天平使用精度决定了物体称量的准确性,也是衡量天平仪器使用价值的重要标准。化工生产涉及到多种原材料的搭配组合,实验人员必须控制好物质原料占有的比例,保证化工成品符合客户的质量指标。受到多方面因素的影响,化工业天平使用精度偏低,给新产品研发带来了诸多不便。针对这一点,本文分析了天平精度的影响因素,提出避免仪器精度受损造成的不利。 The accuracy of the balance determines the accuracy of the object weighing, but also an important measure of the value of the balance instrument. Chemical production involves a combination of a variety of raw materials, the experimenter must control the proportion of material raw materials to ensure that chemical products meet customer quality indicators. Affected by many factors, the use of chemical balances is low, bringing many inconveniences to the development of new products. In response to this point, this paper analyzes the factors that affect the accuracy of the balance and proposes to avoid the disadvantage caused by the impaired accuracy of the instrument.
