摘　　要：在《与荷载同步变化的时间步自动调整方法》^([1])中提出的时间步自动调整方法,不同于以往的后验式误差评估时间自适应方法,它是先验式误差评估研究领域的一次有益尝试(Apriori Time Adaptive Method,ATAM)。为了使ATAM更好的应用到实践中,就ATAM的适用条件和如何使用的问题进行了探讨,得出了几点非常重要的结论和建议。The time step automatic adjustment method proposed in “Time step automatic adjustment method synchronously varying with load changes” is different from the past posteriori error estimation time adaptive one, it is a useful attempt in the field of apriori error estimation study, and it is called the apriori time adaptive method (ATAM). In order to better apply the ATAM in practice, its applicable conditions and some problems how to use it were explored here, and some very important conclusions and recommendations were drawn.
