A simple （2×2） pixelated flexible infrared nanosensor array based on carbon nanoparticles （CNPs） was fabricated through a simple and low-cost flame method. By integrated with a micro controller unit, the sensor array could detect power density of incident infrared light in real-time. The mechanism for the superior infrared sensing property of the flexible sensor array based on CNP was also studied in detail in this work.

俄罗斯宪法法院与人权保障

俄罗斯东欧中亚研究 2007年第1期 22-26页

作者：尤晓红中国人民大学

在当代的俄罗斯,宪法法院在人权保障方面所发挥的作用是不可替代的。国家与个人关系的重构为宪法法院保障人权奠定了基础。宪法诉愿是公民启动宪法诉讼程序的制度依据,而对社会经济权利的关注则是当下俄罗斯宪法法院保障人权的鲜明特征。

针对闭孔泡沫铝制备过程中孔结构控制问题,提出了一种基于半固态成形技术的两步法泡沫铝制备新工艺[即先用半固态成形技术制备预制体,再用二次加热发泡法(Semi-solid foaming)]-SSF法发泡。就SSF法的基本工艺参数对发泡过程和孔结构的影响以及工艺参数的优化等问题进行了研究。结果表明,SSF法可以控制TiH2的分解时间,实现二次发泡工艺,获得孔结构较均匀、孔隙率为74.6%、孔径范围为2.1～3.2mm(平均值为2.3mm)、平均圆度为0.812的泡沫铝硅合金。试验条件下的最佳工艺参数:搅拌温度为580℃,搅拌时间为0.5min,搅拌速度为1200r/min,二次发泡炉温为720℃,加热时间为15min。

利用Dynaform软件对某轿车行李箱盖外板成型过程进行了模拟研究,通过正交试验对影响冲压成型的压边力、摩擦因数、凸凹模间隙、拉延筋高度等工艺参数进行了优化组合,对4个参数对成型结果的影响程度进行了分析,从而可知影响程度最大的参数为压边力和摩擦因数。结合回归分析方法探讨了压边力和摩擦因数对成型结果的影响规律,并将仿真结果与实际生产零件进行了对比。结果表明,模拟得到的最佳工艺参数与实际生产中所用工艺参数基本相同,成型部分仿真结果与实体零件的数据非常接近,变化趋势相同。
