| 摘 要： | 摘要：采用Monte—Carlo方法，以无偏性与有效性为依据，确定评判指标并研究几种频率曲线的稳健性．为了使研究成果具有代表性，对各种分布的3组不同总体分别抽取1000组样本(每组样本容量为60)进行计算与评判．结果表明，在目前常用的分布曲线中，P．Ⅲ型分布具有较强的稳健性．

| Abstract: | The steadiness of several frequency curves and their judgment criteria were studied based on the unbiasedness and effectiveness by use of the Monte-Carlo method. One thousand groups of samples (the capacity of each group being 60) extracted from 3 different populations of various distributions were calculated and judged to ensure the high universality of the research results. The research shows that, among the distributions commonly used, the P-III distribution is of high steadiness. |
