从知识社会学意义来看,思维创新活动的社会化过程存在着三个阶段。在潜思维创新阶段存在着社会思维系统内部由新质差别所引起的对常规思维平衡态的偏离即微观涨落。在趋显思维创新阶段,这种思维创新的微观涨落由于处在远离常规思维平衡态的非线性区域而不断得以放大与扩展,形成创新思维"巨涨落",从而推动着创新思维自身系统向新的有序化创新思维系统结构演进。在显思维创新阶段,各种思维创新主体及其思维知识信息相互融合和协同,在新的层次上形成了以新的思维范式为核心的社会创新思维有序化结构即社会创新思维耗散性结构。 相似文献

该文是关于区域经济协调发展研究方面一系列论文的引论。把自组织理论应用于区域经济研究,在描述中国区域经济格局和简要评述国内外研究情况的基础上,指出区域经济研究应特别强调协调性。从内容、运行机制和具体操作三方面对区域经济的协调性作了探讨。提出了二个区域经济协调原则:①在不公平程度不超出一定限度的条件下,力求有最高的效率。给出了评价区域经济不公平程度的指标——区域经济差距的概念和计弹方法。对中国区域经济差距作了初步实证分析。给出中国区域经济差距的界限为5.5～6.5倍;②以市场机制的自组织作用为基础,以政府干予的组织机制为条件,政府干予的组织作用应能创造这样一种条件:既能使市场机制的自组织作用的积极方面得到充分发挥;又能使市场机制的自组织作用的消极方面得到有效抑制。 相似文献

首先从农产品供应链的目标参量、状态参量、控制参量和随机扰动因素深入分析农产品供应链自组织运作机理,认为农产品供应链目标的实现与成员企业的良好运作状态参量密不可分,而控制参量和随机扰动因素决定了成员企业的运作状态水平。以运作机理为基础构建农产品供应链协同演化模型,分析农产品供应链协同演化自组织过程和动力因素,以及农产品供应链在竞争阶段和协同阶段随机涨落力对供应链演化所起的作用,从而为农产品供应链协同管理提供理论依据。 相似文献

Ecosystem stays far from thermodynamic equilibrium. Through the interactions among biotic and abiotic components,and encompassing physical environments,ecosystem forms a dissipative structure that allows it to dissipate energy continuously and thereby remains functional over time. Biotic regulation of energy and material fluxes in and out of the ecosystem allows it to maintain a homeostatic state which corresponds to a self-organized state emerged in a non-equilibrium thermodynamic system. While the associated self-organizational processes approach to homeostatic state,entropy(a measure of irreversibility) degrades and dissipation of energy increases. We propose here that at a homeostatic state of ecosystem,biodiversity which includes both phenotypic and functional diversity,attains optimal values. As long as biodiversity remains within its optimal range,the corresponding homeostatic state is maintained. However,while embedded environmental conditions fluctuate along the gradient of accelerating changes,phenotypic diversity and functional diversity contribute inversely to the associated self-organizing processes. Furthermore,an increase or decrease in biodiversity outside of its optimal range makes the ecosystem vulnerable to transition into a different state. 相似文献

Complex science is a new science flourishing in 70s of the 20th century. It is a huge integration of Natural and Social Sciences and is also a huge storm in the Thinking Science. Compared with Philosophy, Technique and Art, the Architecture lags behind them. But it is not the reason that the architects need not care about and absorb the mind of other reign. The architects can recognize the world in a systematic and comprehensive way from exercising their mind by learning complex science. The self-organization-critical theory and fractal-geometry in complex science is close and related to topography, city planning, space and shape of building. The revolution of design will be raised by artificial-intelligence; therefore, there will be a better future for our residential environment by our effort. 相似文献

Coal mining waste dumps are representative artificial accumulations of bulky rock and soil material. Certain factors make these dumps possess characteristics such as self organized criticality, nonlinear shear strength of the waste accumulation. We discusse the main waste dump characteristics and subsequently produced numerical simulations of the stability of waste dumps of various heights using the Fast Lagrangian Analysis of Continua and based on the Hoek Brown nonlinear strength criterion. The simulation calculation results show that the stability is a dynamic evolving process corresponding to increasing waste dump height. Safety factors, based on a nonlinear rule, vary with the waste dump height. Theoretical analysis and calculated outcomes reveal a progressive failure rule of waste dumps, and all indicate the methods we put forward are reasonable. 相似文献

坡面土壤细沟侵蚀自组织分析 总被引：4，自引：0，他引：4
坡面土壤细沟侵蚀过程是坡面土壤颗粒的一种宏观定向有序运动，这种现象在耗散结构中称为自组织现象。细沟侵蚀愈剧烈，对土地生产力的破坏愈严重。本文利用耗散结构理论对坡面土壤细沟侵蚀进行了分析，对细沟侵蚀的防治进行了探索，提出了一些新的治理思路。 相似文献
