谈成人教育质与量的协调并进

质与量是一对矛盾的统一体,它们相互排斥,相互制约,且又互为衡量的尺度。成人教育的质与量反映在多个方面,如教师队伍的质与量;课程配置及教学设施的质与量;课堂教学与科研实践的质与量;成教培育出的人才的质与量等等。关于成人教育的质量,目前尚无能客观有效地反映成人特点的评估标准,大多参照同类普通高校的评估标准。不能否认,这对成人教育有欠公平,但笔者不准备探讨适合成人教育的质量评估标准,本文将重点讨论如何根据成人学生的特点,因势利导保证课堂教学的质与量协调并进

The Properties of Liquid Crystals in an External Field

通过求解包含外场的自治场方程，研究了液晶物质在外场中的物理性质.得到了包含外场的lAndAu-dEgEnnES自由能和由微观理论推导出来的COTTOn-MOuTOn常数.同时研究了由外场诱导出的临界现象，并给出了临界参数.The physical properties of liquid crystals in an external Field were investigated by means of solving the equation of a selF-consistent Field including an external Field, Landau-Gennes Free energy including an external FieId and Cotton-Mouton constant derived From microscopic theory were obtained.Meanwhile the critical phenomena induced by the external Field were studied and the critical parameters were also obtained

Analysis 0f ReIation between Enetgy Resources Consumption and Economic Development

以1978--2006年的年度中国能源消费总量与实际 GDP 的数据为依据,运用协整分析、误差修正模型和Granger 因果关系检验方法,检验我国能源消费总量和国内生产总值之间的关系。实证表明,尽管在短期内,能源消费与 GDP 之间的关系起伏波动,但是长期看,经济增长与能源消费之间具有相对稳定的关系,且存在从经济增长到能源消费单向因果关系。我国应当建立与完善能源生产消费监测和预警机制,提高能源利用效率,鼓励开发新能源,加大能源开发力度,优化能源结构,加快经济结构向能源集约化和节约型的转变。Based on data of total amount of energy resources consumption and real GDP from 1978 to 2006,checked relations between energy resource consumption and GDP in terms of cointegration analysis,error correction model check- ing method of Granger relation between cause and result.It showed that although relations between energy resource con- sumption and GDP fluctuate in short period of time,in long term the relation is relatively stable,and the relation between economic increase and energy resources consumption is that of cause and result.We should establish and perfect super- vising and early warning mechanism of energy resources production and consumption,raise utilization ratio,encourage developing new energy resources,making more efforts to develop new energy resources,optimize structure of energy re- sources,and speed up economic structure transferring into intensive and economical type of energy resources
