The definition of the absolute value for a fuzzy number is obtained.Furthermore,a lot ofproblems,such as absolute integrability,bounded variation and absolute continuity,arepresented and discussed.The representation theorem of the absolute values of fuzzy num-bers is established.It plays an important role in discussing the problems conceming theabsolute value.The relation between the absolute integrability and integrabili-ty is discussed,and the following result is obtained:aintegrable fuzzy-number-valued function is absolutely integrable iff it is integrable.The relation between theabsolute integrability and the absolute continuity of the primitive for fuzzy-number-valuedfunctions is dealt with.It is also pointed out that a fuzzy number valued function is ab-solutelyintegrable if and only if its integral primitive is fuzzy absolutely continuous.

Though comparing Canny operator and center B spline dyadic wavelet, the following conclusion is proven in this dissertation: a Center B spline function has tight support and Canny operator hasn't. b Center B spline function asymptotic convergence to Gaussian function and the derivative of Center B spline function asymptotic convergence to Canny operator. c The derivative of fourth order center spline B function is more suitable as a optimal edge detector than Canny operator. d Center B spline function can balance the smoothing and approximation of original data, and the fourth center B spline function is the only optimal solution of two order smoothing problem. e The error between the valve of time-frequency uncertainty of the fourth center B spline function and the lower bound of time-frequency uncertainty does not exceed 0.143% of the lower bound. f The derivative of center spline B function can construct a stability dyadic wavelet and can give a fast algorithm for multiscale edge detection, but Canny operator can do neither.

This article has sorted out the data of indefinite integral concept in common use, and has analyzed the features of three methods of indefinite integral in common use: the first substitution method of integration, the second substitution method of integration, and integration by parts.
因为,(x2)′=2x,(x2+1)′=2x,(x2+2)′=2x,(x2+c)′=2x所以x2,x2+1,x2+2,x2+c均为2x的原函数。由此得出:一个函数若有原函数存在则有无数个原函数存在,且任意两个原函数之间相差一个常数。

中文摘要:本文利用Taylor展开得到三角形上线性Lagrange插值和三次Lagrange插值的导数余项公式,对这些余项公式进行分析,给出了两类能以四阶精度逼近被插函数在对称点的导数值的格式,一种是在均匀剖分时其分片线性插值的相邻单元的导数值的后处理格式,一种是在六片强正规剖分时的三次插值在对称点上的导数值的后处理格式,使得在已知原函数在各节点的值后,通过一个简单的线性计算就可得到原函数在对称点的导数的一个超逼近值,将以往提出的平均导数的二阶精度提高到四阶。
