摘　　要：根据统计学理论指出了NY/T32 7- 1997家蚕成品卵微粒子病抽样检验行业标准的缺陷 :不同批次蚕种的控制标准不一 ,不能很好地控制“弃真”错误的概率。运用概率统计方法 ,提出了改进的抽样检验方案。用此方案进行的抽样检验不仅可保证将不合格蚕种判为合格蚕种的概率控制在 1 5 %以内 ,而且可减少将合格蚕种判为不合格蚕种的概率。According to the statistics theories, the author pointed the blemish of the profession standard of NY/T327-1997: The control standard of different silkworm egg-batch is different. It can't nicely control probability of “the first error”. Making use of the method of probability and statistics, the author brought up the improved plan about pebrine-collective inspection of silkworm eggs. Using this plan, the probability that the unqualified silkworm eggs are judged to qualified silkworm eggs is less than 1.5% and the probability that the qualified silkworm eggs are judged to unqualified silkworm eggs are decreased.
