谈固体地球动力学系统的自组织

Learning the spirit of scientist from dialectic principles

地球在3.8 Ga前不断有小星体撞击,属于不稳定的开放系统,积累了大量物质和能量。太古宙以后开始形成了准圈层结构,转变为封闭的能量消散系统,并开始建立了系统整体凝聚力和活力之间高度平衡的自组织机制。固体地球系统的重力和化学亲和力产生地球系统物质向内运动的凝聚力。地球存储在地核中的热能和放射性物质的核能,是驱动和维持着固体地球内部物质向外运动的活力来源。地球的自组织指的就是自我调控系统凝聚力和活力之间平衡的调节能力。固体地球系统局部时空尺度的物质运动是各态遍历的,大尺度全局的物质运动规律是确定性的,是自组织机制发挥作用的结果。固体地球系统的自组织能力现在还保持在很高的水平。

The Earth,which was hit by small stars 3.8 billion years ago,is an unstable open system that accumulates a great deal of material and energy.Afterwards,it formed spherical structures,becoming a closed energy dissipation system,and began to establish a high-degree self-organization system and the balance mechanism between cohesion and vigour forces.The gravity and chemical affinity forces of the solid earth system produce the cohesion force for inward motion of the earth masses.The thermal energy and radioactive nuclear energy stored within the Earth drive the outward movement of solid Earth’s internal masses.The earth’s self-organization refers to the ability to balance the cohesion and vigour forces in the self-regulating way.The material motion of the local space—time scales of the solid earth system is ergodic,and the large-scale global material motion law is deterministic and the result of the function of the self-organizing mechanism.The self-organizing capacity of the solid Earth system today is still at a very high level.
