秤是称量工具,大家所熟知的有木杆秤、案秤、台秤、地秤和轨道衡等等。这些秤大多数利用杠杆原理,通过一套机械系统使被称重物与秤砣相平衡,就可以在标尺的刻度上读出重物的质量来。由于现有的机械秤在操作上不方便、工效低、不能适应工矿企业、运输部门、科研单应、商业和外贸系统以及国防工程中日益增长的需要,因而就出现了新的一种秤——电子秤。
Weighing scales are weighing tools, we all know are wooden scales, case scales, scales, scales and rail scales and so on. Most of these scales use the principle of leverage to balance the weighed object with the scale through a mechanical system so that the weight of the object can be read on the scale of the scale. Due to the inconvenient operation and inefficiencies of the existing mechanical scales and the inability to meet the growing needs of industrial and mining enterprises, transportation departments, scientific research institutes, commercial and foreign trade systems and national defense projects, a new kind of scale- - Electronic scales.
