Distribution and Fractal Characteristics of Outdoor Particles in High-Rise Buildings Based on Fractal Theory
نویسندگان
چکیده
It is of great significance to understand the particle distribution characteristics at different heights effectively control pollution. Based on fractal theory, dimension outdoor particles in a high-rise building Xi’an and its relationship with concentration sizes are discussed analyzed this paper. The results indicate that atmosphere mainly composed fine average proportion ranging from 0 1.0 µm approximately 99.885% total particulates. ranges 5.014 5.764, an 5.456. In summer, 17th floor was largest, 5.764. summer relatively high, being 0.158 higher than winter average. larger dimension, particles. addition, can characterize adsorption toxic harmful gases by well. provides parameter support for understanding effective atmospheric application values.

Fractal Population Ecology Theory
Abstract Purpose - The aim of this paper is to describe the population ecology theory through fractal thinking, an emergent human operating system that is creative, adaptive, healthy, and evolutionary; furthermore, a parallel is drawn between the population ecology model and the fractal structure. Top-down hierarchies are typically characterized by command and control systems of the authority t...
متن کاملGravitational Field of Fractal Distribution of Particles
In this paper we consider the gravitational field of fractal distribution of particles. To describe fractal distribution, we use the fractional integrals. The fractional integrals are considered as approximations of integrals on fractals. Using the fractional generalization of the Gauss’s law, we consider the simple examples of the fields of homogeneous fractal distribution. The examples of gra...
متن کاملCharacteristics of indoor and outdoor bioaerosols at Korean high-rise apartment buildings.
This study attempted to evaluate the bioaerosol exposure of apartment residents at high-rise apartment buildings in a Korean city. The characteristics associated with the bioaerosol exposure included the apartment floor, seasonal variation, summer survey period (seasonal rain-front period (SRFP) or no rain-front period (NRFP)), and room location inside an apartment. Four most prevalent fungal g...
