Research on Benefit Mechanism of Local Government Co-opetition (Education Papers posted on June 10th, 2015 )
Since the reforms in decentralization and marketization in 1980s, the Chinese government has divided its powers to the local divisions stage by stage and has enabled them more and more independent roles of regional interest entities. On dealing with certain issues, the rational actions of some local government may turn into the irrational ones in terms of macroeconomics. In order to develop its regional economy, the local power competes fiercely against its counterparts. Actually speaking, they pay high and gain much less than their maximal interests in the vicious competition. Meantime, this competition will be intensified further along with the elevation of the status of the regional economy during the processes of reform and opening, world science and technology innovation, and globalization. In particular, China’s entry into WTO has placed the responsibilities on the local governments of not only developing themselves, but reinforcing the competitiveness of the state. It is known that the key point to advance the country’s overall strength is to integrate its inside parts. Likewise, the essence of realizing the regional competitiveness is the regionally internal integration. Accordingly, it can regulate the competition among local governments with the guidance for them to forward towardsin accordance with their separate interests, which will boost the constant development of both regional and overall economy.The paper assumes that the local governmental relations are inevitable to trend toward . It attempts to construct a model to construe the reasons of regionally governmental competitions from the angle of the interest relations. After the analysis of impact of interest changes of local governments on their co-opetitions, it proposes corresponding mechanisms to speed up the co-opetitions, i.e. interest regulation mechanism, interest partaking mechanism and interest competition mechanism.
Planning Method Research of Remote Sensing Data Acquisition Resources with Emergencies (Education Papers posted on June 10th, 2015 )
With the development of space remote sensing data acquisition technology, it gets more and more attention of government that using space Data Acquisition Resources (DARs) to observe and evaluate the status of natural disasters, public emergencies ands. Acquiring remote sensing data in good time can provide information to make a decision in the emergency environment efficiently with the purpose of reducing the harm of natural disasters and public emergencies to the minimum.Our country has satellites of disasters inspecting, weather satellites and other various types of earth observe satellites, but currently we have no en effective mechanism for the unified planning and scheduling of all DARs. So, in this paper, we design a framework of this DARs planning and scheduling problem, and according to this framework, we carry out an expert system for tasks allocation and DARs filtrating, also we provided two kinds programming arithmetic. The main research content of this paper and innovation points are shown as follows:1. On the base of research and analysis of space DARs planning and scheduling, we program two kinds of model tightly coupled and loosely coupled for DARs planning and scheduling based on the characteristic that there are variety of DARs and these DARs are supervised by different departments.2. According to the framework, in the data pre-processing module, we design an expert system based on rules for task allocation and resource filtering by calling the CLIPS expert inference engine.3. For the DARs planning of emergency, we design and to select the observations of all usable DARs. And experiment shows that the is appropriate for less scale problem and is more appropriate for larger scale problem.4. With urgent request of remote sensing data in true-life of our country, we design a planning and scheduling system of DARs to emergency. And this system can works quickly for different problem scales.
