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.

If someone alive today has no knowledge of the pole shift what happens if they die before the pole shift - do they suddenly became aware of what is about to take place on earth when they die and are discarnate, are they told by spirit guides and can they therefore hang around to watch loved ones during the pole shift.

如果今天活著的某人知道极移发生的情况，而在极移之前他就死了，那他在死亡和失去形体的时候，可以突然意识到在地球上将要发生的事情吗？

XRD showed hexagonal wurtzite structure. Room-temperature PL spectra of perfectly overcoated CdSe/ZnS only showed a narrow band edge emission. Emission peak was great red-shifted relative to absorption and the shift increases as the size decreases. The size-dependence of shift could be explained very well in terms of excition fine-structure model and stress at interface owing to lattice mismatch contributes to the shift between CdSe and CdSe/ZnS with the same size.

结果显示表面修饰完善的样品的荧光光谱只有一个窄而强的带边发射；所有样品的荧光峰相对于1S-1S吸收峰有较大的红移，并且移动量随尺寸的减小而增加，利用激子的精细结构模型很好地解释了红移量和尺寸的关系；核／壳结构的样品的吸收峰和荧光峰相对于同尺寸的单量子点也有红移现象，这是由于CdSe和ZnS的晶格失配在界面上产生压力造成的。

Adopt the practice of half an year, daystart nurses quality gets rising. 2 joining a class is so guide responsibility nurse and whole family nurse and evening shift nurse to undertake collective by sister perambulatory, evening shift nurse pursues the patient's condition of bed introduction patient, this kind of hand over to the next shift took a nurse seriously only between have sex, and the participation that ignored a patient, affected the result that have sex.

通过半年的实践，晨间护理质量得到提高。2交接班原来是由护士长带领责任护士及全科护士和夜班护士进行集体巡视，夜班护士逐床介绍病人的病情，这种交班只重视了护士间的交接，而忽视了病人的参和，影响了交接的效果。
