Using the material of hydrology in the upper Yangtze River and the runoff, the temperature, and the precipitation observed in meteorological stations from1956 to 2004, the intermonthly and interdecadal evolution characteristics of the runoff and the sudden change characteristic in the area are analyzed by the climatic diagnosis method.
In terms of the analysis on the sedimentary facies of typical and connecting wells in different areas and facies belt, together with the Neogene tectonic evolution characteristics of foreland basin, the distribution and evolution of the sedimentary facies of the study area have been clearly discovered both vertically and laterally.
The formation cause of shoal and evolution characteristics of the section are discussed, and the regulation principle, regulation scheme of the river section, as well as the regulation effect after implementation of the project are expounded with emphasis.
Based on the analysis of hydrodynamics and river-bed evolution, this paper reveals the formation causes and evolution characteristics of the shoal, determines the regulation principle and method, and carries out comparative study on several regulation schemes through river engineering model test, according to which, the small curvature scheme was selected at last.
Comparing the Evolution Characteristics of Waves in Nonlinearly Elastic Micro- and Nanocomposites with Carbon Fillers
As poly(vinyl chloride) becomes more popular as a building material and electrical insulation, it becomes more important to life safety to determine its smoke and hydrogen chloride evolution characteristics during pyrolysis.
Distinct evolution characteristics of bubble in 3D and 2D simulation are further discussed.
Electrochemical and gas evolution characteristics of direct methanol fuel cells with stainless steel mesh flow beds
The bubble evolution characteristics (i.e., size and frequency) which affect mass transfer and cell voltage were also evaluated.
