Published: March 2020

Abstract
With the rapid economic development of Beijing-Tianjin-Hebei region, the problem of environmental pollution cannot be ignored. Especially in recent years, the haze weather, the increase of carbon dioxide emissions, the development of Beijing, Tianjin and Hebei has brought a negative impact. Now, the primary energy consumption of the three regions of Beijing, Tianjin and Hebei is decomposed into five factors including population, economy, industrial structure, energy intensity and energy consumption structure by using LMDI decomposition method. The results show that: overall population and per capita GDP promote the growth of carbon emissions, and overall industrial structure effect, energy intensity effect and energy consumption structure factors inhibit the growth of carbon emissions. The energy intensity of the secondary industry and the tertiary industry has a very significant inhibiting effect on the growth of carbon emissions.

Published: March 2020

Abstract
Large metal mines have many features of returning to the wind shaft and multi-level mining. The ventilation system is complex, and the ventilation conditions and external environment of each area are different. The general mine ventilation evaluation is for the entire mine system. It is not possible to accurately and specifically make specific evaluations and management recommendations for each part of the ventilation system. Taking the safety management research of the ventilation system of Huibaoling Iron Mine as an example, a regional evaluation method is proposed. An evaluation index system was established and evaluated for four different levels of regional ventilation systems in Huibaoling Iron Mine. The overall scores of each region and the scores of each indicator were used to provide a basis for specific safety management work. Field practice shows that regional ventilation management can solve ventilation management problems efficiently and in a targeted manner, and has good promotion and utilization value.

Published: March 2020

Abstract
In the closed-loop system of human-vehicle-road-environment, the environment has a very important impact on drivers. The long-term monotonous environment will lead to the visual fatigue of drivers, thus affecting the driving safety; while a good road landscape environment will give drivers a comfortable visual experience, which can relieve the visual fatigue of drivers to some extent. This paper takes the Impact of landscape color on the driving fatigue of drivers as the view of research and reflects the impact of landscape color on driving safety. This paper analyzes the basic attributes of color and analyzes the color fatigue characteristics of drivers using the spectral sensitivity (spectral luminous efficiency) function. Due to the uncertainty of the color attribute value of roadside landscape environment, the eye tracker is used to record the characteristics of the eye movement of drivers in the experiment. Also, based on the example of the landscape color of Qinghai-Tibet Highway, this paper selects the blinking frequency of drivers as the analysis index to quantitatively measure the driving fatigue of drivers, which can indirectly reflect the relationship between landscape color and driving safety.

Abstract
With 2 × 330MW subcritical coal-fired boiler as the research object, the influence of two kinds of primary air flue gas recirculation schemes on the combustion of pulverized coal and the formation of NOx were studied by numerical simulation software. The variation law of SCR inlet fume temperature was studied with boiler thermodynamic calculation. The calculation results show that the reasonable smoke mixing method can effectively improve the SCR inlet flue gas temperature and reduce the furnace outlet NOx concentration. The optimal proportion was 20% with the primary air mixing smoke while maintaining constant air mass. The results of numerical simulation and thermodynamic calculation show that SCR inlet flue temperature can be increased by 15°C, the concentration of NOx emission can reduce by 18.29mg/Nm3.

Authors: Sun Yongping , Wang Jigan , Li Yingqiu , Xing Zhencheng 
Published: March 2020

Abstract
Urban agglomeration has been the core of coordinated development of regional economy in China, since urban agglomeration is deemed as the main form of new urbanization by central government. The rapid industrialization in the Yangtze River Delta (YRD) brings about large consumption of water resources as well as massive industrial wastewater discharge. In this case, we incorporate industrial water consumption and wastewater discharges into the directional distance function to construct and analyze the industrial wastewater discharge efficiency (IWDE) of cities in the YRD. The results indicate that the overall IWDE in YRD proceeded in a fluctuation way during our study period. Also, IWDE varied among the cities in the YRD due to their spatial differences in economic development, water resource endowment and environmental regulation. In addition, there was an observed spatial cluster of IWDE among different clusters of cities in the YRD.

Published: March 2020

Abstract
Taking the flue gas recirculation system of 220MW coal-fired unit as the test object, effects of the operation mode of the flue gas recirculation system on the operating characteristics of the boiler under different working conditions was studied.The results show: the operation of flue gas recirculation system will suppress the amount of NOx generated in the furnace, and the best way to restrain the formation of NOx is to send the recycled flue gas into the furnace through primary and secondary air simultaneously. The flue gas recirculation system can effectively improve the inlet flue gas temperature of SCR, especially when the secondary flue gas recirculation system is put into operation, and the effect of increasing the inlet flue gas temperature of SCR is obviously better than that of the other two operation modes. The operation of flue gas recirculation system can effectively save net coal consumption.

Abstract
The reservoir of Tongluomiao Temple in Surenuoer Oilfield is dominated by glutenite. The sand body is dense, the buried depth is shallow, the heterogeneity is strong, and the oil-water relationship is complex. The favorable reservoir sand body prediction has always plagued the block exploration and development. Therefore, based on the seismic waveform indication inversion principle, process and key parameter settings, based on the petrophysical analysis in the study area, the reservoir inversion technique is studied, and the well interpolation model and the waveform indication inversion model are proposed. The method generates the inversion prediction model of the study area. On this basis, the threshold value of the layer is used to extract the thickness distribution of the sand body plane, and then the favorable target area is predicted. The actual drilling results show that the thickness of the sand body predicted by the method and the actual drilling The results are in good agreement and the oil and gas shows good, providing a reliable technical method for reservoir prediction.
