在百年未有之大变局下,人类正在迎来以数字技术为代表的新一轮科技革命和产业变革,形成以数字基础、数字政府、数字社会、数字经济、数字能力为内容的数字生态。数字生态不断催生新技术、新产业和新动能,促进新质生产力发展,推动新质生产关系形成。当前,我国农业正面临着传统与现代并存二元结构转型升级关键期,必须充分发挥数字技术破解农业迂回生产分工难和产业组织集聚难的作用,以数字生态及与之相适配的制度组态推动农业新质生产力衍生与发展。基于此,以全国统一大市场建设为契机,运用生产力与生产关系的辩证关系原理,构建制度组态、数字生态与农业新质生产力培育的理论机制,综合运用必要条件分析法与动态定性比较分析法,利用我国30个省份(不包括西藏和港澳台地区)2019—2022年面板数据进行案例分析。定性比较分析法的单个必要性分析表明,数字生态要素的有效协同是培育高农业新质生产力的必要条件;必要条件分析表明,低数字能力与低数字经济制约农业新质生产力的培育;定性比较分析的条件组态充分性分析表明,培育农业新质生产力必须依靠数字生态要素及其匹配制度要素的有效组合,实施政府主导型、政府-市场双轮驱动型和政府-市场-社会三轮驱动型的组态路径。进一步加快农业新质生产力发展,应充分发挥全国统一大市场建设的数字化赋能作用,因地制宜选择农业新质生产力培育的组态路径,着力推动工业颠覆性技术在农业领域的广泛应用,大力加强农业数字化与数字化农业创新能力建设,全面深化以新质生产关系为导向的农业体制改革。

选取大包庄矿开采范围内所有地质剖面,建立二维有限元数值模型,计算一期、二期工程矿体开挖后不充填和全充填2种工况下的地表变形,通过地表变形值与标准值对比,圈定2种工况下的地表移动带,并对数值模拟法与工程类比法圈定的移动带进行了对比分析。结果表明:采空区不充填时数值模拟法与工程类比法圈定的范围较接近,开挖矿体较薄时,数值模拟法计算的地表移动范围在工程类比法确定的移动范围内;开挖矿体较厚时,数值模拟法计算的地表移动范围在工程类比法确定的移动范围外。采空区全充填时数值模法与工程类比法圈定的移动带范围差异较大,充填体限制了围岩变形,减小了地表移动范围。数值模拟法充分考虑了矿山复杂地质条件和开采技术条件,其圈定的移动带能更好地反映实际地表变形。

The Multiple Column Platform(MCP) semi-submersible is a newly proposed concept, which differs from the conventional semi-submersibles, featuring centre column and middle pontoon. It is paramount to ensure its structural reliability and safe operation at sea, and a rigorous investigation is conducted to examine the hydrodynamic and structural performance for the novel structure concept. In this paper, the numerical and experimental studies on the hydrodynamic performance of MCP are performed. Numerical simulations are conducted in both the frequency and time domains based on 3D potential theory. The numerical models are validated by experimental measurements obtained from extensive sets of model tests under both regular wave and irregular wave conditions. Moreover, a comparative study on MCP and two conventional semi-submersibles are carried out using numerical ***, the hydrodynamic characteristics, including hydrodynamic coefficients, natural periods and motion response amplitude operators(RAOs), mooring line tension are fully examined. The present study proves the feasibility of the novel MCP and demonstrates the potential possibility of optimization in the future study.

Molecular characterization of a defense-related AMP-binding protein gene, OsBIABP1, from rice

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2009年第10期10卷 731-739页

作者： Xin-chun ZHANG Xin yu Hui-juan ZHANG feng-ming song State Key Laboratory for Rice Biology Institute of Biotechnology Zhejiang University Hangzhou 310029 China

We cloned and characterized a rice gene OsBIABPI encoding an AMP-binding protein. The full-length cDNA of OsBIABP1 is 1912-bp long and is predicted to encode a 558-aa protein. OsBIABP1 contains a typical AMP-binding signature motif and shows high similarity to members of AMP-binding protein family. OsBIABP1 is expressed in stems, leaves and flowers of rice plants, but is not expressed, or expressed at a very low level, in rice roots. The expression of OsBIABP1 was induced by some defense-related signal molecules, e.g., salicylic acid （SA）, benzothiadiazole, jasmonic acid （JA）, and 1-amino cyclopropane- 1-carboxylic acid, which mediate SA- and JA/ethylene （ET）-dependent defense signaling pathways, respectively. Furthermore, the expression of OsBIABP1 is activated by the infection ofMagnaporthe oryzae, and the induced expression is quicker and stronger during early stages ofpathogenesis in incompatible interaction than that in compatible interaction between rice and M. oryzae. Our results suggest that OsBIABP1 may be a defense-related AMP-binding protein that is involved in the regulation of defense response through SA and/or JA/ET signaling pathways.

A hybrid-stress element based on Hamilton principle

引用

Acta Mechanica Sinica 2010年第4期26卷 625-634页

作者： song Cen Tao Zhang Chen-feng Li Xiang-Rong Fu yu-Qiu Long Department of Engineering Mechanics School of Aerospace Tsinghua University Beijing 100084 China Civil and Computational Engineering Centre School of Engineering Swansea University Swansea SA2 8PP UK College of Water Conservancy and Civil Engineering China Agriculture University Beijing 100083 China Department of Civil Engineering Tsinghua University Beijing 100084 China

A novel hybrid-stress finite element method is proposed for constructing simple 4-node quadrilateral plane elements, and the new element is denoted as HH4-3fl here. Firstly, the theoretical basis of the traditional hybrid-stress elements, i.e., the Hellinger-Reissner variational principle, is replaced by the Hamilton variational principle, in which the number of the stress variables is reduced from 3 to 2. Secondly, three stress parameters and corresponding trial functions are introduced into the system equations. Thirdly, the displacement fields of the conventional bilinear isoparametric element are employed in the new models. Finally, from the stationary condition, the stress parameters can be expressed in terms of the displacement parameters, and thus the new element stiffness matrices can be obtained. Since the required number of stress variables in the Hamilton variational principle is less than that in the Hellinger-Reissner variational principle, and no additional incompatible displacement modes are considered, the new hybrid-stress element is simpler than the traditional ones. Furthermore, in order to improve the accuracy of the stress solutions, two enhanced post-processing schemes are also proposed for element HH4-3β. Numerical examples show that the proposed model exhibits great improvements in both displacement and stress solutions, implying that the proposed technique is an effective way for developing simple finite element models with high performance.
