空间显式模型(Spatial Explicit Models)是一种用于研究地理空间和地理现象的数学模型。该模型将地理空间划分为离散的单元或单元格,并通过在这些单元之间定义关系和交互来描述地理现象的分布和变化。通过使用空间显式模型,我们可以更好地理解和解释地理现象的空间分布和相互作用,从而对地理空间进行更精确的建模和分析。{{short description|Motion characterized by chaotic changes in pressure and flow velocity}}

空间显式模型的结构包括两个主要部分:人口模拟器和景观地图。人口模拟器是一种计算机程序,用于模拟种群的动态,包括出生、死亡、迁移和繁殖等过程。景观地图描述了研究区域的空间分布,包括栖息地斑块、景观边界、走廊和其他景观特征。这些模型可以用于研究种群或群落如何受到景观结构变化的影响,包括景观组成(景观中不同栖息地类型或特征的相对或绝对数量)和景观形态(栖息地斑块和其他特征在景观中的精确位置)的变化。{{For2|the turbulence felt on an [[airplane]]|[[Clear-air turbulence]]|other uses|[[Turbulence (disambiguation)]]}}<references />

In [[fluid dynamics]], '''turbulence''' or '''turbulent flow''' is fluid motion characterized by [[Chaos theory|chaotic]] changes in [[pressure]] and [[flow velocity]]. It is in contrast to a [[laminar flow]], which occurs when a fluid flows in parallel layers, with no disruption between those layers.<ref name="Batchelor">{{cite book | last=Batchelor | first=G. | title=Introduction to Fluid Mechanics | year=2000}}</ref>
