This has never been more so than in this era when politics has, in Jonathan Chait's recent portrait in The New Republic, become "an atavistic clash of partisan willpower," with Christian Right pitted against the Netroots Left in a polarized media environment defined by hyperbolic talk radio and the foolish excesses of the blogosphere.

这种事于今为烈,正如乔纳森·蔡特最近在《新共和国》中所描绘的那样,政治成了"返祖遗传式的党派意志力角逐",在夸大其词的广播谈话和博客流行的过分愚蠢的渲染而使媒体出现两极分化的氛围中,基督教右派被塑造成了与网根左翼不共戴天的对头。

An enhanced drain current model,along with an improved charge conservation capacitance model,is presented by the improvement of the channel length modulation and the hyperbolic tangent function coefficient based on the Materka model.

在Materka漏电流模型基础上,改进了沟道调制因子和饱和电压系数的建模方式,电容模型采用了改进的电荷守恒模型。

The results show that the flow stress decreases with increasing deforming temperature and increases with increasing strain rate. The flow stress of the alloy during hot compression deformation can be described by constitutive equation in hyperbolic sine function with a hot deformation activation energy of 196.27 kJ/mol. Partial recystallization takes place in the alloys deformed at a high temperature or at a low strain rate, and large number of dislocations and subgrains are observed in the alloy. The elongated grains observed in the samples coarsen with increasing temperature and decreasing strain rate. Correspondingly, the subgrain size increases and the dislocation density decreases. The main soften mechanism of the alloy transforms from dynamic recovery to dynamic recrystallization.

结果表明:Al-Cu-Mg-Ag耐热铝合金在热压缩变形中的流变应力随着温度的升高而减小,随着应变速率的增大而增大;该合金的热压缩变形流变应力行为可用双曲正弦形式的本构方程来描述,其变形激活能为196.27kJ/mol;在变形温度较高或应变速率较低的合金中发生部分再结晶,并且在合金组织中存在大量的位错和亚晶;随着温度的升高和应变速率的降低,合金中拉长的晶粒发生粗化,亚晶尺寸增大,位错密度减小,合金的主要软化机制逐步由动态回复转变为动态再结晶。
