非平衡凝固和固态相变作为同热力学和动力学紧密相关的复杂理论体系,在物理冶金和凝聚态物理研究领域占据重要的地位。上述非平衡过程包含形核、生长和碰撞三个微观过程,其发生和发展均由一些竞争过程伴随、辅助甚至驱动。正确理解这些竞争过程决定了能否准确描述整个非平衡过程;材料制备中,其力学和物理/化学性能的提高也归根于这些竞争的发生与发展。因此,很有必要对非平衡凝固和固态相变中的竞争现象进行研究。本综述第一部分从形核/生长类相变角度对非平衡凝固和固态相变进行了概述,并强调了伴随其发生的竞争现象。第二部分立足于经典形核理论,对有关形核热力学、动力学以及形核方式的竞争现象进行了描述。第三部分对凝固中有关热扩散和溶质扩散以及固态相变中有关界面控制和扩散控制的生长方式竞争进行了描述。第四部分对本综述进行了总结性分析和概括,并对本领域的未来发展方向进行了预测。

为提高骨缺损修复的治疗效果,设计孔隙率为78.8%、70.8%、62.6%和54.4%的梯度多孔钛支架(分别表示为P1,P2,P3和P4),并通过选择性激光熔化技术进行制备。通过模拟和实验方法研究支架的成形性、显微组织、力学性能和渗透性能。模拟结果表明,4种梯度结构的最大等效应力和渗透性分别在569.1~1469.0MPa和(21.7~54.6)×10^(−9)m^(2)范围内,并且P3和P4具有更小的最大等效应力,表明P3和P4具有更高的强度。P3和P4结构支架的显微组织为α'马氏体,屈服强度和弹性模量分别为185.3~250.8MPa和6.1~9.7GPa。相比于P3结构支架,P4结构支架展现出更高的强度和与皮质骨更加匹配的弹性模量,并且其渗透性(18.6×10^(−9)m^(2))在人体骨组织渗透性范围内。因此,具有P4结构支架有望被应用于骨科植入领域。

Graphene nanosheet （GNS）/Al2O3 composite powder with homogeneously distributed GNSs has been fabricated from wet ball milled expanded graphite and Al2O3 , and then followed by the rotary evaporator at relatively low temperature to dry the mixture and the residual solvent was removed in atmosphere-vacuum pipe-type furnace accessing mixed gases of Argon and Hydrogen at 600℃ for 6h. During the process, homogeneously dispersed and mixed GNS/ Al2O3 composite powders with quite few damage of GNSs’ structure and properties have been obtained. The microstructures and grain sizes of GNS/Al2O3 composite powders have been investigated. The results showed that the addition of GNSs had diminished the size of Al2O3 particles and also the as-prepared GNSs/Al2O3 composite powders can be dispersed and mixed more homogeneously remarkably with the presence of GNSs.

In this work, an ultrasensitive electrochemical immunosensor for detecting the Pebrine disease related spore wall protein of Nosema bombycis(SWP N.b) was fabricated based on the amplification of hemin/G-quadruplex functionalized Pt@Pd nanowires(Pt@PdNWs). The synthesized Pt@Pd NWs possessed large surface area, which could effectively improve the immobilization amount of hemin/G-quadruplex DNAzyme concatamers produced via hybridization chain reaction(HCR). In the presence of SWP N.b, the hemin/G-quadruplex labeled Pt@PdNWs bioconjugations was captured on electrode surface and thus obtained electrochemical signal. After the addition of NADH into the electrolytic cell, hemin/G-quadruplex firstly acted as an NADH oxidase to locally produce HO in the presence of dissolved O. Then, the generated HO would be quickly reduced via hemin/G-quadruplex as a horseradish peroxidase mimicking(HRP-mimicking) DNAzyme, which finally promoted the self-redox reaction of hemin/G-quadruplex and a greatly enhanced electrochemical signal was obtained. Furthermore, Pt@Pd NWs with excellent electrocatalytic performance could also amplify electrochemical signal. With these amplification factors, the electrochemical immunosensor exhibited a wide linear range from 0.001 ng m L-1 to 100 ng m L-1 with a detection limit(LOD) of 0.24 pg m L-1, providing a new promise for the diagnosis of Pebrine disease.

集成测试是面向对象软件测试的重要组成部分。传统的类级集成测试顺序研究策略大多围绕如何降低测试成本开展工作，并未考虑赋予可靠性风险较大的节点较高测试优先级，从而影响软件测试效率。本文提出一种兼顾测试成本与测试效率的方法生成集成测试序列。根据软件在不同场景下的运行状态，将其映射成多层动态执行网络（multi-layer dynamicexecutionnetwork,MDEN）。借助该网络模型与概率风险评估方法为软件中每一个类赋予风险权重。利用成本收益分析方法，在生成测试用例的过程中保证两条原则：为高风险的类赋予较高权重，同时最小化测试桩复杂度。在此基础上，分析测试序列对软件系统总体运行风险的影响，从而提出评估测试序列优劣的度量方案。通过与现有算法的实验对比分析，证明所提算法生成的类级集成测试序列能有效降低测试代价。最后，将所提算法实现为自动生成集成测试序列的开源工具ITOsolution，。
