摘要：The partial coal gasification air pre-heating coal-fired combined cycle (PGACC) is a cleaning coal power system, which integrates the coal gasification technology, circulating fluidized bed technology, and combined cycle technology. It has high efficiency and simple construction, and is a new selection of the cleaning coal power systems. A thermodynamic analysis of the PGACC is carried out. The effects of coal gasifying rate, pre-heating air temperature, and coal gas temperature on the performances of the power system are studied. In order to repower the power plant rated 100 MW by using the PGACC, a conceptual design is suggested. The computational results show that the PGACC is feasible for modernizing the old steam power plants and building the new cleaning power plants.

摘要：Concern about global warming calls for an advanced approach for designing an energy system to reduce carbon emissions as well as to secure energy security for each *** energy systems tend to introduce different technologies with high conversion efficiency,leading to a higher average *** energy systems can be achieved not by an aggregate form of conversion technologies but by an innovative system design *** concept of LCS(low carbon society) is a unique approach having multi-dimensional considerations such as social,economic and environmental *** LCS aims at an extensive restructuring of worldwide energy supply/demand network system by not only replacing the conventional parts with the new ones,but also integrating all the necessary components and designing absolutely different energy *** a core tool for the LCS design,energy-economic models are applied to show feasible solutions in future with alternatives such as renewable resources,combined heat and power,and smart grid *** can introduce changes in energy markets,technology learning in capacity,and penetration of innovative technologies,leading to an optimum system configuration under priority *** paper describes recent trials of energy models application related to waste-to-energy,clean coal,transportation and rural *** the modelling approach is still under investigation,the output clearly shows possible options having variety of technologies and linkages between supply and demand *** of the LCS means an energy systems design with the modelling approach,which gives solution for complex systems,choices among technologies,technology feasibility,R&D targets,and what we need to start.

摘要：PEP《英语》四年级上册学到clean这个单词,用作动词,意思是“打扫、清扫”的意思。clean有哪些用法呢?***用作动词clean用作动词的意思是“使清洁;变干净”,引申可作“清扫”解。如:Let's clean the classroom.(让我们打扫教室。)Let me clean the window.(让我擦窗户)。***用作形容词clean用作形容词的意思是“清洁的,干净的”,也可以表示“诚实的、纯洁的、整齐的”等意思。如:The sky is blue and the air is clean(天空是蓝色的、空气是干净的。)You should keep your room clean.(你应该保持房间整洁。)

摘要：一、案例背景在小学英语课堂上,教师喜欢给学生呈现解决问题的情境,利用所提供的场景和已知有关经验和知识,完成学习任务。但是很多教师往往忽略了教学活动中的评价过程。根据新课程理念,科学的、合理的、有效的、及时的评价能促进教学和学习,充分体现学生为主体的价值需要。如何让学生积极地参与评价,了解自己的不足和差距,及时改正学习是教师们在教学过程中需要思考的问题。我以牛津小学英语六年级上册Unit 6“Keep our city clean”（story time）进行实践,设计了下面的案例。
