Parallel tempering simulation is widely used in enhanced sampling of systems with complex energy *** hereby introduce generalized canonical ensemble(GCE)instead of the usual canonical ensemble into the parallel tempering to further improve abilities of the simulation *** utilizes an adapted weight function to obtain a unimodal energy distribution even in phase-coexisting region and then the parallel tempering on GCE yields the steady swap acceptance rates(SARs)instead of the fluctuated SARs in that on canonical *** the steady SARs,we can facilitate assign the parameters of the parallel tempering simulation to more efficiently reach equilibrium among different *** illustrate the parallel tempering simulation on GCE in the phase-coexisting region of 2-dimensional Potts model,a benchmark system for new simulation method *** result indicates that the new parallel tempering method is more efficient to estimate statistical quantities(i.e.,to sample the conformational space)than the normal parallel tempering,specially in phase-coexisting regions of larger systems.

Laser powder deposition was applied to fabricate the Ti-6.5Al-3.5Mo-1.5Zr-0.3Si （wt%）/Ti-47Al- 2Cr-2Nb-0.2W-0.15B （at%） bi-material system. The asdeposited TC11 alloy shows a basket-wave-like morphology while the as-deposited y-TiAl alloy consists of fully α2/γ lamellar microstructures. Regarding the thermal mismatch between TC11 and γ-TiAl during processing, the interface microstmcture evolution was concerned. The transformation pathway was illustrated. It is found that the content changes of Al elements and β-stabilizers Mo, Cr, and Nb are responsible for the evolution of microstructures at the interface. The fracture surfaces are located at the y-TiAl side. The bi-material shows a brittle-fracture manner, with the ultimate tensile strength of 560 MPa.

1906年至1911年间,晚清小说家对五大臣几乎清一色地作西游化、妖魔化等艺术处理,这是公使形象书写史上的别样呈现。晚清小说对五大臣形象的刻画,妙趣横生且极具寓言化特色,整体追求内在的“荒诞”与“怪、奇、丑”等审美观念,这与立宪幻梦破灭后形成的巨大落差不无关系。小说家普遍对之进行充满丑恶的描写并非偶然,正反映了彼时国民迫切打破封建专制束缚的心声。深究五大臣被晚清小说家塑造为“跳梁丑角”,乃至不断被妖魔化的成因,不仅在于日益高涨的革命风潮及其不可逆转的历史趋向,也在于报刊媒介对其的持续关注与负面报道。五大臣的文学形象丰富了中国近代文学小说人物的多元构成,也是百余年来我们探寻民族复兴之路的一个缩影,彰显了中国人走向现代化的曲折历程。
