1八乙墓卟啉和四苯基卟啉合钌(Ⅱ)及锇(Ⅱ)的二氧加合物的红外光谱显示文摘OEP(八乙基卟啉阴离子)和TPP(四苯基卟啉阴离子)合钌(Ⅱ)和锇(Ⅱ)的二氧加合物由matrix分离技术得到(T=20-43K,P=10-5-10-6torr).为了确定v(O2)带的归属应用了同位素取代法16O2/18O2.IR谱说明对于钌的两种加合物(指OEP和TPP)都有两种异构体,其V(16O2)频率为:Ru(OEP)O2,1141和1103cm-1;Ru(TPP)O2,1167和1114cm-1.Os(TPP)O2只生成一种异构体,v(16O2)=1090cm-1,异构体v(16O2):[Ru(OEP)O2],1141cm-1,[Ru(TPP)O2],1167cm-1,这些加合物约在100K时分解,它们的结构指定为endon,而异构体[Ru(OEP)O2],1103cm-1,[Ru(TPP)O2],1114cm-1和[Os(TPP)O2],1090cm-1,在240—270K分解,它们的结构指定为桥联二聚体.在加合物中,将OEP换成TPP引起的钌加合物v(O2)频率的改变比铁和钴加合物更大.v(O2)相对强度的变化顺序为:Fe(Ⅱ)→Ru(Ⅱ)→Os(Ⅱ).Lewandowski, W.(Institute of General Chemistry. warsaw Agricultural University.SGGW. 02-528 Warsaw, Rakowiecka 26/30, Poland)(Matrix isolation IR spectra were obtained during author’s stay at the Marquette University, Milwaukee, WI 53233(USA). 1994无机化学学报1994,10,1:4
2A Variational Finite Element Model for Large-Eddy Simulations of Turbulent Flows显示文摘The authors introduce a new Large Eddy Simulation model in a channel,based on the projection on finite element spaces as filtering operation in its variational form,for a given triangulation{Th}h>0.The eddy viscosity is expressed in terms of the friction velocity in the boundary layer due to the wall,and is of a standard sub grid-model form outside the boundary layer.The mixing length scale is locally equal to the grid size.The computational domain is the channel without the linear sub-layer of the boundary layer.The no-slip boundary condition(or BC for short)is replaced by a Navier(BC)at the computational wall.Considering the steady state case,the authors show that the variational finite element model they have introduced,has a solution(vh,ph)h>0that converges to a solution of the steady state Navier-Stokes equation with Navier BC.Toma's Chac'on REBOLLO Roger LEWANDOWSKI 2013Chinese Annals of Mathematics,Series B2013,34,5:2
3轮铲式挖掘机新一代驾驶室隔震系统的优化显示文摘提出新一代驾驶室计算机辅助设计的一些观点,重点关注驾驶室隔振系统的原始设计方案,它由挖掘悬臂连同驾驶室悬臂组成.用有限元法对驾驶室动态特性进行了分析,在虚拟模型数值分析的基础上形成一个方案,随后建立一个带有隔振系统的驾驶室原型样模,实体振动测量提供了非常令人满意的结果.Eugeniusz Rusi■ski Tadeusz Lewandowski Wiktor S■omski 吕新生 2005工程设计学报2005,12,3:2
