摘要：In 1923, Wu Ruiyan, a schoolgirl at the Beijing People＇s Art Drama School, starred in a play titled Hero and Beauty, written by Chert Dabei. This was the first joint performance of male and female performers in the history of Chinese drama. The incident immediately triggered a debate in the Morning Newspaper Supplement between a group of middle-class intellectuals concerning ＂female involvement in art performances＂. This paper sees the boom in female participation in politics in the 1920s, as well as the ＂improvement in traditional drama＂ during the early republican period in China as the reasons behind the discussion. This incident shows how the New Cultural Movement shaped intellectuals＇ views on females and art performances.

摘要：为使产品与人体的接触面形态具有良好的人机工程学性能,通过测试接触压力分布数据进行映射计算,获得接触面曲面形态。利用压力分布测试仪测得产品与使用者的持续接触压力分布数据,在压力大小和接触面的非均匀有理B样条曲面模型的控制点坐标之间建立映射函数,设计了七种数据映射算法模型,将压力分布数据映射为不同的接触面形态。对比产品接触面形态的统计数据,进行了映射算法的误差分析,比较了各映射模型的造型能力和造型质量。为提高人机接触曲面的设计质量提供了理性化与高效的设计方法。

摘要：随着绿色航空发展,为了能在设计阶段快速获得涵道风扇气动性能参数和非定常流场特征,有必要开发一种高效的数值求解方法。基于小型电推进风扇内流弱可压和尾迹耗散特性,本文将转子和涵道的面元与尾迹涡粒子耦合,使用面元法求解固壁流场,使用涡量输运方程求解远场尾迹传播特征,克服了有限体积法尾迹耗散快的问题。研究表明,本文发展的面元-涡粒子耦合方法对涵道风扇叶表压力与有限体积法趋势一致,整体推力误差为7.83%,能满足工程快速预测需求。本文发展的高效非定常计算方法的尾迹计算数值耗散低,能揭示更为复杂的非定常流动现象,仿真结果显示风扇涵道对尾迹发展有明显约束,而当尾迹传播至外部时,涡量呈现出明显的收缩和对称分布特征。在计算效率方面,本文发展的耦合方法非定常计算效率高,计算相同非定常时间步耗时仅为有限体积法的1/6,具有潜在的涵道动力非定常设计应用价值。

摘要：对Zr-Sn-Nb合金在α+β两相区温度下不同工艺热处理后所得样品,在360℃/18.6 MPa纯水环境中进行均匀腐蚀试验,并采用扫描电子显微镜(SEM)观察样品微观形貌、聚焦离子束(FIB)和原子力显微镜(AFM)分析腐蚀后样品表面氧化膜。结果表明,Zr-Sn-Nb合金在α+β两相区温度下热处理时,锆合金中会形成条带状β-Zr第二相,再经过α相区温度最终退火后,β-Zr区域会分解为α-Zr和第二相粒子;经α相区最终退火的样品,在360℃/18.6 MPa纯水中的耐腐蚀性能优于未经最终退火的样品;未退火样品中条带状β-Zr第二相区域的氧化膜较α-Zr基体的氧化膜厚,而经过α相区温度退火后β-Zr发生分解,该区域的腐蚀氧化膜出现凹陷。
