西门子移动公司为欧洲市场研发了新一代的Vectron机车产品。该产品的开发吸取了"欧洲短跑手"(Eurosprinter)机车和"欧洲飞人"(Eurorunner)机车的运行经验,是第一次与订货无关而开发和制造的产品。新型机车采用了经过考验的技术措施和创新的设计方案。Vectron机车产品覆盖了各种不同的机车功率等级,既有多流制电力机车和双流制电力机车,也有单流制电力机车;既有货运机车,也有客运机车。该系列产品还补充了电传动内燃机车方案。Vectron系列的第1台内燃机车自2012年1月1日起已经达到了排放标准。机车采用一贯的模块化结构,由基础包和加装包组成,具有较高的经济性、可使用性、可靠性和较高的牵引性能。该系列机车既适用于德国境内运输,也适用于国际互换性运输。对于未来业务具有不确定性的欧洲铁路经营商而言,该机车产品是最佳的铁路牵引装备。

This paper presents characteristic features of the explosion of thin flat foils for currents and pulse risetimes ranging from 8 kA at 350 ns to1000 kA at ∼100 ns. Foils made of aluminum, copper, nickel, and titanium with thicknesses of 1–100 μm are tested. Various diagnostics inthe optical, UV, and x-ray spectral ranges are used to image the exploding foils from initial breakdown to complete destruction or *** is shown that foil explosion is a complex process that depends on many factors, but features common to all foils are found that do notdepend on the parameters of the generators or, accordingly, on the energy deposited in the foil: for example, the breakdown of flat foils underdifferent conditions occurs at the edges of the foil. For the first time, the formation of a precursor over the central part of the foil is shown,which significantly changes the dynamics of the foil explosion.
