Concentricity Error of Core/ Reference Surface

It is discussed about the approximate relationship between silk reeling velocity and rawsilk size variance, and drawn the conclusion that the velocity doesn't affect the size deviationbasically under present reeling velocity.

研讨了缫丝速度与生丝纤度方差的近似关系,得出了在目前采用的缫丝速度下,缫丝速度对生丝纤度偏差成绩基本不受影响的结论。

On the basis of the theory of raw silk size deviation, investigations are conducted on the size deviation records and fluctuation in the inspection of raw silk after being shortened in its length from 400 turns to 100 turns,with discussions made on determining threshold value of the corresponding grade and quantity of sample silk to be tested.

基于生丝纤度偏差理论， 考察生丝纤度偏差检验丝长从４００ 回缩短为１００ 回时纤度偏差成绩及其波动状况； 讨论与此相关的等级界限值设定及检验样丝数量等问题； 提出改变检验丝长后划分纤度偏差等级的方法。

random end feeding, proportional cocoon matching and layer-based cocoon matching, upon the size deviation of raw silk.

分析了随机添绪、比例配茧、塔形配茧三种配茧方式对生丝纤度偏差影响的程度和趋势。
