The macroscopic conditions for the formation of hail clouds are discussed through analyzing the patterns, thermal and hygrometric stratification conditions and local features of mesoscale influencing systems occurred in severe hail days from 1980 to 2000 in the Beijing area.
Aimed at the typical complex strata,the finite element method and resistivity imaging technique are applied in the paper to deal with the analysis and simulated measurement of stratification and fracture,and the simulated imaging results are used to reflect the real formation information directly.
The bioclastic micrite limestone in shale strata of the lower Meitan formation in Wudang,Guiyang is a complete tempestite layer. Its thickness is about 130cm and its sedimentary sequences can be divided from bottom to top into six sections, Section A being grained sequence , Section B being massive; Section C being parallel bedding, Section D being hummccky cross stratification, Section E being wave ripple and Section F being pelitic.
According to the project practice, the paper states the key technical problem in the excavated hole of pile pier treated by "composite working method", when pile pear foundation adopts the construction method of digging and building by short sector in different stratification structural types of complex soil stratums.
The natural gradation、stratification、jointof、fracture of rock is used to suitably determine the direction of blasting and hole pattern in the course of mining stones for Chaishitan reservior engineering, and ideal blasting effectiveness is achieved.
A Deodhar-type stratification on the double flag variety
This partition is a refinement of the stratification into orbits both for B+ × B- and for the diagonal action of G, just as Deodhar's partition refines the orbits of B+ and B-.
The thermal-rheological stratification structures of the lithosphere in the East Qinling orogenic belt present different features from each other within different tectonic units.
The results of analysis of the proteomes of the axes and cotyledons have been studied and the effects of the stratification have been assessed.
Gene expression has been studied at the level of protein synthesis: the protein-synthesizing capacity of the cells of the embryonic axis and cotyledon storage parenchyma of mature seed and seed undergoing stratification.
