The autocorrelation function is an even function . 自相关函数是一个偶函数。
An integral property and its physical significance of difinite integral , double & triple integral , curve and curved surface integral of generalized odd and even functions are demonstrated , which are symmetrical about plane , line and point in the domain 论述了关于面、线、点对称的区域上的广义奇、偶函数的定积分、二重、三重积分、曲线、曲面积分的一个性质及其物理意义。
Generalize the integral characters of the odd and even functions of the unary definite integral in the symmetrical interval about the origin are generalized to the double integral of binary symmetrical functions in the symmetrical region , where similar characters are obtained 摘要导出了把一元定积分中奇、偶函数在关于原点的对称区间上的积分性质推广到在对称区域上的二元对称函数的二重积分的情形。
