Grain boundaries,including low-angle,high-angle,and coinci-dence boundaries,are intrinsic interfaces in polycrystalline *** heat-treatment at sufficiently high temperatures,grain boundary migration occurs because the grain boundaries are ther-modynamically ***,grain growth occurs due to a decrease in grain boundary area after heat-treatment[1].In general,there are two types of grain growth:normal grain growth,where grains grow uniformly,and abnormal grain growth,where one or a few grains selectively grow and engulf surround-ing smaller grains,leading to the formation of large grains,some-times several millimeters or greater in size[2..The classical tech-nique to achieve abnormal grain growth is the strain-annealing method,which involves subjecting the material to a small strain followed by annealing[3,4].This method has been reported to ob-tain single-crystal wires or plates[1].Additionally,abnormal grain growth can be achieved by plastic straining at high temperatures,resulting in the fabrication of large grains or single crystals[5].However,the above methods are not applicable to components with complicated shapes due to the inevitable deformation ***,Omori et *** a simply method of abnor-mal grain growth to fabricate ultra-large grains,even single crys-tals,in Cu-Al-Mn[1],Fe-Mn-Al-Ni[2.,and Fe-Mn-Al-Ni-Cr[6]*** method involves applying cyclic heat treatment between a high temperature BCC single-phase region and a low tempera-ture BCC+FCC two-phase region[1,2.6-12..Note that the cyclic heat treatment resulted in the formation of BCC sub-grain struc-tures responsible for abnormal grain growth[1,2.6-12..In addition,Yang et *** that abnormal grain growth occurred at above 900℃,and large-grains,even single crystals,were obtained only through annealing cast Cu-based polycrystalline alloys contained coherent nano-particles[13,14].Notably,the cyclic heat treatment and annealing cast alloys are deform

道德判断的本质和发展问题是道德研究的基本问题。以柯尔伯格为代表的理性主义主张推理是道德判断的核心,而以海特为代表的社会直觉主义则提出“直觉在先、推理在后”的道德判断理论。研究发现,这两种理论在道德判断的来源、基础、过程等方面均有争论:理性主义关注道德判断中的理性和推理,而社会直觉主义关注道德判断中的情感和直觉;理性主义将公正与关怀两种道德原则作为道德的基础,社会直觉主义确定了6种道德直觉为道德的基础;理性主义主张道德判断的过程是理性驾驭情感,社会直觉主义则认为道德判断是由情感自动驱动的过程。道德判断理论的争论不仅促进了理论本身的传播与发展,也形成了一批本土化的研究成果,促进了中国道德教育研究范式的转型、研究视野的拓宽,并推动了中国道德教育的实践变革。

为解决10 km甚至2. km以上的高寒高海拔超长公路隧道消防供水系统设计中洞外设置供水系统被冻结、洞内管网严重超压等难题,通过对乌尉高速天山胜利隧道消防设计的难点,以及常规的隧道外常高压供水系统及稳高压供水系统在该隧道中难以实施等问题展开深入研究,提出天山胜利隧道内设置高位消防水池及将隧道内消防管网进行分区供水的设计方案并详细论述。对于10 km甚至2. km以上的高寒高海拔超长公路隧道消防供水系统的设计:1)隧道消防给水宜采用高位消防水池供水的常高压供水系统;2.常规的隧道外常高压供水系统及稳高压供水系统在高寒高海拔超长公路隧道中无法实施,可考虑隧道内置高位消防水池的设计;3)隧道内置高位消防水池的数量、设置间距、设置高度等应根据隧道的长度、纵坡等综合考虑并进行水力计算后确定;4)隧道内置高位消防水池的常高压供水系统能解决这类隧道消防供水系统设计中管网严重超压的难题,具有供水安全可靠、施工难度较小、经济、环保等优点。
