The structure of C50H10 is identified through NMR, mass spectrometry, and IR and Raman spectroscopy as a D5h symmetric closed-cage molecule with five pairs of fused pentagons stabilized by ten hydrogen atoms. UV/Vis and fluorescence spectrometric analyses disclose its optical properties as comparable with those of its chloride cousin (C50Cl10). Cyclic and square-wave voltammograms reveal that the first reduction potential of C50H10 is more negative than that of C50Cl10 as well as C60, with implications for the utilization of C50H10 as a promising electron acceptor for photovoltaic applications.973 projects 2011CB935901 NSFC 21031004 21021061 2077310

The Control Technology of Three-Phase Unbalance Load in Low Voltage Distribution Networks Based on Coordinated Controlled SVGs

针对集中式静止无功发生器(SVG)补偿系统补偿效果单一、不含通信功能的分布式SVG补偿系统补偿容量不能智能分配的问题,提出基于协调控制SVG的低压配网三相负荷不平衡补偿系统。该补偿系统引入通信总线,采用协调控制方法,使低压线路下游接入的SVG可利用补偿其下游不平衡电流后的剩余容量,依次对上游SVG不足容量进行补偿,该补偿形成的逆向潮流可进一步减轻各节点的低电压问题。该补偿系统既可以充分利用各SVG的补偿容量,同时也综合地解决了配电变压器电流不平衡、节点低电压等问题。在Matlab/Simulink数字仿真软件下进行了该补偿系统补偿效果的仿真,结果证明了该补偿系统的准确性。在四种不同负荷情况下比较采用四种不同补偿系统的低压配网配电变压器二次侧不平衡电流和各节点电压降,结果表明该补偿系统的效果最佳

BnGID1基因过量表达对甘蓝型油菜矮化突变体NDF-1株高的恢复

在正常株高油菜中克隆了与拟南芥矮化突变相关基因AtGID1同源的BnGID1基因全长cDNA目的片段,将其正向插入表达载体pFGC5941上的CaMV35S启动子下游,构成该基因过量表达载体pFGC5941-BnGID1.经根癌农杆菌介导,导入甘蓝型油菜矮化突变体NDF-1基因组,通过PCR及半定量RT-PCR检测,确定得到抗性转基因植株23株.移至大田生长,观察结果显示,转基因植株明显高于对照矮化突变体NDF-1,平均高出49.05cm.结果表明,BnGID1基因过量表达能够使甘蓝型油菜矮化突变体NDF-1株高得到较大程度的恢复.图7表2参1
