核工业正在经历数字化、智能化变革,核电数据呈指数型增长,数据逐渐成为核电站的重要资产,然而缺少贯穿核电站全生命周期的数据管理体系。本文综述了我国核电站全生命周期数据管理的研究现状,剖析了核电站全生命周期数据管理面临的需求与挑战,构建了围绕核电站全生命周期各个节点和业务流的数据管理框架。研究认为,建立核电站全生命周期数据管理体系当务之急是推进核电行业全面数字化,规范统一核电站全生命周期数据标准;依据数据类型对全生命周期数据进行分类管理,合理设计数据模型;科学制定数据质量管控政策、数据质量度量标准,确保核电站全生命周期数据安全。为此建议,加快建立数据一体化平台,对核电站中物项、业务数据、三维仿真数据等进行目录化组织,促进跨业务系统间数据的互联互通;将区块链技术应用到核电站全生命周期数据管理,实现核电站全生命周期数据的真实可溯;加强核电与数字孪生技术、基于模型的系统工程方法的融合应用,提高核电站智能化发展水平;建立健全核电站数据绿色管理政策体系,实现数据中心的低碳、高效、可持续发展。

IN VITRO ACTIVITY OF EXTRACTS OF FIVE MEDICINAL PLANT SPECIES ON PLANT PATHOGENIC FUNGI
《农业科学与工程前沿(英文)》 2021年 第8卷 第4期 页码 635-644 doi: 10.15302/J-FASE -2020343
The antifungal effectiveness of extracts of five medicinal plant species was determined. The inhibitory activity of extracts of Eucalyptus tereticornis, Xanthium sibiricum, Artemisia argyi, Tupistra chinensis and Pyrola calliantha were evaluated against the mycelial growth of the plant pathogenic fungi Aspergillus niger, Botrytis cinerea, Penicillium digitatum, P. expansum, P. italicumand Rhizopus stolonifer. All plant extracts were prepared at 60°C using solvents (either water, 50% ethanol (v/v), 95% ethanol (v/v), ethyl acetate or petroleum ether). Fungicidal effects of all plants tested were confirmed. Different extracts from the same plant species gave different degrees of inhibition. All aqueous extracts had weak or no activity on all fungi tested. Ethyl acetate and 95% ethanol extracts from T. chinensis rhizomes gave greater inhibition and a broader spectrum inhibition than the other extracts. T. chinensis may have potential as a new natural fungicide and may be used for the preservation of agricultural and forestry products such as fruits and vegetables.

HEMIPTERAN-TRANSMITTED PLANT VIRUSES: RESEARCH PROGRESS AND CONTROL STRATEGIES
《农业科学与工程前沿(英文)》 2022年 第9卷 第1期 页码 98-109 doi: 10.15302/J-FASE-2021389
About 80% of plant viruses are transmitted by specific insect vectors, especially hemipterans with piercing-sucking mouthparts. Many virus-transmitting insects are also important crop pests that cause considerable losses in crop production. This review summarizes the latest research findings on the interactions between plant viruses and insect vectors and analyzes the key factors affecting insect transmission of plant viruses from the perspectives of insect immunity, insect feeding, and insect symbiotic microorganisms. Additionally, by referring to the latest applications for blocking the transmission of animal viruses, potential control strategies to prevent the transmission of insect-vectored plant viruses using RNAi technology, gene editing technology, and CRISPR/Cas9+ gene-driven technology are discussed.

Causations of failure in megaprojects: A case study of the Ajaokuta Steel Plant project
Oluwole Alfred OLATUNJI
《工程管理前沿(英文)》 2018年 第5卷 第3期 页码 334-346 doi: 10.15302/J-FEM-2018011
This paper uses project organizational theories to draw lessons from a historic megaproject, the Ajaokuta Steel Plant (ASP). Archival reports on the ASP were explored to identify the unique attributes of the project; the political wrangling that underplayed its evolution, its economic significance and organizational impacts. Findings suggest the goals of the ASP project were, and still are, unambiguous. Failure occurred as socio-political forces aggravated the project’s complex milestones. Stakeholders were impatient with pre-project investigations. During planning, owners ignored opinions that were contrary to their expectations. While delays lingered, pressures from the global economy weakened the project’s motivation to succeed. These combined to turn the project’s outcomes into a chaotic situation that triggered dire implications. Despite about 1400% overrun in cost, the success achieved on the plant was 28% at commissioning. Contractors remained on site until eight years after commissioning. Six key elements of the 482 items in the ASP project contract were not delivered nearly 40 years on. A simplistic look at these suggests poor planning is the main problem. However, planning issues is not entirely strange in greenfield projects. The paper draws strength from project organization theories to explain what was poor about the planning. Socrates’ generic management theory was used to explain the role of leadership in the failure of the ASP project. McGregor’s Theory X and Theory Y explain the significance of stakeholders’ integration in megaprojects. Systems and chaos theories were used to explain the sensitivity of the ASP project to uncertainties. Narratives on these combine well to inspire stakeholders of megaprojects on where and how to seek courage in making effective plans that can help achieve success in complex projects. While normative literature only recognizes project success in a definitive perspective, this study provides insights from failure as an instrument to trigger sublime reflections.
