| 1 | On the new results of global attractive set and positive invariant set of the Lorenz chaotic system and the applications to chaos control and synchronization显示文摘Constructing a family of generalized Lyapunov functions, a new method is proposed to obtain new global attractive set and positive invariant set of the Lorenz chaotic system. The method we proposed greatly simplifies the complex proofs of the two famous estimations presented by the Russian scholar Leonov. Our uniform formula can derive a series of the new estimations. Employing the idea of intersection in set theory, we extract a new Leonov formula-like estimation from the family of the estimations. With our method and the new estimation, one can confirm that there are no equilibrium, periodic solutions, almost periodic motions, wandering motions or other chaotic attractors outside the global attractive set. The Lorenz butterfly-like singular attractors are located in the global attractive set only. This result is applied to the chaos control and chaos synchronization. Some feedback control laws are obtained to guarantee that all the trajectories of the Lorenz systems track a periodic solution, or globally stabilize an unstable (or locally stable but not globally asymptotically stable) equilibrium. Further, some new global exponential chaos synchronization results are presented. Our new method and the new results are expected to be applied in real secure communication systems. | LIAO Xiaoxin 1, 2, 3 , FU Yuli 4 & XIE Shengli 4 1.

| 2 | Chinese Overseas investment Calls for Perfection of Overseas Investment Insurance显示文摘Overseas investment insurance is a non-profitable insur- ance provided by the government of a state for her enterprises which have invested in the developing countries or areas against political risks.Such a gov- ernmental guarantee system was first established in the United States in the middle of last century.Nowadays most developed countries and some of the developing countries have followed American practices and set up similar systems to encourage their enterprises to make investment in developing areas which are often regarded to be more easily to have political risks.In | Liu Yajun,associateprofessor,tutor of postgraduate,vice dean of the School of International Law of Northwest University of Political Science and Law.His main research orientation includes international trade law and international investment law. | 2008 | China's Foreign Trade2008,,8: | 22 |
| 3 | Event-related potentials in a Go/Nogo task of abnormal response inhibition in heroin addicts显示文摘Inhibitory control dysfunction is regarded as a core feature in addicts.The major objective of this study was to explore the time course of response inhibition in chronic heroin addicts and provide the neurophysiological evidence of their inhibitory control dysfunction.The amplitudes and latencies of ERP components were studied in fourteen heroin addicts(mean duration of heroin use being(13.54±5.71) years(Mean±SD),average abstinence being((4.67±6.44) months)) and fourteen matched healthy controls with a visual Go/Nogo task.Our results showed that heroin addicts demonstrated significantly larger Go-N2 amplitudes which results in a decreased N2 Go/Nogo effect,but no statistically significant differences were found between heroin addicts and controls in P3.The ERP data suggest that fronto-central areas of heroin addicts were impaired during the inhibition process(200-300 ms) and over-activated to targets.The impaired early process might reflect an abnormal conflict monitoring process in heroin addicts.These results consolidate the inhibitory control dysfunction hypothesis in chronic heroin users. | YANG Bo1,YANG SuYong2,ZHAO Lun3,YIN LiuHua1,LIU Xu1& AN ShaSha1 1 Laboratory of Psychology,School of Sociology,China University of Political Science and Law,Beijing 102249,China 2 National Key Laboratory of Cognitive Neurosciences and Learning,Beijing Normal University,Beijing 100875,China 3 Institute of Language,Xuzhou Normal University,Xuzhou 221116,China | 2009 | Science China(Life Sciences)2009,52,8: | 15 |
| 4 | Thermal Stability and Thermal Aging of Poly(vinyl chloride)/MgAl Layered Double Hydroxides Composites显示文摘MgAl-LDH(layered double hydroxides) were prepared with CO(NH_2)_2, NH_4 Cl and NH_3·H_2O by the coprecipitation method, respectively. Corresponding composite membranes were prepared by the coating method. LDHs were characterized by WAXS, CO_2-TPD and SEM. The morphology of the PVC/LDHs composite membranes were characterized by means of SEM. The thermal stability of the membranes was analyzed by air aging box and TGA-FTIR. The SEM results show that nano-particles can be compatible with poly(vinyl chloride)(PVC) matrix homogeneously by the stirring-ultrasound blend method with two steps. Furthermore, the air aging box results proved that MgAl-CO(NH_2)_2-LDH has the best effect on thermal stability of PVC. TGA-FTIR results show that MgAl-CO(NH_2)_2-LDH could adsorb more HCl that resulted from the degradation of PVC and improve the pyrolysis temperature of the first degradation stage by 15 K compared with PVC. | Hong-mei Zhang 张书华 Polite Stewart Chen-hui Zhu Wei-jun Liu Alexander Hexemer Eric Schaible 王成 | 2016 | Chinese Journal of Polymer Science2016,34,5: | 6 |
