摘要
通过75%硫酸法测定聚酯纤维与粘纤混纺产品纤维的含量,分析和评定测定过程中影响实验结果的各个不确定因素的相对贡献。结果显示,检测过程中所产生的测定不确定度主要来源为测量的重复性和电子天秤的系统效应所产生的不确定度。
The content of polyester fibers and viscose fibers was determined by 75%sulphuric acid method.Analysis and evaluation of the relative contribution of various uncertainties affecting the test results in the determination process.Results show that the main sources of uncertainty in measurement are the repertability of measurement and the systematic effect of electronic scale.
