关于推广现场混装炸药车技术的一些思考

我国是工业炸药的生产和使用大国,连续多年的产量都超过了400万t,同时工业炸药作为典型的危险物品,与公共安全息息相关,是社会治安管理的重点监管对象。工业炸药现场混装车技术彻底改变了传统商品炸药的生产、供营和使用模式,本质安全性高是其最突出的特点。大力推广应用现场混装车技术无论是对于提高工业炸药的安全生产管理水平,还是对于提升社会治安管理水平,都具有重要意义,因此受到国家法规政策的鼓励。分析了工业炸药现场混装技术的优势,尤其是对于公共安全的有利作用,研究了现行管理模式存在的弊端,提出为促进工业炸药现场混装技术在我国顺利推广,贯彻创新驱动发展战略,通过体制机制创新,建立由公安机关对工业炸药现场混装技术进行统一管理的更有利的监管模式。鼓励有条件的爆破公司购买和使用现场混装车,大幅度减少工业炸药固定生产点、库房和成品炸药运输等危险源。     

Research on Combined Construction Technology for Cross-Subway Tunnels in Underground Spaces

Given the increasingly notable segmentation of underground space by existing subway tunnels, it is difficult to effectively and adequately develop and utilize underground space in busy parts of a city. This study presents a combined construction technology that has been developed for use in underground spaces; it includes a deformation buffer layer, a special grouting technique, jump excavation by compartment, back-pressure portal frame technology, a reinforcement technique, and the technology of a steel portioning drum or plate. These technologies have been successfully used in practical engineering. The combined construction technology presented in this paper provides a new method of solving key technical problems in underground spaces in effectively used cross-subway tunnels.

Relational Logging Design Pattern

Observability and traceability of developed software are crucial to its success in software engineering. Observability is the ability to comprehend a system’s internal state from the outside. Monitoring is used to determine what causes system problems and why. Logs are among the most critical technology to guarantee observability and traceability. Logs are frequently used to investigate software events. In current log technologies, software events are processed independently of each other. Consequently, current logging technologies do not reveal relationships. However, system events do not occur independently of one another. With this perspective, our research has produced a new log design pattern that displays the relationships between events. In the design we have developed, the hash mechanism of blockchain technology enables the display of the logs’ relationships. The created design pattern was compared to blockchain technology, demonstrating its performance through scenarios. It has been determined that the recommended log design pattern outperforms blockchain technology in terms of time and space for software engineering observability and traceability. In this context, it is anticipated that the log design pattern we provide will strengthen the methods used to monitor software projects and ensure the traceability of relationships.
