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.

Finally, the condition examining and schema decomposition algorithm are given.Fourthly, The definitions of elementary merge dependency set and minimum elementary merge dependency set are put forward. The weak leftside conflict and weak rightside conflict in the minimum elementary merge dependency set are defined. The conclusion that when the minimum elementary merge dependency set has weak left side conflicts or weak right side conflict is reached, The decomposition meeting PEK isα-cyclic is given. The algorithms of calculating the minimum elementary merge dependency set and examining the conflicts are given.

The study was aided by the Ailuropoda Fund and designed on account of the Chengdu zoo' s topic that the Detection of the feline distemper' s serum antibody and the foundation of its immune programme about the grow wild feline animal such as Panthera pardus L, et al. The study regarded the attenuated feline panleukopenia virus as the diagnostic antigen which was isolated from the tri-combinant vaccine of Feline rhinotracheitis virus, calicivirus and panleukopenia virus . According to the tesults of Virus Physical and Chemical Character Detection, Agar Diffusion Reaction and Virion Shape Electron Microscope Observation, it was affirmed that the virion which was isolated from the tri-combinant vaccine was feline panleukopenia virus .

本研究从猫瘟热病毒、猫鼻气管炎病毒、猫鼻结膜炎病毒三联弱毒活疫苗中分离猫瘟热病毒弱毒株，通过对分离株进行病毒理化特性检测、双向琼脂扩散试验检测和病毒粒子形态电镜观察，最终确认从三联弱毒疫苗中分离到猫瘟热病毒，并以此分离株作为诊断抗原。

Results There were 176 eyes （55％） in hypemetropic amblyopia cases in ametropic amblyopia,96 eyes（30％） in mixed amblyopia cases in ametropic amblyopia.There were similar results for therapy in two groups.

To explore the properties of the cortical response to visual coherent motion and reveal the possible neural mechanism of cortical deficit of visual motion perception in anisometropic amblyopia so that we can diagnosis and treat it earlier and specifically.

以期能进一步揭示屈光参差性弱视视觉运动功能缺陷的可能皮层机制，为早期发现和早期治疗潜在的弱视病人提供理论依据并帮助临床根据弱视不同的脑功能区损害特点进行有针对性的诊疗。材料与方法1。

Results:1. In the central region the N_1-P and P-N_2 amplitudes of mfVEP of the strabismic amblyopic and anisometropic amblyopic eyes were reduced compared with the fellow eyes and the normal eyes.

结果： 1。斜视性弱视和屈光参差性弱视mfVFP的N_1-P振幅和P-N_2振幅在中央区较对侧眼和正常对照组降低；屈光不正性弱视N_1-P振幅和P-N_2振幅在中央区较正常对照眼降低，其差异均有统计学意义。

The fEPSP response evoked in one pathway was small, usually 20–30% of the maximu, whereas a large response, usually 80–90% of the maximum, was evoked in the strong pathway. After recording of the baseline fEPSP evoked at 0.033 Hz, LTP of the weak pathway could be associatively induced by paired stimulation of the weak and strong pathways 100 times at 6 sec intervals, with stimulation of the weak pathway preceded 3–10 msec.

在记录以0.033Hz所引发基础的兴奋性突触后电位之后，在弱的路径上可以因配合弱与强的刺激路径而引发出相关性长期增益（每六秒一次共100次，弱的刺激路径在强的刺激路径之前 3-10 ms），然而当在两个路径之间的配合时间差大於10 ms时即无法形成相关性长期增益，此类型长期增益的引发是需要依赖活化NMDA接受器的，因为给予50 mM的D，L-AP5可以阻断相关性长期增益的引发（兴奋性突触后电位为原来的105±6﹪；n=6）。
