Methods : formulas of the expected pooled sample size and the power of tests were deduced while controlling the probability of type and type errors
方法：在控制两类错误概率的前提下，推导两种方法的期望检测次数和检验功效的数学表达式。
The optimal pool sizes of the 2 approaches were given by minimizing the expected pooled sample size ; computer simulation was used to verify the outcomes
对最大期望检测次数进行数学优化，求解最优混合样本的大小，并通过计算机模拟对有关结果进行验证。
Objective : to provide a minimum sample size approach and a sequential sampling approach for testing whether the sporozoite rate has exceeded the critical level of malaria epidemics using the pool sampling method
摘要目的：给出基于混合样本的最小检测次数法和序贯检验法，以检验子孢子阳性率是否超过导致疟疾流行的临界水平。
Conclusion : the optimal pool size in the present study can obtain satisfactory testing power ( type and type errors are both lower than 5 % ) and can effectively decrease the pooled sample size
结论：利用本文给出的最优混合样本和检测步骤，在获得比较满意的检验功效（两类错误概率均低于5 % ）的同时，可以有效降低检测次数。
