采用rutter儿童行为问卷(教师问卷) 、父母养育方式评价量表( embu ) 、小学生生活事件问卷等多种工具综合测量小学生的社会心理状况，并用多元逐步回归分析方法对影响小学生行为问题的社会人口学、心理社会因素进行探讨，同时对小学生自杀意念进行研究分析，通过多因素条件logistic回归模型，筛选出自杀意念的主要危险因素，以期为提高小学生的心理健康水平服务，为素质教育提供科学依据。 - The static and dynamic characteristic models of stage are built by ansys , which analyses the displacement , stress , natural frequency and vibration model of stage . furthermore , the influence of primary structural parameters on static and dynamic characteristic is analyzed by orthogonal experimental scheme comprehensively and the numerical results from experiment are regressed by stepwise regression method , thus the optimization regression equation is obtained . meanwhile , the neural network model is built and validates the regression model
应用ansys软件建立了工作台静、动态特性的分析模型，并分析了工作台的位移、应力以及振动的固有频率和振型，而且还应用正交试验表安排参数全面分析了结构参数对微位移工作台的静、动态特性的影响，并用逐步回归分析方法对数值计算结果进行回归，获得了微动工作台的最优回归方程，同时建立了人工神经网络模型并对回归模型进行了验证。 - This paper mainly carries on research into quantity , degree and depth of luc , and landscape change degree in different economic zones of chongqing , comparative study of human driving forces causing different luc from qualitative and quantitative respects in different economic zones of chongqing , further investigation with cultivated land change and construction land change and driving force through analyzing proper human driving forces using principal components " analysis , multi - linear regression model , stepwise regression model , quantitative prediction of cultivated land and construction land in the following 10 years in the sample areas with the help of grey trend prediction model such as gm ( 1 , 1 )
本研究主要进行了不同经济区土地利用变化数量、变化程度(速度、速率) 、深度以及景观变化差异研究；从定性和定量两个方面对引起不同经济区样点土地利用变化差异的人类驱动力进行对比性研究；通过选取适当的人类驱动力因子，利用主成分分析法、多元线回归模型、逐步回归分析法对人类驱动力所引起的不同经济区的耕地、建设用地的土地利用变化进行深入研究；利用灰色动态预测模型gm ( 1 ， 1 )对未来10年内样点区耕地、建设用地变化进行预测性研究。 - The one - way anova analysis and correlation analysis show that the factors such as country or town , family structure , family economic level , mother ' s education , mother ' s occupation , father ' s warmth and empathic relationship , mother ' s warmth and empathic relationship , mother ' s over - protection and over - interference and family communication have notable correlations with the self - efficacy of middle school students . multiple linear regression analysis shows that some external factors including mother ' s occupation , family structure and family economic level , some internal factors such as mother ' s warmth and empathic relationship , mother ' s severe punishment and family communication have notable influence on middle school students " self - efficacy . and family economic level may also influence self - efficacy by influencing mother ' s parenting style and family communication
单因素方差分析和相关分析表明，来自农村城市，家庭结构，家庭经济状况，母亲文化程度，母亲职业，父亲温暖理解、母亲温暖理解、母亲过干涉过保护，家庭沟通等都与中学生自我效能感有显著联系；多因素逐步回归分析表明，母亲职业、家庭结构、家庭经济状况等外环境因素以及母亲温暖理解、母亲惩罚严厉，家庭沟通等家庭内环境因素对中学生自我效能感有显著的预测作用；其中家庭经济状况还可以通过对母亲教养方式和家庭沟通的影响间接影响中学生自我效能感。 - The patent application acceptance and awarding of university was studied in this paper , including patent , utility model and industrial design between 1986 and 2001 , and the comparative studies with other trades have been carried out ; investigations were done on the relationship between university patent applications , the number of researchers and inventors , application of r & d advances , number of technical service personnel , investment of scientific research funds , patent transfer , number of research and development projects , and number of scientific and technological achievement awards in universities ; 547 staff members of the central south university completed the questionnaire ( 32 questions ) regarding the intellectual property right , knowledge of patents , awareness of patent protection and patent - related behaviors , those people were distributed in the departments of teaching , research , administration and management , and teaching support ; one - way anova , multivariate analysis of variance manova and linear correlation methods were used in the analysis of research - related factors concerning central south university staff members and their understanding of intellectual property right , knowledge of patent , awareness of patent protection and patent - related behaviors , the major factors affecting university patent application , awarding and transfer were identified ; countermeasures to promote university patent development in china were also proposed
本研究旨在通过对1986年? 2001年我国高校发明专利、实用新型、外观设计的申请受理与授权情况的分析，并且与其他行业的比较；通过研究我国高校专利申请与高校研发人员数、 r & d成果应用及科技服务人员数、科研经费投入、高校专利转让、研究与发展课题数、科技成果获奖数的关系；通过对中南大学547名教学、科研、党政管理、教辅人员的产权知识、专利知识、专利意识、专利行为的问卷调查(共32题) ，并用单因素分析法、多元逐步回归分析法和线性相关分析法，对中南大学在职人员各研究因素与产权知识、专利知识、专利意识、专利行为的统计分析，寻找出制约我国高校专利申请、授权、成果转让的因素，提出加速发展我国高校专利工作步伐的对策。
