在测量技术中不可能获得绝对精确的测量结果。除了特性曲线偏差等系统误差外，还有随着时间的推移而产生的误差。这种效应称为漂移。一个典型的例子是压力表的长期漂移，由于组件老化或其他影响，结果会随着时间的推移而发生变化。

　　Absolutely exact measurements are impossible to obtain in measuring technology. In addition to systematic errors such as the characteristic curve deviation, there are also errors that occur with the passing of time. This effect is called drift. A typical example is long-term drift in pressure gauges where the result changes over the course of time due to ageing of components or other effects.
