Researchers have recently achieved significant advances in deep learning techniques, which in turn has substantially advanced other research disciplines, such as natural language processing, image processing, speech recognition, and software engineering. Various deep learning techniques have been successfully employed to facilitate software engineering tasks, including code generation, software refactoring, and fault localization. Many studies have also been presented in top conferences and journals, demonstrating the applications of deep learning techniques in resolving various software engineering tasks. However,although several surveys have provided overall pictures of the application of deep learning techniques in software engineering,they focus more on learning techniques, that is, what kind of deep learning techniques are employed and how deep models are trained or fine-tuned for software engineering tasks. We still lack surveys explaining the advances of subareas in software engineering driven by deep learning techniques, as well as challenges and opportunities in each subarea. To this end, in this study, we present the first task-oriented survey on deep learning-based software engineering. It covers twelve major software engineering subareas significantly impacted by deep learning techniques. Such subareas spread out through the whole lifecycle of software development and maintenance, including requirements engineering, software development, testing, maintenance, and developer collaboration. As we believe that deep learning may provide an opportunity to revolutionize the whole discipline of software engineering, providing one survey covering as many subareas as possible in software engineering can help future research push forward the frontier of deep learning-based software engineering more systematically. For each of the selected subareas,we highlight the major advances achieved by applying deep learning techniques with pointers to the available datasets i

采用中频磁控溅射技术在钼圆片表面镀覆钌薄膜,通过X射线衍射仪、扫描电镜、平整度仪、宏观浸蚀试验和百格测试等对镀层进行表征和检测,研究不同沉积温度对薄膜微观结构和附着力的影响。结果表明,随着沉积温度由室温升至200℃,钌薄膜的表面平整性和致密性逐步改善,附着力得以提高;200℃沉积薄膜的膜/基结合力最大,其微观结构、致密性等也均达到最优;但当沉积温度进一步提高到300℃时,钌薄膜的表面起伏反而增大,附着力有所下降。

作者： Wen-tong Liu Yi-dong Wu Lei Gao Jing-yang Chen Cheng-bo Xiao Xi-dong Hui State Key Laboratory for Advanced Metals and Materials University of Science and Technology Beijing Science and Technology on Advanced High Temperature Structural Materials Laboratory Beijing Institute of Aeronautical Materials

The size and shape effect(SSE) of components has become a critical issue for mechanical properties, application reliability, and processing. In this study, the creep rupture life(CRL) of components with different wall thicknesses and positions in a combustion chamber casing simulator made of K439B superalloy was investigated. The intrinsic mechanisms of the SSE were explored from the dendrite structure, volume fraction and size of the γ' phase, and element segregation, etc. It is shown that this casting exhibits a strong SSE of creep rupture life, characterized by a significant difference in the CRL values up to 60% with the variation of wall thickness and position in the casing. In terms of casting technology, the influence of SSE on CRL is actually determined by the cooling rate. The SSE on the creep rupture life originates from the dendrite structure(such as the secondary dendrite arm spacing), volume fraction size of the γ' phase in the dendrite trunk, and elements segregation rate. This work may have implications for the design and application of engineering components with large sizes and complex structures.

目的评价高分辨肛门直肠测压在接受生物反馈治疗(BF)的出口梗阻型便秘(OOC)患者临床应用价值。方法选择诊断为OOC且接受BF治疗的77例患者,均在BF治疗前后予以高分辨肛门直肠测压,记录并比较参数。分别应用临床症状评分及高分辨肛门直肠测压评估BF治疗疗效,并比较两种方法的差异。应用Logistic回归分析评估肛门直肠测压参数与生物反馈治疗有效率的相关性。结果 OOC患者BF治疗后直肠感觉阈值、直肠最大耐受量均较治疗前减少(P0.05)。临床症状评分评估患者治疗后有效率为76.62%,高分辨肛门直肠测压评估有效率为77.92%,两者差异无显著性(P=0.078)。以临床症状评分标准为金标准,高分辨率肛门直肠测压的敏感度为94.92%,特异度为77.78%,准确度为90.91%。多元Logistic回归分析显示,肛管最大收缩压、直肠感觉阈值是生物反馈治疗有效率的独立预测因子(P<0.05)。结论高分辨肛门直肠测压能有效反映OOC患者的肛门直肠动力学异常,评估接受BF治疗后的临床疗效。
