Cu2ZnSeS4(CZTS)is a new type of thin-film solar cell whose band gap is 1.4~1.51 eV,while absorbing the sunlight requires the best width range of the band gap of materials is from 1.4 eV~1.6 eV.The band gap range matches the terrestrial solar spectrum,and its optical absorption coefficient exceeds 104 cm-1.Because of the previous absorbing layer use the toxic or trace elements,but the CZTS solar cells have the advantages of low cost,high efficiency,safety and nontoxicity,which is incomparable for other solar cells.So it will became the mainstream of the future which is use for the solar cell absorbing layer.

摘要：高中语文属于重要的学科之一，也是我国升学考试的主要学科，其课堂教学一直备受关注。随着新教育改革越来越深入，传统灌输式教学模式已经很难满足高中语文素质教育的要求。在此背景下，师生合作式教学模式应运而生。该教育模式重视教师与学生之间的互相合作，以提升学生的学习效率。 关键词：高中语文；师生合作；课堂教学；质量 中图分类号：G633.3 文献标识码：A 文章编号：1992-7711（2017）

摘要：在教学中，我们发现学生随着年龄的增长，提问却越来越少。针对许多学生问题意识随之长大而逐渐缺失的现象，本文提出了相应的解决策略。 关键词：问题意识；策略；研究 中图分类号：G632.0 文献标识码：A 文章编号：1992-7711（2017）02-0003 陶行知先生说过：“创造始于问题。”哲学家波普尔曾说过：“正是问题激发我们去学习，去发展知识，去实践，去观察。”但纵观我们目前的教学，
