The second metamorphic event took place at about 2000Ma. Its peak P-T condition is 800±20℃ and 0. 53-0. 68GPa. The P-T-t path in the second stage of metamorphism is a kind of evolution pattern which typically belong to erogenic belt.
We analyze the sustaining evolution pattern of composite system of regional land and resources with the growth curve of development system, and discuss the ways of the realization of sustainable development for the system.
The essay analizes the definition of the sustainable development by the world environment and development committee and points out that that the sustainable development is the coordinating operation of the regional PRED system and the development of the stabe increase of social welfare and fair distribution. After analizing the elemental features and functions of the regional PRED system, it points out that the evolution pattern of the regional PRED system is a group of composed logical curves.
The seismic spectral decomposition technology is a new seismic imaging analysis method based on the spectral analysis technology, it can reveal the changing law of stratigraphy in vertical direction and 3-D evolution pattern of sedimentary facies. The quantificational description and analysis are carried out from reservoir to single sand set unit.
By means of analysing samples of slurry water in the construction of embankment and hydraulic fill at the Taicang Port,the mud diffusion and the evolution pattern is studied in the process of project construction.
The characteristics and process of the information transmission are also expounded, which is of significant importance for understanding the formation mechanism, evolution pattern, and developing trend as well as for setting up models for restoration and rebuilding of the degraded ecosystem.
By a comprehensive analysis of the proxy indices of climate such as readily soluble salt and spore-pollen of borehole profiles in Dougeyong Basin,the palaeoclimatic evolution pattern of the Yellow River source area since 130 ka B P has been revealad:1.From 130 ka B P to 110 ka B P,it was cold and dry;
The concept of "spirit-resonance life-movement", in its thousand years process of development, has gained new significance, revealed the evolution pattern of the Chinese painting, as well as the tendency of the development of the spirit of ancient Chinese art.
The microstructure evolution pattern of undercooled Cu-40wt%Pb(mass percentage)tennary alloy has been investigated with glass fluxing technique combined with cycling processes of superheating and cooling.
Evolution pattern of solidification microstructure in the monophase Cu Ni alloy in the range of thermo dynamically supercooling of 63～292 K is investigated, and both the condition of supercooling degree and orientation mechanism and control method of directional crystalline growth in the melt under negative temperature gradient are analyzed.
The model predicted a steady state CO2 evolution pattern for the destruction process during continuous organic feeding.
Quantitative results obtained from investigations of the evolution pattern of the defect subsystem formed under fatigue loading are examined.
This evolution pattern is mimicked by diazoxide and abolished by 5-hydroxydecanoate.
Indeed, the evolution pattern of bioenergetic features changes with the type of mutation and with the introduction of ethylene into an ethylene-synthesis-deficient tomato fruit mutant during its induced ripening.
The evolution pattern and the stand structure were affected by thinning, which resulted in the improvement of tree quality and growth and accelerated their early fruition, thus contributing to higher ecosystem resilience.