| 5 | Research on the Circulation Problems of Contractual Management Right of Rural Land显示文摘Based on the judicial explanation of the contractual management right of land, the thesis elaborates the definition of main body of contractual management right of rural land; right of possession, use right, usufruct of contractual management right of land; autonomy of production and operation; disposition of the products; expropriation and occupation compensation authority of contractual land respectively, in order to demonstrate the connotation of land contractual management. The thesis also analyzes perspicaciously the phenomenon of non-agricultural-use land and proclaiming phenomenon of contractual management right of land. We should establish normalized rural land property rights register system to perfect contractual management right of land. Proclaiming of agriculture land right also should adopt registration effectiveness so as to guarantee the legality of transference of agricultural land to non-agricultural land in terms of system. We should perfect rural land circulation in terms of normalizing land circulation laws and normalizing contractual farmers fees: in terms of the movable agricultural land right, we should further perfect the types and content of circulation and lessen non-legal form restrictions of circulation; in terms of contractual fees, we should normalize contractual fees of land in order to preclude the contradiction between the contractees and contractors arising from blank space of laws. | CHEN Han-bing Politics and Law Department of Zhoukou Normal University, Zhoukou 466001, China | 2010 | Asian Agricultural Research2010,2,12: | 4 |
| 6 | Analysis of the Ecological Migration Pattern in Ethnic Minority Areas——A Case Study of Ningxia Hui Autonomous Region显示文摘By taking Ningxia Hui Autonomous Region as an example,this paper analyzes the ecological migration pattern in ethnic minority areas.The basic patterns of development for poverty relief in Ningxia are in-situ migration and new area development pattern.The new area development pattern includes three types,namely small town development pattern around urban radiation districts,urban labor migration pattern,and large-scale ecological migration pattern.Finally,successful experience of ecological migration in Ningxia is summarized.First,scientific industrial planning shall be made on the basis of proper selection of ecological migration location in immigrant settlement regions.Second,scientific and comprehensive ecological migration policies should be formulated. | ZHANG Yun-yan School of Politics and Law,Ningxia University,Yinchuan 750021,China | 2011 | Asian Agricultural Research2011,3,8: | 4 |
| 7 | The Methods of Constructing the Legal Support System for the Returning-home Migrant Workers' Entrepreneurship——Based on the Perspective of Economic Law显示文摘Based on the overview of concept of returning-home migrant workers' entrepreneurship,the thesis has introduced the features of migrant workers' entrepreneurship,as against other types of entrepreneurship,as follows. Starting from a low base and multi-level perspective;conducting entrepreneurship in manifold industries,mainly in those labor-intensive enterprises;conspicuous mutual interaction and reversibility are embodied in the group characteristics;the strong driving force of returning-home migrant workers' entrepreneurship comes from their affection for hometown. The process of returning-home migrant workers' entrepreneurship can be divided into three stages,namely returning rush,investing rush,and entrepreneurship rush,on which we give the analysis respectively in terms of the continuous change of social mobility,transformation on the part of the main body of entrepreneurship,and the expansion of industry field concerning entrepreneurship. More over,we have discussed the methods of constructing the legal support system for the returning-home migrant workers' entrepreneurship. Firstly,it needs institutionalization,which is the basis of constructing the legal support system for the returning-home migrant workers' entrepreneurship;secondly,it needs definite guiding ideology as the premise of constructing the legal support system for the returning-home migrant workers' entrepreneurship;thirdly,it needs the precise orientation of target group as the key of constructing the legal support system for the returning-home migrant workers' entrepreneurship;finally,appropriate support methods are the pivot of constructing the legal support system for the returning-home migrant workers' entrepreneurship. | OU Rong-rong,GONG Xuan-jie Southwest University of Political Science and Law,Chongqing 401120,China | 2010 | Asian Agricultural Research2010,2,4: | 3 |
