5C_1化学的新结构单元甲酸甲酯显示文摘0 前言C_1 化学涉及一碳到多碳的转化,C_1 化学品可从煤及其它碳质材料来的合成气生产。近年因石油危机,C_1 化学普遍受到重视。合成气直接生产化学品虽好但选择性差、条件苛刻。所以一般认为先台成甲醇这种便于运输存贮的物质,再合成化学品更可取。因此,甲醇是 C_1化学的结构单元。甲酸甲酯也能起到这种结构单元作用,不但因其贮运便利,可大规模生产。J.S.Lee J.C.KIM Y.G.KIM 张剑锋 1990煤炭综合利用译丛1990,13,4:0
6Microstructural Characteristics of Underwater Shock Consolidated Aluminum Composites显示文摘Metal matrix composites (MMCs) offer extra strength and high temperature capabilities in comparison with unreinforced metals. Aluminum composites possess higher stiffness, strength, fatigue properties and low weight advantages.Carbon fiber reinforced Al composites (Al-Cf) and silicon carbide particulate reinforced Al composites (Al-SiCp) were shock densified using axisymmetric assemblies for underwater explosions. Unidirectional planar shock waves were applied to obtain uniform consolidation of the composites. The energy generator was a high explosive of 6.9 km/s detonation velocity. Irregular morphological powders of Al were the base material. The reinforcement ratio was 15 Vol. pct for Al-Cf composites and 30 Vol. pct for Al-SiCp composites. The microstructural and the strength characteristics of the shock consolidated Al composites are reported.K.Raghukandan K.Hokamoto J.S.Lee A.Chiba B.C.Pai 2003Journal of Materials Science & Technology2003,19,4:0

8Wireless actuation and control of ionic polymer-metal composite actuator using a microwave link显示文摘The ionic polymer–metal composite(IPMC),a type of electroactive polymer(EAP)actuator,has created a unique opportunity to design robots that mimic the motion of biological systems due to its soft structure and operation at a low voltage.Although this polymer actuator has strong potential for a next-generation artificial muscle actuator,it has been observed by many researchers that supplying actuation voltages in multiple locations is challenging.In robotic applications,a tethered operation is prohibited and the battery weight can be critical for actual implementation.In this research,the remote unit can provide necessary power and control signals to the target mobile robot units actuated by IPMCs.This research addresses a novel approach of using a wireless power link between the IPMC and a remote unit using microstrip patch antennas designed on the electrode surface of the IPMC for transmitting the power.Frequency modulation of the microwave is proposed to selectively actuate a particular portion of the IPMC where the matching patch antenna pattern is located.This approach can be especially useful for long-term operation of small-scale locomotion units and avoids problems caused by complex internal wiring often observed in various types of biologically inspired robots.J.S.Lee W.Yim C.Bae K.J.Kim 2012International Journal of Smart and Nano Materials2012,3,4:0
