| 摘 要： | 本文将细限纤度以下的纤度变动过程视为由纤度减少-纤度跃增2阶段构成的更新过程,导出在此条件下纤度对于细限纤度及丝条斑界限的初通过基本恒等式,由此给出该过程中匀度疵点发生概率的近似计算公式。并通过电子计算机模拟试验验证了理论的结果。

| Abstract: | In this paper, we described the size variance process under the limit size for cocoon feeding as a renewal process which is constituted by two stages; i.e. the size decreasing and the size jumping. Under the condition, we derived the fundamental identity on the first passage of size variance process to the limit size for cocoon feeding and the limit size of evenness defect occurring, and gave an approximate formula for calculating the probability of evenness defect occurring in this process. Then we verified those theoretical results by computer simulation. |
