First of all , it is seen in Zhang Wei"s long writing that continuous changes occurs with the following era contexts which is shown. First, the gradual desalinization of " earth image " on the space," earth " is not only a creation in Zhang Wei"s novel, but the main source of the poesy of its works. It declines after " September fable ", not only indicating Zhang Wei "s decay of poesy of the novel, but also reflecting the disobeyed pross of light appear contemporary China social urbanization and common customs to . Second, the change of " writing subject projection " in the spiritual meaning, Its characteristic displayed by the reduction of image of spokesman as write thought representation .and on the other side represent" person who want more that resist actively " which also shows contemporary intellectual predicament and adjustment of value. Third, in " changeable and separate characteristics in the stylistics ",It changes " epic body " of" Ancient ship "," body not mythical " to " September fable "," pour out body " of" Bai Hui "" Family "," the discipline spreads the body "of Book of other provinces"," lie body " of" Can not recall the hollyhock ". Its constant changes persuing of recreation and sports, has entered into the different book mode and narration of different class gradually too.

首先，张炜的长篇写作中可以看出一种跟随时代语境而不断发生的变化，这表现在：一是空间上的"大地意象"的渐趋淡化，"大地"不但是张炜小说中的一个创造，而且也是其作品的诗意的主要源泉，它在《九月寓言》之后的衰退，不但表明了张炜小说中诗意的衰减，而同时也反照出当代中国社会城市化和世俗化进程的不可违拗；二是精神意义上的"写作主体投影"的变化，其特征主要表现为作为作家思想代言者的"正面的知识者"形象的弱化，代表其另一面的"积极反抗的多欲者"的凸显，这也显示了当代知识分子价值的困境与调整；三是在"文体上的多变与另类化"，由《古船》的"史诗体"，到《九月寓言》的"神话体"，再到《柏慧》、《家族》的"倾诉体"，《外省书》的"纪传体"，《能不忆蜀葵》的"诳语体"，其文体不断求变，也逐渐走入了异书模式和另类叙述。

Methods: Polytetrafluoroethylene and polypropylene film electrets were prepared by constant voltage corona charging at room temperatures. The charge-store stability of PTFE and PP were studied by measuring isothermal surface potential decay after different dose of ultraviolet radiation.

It is this self-interest, this constant self-advancement, that makes the mind petty; and though its activity be extensive, though it be occupied with politics science, art, research, or what you will, there is a narrowing down of thinking, a shallowness that brings about deterioration, decay.

正是这种自我利益、持续的自我晋升使得头脑变得渺小；尽管它的活动是广大的，尽管它被政治、科学、艺术、研究或者你想要的填满了，但它仍然限制思考，它的浅陋会带来退化。

After the application of 100μ M linopirdine to OHCs, the peak K+ current was reversibly blocked and the late K+ current was partly reduced. In addition, the decay time constant of the TEA-sensitive K+ current was prolonged in the presence of 100μ M linopirdine. The inward current in OHCs was totally inhibited after the superfusion of 100μ M and 200μ M linopirdine respectively.

结果发现，在正常细胞外液中，单离外毛细胞可记录到四乙基二乙胺敏感的外向性钾电流和静息膜电位附近激活的内向性钾电流（ the K+ current activated at negative potential， IKn）两种钾电流，而单离Deiters细胞中只记录到外向整流性钾电流。
