑，而且可能是由于测量的误差引起的。

The variability in response time is decreasing, so users see less variation when they press the Enter key.

所以当用户按 Enter 键时，响应时间的偏差更小。

Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities.
