在物理实验的测量中,经常要涉及到灵敏度、准确度、精密度,它们表示什么意思?怎样表示它们?它们对实验测量有什么影响?一、灵敏度顾名思义,反映仪器的灵敏程度。仪器在使用时,由于被测量的变化必引起仪器指示部分的位置移动,移动的距离越大,仪器的灵敏度越高。一般是把指示部分的位移与被测量的变化值的比值定义为仪器的灵敏度。
In the measurement of physical experiments, it often involves sensitivity, accuracy, precision, what do they mean, how do they behave, and what effect do they have on experimental measurements? 1. Sensitivity, as the name implies, reflects the sensitivity of the instrument. When the instrument is in use, the position of the indicating part of the instrument must be moved due to the change of the measurement. The greater the distance moved, the higher the sensitivity of the instrument. It is generally defined as the ratio of the displacement of the indicated part to the measured change value as the sensitivity of the instrument.
