Operational Patterns of Industrial Symbiosis Network in Industrial Cluster District Based on Circular Economy Theory

Industrial symbiosis network （ISN） is an efficient organizational form for improving resource recycling and efficiency in industrial cluster district. Because of the variety of industrial cluster district formation model, the industrial symbiosis network is different with each other. Based on the circular economy theory, combing with international tendency of cluster district, the paper puts forward the relying-on-oriented industrial symbiosis network. Meanwhile, it also analyzes its organizational mechanism, operating pattern and environmental performance. Through the above efforts, we hope it could be helpful for industry cluster district sustainable development in China.     

Stability analysis of the simplest Takagi-Sugeno fuzzy control system using circle criterion

A frequency-domain-based sufficient condition is derived to guarantee the globally asymptotic stability of the simplest Takagi-Sugeno (T-S) fuzzy control system by using the circle criterion. The analysis is performed in the frequency domain, and hence the condition is of great significance when the frequency-response method, which is widely used in the linear control theory and practice, is employed to synthesize the simplest T-S fuzzy controller. Besides, this sufficient condition is featured by a graphical interpretation, which makes the condition straightforward to be used. Comparisons are drawn between the performance of the simplest T-S fuzzy controller and that of the linear compensator. Two numerical examples are presented to demonstrate how this sufficient condition can be applied to both stable and unstable plants.

双重子∑*△(ST=05/2)和∑*△(ST=31/2)态的结构

在推广的手征SU（3）夸克模型下,研究了带有一个奇异夸克的双重子态∑^＊△（ST=0 5/2）和∑^＊△（ST=3 1/2）的结构．结果表明,尽管手征SU（3）夸克模型和推广手征SU（3）夸克模型短程力的机制完全不同,但两种模型下给出的定性结果是一样的。即这两个双重子态都是束缚态。能量在∑^＊△道之下却在∧π△道之上．在推广手征SU（3）夸克模型下,∑^＊△（ST=3 1/2）态的结合能比∑^＊△（ST=0 5/2）态的结合能大．     

敦煌盆地五墩凹陷中间沟组一段物源体系

为明确敦煌盆地五墩凹陷中间沟组一段物源体系及展布,以岩矿与主量元素分析为基础,结合水动力条件、地震剖面反射特征和古地貌分析,研究砂体的发育程度、物源方向与搬运通道,探讨五墩凹陷侏罗系中间沟组不同井区的沉积物来源。研究结果表明：XC1井与D2井具有同源性,岩屑类型以变质岩岩屑为主,D1井物源表现出一定差异性,岩屑类型以岩浆岩岩屑为主,主量元素分析结果与岩屑类型分析结果相一致;XC1井和D2井主要为近源扇三角洲沉积,D1井主要为远源辫状河三角洲沉积;XC1井和D2井区主要接受南部三危山隆起物源区的沉积物供给,D1井区主要接受北部北山物源区的沉积物供给。重新落实的物源体系展布对于研究区砂体展布规律具有重要的指导意义。     

解析青春文学及青春文学出版现状

青春文学在内容方面充分体现了作为同龄人共有的生活场景、思维方式和性格特征,极易取得共鸣并获取情感上的宣泄。他们的写作体现了“80后”一代人的整体特征,个性张扬、叛逆不羁、惟我独尊等,作品中表现了很多同龄人共同的压抑感和迷茫感,在大量青少年读者中引起了强烈的共鸣。     

少数民族高校大学生思想政治教育存在问题的原因分析及对策

通过问卷调查,少数民族高校大学生思想政治教育存在国情了解不够,主动意识欠缺等问题,对这些问题进行分析,有三个方面的原因,学校方面存在思想政治教育宣传深度不够,缺乏有效监督机制和思政队伍不健全的原因;教师方面存在思政教育人人参与意识不强和扎实有效的教学方法不多原因;个人方面存在学习意识不强和个人职业规划不清晰的原因。通过原因分析,进而得出相应对策:一是学校创造思想政治教育条件;二是教师努力提升思政专业素养;三是大学生个人提高思想政治意识。
