提高混匀矿质量生产实践

优化混匀矿配比、适时调整混匀矿堆计划、控制混匀矿中的SiO2是降低烧结矿原料成本,提高混匀矿稳定性的有效途径。通过采取将成分差异大的同一品种物料在一次料场分开堆放、优化4BLOCK计划、除尘灰按计划连续切出、增加停机程序等措施减少了混匀矿成分的波动;通过完善混匀工艺操作规程和管理制度,保证了混匀矿的正常有序生产,值得推广。

Experimental based comparative exergy analysis of a multi-cylinder spark ignition engine fuelled with different gaseous (CNG,HCNG, and hydrogen) fuels

The experimental investigation was carried out on a multi-cylinder spark ignition (SI) engine fuelled with compressed natural gas (CNG), hydrogen blended CNG (HCNG) and hydrogen with varying load at 1500 rpm in order to perform comparative exergy analysis. The exergy analysis indicates that work exergy, heat transfer exergy and exhaust exergy were the highest with hydrogen at all loads due to its high flame temperature, low quenching distance, and high flame speed. The engine's exergy efficiency was the highest with hydrogen (34.23%), and it was about 24.23% and 24.08% with CNG and HCNG respectively at high load (20.25 kW). This indicates a higher potential of hydrogen to convert chemical energy input of fuel into heat and then power output. The exergy destruction was observed minimum with hydrogen at all loads, and it was drastically reduced at high loads. The combustion irreversibility which was calculated using species present during combustion, was the main contributor to exergy destruction, and it decreased with hydrogen. The minimum combustion irreversibility was 11.75% with hydrogen, followed by HCNG and CNG with 16.46% and 18.88% respectively at high load. The high quality of heat due to high in-cylinder temperature and low entropy generation during combustion caused by less number of chemical species in hydrogen combustion are the main reasons for lower combustion irreversibility with hydrogen.     

基于超星学习通混合教学模式的应用研究

一般应用型本科高校采用传统教学模式进行材料类专业课程教学时面临诸多问题,教学质量的难以提升。本文基于超星学习通平台,利用其强大的交互功能,构建了一种基于“传递-接受”教学模式、“问答”型教学模式,“自学”型教学模式、“合作”型和“研究”型教学的混合教学模式,并进行了两年的实践应用研究。试验教学效果表明,与采用单一传统的“传递-接受”教学模式相比,基于超星学习通的混合教学模式,在提升学生的学习兴趣和提高教学质量方面起到了有益作用,对应用型本科高校理论课程教学模式的改革具有借鉴作用。
