摘要
目的:对骨钻不锈钢材料的酸碱度进行测试,识别不确定度影响的若干重要因素;方法:对A类与B类不确定度的分别评定,并比较B类不确定度主要因素的影响;结果:确定其不确定度来源的主要影响因素;结论:检测设备和玻璃仪器占据B类不确定度来源的主导因素,提出了降低不确定度影响的若干方法。
Objective:to test the pH of bone drill stainless steel and identify some important factors affecting the uncertainty;methods:class A and class B uncertainty were evaluated respectively,and the effects of the main factors of class B uncertainty were compared;results:the main influencing factors of the source of uncertainty were determined;conclusion:testing equipment and glassware are the dominant factors of class B uncertainty,and some methods to reduce the influence of uncertainty are put forward.
