Take air pressure,for example.The familiar isobars on weather chartsdefine regions of equal pressure,similar to the elevation contours ona map.Indeed,an isobar can be thought of as a kind of "coastline",described by its own fractal law.But there’s a key difference:acoastline’s shape is defined only at one specific value of height – sealevel.In contrast,the isobars of air pressure form a whole array ofshapes at different heights,like Russian dolls nested within eachother.Air pressure is what mathematicians call a multifractal field,described by a whole set of power laws,rather than just one.

楼主,这个真是纯手工翻译啊!
拿气压来举个例子,气候制图上常见的等压线定义了等压层,与海拔等高线图相似.的确,等压线可以被认为是一种“海岸线”,用其自身的不规则碎片形规律所描述.但是,有一个重要的不同点是：海岸线的形状仅仅以一个特殊海拔高度值所定义——也就是海平面.相比下,大气等压线在不同高度形成了一整批形状,像俄罗斯套娃一样嵌套在彼此中.气压就是数学家所谓的一个多边不规则碎片形区域,用一整套动力定律所描述,而不仅仅是一个.
