摘　　要：为了缩短我国生丝检验标准与国际上的差异,加快生丝电子检测进程,根据抽样分级理论探讨了在生丝纤度电子检验中各个筒子间的纤度均匀度变异(CVbeven%,简写成CVb%)的分布及以其为质量指标的分级标准制定问题。通过将理论结论与实际测试数据相结合,得到了纤度均匀度变异的分布,并给出了其抽样分级方案及各等级分级精度。In order to shorten the difference of the size grading standard for raw silk between China and the world, quicken the step of electronic raw silk testing process, the distribution of variation coefficient （CVbeven%, abbreviated to CVb%） of the size evenness between each bobbin in the electronic testing and the institution of the new CVb% standard were discussed according to the sampling and grading theory. By combining the theoretical deduction with the actual experimental data, the paper gave the distribution of CVb%, and proposed the grading draft of CVb% and the grading precision of each grade.
