China’s energy carbon emissions are projected to peak in 2030 with approximately 110%of its 2020 level under the following conditions:1)China’s gross primary energy consumption is 5 Gtce in 2020 and 6 Gtce in 2030;2)coal’s share of the energy consumption is 61%in 2020 and55%in 2030;3)non-fossil energy’s share increases from 15%in 2020 to 20%in 2030;4)through 2030,China’s GDP grows at an average annual rate of 6%;5)the annual energy consumption elasticity coefficient is 0.30 in average;and 6)the annual growth rate of energy consumption steadily reduces to within 1%.China’s electricity generating capacity would be 1,990 GW,with 8,600 TW h of power generation output in 2020.Of that output 66%would be from coal,5%from gas,and 29%from non-fossil energy.By 2030,electricity generating capacity would reach3,170 GW with 11,900 TW h of power generation output.Of that output,56%would be from coal,6%from gas,and 37%from non-fossil energy.From 2020 to 2030,CO2emissions from electric power would relatively fall by 0.2 Gt due to lower coal consumption,and relatively fall by nearly 0.3 Gt with the installation of more coal-fired cogeneration units.During 2020e2030,the portion of carbon emissions from electric power in China’s energy consumption is projected to increase by 3.4 percentage points.Although the carbon emissions from electric power would keep increasing to 118%of the 2020 level in 2030,the electric power industry would continue to play a decisive role in achieving the goal of increase in non-fossil energy use.This study proposes countermeasures and recommendations to control carbon emissions peak,including energy system optimization,green-coal-fired electricity generation,and demand side management. China’s gross energy consumption is 5 Gtce in 2020 and 6 Gtce in 2030; 2) coal’s share of the energy consumption is 61% in 2020 and 55% in 2030; 3) non-fossil energy’s share increases from 15% in 2020 to 20% in 2030; 4) through 2030, China’s GDP grows at an average annual rate of 6%; 5) the annual energy and 6) the annual growth rate of energy consumption steadily reduces to within 1% .China’s electricity generation capacity would be 1,990 GW, with 8,600 TW h of power generation output in 2020.Of that output 66% Electricity generation capacity would reach 3,170 GW with 11,900 TW h of power generation output. Of that output, 56% would be from coal, and 29% from non-fossil energy. By 2030, 6% from gas, and 37% from non-fossil energy. Flash 2020 to 2030, CO2emissions from electric power would rel atively fall by 0.2 Gt due to lower coal consumption, and relatively fall by nearly 0.3 Gt with the installation of more coal-fired cogeneration units. Drawing 2020e2030, the portion of carbon emissions from electric power in China’s energy consumption is projected to increase by 3.4 percentage points.

摘要模拟法庭教学作为提高法学本科学生法律综合技能的一种行之有效的教学方式得到各法学院系的重视,同时也受到法学本科学生的欢迎。模拟法庭教学具有提高学生法律职业技能、职业道德以及社会认知能力的功能,要使模拟法庭真正发挥以上功能还必须从制度、模拟法庭建设及教师的选任上下功夫。遵循具体的程序完成模拟法庭教学的实施,并在实践中不断修正充实。  中图分类号:G427文献标识码:A    依法治国,建立社会主义
