工业互联网平台是推进“数实融合”的新型基础设施,需要掌握数字技术的平台企业与掌握业务诀窍的行业用户共创共建,这一过程面临着平台企业“共性”能力开发与用户“个性”方案需求的突出矛盾。本文采用纵向案例方法,以“树根互联”为例开展理论建构,研究发现:构建工业互联网平台可以采取“耦合需求开发产品、解耦沉淀能力模块、构建松散耦合生态”的过程,通过“项目—产品—模块—生态”的演进,应对“个性与共性”的矛盾。首先,通过耦合用户个性需求定制项目解决方案,构建数字模型将方案转化为产品;其次,将产品所需能力与特定用户的需求解耦,沉淀为可被重组调用的共性能力模块;最后,鼓励生态领先用户构建子平台,满足大量细分行业的个性需求,平台企业则转向建设底层更共性的使能模块,平台企业与生态子平台形成相嵌合作的“松散耦合”生态。本文针对工业互联网平台构建面临的“个性与共性”矛盾问题,归纳出“耦合—解耦—松散耦合”的应对机制,贡献于平台构建和组织间松散耦合模块架构生成动力的研究。本文结论适配中国制造业梯度分布的特征,对工业互联网平台的考核评价、推广应用和提升国际竞争力具有启示意义。

We develop a fractional-degree expectation dependence which is the generalization of the first-degree and second-degree expectation *** motivation for introducing such a dependence notion is to conform with the preferences of decision makers who are mostly risk averse but would be risk seeking at some wealth *** investigate some tractable equivalent properties for this new dependence notion,and explore its properties,including the invariance under increasing and concave transformations,and the invariance under *** also extend our results to a combined fractional-degree expectation dependence notion includingε-almost firstdegree expectation *** applications on portfolio diversification problem and optimal investment in the presence of a background risk illustrate the usefulness of the approaches proposed in the present paper.

Quantized vortices are important topological excitations in Bose–Einstein condensates. The Gross–Pitaevskii equation is a widely accepted theoretical tool. High accuracy quantized-vortex solutions are desirable in many numerical and analytical studies. We successfully derive the Padéapproximate solutions for quantized vortices with winding numbers ω = 1, 2, 3, 4, 5, 6 in the context of the Gross–Pitaevskii equation for a uniform condensate. Compared with the numerical solutions, we find that(1) they approximate the entire solutions quite well from the core to infinity;(2) higher-order Padé approximate solutions have higher accuracy;(3) Padé approximate solutions for larger winding numbers have lower accuracy. The healing lengths of the quantized vortices are calculated and found to increase almost linearly with the winding number. Based on experiments performed with 87Rb cold atoms, the healing lengths of quantized vortices and the number of particles within the healing lengths are calculated, and they may be checked by experiment. Our results show that the Gross–Pitaevskii equation is capable of describing the structure of quantized vortices and physics at length scales smaller than the healing length.

随着分布式电源(distributed generation,DG)在配电网中的大规模接入,合理选择接入方式以及评估现有电网对高渗透率分布式电源的适应性,已成为保障电网安全运行的关键环节。提出了一种创新的配电网新能源承载力的多目标决策评估方法,旨在构建一套完善的DG承载力模型。该模型充分考虑了DG出力及负荷功率的不确定性,运用经典鲁棒优化算法,能够精确计算出适用于任意接入位置的DG最大接入容量。在此基础上,进一步对最大容量的接入方式进行了最恶劣情况检验,以确保评估结果的可靠性和准确性;为了全面评估配电网DG承载力,还选取了合适的评估指标,构建了一套综合评估指标体系。通过基于图论的多目标决策加权方法,计算了各评估指标的权重,进而得到了配电网DG承载力的综合评估结果,克服了传统方法的局限性。在IEEE 33节点算例上验证了所提模型和方法的有效性。

This paper deals with a linearization method of the nonlinear resistance function and the effect of using the simplified limit state equation instead of the practical limit state equation on reliability analysis. The structural reliability analysis for two reinforced concrete members with the practical limit state equation is compared with that with simplified limit state equation. The result of the comparison is presented in this paper.

This study looks into the influence of cosmic radiation at high altitudes on human bodies. Results reveal that the cytokinesis-block micronuclei (CBMN) and conventional cultured micronuclei in peripheral blood lymphocytes, serum levels of lipid peroxide, superoxide dismutase, and the total antioxidation capacity by chemical colorimetry all increased significantly in aircrew members. There exists a linear relationship between the CBMN and the average annual effective doses of radiation received or the average annual flying hours. With both of them, a trend shows that the serum lipid peroxide levels increase as well. Either the lipid peroxide or CBMN can sensitively reflect the recent changes in flight load. These findings indicate that cosmic radiation impairs the stability of chromosomes and genome, and induces lipid oxidative damage in aircrews; Lymphocyte CBMN and serum lipid peroxide can be used as monitoring indicators in the cosmic radiation protection for aircrew members.

关键词： cosmic radiation aircrew micronucleus lipid peroxide antioxidation capacity.

我国人民生活现代化具有鲜明的中国特色,是以共同富裕为目标,以实现物质财富足够充裕为主体,以人民精神上富有、社会公平与正义、人与自然和谐共生为三翼的现代化实现过程。在此过程中,因资源禀赋的差异西部地区发展相对滞后,故研究西部地区人民生活现代化的实现是推动我国现代化实现的重要一环。本文在对人民生活现代化概念界定的基础上,构建了西部地区人民生活现代化的指标体系和评判标准,通过对2019年西部地区人民生活现代化实现程度进行评估,以及运用灰色预测模型对未来15年西部地区发展趋势的研究,预测至2035年西部地区能够实现人民生活现代化,但具体指标实现程度差异较大。同时,提出不断提升人民收入水平、推动公共服务转型与发展、促进公共文化服务发展、坚持绿色发展观多维度实现路径。
