随着数字经济的快速发展,以及以人工智能为代表的新一代信息技术在会计领域的深度应用,智能会计作为一种新型会计模式应运而生。智能会计是“会计与智能”深度融合的产物,其基本特征是人工智能技术在会计系统中的匹配应用。智能会计不仅延承了传统会计的角色,保留了会计作为反映和管理工具的本质特征,也拓展了会计的角色。智能会计在企业中可以承担智能反映者、智能管理者、智能价值创造者的角色。从会计环境的内环境和外环境两个维度,提出促进智能会计角色得以实现的潜在策略:在会计内环境维度,应注重会计组织的智能化建设、提升会计人员的角色认知与角色实践能力;在会计外环境维度,应注重智能会计规则体系建设、智能会计软件的开发。

Cluster analysis is a well-known technique that is used to analyze various types of data. In this study, cluster analysis is applied to geochemical data that describe 1444 stream sediment samples collected in northwestern Xinjiang with a sample spacing of approximately 2 km. Three algorithms （the hierarchical, k-means, and fuzzy cmeans algorithms） and six data transformation methods （the z-score standardization, ZST; the logarithmic transformation, LT; the additive log-ratio transformation, ALT; the centered log-ratio transformation, CLT; the isometric log-ratio transformation, ILT; and no transformation, NT） are compared in terms of their effects on the cluster analysis of the geochemical compositional data. The study shows that, on the one hand, the ZST does not affect the results of columnor variable-based （R-type） cluster analysis, whereas the other methods, including the LT, the ALT, and the CLT, have substantial effects on the results. On the other hand, the results of the row- or observation-based （Q-type） cluster analysis obtained from the geochemical data after applying NT and the ZST are relatively poor. However, we derive some improved results from the geochemical data after applying the CLT, the ILT, the LT, and the ALT. Moreover, the k-means and fuzzy cmeans clustering algorithms are more reliable than the hierarchical algorithm when they are used to cluster the geochemical data. We apply cluster analysis to the geochemical data to explore for Au deposits within the study area, and we obtain a good correlation between the results retrieved by combining the CLT or the ILT with the k-means or fuzzy c-means algorithms and the potential zones of Au mineralization. Therefore, we suggest that the combination of the CLT or the ILT with the k-means or fuzzy c-means algorithms is an effective tool to identify potential zones of mineralization from geochemical data.

对ASR发生的化学机理进行了回顾。ASR发生的化学反应机理可以分为2步:1骨料颗粒外部OH-离子入侵活性颗粒,断开活性颗粒≡Si-O-Si≡的链接,形成分散的Si2+;2外界离子(K+,Na+,OH-)和≡Si-O-结合形成水化石灰石-Na-Si-复合物,该复合物吸水膨胀产生压力。利用ASR的化学反应机理分析和评价了普通混凝土中单种抑制材料抑制ASR的效果。由于HPC配合比设计时组成材料众多,根据ASR化学反应机理,研究HPC结构中用来抑制ASR的措施,必须考虑各种材料的相互影响和叠加效应。结论认为要保证HPC结构中抑制ASR的效果,关键是降低HPC结构中活性颗粒周围孔溶液中离子的浓度,防止合适浓度的OH-出现。

碳/碳(C/C)复合材料广泛应用于高超声速飞行器,其表面有碳化硅(Si C)基的保护涂层,旨在将氧气与底层基体C/C隔离。涂层中存在的孔隙成为氧气直达底层C/C材料的通道。C/C材料被氧化,侵蚀出空穴,严重时造成局部热防护失效。针对原有的气体扩散两步模型进行了改进,去掉了O2/CO反应界面固定的限制,考虑了空穴中扩散的影响,提出了折合孔隙深度与弯曲因子的处理方法。采用改进模型模拟涂层下面C/C材料氧化空穴半径,计算值与试验测量值吻合良好,验证了模型的有效性。改进模型可用于预测涂层保护的基体C/C材料的氧化空穴尺寸和评估氧化损伤。
