摘要：A novel design of multimode light power splitter is proposed and fabricated by using secondary asymmet- ric Y branches. An almost equMly divided output among output terminals is obtained experimentally. Maskless laser direct writing technique is applied in the fabrication process to facilitate the formation of power splitters by ultraviolet curable polymer. The analysis of the performances of both four-port and eight-port devices shows that these two dividers obtain a power splitting uniformity of more than 95%.

摘要：High-voltage nMOS devices are fabricated successfully and the key technology parameters of the process are optimized by TCAD software. Experiment results show that the device＇s breakdown voltage is 114V, the threshold voltage and maximum driven ability are 1.02V and 7.5mA（W/L = 50）, respectively. Experimental results and simulation ones are compared carefully and a way to improve the breakdown performance is proposed.

摘要：Co nanostructure tetradecahedron shape like were prepared via a simple solvothermal route. The shape and size of Co nanopolyhedron were tuned by changing the volume composition of the solvents and the synthesis temperature. Phase purity was confirmed by X-ray diffraction （XRD） and crystal size was determined by scanning electron microscopy （SEM）. The magnetic hysteresis loops of the polyhedron wareneasured using a SQUID magnetometer at 5 and 300 K. The results show ferromagnetic characteristics with coercivities of 22 and 15 Oe, respectively.

摘要：20世纪90年代以前,中国建筑设计圈子存在着两种思潮,一种是如何继承传统,如何将中国的传统文化在现代设计中发扬光大;另一种,是如何把西方的设计理论及设计方法运用到中国的建筑设计中来。在这两种思潮中的纠结,在客观上使中国建筑师特别没有自信;那个时期的设计作品,要么存在着模仿某些西方建筑作品的明显痕迹,要么直接带有中国传统建筑的直白的语汇相符号。1990年代后期,中国建筑界发生了很大的变化。一些年轻的建筑师,关注到＂建构＂理论对20世纪的建造历史的总结,在这一理论的鼓舞下他们回到了建筑本质问题＂基本建造＂的思考上.
