摘　　要：为从不完整调查资料推算疾病潜伏期容许限和容许区间，假定观察次数（样本量）服从Poisson分布，引用复合整参数β-分布法计算疾病的潜伏期容许限和容许区间。获得以样本最小顺序统计量与最大顺序统计量为容许限，或以样本最大、最小顺序统计量差为容许区间的容许概率容许度，以及样本量服从Poisson分布参数的对应关系式。根据不完整调查资料提供的信息，结合数值举例，讨论如何有效合理地选择样本量的取样单位。To estimate the tolerance limit and the tolerance interval of disease incubation, under the theory that the observations （samples） were subject to Poisson distribution, the tolerance limits and tolerance interval of disease incubation were calculated based on beta-distribution with integer parameter. Expressions on the relation were obtained, including the statistics on tolerance limits of both minimum and maximum orders while the tolerance was the difference between minimum and maximum order statistics and the parameters of Poisson distribution on the sample size. Using the incomplete observations as an example, reasonable unit of sample size was considered and chosen.
