查询词典 mechanisms

Several common degradation phenomena were summarized from some recent typical research work on the reliability of low-temperature processed poly-silicon thin film transistors, which includes self-heating, hot carriers and negative gate bias temperature instability. Degradation mechanisms and models are presented as well as conclusions of their influences on various device parameters and typical stress conditions.

结合近几年来国际上对于低温多晶硅薄膜晶体管器件可命性开展的一些有代表性的研究工作，对其中几种常见的退化现象：自加热、热载流子和负偏置温度不稳定性做了分析和归纳，介绍了其退化机制及退化模型，并总结了它们在一般情况下对器件性能的影响及各自的典型应力条件。

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。

In summary, our results indicate that hypohidrosis is a frequent adverse effect in children with topiramate therapy. Younger age and hot weather rather than drug dosage are independent risk factors for topiramate-associated hypohidrosis. The resultes also rule out the possibility that topiramate act on its known mechanisms of action, such as potentiating GABA activity at GABAA receptors and antagonizing the AMPA/KA subtype of glutamate receptor in the secretory cells of sweat glands to inhibit sweat secretion. Our data also suggest that topiramate impairs sudomotor function in mice and leads to a significant reduction in AQP5 expression in sweat glands of anhidrotic mice, thus raising the possibility that dysregulation of AQP5 may contribute to topiramate related hypohidrosis. CA inhibition may not be an important contributor since CA II expression and CA activity was intact in anhidrotic mice treated with topiramate.

综合全部实验结果，本研究提示：夏季和低龄是托吡酯引起泌汗障碍的主要危险因素，而托吡酯剂量对泌汗功能的影响较小；托吡酯可以抑制小鼠汗液的分泌，小鼠的年龄并不影响这种抑制作用，但托吡酯对小鼠体温无明显影响；托吡酯并不是通过对GABAA受体及AMPA和KA两种谷氨酸受体亚型的作用而在汗腺分泌细胞抑制泌汗；托吡酯不影响汗腺形态及Na，K-ATP酶活性；汗腺分泌细胞的AQP5功能失调可能与托吡酯引起的泌汗障碍密切相关，而碳酸酐酶抑制作用并不是泌汗功能损害的主要原因。
