Achievements which are achieved by scientific research of predecessors are summarized. Some methods of how to generate self-similar process and a few means of estimating self-similar parameter are given. Self-similar traffics are generated by using of ON/OFF model with heavy-tailed distribution and results are given. The results of experiment accord with the theory. This identicalness indicates that the method of getting results by using of ON/OFF model is feasible.

本文总结了前人的研究成果，给出了几种常见产生自相似的方法和几种估计自相似参数的方法，并对ON/OFF模型叠加产生自相似业务进行了仿真实验，得到了实验结果，从实验结果可以看出，仿真结果和理论值比较接近，这说明利用ON/OFF模型叠加产生自相似业务是可行的。

The unit discharge of auditory neuron in the cortical AⅠ area was recorded with the extracellularly recording method. The character of ON-OFF responses induced by short pure tone and the influence of stimulating lateral amygdaloid nucleus on these responses and the tuning curves of the recorded neurons were examined.

在30只氨基甲酸乙酯麻醉的SD大鼠上记录神经元单位放电，观察短纯音诱发的皮层AⅠ区神经元ON-OFF反应的特性及电刺激杏仁外侧核(lateral amygdaloid nucleus， LA)对ON-OFF反应以及调谐曲线的影响。

The characteristics of on-off responses of medial geniculate body neurons to tone bursts of varying frequency, intensity and duration were affected by lateral amygdaloid nucleus stimulation, which was in form of altering the pattern of discharge or complete suppression. The effect also varied with the changes of the interval between amygdaloid stimulation and the tone bursts. The results of the present work show that LAm could modulate temporal processing of auditory information.

新西兰兔内膝体神经元的on-off反应与纯音刺激的强度、频率及作用时程有关；刺激边缘系统杏仁外侧核，可以抑制on-off反应，或是使on-off反应放电构型发生变化。on-off反应是神经元对声音信号作用时程及声音的起止进行编码的方式之一，LAm对on-off反应的影响表明，边缘系统杏仁体的活动可以调控听觉中枢对声音时间信息的编码。

This paper mainly consists of five parts. The Introduction mainly defines the scope and relative concepts, and covers the present situation of research about it. The first chapter traces the Seeing-off-poetry's cultural origin, classifies its emotion contents and artistic achievements, and differentiates the flows from the base of comprehensive reorganization of the Seeing-off-poetry from pre-Qin to latter-Han Dynasty. The second chapter studies its variations about styles, artistic expressions, and gentries' spirit features. And in this part we also discuss the reasons of Four-word-see-off-poetry's booming and its peculiarities in Jin Dynasty. The third chapter demonstrates the influence on Seeing-off-poetry in the Early and Glorious Ages of Tang Dynasty such as the construction ways, poetry images and emotion styles. The Appendix enumerates all the 465 Seeing-off poems' tittles, authors, their birth and dead time, writing time and sources of quotation one by one, so that all of them can be checked to prepare the investigation.
