The correction of the method of equivalent cycle number 非稳定变应力下疲劳强度计算的等效循环次数法的修正
Results : the optimal pool size , programming of matlab , and the steps of trials of the 2 approaches were given 结果:给出了最小检测次数法和序贯检验法的最优混合样本计算方法、 matlab程序和具体操作步骤。
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。
What has been included in our active norm is still prescribed - based code , that is the method based on volume change times , which has fallen into disuse in development country and has been proved to be so simple and inaccurate as to lead to great mistake sometimes 而我国目前在该领域的研究尚处于起步阶段,现行的规范中仍采用已经被发达国家淘汰的“处方式”的设计方法:体积换气次数法,该方法已被证明过于简单、粗糙,有时甚至导致错误。
