This study gathered and processed the available air quality daily reports in 86 cities throughout China 2001-2011. Urban was assessed terms of evolution key pollutants, pollution level, PM10 (particulate matter with an aerodynamic diameter < 10 microm) concentrations. The authors conclude that is most important pollutant Chinese cities, especially after national sulfur dioxide (SO2) controls during 11th Five Year Plan (FYP; 2006-2010). A notable advance reduction extremely heavily polluted...
The Southern Hebei of China has experienced an obvious increase the haze occurrence frequency in recent years. It turned out to be one most seriously polluted areas China. This study is aimed at quantifying sources serious pollution over area, using Mesoscale Modeling System Generation 5 (MM5) and Models-3/Community Multiscale Air Quality Model (CMAQ) modeling system. sectoral contributions by local surrounding regions fine particulate matter (PM₂.₅) concentrations two representative cities,...
How to predict precipitation accurately and efficiently is the key difficult problem in field of weather forecasting. At present, we can obtain accurate meteorological data through many high-precision sensors use them forecast precipitation. However, common numerical forecasting methods radar echo extrapolation have insurmountable defects. Based on some characteristics data, this paper proposes a Pred-SF model for prediction target areas. The focuses combination multiple modal carry out...
The aim of this paper is to analyze the dependence structure between asset returns using extreme value copulas. We first focus on use theory, more specifically, generalized distribution (GEV) model tail behavior financial return series based monthly maxima and minima daily USD/UK, USD/EUR foreign exchange data. A parameter estimation maximum likelihood method proposed for GEV model, basis which, we conduct statistical copula parameters Inference Margins (IFM) method. thereafter identify...
Snow is an important component of the Earth's surface.The accuracy satellite-derived snow cover area products for water management and modeling hydrological climatic processes.In paper,the MODIS products(MOD10A1 MOD102)and VEGETATION products(VGT-S10 products)algorithm under varied terrain land types were analyzed using in situ observation data at 47 stations northern Xinjiang area,China,during five seasons including January 1 to March 31 2001 each November 2005.The research result indicates...
Several gold ore-concentrated areas have been recognized in the destruction zone of North China Craton (NCC). However, deposits western part received less attention. Miaoan, a typical Au-polymetallic deposit northern Taihang Mountain, provides good sample for deepening our understanding genesis zone. In this study, detailed ore geology, pyrite Rb-Sr age, trace element and S-C-O isotopes Au-bearing ores were conducted to constrain source ore-forming materials their tectonic setting. The...
The organic carbon isotopes of the Luochuan section show that δ13C values vary from-18.7‰ to-23.5‰,and downcore distribution isotope could be divided into three stages with similar trends magnetic susceptibility in glacial-interglacial scales.The results demonstrate 1) vegetation coverage area was mainly a mixture C3 and C4 grassland,2) value loess sequence better recorded summer monsoon change scales just as trend.Comparing Duanjiapo Weinan sections,two times evident transition on tectonic...
The wave parameter is an important environmental input condition. Traditional contact measurement methods are unable to meet the requirements of high precision, non-contact, and ship field assessment. Alternatively, stereo vision technology can realize a non-contact mobile form measurement. However, this suffers from poor timeliness adaptability. This paper proposes comprehensive method that based on vision, wherein gridding siftGPU used achieve fast matching large images. whole algorithm be...
In China, sintering flue gas has become the most important source of air pollution rather than burning coal-fired gas.The emission characteristics and removal efficiencies various gaseous pollutants were studiedon a 180 m2 equipped with semi-dry oxidative desulfurization denitrification system in Tangshang, Hebei province. The concentrations particulate matter, fluoride,NOX SO2were measured whilepolychlorinated dibenzo-p-dioxins dibenzofurans(PCDD/Fs) tested both dust ash at 100% 60%...
