In this paper, we first give an example that the bilateral weighted shift operator in c_0space is hypercyclic operator and first solve the existence problem of hypercyclic operator in c_0or c_0(Z space . And then we investigate the property of weighted shift operator in c_0 space and an important property of the hypercyclic vector of weighted shift operator in c_0 space and c_0 space. At last we give the concept of weak hypercyclic operator and weak hypercyclic vector , and give the equivalence between the weak hypercyclicity and the hypercyclicity in l~1 space.

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.

作者给出了Canny算子与中心B样条二进小波严格的比较证明，得出如下结论：a中心B样条函数具有紧支集，Canny算子不具有紧支集。b中心B样条函数的极限收敛于高斯函数，中心B样条函数的导数收敛于Canny算子。c四阶中心B样条函数的导数比Canny算子更接近最佳边缘检测滤波器。d中心B样条函数比高斯函数更能兼顾对原函数平滑和逼近的折中要求，并且四阶中心B样条函数是二阶逼近问题的唯一最优解。e四阶中心B样条函数的时频测不准关系值与时频测不准关系下界的逼近误差不超过0.143％。f中心B样条函数的导数可以构成稳定的二进小波，存在快速的多尺度算法；而Canny算子不构成稳定的二进小波，无法给出快速的多尺度算法。

The generalized ordered weighted averaging operator is ob tamed by combining the ordered weighted averaging operator and the generalized mean operator. Based on the GOWA operator, the generalized uncertain ordered weighted averaging operator is proposed.

In chapter one,the backgrounds and current situation of operator theory in Banach space are introduced and the preliminaries of Banach space are given.In chapter two,we study the existence and uniqueness of fixed point for decreasing strict-set-contraction operator in product space.Under the weak continuous condition,we obtain the existence and uniqueness of fixed point for decreasing operator and we give an application of these results; In chapter three,we get several positive fixed point theorems of decreasing operator and the existence and uniqueness theorems of positive fixed point for operator C=A+B,C=D-A in real Banach space where the order is decided by a normal cone; In chapter four,we obtained some existence and uniqueness theorems of fixed point for some mixed monotone operators in semi-ordered Banach space.

On this release, Windham Hill collects six classic catalog tracks and adds two new ones each from highly regarded musician Adam del Monte and New Age artist Sean Harkness. Flamenco is inarguably the music of Spain, but this collection also highlights influences from the Middle East, North Africa, and Eastern Europe. Vicente Amigo's "Three Notes to Say I Love You" is a bit on the schmaltzy side, but it's nicely balanced by the intense fretwork on del Monte's "Sombra del Paraiso."

windham Hill公司发行了"windham Hill吉它曲集锦"展现了对于有着数百年古老传统的弗拉门戈的现代继承，这张专辑中汇集了近十年来流行的六首经典曲目，以及由adam Del Monte和广受欢迎的新世纪艺术家sean Harkness作曲的四首曲目。

As they approached the Piazza del Popolo, the crowd became more dense, and above the heads of the multitude two objects were visible: the obelisk, surmounted by a cross, which marks the centre of the square, and in front of the obelisk, at the point where the three streets, del Babuino, del Corso, and di Ripetta, meet, the two uprights of the scaffold, between which glittered the curved knife of the mandaia.

当他们接近波波罗广场的时候，人群愈来愈密了，在万头攒动的上空，可以看到两样东西，即方身尖顶的石塔，塔顶上有一个十字架，标明这是广场的中心和耸立在石塔前面，耸立在巴布诺街，高索街，立庇得街三条路的交叉口上的断头台的那两根直柱，在这两根直柱之间，悬挂着一把闪闪发光的弯刀。

Hai ragione rifiuti zero non è un termine da interpretare letteralmente ma l'abbiamo scritto l'obiettivo era L'ELIMINAZIONE DEL 90% DEL RIFIUTO e il riciclo del resto.

你为什么要浪费为零不是一个长期字面解释，但有书面的目标是取消90 ％的拒绝和回收的其余。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
