The weathering crust of carbonate is of big buried depth,anisotropy,serious heterogeneity and complicated reservoir forming condition. This study applies various techniques,including the comprehensive techniques for analysis of seismic attributes、the 3-D coherent analysis、the spectral decomposition technique、the 3-D visualized technique etc. ,to comprehensively analyze various seismic attributes of the weathering crust of carbonate and studied the method that is applied to predict the distributing law of the weathering crust of carbonate reservoirs in Tarim basin.
The model emphasizes the integration of theory and practice teaching systems, with the cultivation of technology application ability as its center, with the cultivation of core technology comprehensive application ability as its focus, combining theory with experiments and practice training, which is beneficial to strengthen the higher vocational students' practical ability, especially the cultivation of comprehensive technology application ability.
The relation of composition and structure to chemisorption and catalytic pro-perties of CuO-ZnO-Al_2O_3-V_2O_5 catalyst have been investigafed by using of XRD,AES,XPS,EPMS,chemisorption and microreactor technique Based on the experimental results,a new active-unit model of the catalyst is proposed.
For the optimization of radiation parameters as well as plasma properties investigation in the PF discharge it is necessary to use comprehensive techniques for studies of plasmas.
Perturbation approaches can be used to introduce finite rate chemistry effects, particularly where a distinct chemical time-scale separation is present, though more comprehensive techniques, e.g.
Corrugated wall horns and smooth wall multimode horns are two comparatively ideal feeds with high efficiency. Further study on mode conversion between the two types of horns is presented. The concept of combining hybrid mode technology for corrugated wall with multimode technology for smooth wall in one horn is suggested. An engineering design method for using it to control the characteristics of different frequency zones respectively is depicted. The complex multimode horn which is of small size, good perf...
Instrumentation technique for determining the surge point of a twin-shaft turbojet engine on ground test bed is presented in this paper. The effectiveness of two surge-inducing methods used in the test is also described in the paper. A practical fuel flow step unit is introduced and the surge point measurement and the trace analysis of engine operating point are discussed.Typical oscillograms are given which were taken when the engine was surging or not surging during the fuel flow stepping. When the engine...
It is proved that the analytization and synthetization of natural sciences, especially of biology are making agriculture totality theory rise from abstract to concrete synthesis, or from philosophical to systemic synthesis, and are therefore laying the scientific foundation of agriculture transition from the industrialization to the synthetization and biologicalization, i. e. the synthetization of physical, chemical and biological technology of agriculture.
