摘要：作为一名以表演为主要艺能的演员，王萍多少有些与众不同之处。算起来，自1992年从江苏盐城鲁迅艺术学校毕业以后，王萍进入上海淮剧团已近十五年了。在这十五年的演艺生涯中，相对于在前台的角色演绎，似乎还是幕后独唱和伴唱的“戏份”更多些。这种情况，在其他年龄相当、演艺成熟的演员中，是不太多见的。

摘要：2005年7月30日，京剧《王子复仇记》在丹麦克隆城堡首演。演出开始前半个小时，排队等候进场的当地观众就已在古堡门前排起蜿蜒长龙很快，只能容纳500个座位的广场便被坐得满满当当。按当地的习惯，在演出进行中观众是不鼓掌的，然而，演员们的精彩表演居然使这个习惯改变了——两小时十五分的演出中，

摘要：Nickel-based layered double hydroxides(LDHs)are promising electrode materials in the fields of energy storage(supercapacitors)and conversion(urea oxidation).The rational construction of atomic and electronic structure is crucial for nickel-based LDHs to realize their satisfactory electrochemical ***,we report a facile,ecofriendly,one-step synthesis process to construct petal-like oxygen-deficient NiAl-LDH nanosheets for hybrid supercapacitors(HSCs)and urea oxidation reaction(UOR).The asprepared NiAl-LDH nanosheets with rich oxygen vacancies possess a large specific surface area of 216.6 m2 g^(-1) and a desirable electronic conductivity of 3.45×10^(–4)S cm^(-1) to deliver an ultra-high specific capacitance of 2801 F g^(-1)(700 C g^(-1))at 1 A g^(-1).Furthermore,high specific energy of 50.0 W h kg^(-1) at 400 W kg^(-1) and excellent cycle stability with 91%capacitance retention after 10,000 cycles are achieved by the NiAl-LDHs/CFP(carbon fiber paper)(+)//YP-80F(a commercial activated carbon)(–)***,NiAl-LDH nanosheets also work as an efficient electrocatalyst for UOR,which only requires 1.42 V *** hydrogen electrode to drive 10 mA cm^(–2) in 1 mol L^(-1) KOH with 0.33 mol L^(-1) *** remarkable performance is superior to most reported values of previous candidates owing to the thin structure of NiAl-LDH nanosheets for exposing more active sites and abundant oxygen *** addition,various reaction parameters are investigated to optimize the electrochemical *** general,this work paves a new way for the architecture of multifunctional nanostructured energy materials.

摘要：The effects of forging parameters on the deformation and microstructure distributions of as-forged straight spur gears wereinvestigated by finite element(FE)simulation and statistical analysis *** gear forging using the movable cavity die designwas investigated by integrating the FE method with the microstructure evolution models for AZ31B magnesium *** requiredinputs such as flow stress curves and microstructure evolution models,were obtained through the Gleeble thermal mechanical testingand quantitative metallography analysis *** simulation and experimental examination confirm that both thedeformation and microstructure are non-uniformly distributed in the as-forged *** deformation temperature orincreasing strain rate is beneficial to obtaining fine-grained microstructure but is harmful to the uniformity in deformation *** level of the non-uniformity results from the complex shape of gear and the friction between the billet and dies,which is closely associated with the characteristics of flow stress curve.

摘要：应丹麦爱森诺市政府和第24届“哈姆雷特之夏艺术节”组委会邀请,上海京剧院赴丹麦演出根据莎士比亚悲剧《啥姆雷特》改编的京剧《王子复仇记》,获得巨大成功,在当地刮起了一股中国传统文化“旋风”。

摘要：曲柄连杆滑块机构广泛应用于各行业,鉴于高转速、重负载等的工作要求,润滑油膜的影响在动力学分析中已经不可忽视。本文选择内燃机上的曲轴连杆活塞结构并简化实体模型,建立相应的运动微分方程组。运用VisualBasic6.0编制RungeKutta计算程序,求解各动力学参数,并结合机械设计理论求出润滑油膜作用下轴心的运动规律。本文提出的方法简化了计算,能够快速获得机构的运动规律。求解结果表明轴心的运动轨迹为一条闭合的曲线,曲轴的转动在波动中不断增大最后达到稳定,与实际相符合,为今后的研究提供了有效的思路。

摘要：以生活污水、含染发污水的混合污水及低浓度染发污水为对象,通过实验研究了SBR去除其COD、总磷、氨氮和总氮效能及活性污泥CAT活性变化特征,结果表明,染发污水对SBR法去除COD、总磷、氨氮影响不大,通过生物方法可以处理低浓度染发污水,染发污水COD、总磷、氨氮和总氮的去除效率可分别达到79.11%、92.16%、74.51%和55.93%,但由于染发污水的环状有机物有可能抑制了异养菌的作用,影响总氮的生物去除效果,使染发污水比生活污水的总氮去除率低14.70%;在反应器正常运行的典型周期内,3种污水的活性污泥CAT活性均呈先高后低的总体变化趋势,且活性污泥CAT活性分别依生活污水、混合污水、染发污水降低。

摘要：未来住宅的设计 ,不是简单地扩大面积 ,而要讲究住宅的“性能价格比” ,面积的增加要与功能的改善同步 ,套内平面空间关系的组合 ,硬件设置的配置 ,要兼顾住宅内外的综合环境 ,强调人与自然环境的和谐共生 ,提倡可持续发展 ,着眼解决人口老龄化的“长寿住宅” 。
