试论检定砝码的电子天平的选择

On the Selection of Electronic Balance for Checking Weights

随着科技和经济的快速发展,电子天平在生活中的应用越来越广泛。与其他测量工具相比,电子天平测量得更加准确。本文主要对电子天平检定中选择标准砝码中的要求、电子天平的不确定度的计算以及电子天平选择中的误区进行介绍,从而提高电子天平测量的准确度。

With the rapid development of science and technology and economy, the electronic balance is becoming more and more widely used in life. Compared with other measuring instruments, the electronic balance is more accu.rate. This paper introduced the requirements of the standard weight, the calculation of the uncertainty of the electron.ic balance and the misunderstanding in the selection of the electronic balance, so as to improve the accuracy of the electronic balance test.
