Some topics on charmonium decays at BESⅢ experiment

The construction of BESⅢ detector has been finished and the data taking is under plan. Some physics topics on charmonium decays at BESⅢ experiment are discussed in this paper. The measurement of properties of η_c and η_c at BESⅢ is discussed and the expected precision of the measurement is estimated based on BOSS. Also the χ_cJ decay and the measurement of hyperon decay parameters are mentioned.     

新课标背景下的教学、学法的探究

本文针对新课标背景下的教学、学法进行探究。内容主要从三个方面进行具体论述:一、重视学生个性发展和创造精神。二、激发学生积极思维的契机,培养学生“自主”学习的能力。三、建立民主、平等的和谐师生关系。
