超细晶高熵陶瓷具有优异的机械及物理化学性能。然而,由于烧结后期晶粒的快速长大,使得超细晶高熵陶瓷的常规无压烧结制备非常困难。采用两步烧结法,克服了无压烧结致密化过程中晶粒的快速长大,成功制备了理论密度为99.0%、晶粒尺寸为162 nm的(Ce_(0.2)Nd_(0.2)Sm_(0.2)Gd_(0.2)Y_(0.2))_(2)Zr_(2)O_(7)高熵陶瓷。与常规无压烧结方法相比,两步烧结所制备的样品不仅具有更细小的晶粒尺寸,还具有更均匀的微观结构,这使其具有优良的力学性能,其硬度达到12.5 GPa,断裂韧性达到2.4 MPa·m^(1/2)。无压两步烧结法解决了传统无压烧结方法难以制备超细晶高熵陶瓷的困难,将有助于探索超细晶高熵陶瓷的物理化学性能,并有助于推动超细晶高熵陶瓷的广泛应用。

课堂互动是义务教育教学过程中最基础且至关重要的人际交流,它在课堂教学环境中表现为教师与学生、学生与学生之间的有益或消极影响,能够实现师生在心理或行为上的改变。根据柯林斯构建的互动仪式链在小学课堂互动的适切性,探讨小学课堂互动中共存身心缺失、共同焦点匮乏、共享情感消耗和象征性边界断裂等困境及其成因。通过聚焦核心功能提出复归身心意义、聚集共同焦点、积聚情感能量和消弭象征边界等解决策略,实现课堂中师生双主体的物理共在,内化师生主体的价值标准来聚焦关注点,激发师生主体积极的情感能量,打破师生之间的屏障。

从大气光信道中可以提取两个合法通信方用来加密其传输的机密信息的公共密钥。首先,为了打破湍流引起的光学波动的相关时间对每秒提取的不相关光信道测量样本的数量限制,提出了为合法通信双方配备随机调制的方法,并针对其实现测量样本去相关性进行了理论分析;其次,利用OptiSystem软件仿真分析了大气光信道水平路径传输距离为1 km,中湍流,调制方式为幅度调制条件下,合法通信方在无调制、单调制、双调制三种不同调制的情况下对光信道测量样本自相关性的影响。针对单调制的情形,分析了不同大气光信道传输系数相干时间、伪随机码生成速率、传输距离和信噪比对光信道测量样本自相关性的影响。结果表明,对比无调制情况,在相同采样间隔内,观测到的光信道测量样本的测量数据变化次数增多;同时施加随机调制的发射光信号,在小于湍流引起的光学波动的相关时间的采样间隔下,观测到的光信道测量样本,在滞后100个样本的延迟时间后的自相关性,从无调制情况下的0.676降低到单调制情况下的0.083和双调制情况下的0.035。

使用OM、SEM和EDS等手段,研究了第三代镍基单晶高温合金DD33不同V型缺口取向([100]、[210]和[110])片状试样从室温到不同上限温度(1000℃、1100℃和1200℃)的热疲劳过程中裂纹的萌生和扩展行为。结果表明,在三种上限温度,DD33合金的热疲劳性能均出现明显的各向异性。在三个上限温度[100]取向试样均表现出最好的热疲劳性能;上限温度为1000℃和1200℃[110]取向试样的热疲劳性能最差,上限温度为1100℃[210]取向试样的热疲劳性能最差。不同取向试样的热疲劳裂纹的萌生和扩展行为,均呈现出一定的晶体学取向规律。热应力、氧化以及滑移系的开动,导致不同取向试样裂纹的扩展速率不同。

温泉水量和水质是温泉开采利用的两个重要因素,安波温泉井群在干扰条件下单井出水量会受到影响,首先对井群分别做单井和干扰抽水试验,根据单井和干扰抽水时的水位降深计算在设计降深下的干扰出水量,最后对安波温泉水质做出综合评价。结果表明,井群之间存在明显的干扰,干扰出水量比单井出水量最高减少63.7%,另外温泉水中部分元素达到医疗热矿水浓度,但是还应做好防腐工作。实际开采时考虑井群之间的干扰和水质安全是安波温泉的可持续利用的重要保障。
