%X Sample size justification is required for all clinical studies. However, to many biomedical and clinical researchers, power and sample size analysis seems like a magic trick of statisticians. In this note, we discuss power and sample size calculations and show that biomedical and clinical investigators play a significant role in making such analyses possible and meaningful. Thus, power analysis is really an interactive process and scientific researchers and statisticians are equal partners in the research enterprise.<BR>所有的临床研究都需要对样本量进行辨证。然 而，对于众多生物医学和临床研究人员来说，把握度 和样本量看起来就像一个统计学家的魔术。在本文中， 我们讨论了把握度和样本量的计算，并说明生物医学 和临床研究人员在该分析的可行性和意义中具有重要 作用。因此，把握度分析的确是一个互动的过程，并 且科学研究人员和统计人员在研究团队中是平等合作 的伙伴。.
