Study on Decoupling Relationship Between Carbon Emissions of Agricultural Water Consumption and Agricultural Economic Growth in Hangzhou and Its Driving Factors by ZHANG Qing, ZHU Hua, WANG Yan, XU Rouyi, CHEN Jiexun, YE Jinyang

“…Understanding the relationship between carbon emissions of agricultural water consumption and agricultural economic growth is of great significance for the efficient utilization of water and energy resources in agriculture and the development of the regional low-carbon economy.Agricultural-related statistical data in Hangzhou from 2010 to 2021 are utilized to calculate the carbon emissions of agricultural water consumption.The decoupling relationship between carbon emissions of agricultural water consumption and agricultural economic growth in Hangzhou is explored.The results show that:①From 2010 to 2021,the carbon emissions of agricultural water consumption in Hangzhou show a non-stationary decline trend,and the intensity of carbon emissions shows a continuous decrease trend,with reductions of 0.82×10⁸ kg and 1.14 t/10⁴ yuan (the Chinese currency),respectively.The temporal evolution of carbon emissions of agricultural water consumption can be roughly divided into three stages:“decrease firstly and then increase,decline with fluctuation,and relatively stable”;②The decoupling relationship between carbon emissions of agricultural water consumption and economic growth in planting industry in Hangzhou from 2011 to 2021 is mainly characterized by strong decoupling,accounting for 72.73%;③Technological effects and economic effects are the main factors promoting and inhibiting the decoupling between carbon emissions of agricultural water consumption and economic growth.…”

Research on transient energy suppression strategy of intrinsically safe output power supply for mine by Changna GUO

“…In response to the requirements of GB/T 3836.4—2021 Explosive atmosphere Part 4: Equipment with protection by intrinsic safety “i” for outputting transient energy of intrinsically safe power sources based on the principle of semiconductor rapid short circuit protection, taking typical mining “ib” class explosion-proof and intrinsically safe power supplies and intrinsically safe battery power supplies as research objects, the study clarifies the transient energy testing device and transient energy calculation method. According to the experimental verification and comparison, the reasons for the failure of the transient energy experiment of the output intrinsically safe power supply are analyzed, and it is verified that the protection time, the reaction speed of semiconductor chip, the short-circuit instantaneous voltage and current value in the over-voltage and over-current protection circuit are the key parameters affecting the transient energy; based on the actual design, the protection process is analyzed, the method of reducing transient energy by TVS tube is excluded, and the influence of inductor on transient energy before and after the power supply overvoltage and over-current protection circuit is studied, which provides a reference for the design of the output intrinsically safe power supply for mining.…”
