摘　　要：考虑周期未必相同的周期函数之和在无穷远处的极限性质与周期函数本身取值范围的关系.得出了一些有趣的性质,也提出了进一步的问题.For the sum of periodic functions,it is considered the relationship between its limit properties of at infinity and the bound of the function itself.Some interesting properties are yielded and further problems are provided.

关 键 词：周期函数 极限性质 最佳常数
