摘要:
近年来,各大高校都在进行大学英语教学改革,如削减学分、压缩课程等。面对这一形式,大学英语教学改革迫在眉睫。本文拟将通过大学英语课文Slavery Gave Me Nothing To Lose进行教学设计和课堂组织,展示如何运用人文主义理念,实现英语教学的人文性和工具性统一,又服务于专业需求,为大学英语教学改革开创新道路。

摘要:
To improve the using life of screw, the paper focused on the research about microhardness and wear resistance of surface detonation spraying coat. The detonation spraying surface was important to extend the wear resistance of screw of low temperature screw press machine. The paper analyzed the phase composition and microstructure data of surface detonation spraying coat and tested the microhardness of coat and combination intensity between coat and substrate, and did contrasting wear resistance experiment between detonation spraying coat and traditional coat. The data analysis results showed that the wear resistance of detonation spraying coat was far beyond traditional coat and the detonation spraying coat would improve the using life of key screw of low temperature screw press machine.
