There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.

因为实际面板在运作时就是闸极与汲极采用交流方式操作，所以接著探讨在闸极上与汲极上给予直流正、负偏压与交流正、负偏压应力测试，来比较非晶矽薄膜电晶体在闸极与汲极分别有偏压下，电晶体的最大衰退变化量，再加上闸极与汲极给予非同步偏压的状况，探讨此一非同步状况对於电晶体的影响，以及了解是哪些机制造成如此差异。

Aiming at this problem, we have carried out an experiment on seepage properties for mudstone and argillaceous rock, showed the test result, and analyzed the reason why both the β-factor and the acceleration coefficient are negative. In addition, mistakes often made by some researchers about positive or negative signs before the non-Darcy β-factor were pointed out.

指出一些文献在引用Forchheimer关系时出现的非Darcy流β因子前正负号的错误，给出了非Darcy流β因子和加速度系数出现负值的泥岩和砂质泥岩试样全应力－应变过程中渗透特性试验结果，并对其原因进行了粗浅的分析。

反之为负。例如：在X反方向的平面里，XY，XZ的值就为负。

However, obviously, his attitude to life is not purely sensory, autistic, negative or cynical, even not neutral. At least, according to the painter's statement, the motivation of the concern is "re-propose the issue of interaction between people and society and the new objective for reflection", to show an ideal of "overcome loneliness, overcome negative, overcome impetuousness."(Deng Jianjin's Readme). I think basing on this starting point for thinking, he keeps the proper distance with the new generation art whose attitude to life is straightforward, graphic, artificial and evasive.

但很明显，他对生活的态度不是纯感官性的、自闭的、消极的或泼皮式的，甚至也不是中性化的，至少，按照作者自己的说法，这种关注的动机是为了"重新提出人与现实社会的感应问题和新的反思对象"，为了展示一种"战胜孤独、战胜消极、战胜浮躁"的理想化的东西，我想，正是在这个思维起点上，他与那些平铺直叙、图解化、矫饰的逃避式地对待生活的新生代艺术保持了应有的距离。
