摘　　要：文中证明了周期函数在任何一个周期长度的区间上计算所得傅里叶级数相同 。In the article it is proved that Fourier Series of periodic function is the same, which is obtained in any interval whose length is equal to a period and therefore it can be simply calculated by choosing appropriate integral interval.

关 键 词：周期函数 傅里叶级数 可积函数 积分区间
