机械天平在很长的一段时间内承担了全国质量量值传递的重要工作。随着科学技术的不断进步,设备和人员的更新换代,机械天平的使用频率越来越小,但总还有一些计量部门由于财力有限,对大质量砝码的检定还在使用机械天平,文章介绍了两种方便可行的检定方法,来确保量值传递的可靠性,供同行参考。
Mechanical balances took a significant part of the national mass transfer of value over a long period of time. With the continuous improvement of science and technology, the upgrading of equipment and personnel, the use of mechanical balance more and more small, but there are always some measurement departments due to limited financial resources, the weight of the test is still using a mechanical balance, the article Two convenient and feasible verification methods are introduced to ensure the reliability of the value transfer for reference by peers.
