his paper explores the 12 aspects of geo-environment and construction engineering, including the earth evolution, the structure of geological bodies, the comprehensive utilization of resources, the ge...
Construction of non-diagonal background error covariance matrices for global chemical data assimilation
Chemical data assimilation To optimize the noise Model predictions Chemical state
2014/12/9
Chemical data assimilation attempts to optimally use noisy observations along with imperfect model predictions to produce a better estimate of the chemical state of the atmosphere. It is widely accept...
Design and construction of a simple Knudsen Effusion Mass Spectrometer (KEMS) system for vapour pressure measurements of low volatility organics
Design construction Knudsen Effusion Mass Spectrometer (KEMS) system vapour pressure measurements
2010/2/8
A design of and initial results from a Knudsen Effusion Mass Spectrometer (KEMS) are presented. The design was adapted from high temperature alloy studies with a view to using it to measure vapour pre...
A step-by-step procedure for pH model construction in aquatic systems
step-by-step procedure pH model construction aquatic systems
2010/1/15
We present, by means of a simple example, a comprehensive step-by-step procedure to consistently derive a pH model of aquatic systems. As pH modelling is inherently complex, we make every step of the ...
AbstractThe factor of human projectactivity is often the immediate cause resulting in soil and water loss． The Baoji-Lanzhou second railway inconstruction is an example．The soil and water loss law cau...
Hazard connected to railway tunnel construction in karstic area:applied geomorphological and hydrogeological surveys
railway tunnel construction karstic area geomorphological and hydrogeological surveys
2009/12/25
In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater...
