一、减小测量误差的方法1.减小随机误差的方法由于随机误差一般来源于影响量的随机变化(亦称为“随机效应”),导致测量结果的分散性。虽然无法完全消除,但通过改善测量条件,严格控制测量环境的变化,如温度波动、湿度、振动、电磁波、电压、频率的变化等因素的影响,采用高分辨力、高准确度的仪器和标准,可减小随机误差的影响。另一种途径是在重复条件
First, the method to reduce the measurement error 1. Method to reduce the random error Random error due to random error is generally derived from the impact of random changes (also known as “random effects ”), resulting in the dispersion of measurement results. Although it can not be completely eliminated, it improves the measurement conditions and strictly controls the changes of the measurement environment, such as temperature fluctuation, humidity, vibration, electromagnetic wave, voltage and frequency, and adopts the instruments and standards with high resolution and high accuracy , Can reduce the influence of random error. Another way is to repeat the conditions
