Software security poses substantial risks to our society because software has become part of our life. Numerous techniques have been proposed to resolve or mitigate the impact of software security issues. Among them, software testing and analysis are two of the critical methods, which significantly benefit from the advancements in deep learning technologies. Due to the successful use of deep learning in software security, recently,researchers have explored the potential of using large language models(LLMs) in this area. In this paper, we systematically review the results focusing on LLMs in software security. We analyze the topics of fuzzing, unit test, program repair, bug reproduction, data-driven bug detection, and bug triage. We deconstruct these techniques into several stages and analyze how LLMs can be used in the stages. We also discuss the future directions of using LLMs in software security, including the future directions for the existing use of LLMs and extensions from conventional deep learning research.

通过拉伸试验,利用扫描电镜与光学显微镜等手段,比较了搅拌摩擦焊(FSW)和变极性钨极氩弧焊(VPTIG)两种焊接方法对2219铝合金板材力学性能的影响。结果表明,无论何种焊接方法均使2219铝合金板材的强度和塑性下降,但是FSW焊接接头强度以及塑性等力学性能明显优于VPTIG焊熔焊接头。拉伸试样断口形貌以及显微组织分析显示,FSW焊核区组织均匀细密,断裂位置位于后退侧热影响区与焊核区的交界处。VPTIG焊接接头易出现气孔缺陷,熔合区是最薄弱环节。

碳纤维复合材料因其强度高、质量轻、导热性能出众,在外空间和核工业等领域中的关键部件中得以应用。碳纤维复合材料与金属主要是通过螺栓、胶结、钎焊或扩散焊连接在一起。其中,在钎焊过程中,多数钎料在这类复合材料表面并不润湿,通常采用活性钎料,在高温和高真空的条件下进行;钎料的种类不同,钎焊接头的强度差异也很大。本文对碳纤维复合材料与金属铜、钛、铌、铝等金属的连接方法和相关研究进展作了总结,对其接头的力学性能测试方法作了介绍,并对该领域的研究方向发展做了展望。
