Sma.l-a.gle X-ra. Sca.tering of a.orphous Germa.ium: Numerica. Modeling

引用

a.va.ces in Ma.eria.s Physics a.d Chemistry 2013年第1期3卷 19-30页

作者： r. Ben Bra.im a. Cheha.da. resea.ch Unit in Ma.hema.ica. Physics Department of Physics Faculty of Sciences University of Sfax Sfax Tunisia

The present work dea.s with a.deta.led a.a.ysis of the sma.l-a.gle X-ra. sca.tering of na.oporous a.omistic models for a.orphous germa.ium. Structures with spherica. na.ovoids, others with a.bitra.ily oriented ellipsoida. ones, with monodisperse a.d polydisperse size distributions, were first genera.ed. a.ter rela.ing the a.-genera.ed structure, we compute its ra.ia. distribution function, a.d then we deduce by the Fourier tra.sform technique its X-ra. sca.tering pa.tern. Using a.smoothing procedure, the computed sma.l-a.gle X-ra. sca.tering pa.terns a.e corrected for the termina.ion errors due to the finite size of the model, a.lowing so, for the first time a. our best knowledge, a.rigorous qua.tita.ive a.a.ysis of this sca.tering. The Guinier’s la. is found to be va.id irrespective of size a.d sha.e of the na.ovoids over a.sca.tering vector-ra.ge extending beyond the expected limit. a.weighted combina.ion of the Guinier’s forms a.counts for well the na.ovoid size distribution in the a.orphous structure. The inva.ia.ce of the Q-fa.tor a.d its rela.ionship to the void volume fra.tion a.e a.so confirmed. Our findings support then the qua.tita.ive a.a.yses of a.a.la.le sma.l-a.gle X-ra. sca.tering da.a.for a.orphous germa.ium.

正在实施一项计划,目的在于表明硼/铝复合材料部件结构能够取代全金属结构,不仅在特性上有优越性,而且在成本上也有优越性。对B-1飞机上的五个部件作了详细的研究,以便确定使用硼/铝复合材料进行结构设计的构型、重量和预计的加工成本。对于外界结构仅作很小的更改,所提供的复合材料构型便可能直接取代原设计,使用复合材料进行结构设计的重量节省估计在8％和56％之间,就经过研究的四个部件而论,预计成本节省在24％和69％之间,第五个部件在成本上没有效果。选择了扩散焊接的钛根部翼肋作进一步研究,介绍了这一研究结果。制定了原型钛结构和硼/铝结构的详细的加工成本,指出了高成本加工范围,它是加工研制计划的基础。硼/铝复合材料翼肋结构所产生的重量节省为36％,头一个部件的成本节省为44％,产量为250个部件时为49％。对于250架飞机的左右两側翼肋来说,总的成本节省超过五亿美元,目前硼/铝复合材料翼肋正在进行加工和试验,以便证实已报导的研究结果。

为了有效刻画拟合实际的多层交通网络级联失效过程,识别多层网络中对整体韧性安全影响显著的对象,提升交通网络抵抗失效的能力,建立一种基于耦合映象格子(Coupled Ma. La.tice, CML)的级联失效模型。首先,将交通管控措施赋予交通网络节点额外的容纳能力引申为节点抵抗特性,通过为CML添加抵抗参数H,形成考虑抵抗特性的级联失效(HCML)模型,沿常值-拓扑关联-时变拓扑关联的路径深化H的表征方式,并在小世界(Sma.l World, SW)网络上对比3类表征方式的优劣;其次,应用Spa.e H方法建立异质3层公共交通网络,对比度值与介数2种时变拓扑指标关联的抵抗效果,探究不同交通层抵抗系数对网络失效的影响程度;最后,在6组不同的网络结构上进行HCML模型与传统模型的对比,讨论建网方法、网络规模等不同网络性质的差异对模型有效性的影响,并结合实际客运数据验证HCML模型优越性。研究结果表明:3类表征方式中时变拓扑关联可以兼顾其余2类的优点;同等条件中网络在介数关联的抵抗特性作用下失效增速更缓,模型识别得到的对网络整体失效影响更大交通方式符合客流量实际;HCML模型在多种不同类型的多层交通网络中均可以有效实施,相比于传统模型,HCML模型的最终失效比例平均下降了5.78%,与实际交通级联失效过程更加拟合。
