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。

A selective and mild PS-DIB/ionic-liquid immobilized 2, 2, 6, 6-tetramethyl-piperidin-4-ol-N-oxyl catalytic oxidation procedure of alcohols to the corresponding aldehydes and ketones in ionic liquid BF4 at room temperature was developed. The oxidant PS-DIB was prepared via the iodation and acetylation of polystyrene resin. For the preparation of the ionic-liquid immobilized TeMPO catalyst, 4-(2, 2, 6, 6-Tetramethyl-1-oxyl-4-piperidoxyl)butyl bromide was first synthesized from TeMPO and 1, 4-dibromobutane.

This finding is emphasized in a press release from Novartis, which states that there were 30% fewer distant recurrences with letrozole than with tamoxifen (87 vs 125 patients) and then explains that distant recurrences increase the likelihood of death from the disease."Avoiding distant metastases in early breast cancer is very important, because we know that this type of recurrence significantly worsens the prognosis for these women," Dr Mauriac is quoted as saying. Letrozole "may be beneficial in reducing early relapse," he adds.

在一项来自诺华药厂的新闻稿中强调这项发现，他们宣称使用letrozole相较於tamoxifen，发生远端转移的机率下降了30%（87位相较於125位病患），且接著解释远端再发会增加死於这个疾病的可能性；避免远端再发对早期乳癌来说是非常重要的，因为我们知道这种形式的再发显著地恶化这些妇女的预后；他附带表示，letrozole在降低早期再发上可能是具有好处的。

Wood could be liquefied into soluble reactive intermediates, which could further reactedwith phenol or by themselves. Phenolation and recondensation were a pair of competingreactions. Decomposition, phenolation and recondensation dominated the whole liquefactiondynamic process and determined the structural characteristics of liquefied wood.
