It has been proved by previous studies that peripheral nerve injury can induce a series of changes of expression of some neural active material and their receptors either in the somata or in the terminals of the damaged primary afferent neurons and motoneurons. These changes may reflect a re-ordering of metabolic priorities so that the synthesis of trophic factors or growth-associated proteins augmented while that of neurotransmitter-related proteins decreased.

以往的研究表明，周围神经损伤能够引起受损神经元(包括初级传入神经元和运动神经元)的胞体或终末内某些神经活性物质及其受体的表达发生一系列变化，其中与神经生长和营养有关的物质常发生上调，而与神经传递有关的物质则发生下调；与此同时，受损神经元的周围常伴随发生胶质反应及神经胶质增生等变化。

Artificial neural network is a fast developing intercrossed subject. The theory of ANN make the transmitting of large information and complex calculation possible. ANN is not only a highly non-linear dynamics system but also a self-organization and self-improvement system. In the early 1980's, the appearance of ANN dramatically promote the primary research on understanding and intelligence of human-being as well as the computer industry.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
