Acta Mathematicae Applicatae Sinica 2004年第3期20卷 457-476页

This paper uses the geometric singular perturbation theory to investigate dynamical behaviors and singularities in a fundamental power system presented in a single-machine infinite-bus formulation. The power system can be approximated by two simplified systems S and F, which correspond respectively to slow and fast subsystems. The singularities, including Hopf bifurcation (HB), saddle-node bifurcation (SNB) and singularity induced bifurcation (SIB), are characterized. We show that SNB occurs at P Tc = 3.4382, SIB at P T0 = 2.8653 and HB at P Th = 2.802 for the singular perturbation system. It means that the power system will collapse near SIB which precedes SNB and that the power system will oscillate near HB which precedes SIB. In other words, the power system will lose its stability by means of oscillation near the HB which precedes SIB and SNB as P T is increasing to a critical value. The boundary of the stability region of the system can be described approximately by a combination of boundaries of the stability regions of the fast subsystem and slow subsystem.

气相爆轰合成是一种新型的碳纳米材料制备方法,相对于其他碳纳米材料制备方法而言具有反应速度快、产物种类多、产量大、纯度高、操作简单和经济性高等优点,有利于促进碳纳米材料的工业化生产。为深入阐明气相爆轰法合成碳纳米材料的研究与发展状况,介绍了气相爆轰法合成所需仪器设备、实验流程、理论计算以及产物的表征方法等,整理归纳了气相爆轰法合成碳包覆纳米金属粒子、碳纳米球、碳纳米管、碳点和碳纳米胶囊等技术与方法,分析了合成产物的形貌、结构及性能特征,展望了气相爆轰下各种新型碳纳米材料的应用潜力与技术发展趋势,以期为合理设计、针对性优化、规模化合成纳米材料奠定理论基础。研究表明:爆轰合成应结合宏观的爆轰理论和微细观的粒子生长。当前借助爆轰波发动机与爆轰胞格结构研究热点,使宏观爆轰胞格与纳米材料微观合成过程构成联系是重点研究方向。然而,在研究爆轰合成粒子的生长机理时,聚集在微细尺度上的纳米粒子生长仍然也是一种跨尺度问题,有必要引入分子动力学和格子波尔兹曼计算方法加以解决。

习近平法治思想中的公平正义观,是中国共产党安邦治国的重要价值取向。其来源于马克思主义经典作家的公平正义思想,内蕴着中华优秀传统文化关于国家治理的智慧,继承了中国共产党对公平正义理想的不懈追求。习近平法治思想中公平正义观的科学内涵可以从“权利公平、机会公平、规则公平”这三个方面加以诠释。践行习近平法治思想中的公平正义观,要完善以宪法为统帅的中国特色社会主义法律体系,维护社会公平正义;深化司法体制综合配套改革,全面落实司法责任制;紧紧抓住经济建设这个中心,为保障社会公平正义奠定更加坚实的物质基础;推动构建人类命运共同体,坚定维护国际公平正义。

作者： chuah Tse Sengt Noor Hafiul Bin Wahad Liew hong Jung Department of Agro-technology Faculty of Agro-technology and Food Science University of Malaysia Terengganu 20130 KualaTerengganu Terengganu Malaysia Department of Fisheries Science and Aquaculture Faculty of Fisheries and Aqua Industry University of Malaysia TerengganuKuala Terengganu Terengganu 20130 Malaysia Institute of Tropical Aquaculture University of Malaysia Terengganu 20130 Kuala Terengganu Terengganu Malaysia

This study was conducted to screen the commercial herbicides for algae control in the aquarium. Three herbicides of ametryn, atrazine and metribuzine were tested at concentrations ranging from 0.625 to 10.00 ppm. It is found that ametryn was the most effective herbicide that inhibited algal growth. Ametryn concentration that caused 50% inhibition on algae growth after exposure for 21 days was 0.335 ppm. Survival rate of oruamental fish, Harlequin rasbora （Trigonostigma heteromorpha） and growth rate of aquatic plant （Elodea canadensis） exposed to 10 ppm ametryn were compared with those exposed to algaecide. The result showed that there was no significant difference in survival rate of Harlequin rasbora when exposed to ametryn, algaecide and dechlorinized tap water （control）. However, growth rate of E. canadensis was lower after exposure of ametryn compared to those exposed to algaecide and tap water. These results suggest that ametryn has potential to be used as an algal inhibitor in aquarium.
