In this paper, ethnic minorities refer to the 55 minorities other than the Han ethnic group with- in the borders of the People＇s Republic of China; human rights mean the human rights connotations within the ken of international human rights laws; legal principles mean the principles that all authoritative organizations, legislative organs, administrative departments, judicial organs and other departments should obey.

EXPERIMENTAL STUDY ON THE MACRO-AND MICRO- CHARACTERISTICS OF THE SPRAY FROM A PRESSURE SWIRL NOZZLE

The experimental study on the macro and micro characteristics of the spray from a pressure swirl nozzle embraces the growth of surface unstable wave,disintegration process,spray angle,breakup length and so on.The effects of injection pressure,nozzle geometry and liquid properties on these characteristics are also discussed.The results are helpful to understand the underlying physics of the pressure swirl nozzle and serve as the basis for the practical design,usage and improvement of the nozzle.

The Influence of Acid on the RockMechanical Characteristics of Deep Shale in theWujiaping Formation

The microscopic characteristics and mechanical properties of rocks change after the action of acid on deep shale,which affects the fracturing effect.Accordingly,we designed and conducted indoor experiments related to the changes in macro and microscopic characteristics after the interaction of acid with the shale of Wujiaping Formation,based on which the characteristic law of fracture volume modification after acid fracturing was studied using numerical simulation.The results demonstrate that the pores and fractures are enlarged and the structure is significantly loosened after the acid immersion.And a 15%concentration of hydrochloric acid can effectively dissolve shale.Furthermore,the degree of acid-etching reaction is highly variable because of the different carbonate content,which reveals the strong inhomogeneity of the shale system in the Wujiaping Group reservoir section.After the acid interacted with the shale rock samples,the triaxial compressive strength,elastic modulus,and Poisson’s ratio of shale decreased.Moreover,the evaluation of the effect after acid fracturing simulated by fracturing software revealed that the smaller the value of elastic modulus in shale-based reservoirs,the more favorable the fracture volume modification.This discovery not only provides a theoretical basis for the expansion and extension patterns of acid-fracturing in carbonaceous shale formations but also offers research methods and theoretical insights for the fundamental exploration of other deep-seated oil and gas resources.

Analysis of the Rapid Intensification of Typhoon “Mekkhala” (2006) over the Offshore Area Based on Satellite Data

Analysis of the cloud macro characteristics of typhoon “Mekkhala” is based on FY-4A stationary meteorological satellite data. Aiming at the precipitation process during the “Mekkhala” tropical storm and typhoon, the precipitation structure characteristics were analyzed using the precipitation data retrieved from polar orbiting satellites. The results show that: in the life process of “Mekkhala”, its cloud system always presents an asymmetric structure, and the cloud area and cloud top height on the north and south sides also change constantly. When the intensity of “Mekkhala” reaches the maximum, its minimum brightness temperature range is also the largest, and the spiral structure is also the most obvious;during the precipitation process of the “Mekkhala” tropical storm and typhoon, the near-surface precipitation rate is roughly distributed in a ring shape, from the precipitation rate of the FY3-D polar-orbiting satellite and the GCOM-W1 satellite. In terms of product comparison, the precipitation rate product of the GCOM-W1 satellite responds better to low-level precipitation.
