The 21st century is a century of life science,the mathematical biology advanced rapidly, and the study in determinate system is perfect. In face,the species ecology systems are often subject to ,some uncertain factors,white noise,whether the presence of such noise affects these results that we have obtained has received exten sive attention ,which makes the study about stochastic system more and more important.

21世纪是生命科学的世纪，生物数学的发展突飞猛进，百花争妍，其中对确定性系统的研究已经较为完善，而实际上的种群系统常受到一些不确定性因素的干扰，即白噪声的干扰，研究白噪声的存在是否影响种群生态系统以及是否使原有的结果发生变化已受到广泛的关注，这就使对随机系统的研究显得尤为重要。

本研究结果证明：鼠脑无名质区破坏引起的学习、记忆障碍，是由于中枢胆碱能细胞损害，引起胆碱能上行投射系统顺行性变性，致使大脑皮层失胆碱能支配，发生胆碱能系统功能低下所致。

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。
