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.

You Call It Love 歌词 You call it love There are things I need to say About the way I feel When your arms are all around me You call it love Words I'd heard that sound so fine Meaningless each time Till you came and found me See the ground is slowly turning dizzily, easily Feel the way my heart is burning secretly inside of me You call it love All the wishes in my mind Soared into the skies Where reflected in my own eyes You say it's love variations on a theme Love was just a dream Memories of past sighs See your love is always round me Everywhere in the air New sensations now surround me Ocean wide deep inside You call it love All my days past close to you Grey skies turn to blue And the sun shines all around me You call it love It's a phrase that people say Each and every day Real love is hard to find though See the ground is slowly turning dizzily easily Feel the way my heart is burning from your touch secretly You call it love Now I know it's so much more Being close to you Makes this feeling new that you call it love.

你称之为爱情有些事情我必须说出来关于我现在的心情当你的手臂环抱着我你称之为爱情我听到的话是如此动听但每一次都是毫无意义直到你走来找到我看到地面慢慢的变化头晕目眩的，简单容易的我的感觉是我的心在燃烧秘密的在我心里你称之为爱情所有的愿望在我心中飞向天空在我的眼睛里反射出来你称之为爱情主题变奏了爱情只是一个梦想回忆过去的叹息你的爱始终都在在空气的每个角落现在新的感觉包围着我像海洋般深邃宽阔的在我心里你称之为爱情过去所有的开进你的日子灰色的天空变成了蓝色所有的阳光都围绕着我你称之为爱情那是人们常说的一个句子每天每时真正的爱情是很难寻找的看着地面慢慢的转向头晕目眩的，简单容易的，悄悄地觉得我的心在燃烧因为你的触摸你称之为爱情现在我知道了就是如此当靠近你的时候又有了新的感觉你称之为爱情

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase （congenital cal1 phase, CCP, 0~12 day of age）, the juveniles only produce single syllable with short syllable length. The second phase（blank-model-forming phase,BMFP, 13~30 day of age） is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase （call-model-forming phase,CMFP, 31~45 day of age）, the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase （call-feedback-learning phase,CFLP, 46~90 day of age）. The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase （excellent call phase,ECP, after 91 d）, vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.