The Reliability of Fund Maintenance System with Priority (Education Papers posted on June 10th, 2015 )
Repairable system is a system of great importance discussed in reliability theory. In the past, scholars around the world tended to base the study of repairable system model on the hypothesis of continuous time. However, there are few people in China who would give priority to certain parts in the system when doing maintenance and repairing work to maintain a high-performance of the whole system, which is due to the complexity of the problem.The truth is that in real life, when we regularly examine and repair the system, statistic values such as service life and repair time should be taken as random sequence of non-negative integral value instead of continuous random variable. It is necessary to study the characteristics of discrete repairable system, which could be an example inapplication, and has a wide application prospect for network topological structure in the field.Based on existing research results, the paper has studied several aspects of the reliability of fund Maintenance System Consists of Two Types of Components with as follows:In the chapter 2, the paper discusses three case of the reliability of Maintenance System Consists of Two Types of Components with priority: Firstly, In the condition of absolutely reliable switch, we study the system which consists of two types of components with priority, and a maintained distributions of the working time and maintaining time are general time distributions. Secondly, In the condition of unreliable switch, we study the cold-fund system which consists of two types of components with priority, and a maintained distributions of the working time and maintaining time are general time distributions. Finally, In the condition of absolutely reliable switch, we study the cold-fund system which consists of two types of components with priority, and a maintained distributions of the working time and maintaining time are geometric distributions. Then we deduce some reliability indicators of these models by Markov process, Generating Function, LS-transformation, L-transformation.In the chapter 3, discussing two case of the reliability of warm-fund Maintenance System Consists of Two Types of Components with priority: Firstly, using the theory of classical reliability, in the condition of absolutely reliable switch. we set a reliability model about system on warm-fund. This warm-fund consists of two types of components with priority and a maintained device. We also deduce some reliability indicator of this model by principles and methods, LS-transformation. Secondly, In the condition of absolutely reliable switch, we study the warm-fund system which consists of two types of components with priority, and a maintained distributions of the working time and maintaining time are geometric distributions. We also deduce some reliability indicators of this model by Markov process, Generating Function, LS-transformation.In the chapter 4, the paper discusses Fuzzy Reliability of Maintenance System of Two Components with , using the theory of classical reliability and fuzzy reliability, in the condition of absolutely reliable switch; we set a fuzzy reliability model about system on warm-fund. This warm-fund consists of two types of components with priority and a maintained device. We also deduce some fuzzy reliability indicator of this model by principles and methods, LS-transformation.
Crystal Structures and Luminescence of Complexes of Bis-[(3,5-dimethyl)-4-pyrazole]methane: Toward the Effect of Second Ligands (Education Papers posted on June 10th, 2015 )
Spaced-biligands are a family of polydentate, middle-hard-base donors that can form stable coordination compounds with most of transition metal ions. Because of their labile, non-chelating and linking coordination modes, the ligands can be used as linkage for construction of structurally intriguing s, thus they have attracted extensive attention of current coordination chemistry. For that reason, we prepared a ligand, namely, bis-[(3,5-dimethyl)-4- ]methane (DMPM) and, using it as primary ligand, along with different second ligand, synthesized 11 s, which were structurally identified by single crystal and powder X-ray diffractions, and some of which were photophysically investigated. Herein, we report the structures and properties of these products sorted according to the types of second ligands.Chapter 1 introduces briefly the progress of coordination chemistry research and the factors affecting the construction of complexes. Subsequently a survey on the on-going advance of DMPM coordination chemistry is made and finally the aim of the present work is elucidated.In chapter 2, we reports three new complexes, synthesized from reactions of DMPM, as main ligand, and linking anions (I-, SCN-,SO42-), as second ligands, with metal salts. Among the products, [Cd(I)2(DMPM)] (1) is a zero-dimensional (0-D) dinuclear complex, while [Cd(SCN)2(DMPM)2]n (2) and [Cu(SO4)(DMPM)]n (3) are 1-D. In all three compounds, the first ligands act as angular linkers. In crystal packing, all three compounds give the high-dimensional supramolecular systems unified via hydrogen bonds.Chapter 3 includes four Cd2+ complexes with DMPM as primary ligand and aromatic polycarboxylic acids (phthalic (H2PA), terephthalic (H2TPA), isophthalic (H2IPA), and benzene-1,3,5-tricarboxylic (H3BTA)) as axiliary ligands. X-Ray structural analysis reveals that [Cd(BA)(Cl)(DMPM)2]n (4) is uniquely assembled in 1-D because the H2PA losses one of two carboxylates and so acts as a terminal ligand, stopping the extension of along its propagation. For the reason, the complex, in virtue of the linking of DMPM, structures as a chain running along a direction. Complexes, [Cd(TPA)(DMPM)]n(5), [Cd(IPA)(DMPM)]n(6), [Cd(HBTA)(DMPM)]n(7), are 2-D. Particularly, the first ligands in 5 are cis-configured, incorporating into TPAs, give a plain three-connection (6,3) topology. Instead, those in 6 are configured as either cis or trans, of which the cis, combining to Cd2+ ions, furnishes the zigzag chains and the trans, combining to Cd2+ ions, furnishes the helices. With incorporation of Cd2+ into the diversely configured DMPMs and angular IPAs, the ternary polymer gives a binodal (52.62.72)(53.63) topologized net. Indicatively, the first ligands in 7 are all trans-configured, to work together with HBTA, rendering a (4, 4) network. Luminescence spectra of three 2-D complexes suggest that the energies of DMPM-based emissions of them are analogous, but not the widths. A suggestion of the observation is that the photoresponse of DMPM is subject to its coordination manner. What is more, the thermal analysis reveals that the complexes are decomposed in the same way, but different in the desertion temperature of DMPM, based on which we can conclude that the second ligands affect not only the coordination mode of DMPM and assembly of coordination polymers, but also their luminosity and thermal property.In chapter 4, four complexes with DMPM as first ligand and pyridine dicarboxylic acids (2,5-pyridine dicarboxylic acid (2,5-PDC), 2,6- pyridine dicarboxylic acid (2,6-PDC)) as second ligands, are demonstrated, of which the [Cd(3-PDC)2(DMPM)]n (8) is 2-D and can be reduced into a (44, 62) topological network, therein the 2,5-PDC appears as 3-picolinic acid for the decarboxylation of 2-position and gives the double-stranded helix, in combination to Cd2+. Instead, the [Zn(2,5-PDC)(DMPM)]n (9) constructs as a 1-D triple strand. In another comparison, the Cl-involving [Cd2(2,6-PDC)(μ2-Cl)(Cl)(DMPM)·H2O]n (10) configures as a 2-D network presenting a (42.62)2(42.62.82) topology, in contrast to the I-involving [Cd2(2,6-PDC)I2(DMPM)]n (11), as a grid-like network. Fluorescence of 8 and 10 indicates that the photoresponses of two compounds are comparable, meaning that the position-isomeric second ligands not significantly affect the bulk photobehavior of the complexes.

Design and synthesis of amphiphilic copolymer with complex architect… (Education Papers posted on June 10th, 2015 )
Design and synthesis ofcopolymer with complex are always pursued by polymer chemists in past decades. Thanks to the development of living polymerization, combining the living radical polymerization with ionic polymerization, some linear and nonlinear （such as comb-like, star, dendritic, hyperbranch） copolymers are synthesized.Amphiphilic and functional ABC s have attracted more interests in the last decades for their widely application in self-assembly field. Among their different components poly（ethylene oxide）（PEO） was the most familiar, due to its outstanding properties such as biocompatibility, crystallizability and well dissolvability in water and most organic solvent. That’s why PEO was always considered as one of the blocks when scientists design new ABC s.On the other hand, for the multiblock copolymers, the synthesis is solely confined in polycondesation of prepolymers. It is still a challenge to explore a simple and effective way to synthesize these copolymers via living polymerization. Herein, we have synthesized different ABC triblock copolymers by the combination of different living polymerization, and study the effect on the properties of triblock copolymers with PEO as different position, and this was rarely investigated. In this paper, the triblock copolymers mPEO-b-PCL-b-PS and PS-b-PEO-b-PCL with PEO as different position were successfully synthesized by the combination of living anionic polymerization, coordination-insertion ring-opening polymerization, atom transfer radical polymerization, and nitroxide-mediated radical polymerization. The main results have been obtained as follows:1. The ABC amphiphilic triblock copolymers mPEO-b-PCL-b-PS was designed and synthesized. The EO was polymerized by living anionic polymerization using di（ethylene glycol） potassium as initiator, theα-methoxy poly（ethylene oxide） （mPEO） was obtained. The mPEO was served as macroinitiator to initiate the polymerization ofε-caprolactone by coordination-insertion ring-opening polymer- ization using stannous octoate （Sn（Oct）2） as catalyst, and the diblock copolymers were obtained. Then the macroinitiator mPEO-b-PCL-Br for atom-transfer radical polymerization was obtained by 2-Bromoisobutyryl bromide reacting with the hydroxyl at the end of resultant diblock mPEO-b-PCL. Finally, the mPEO-b-PCL-Br was served to initiate the polymerization of styrene （St） by atom-transfer radical polymerization （ATRP） in the present of copper bromide and N,N,N’,N”,N”-Pentamethyldiethylenetriamine（PMDETA）, and the desired triblock copolymers mPEO-b-PCL-b-PS were obtained. The investigation of kinetics of the polymerization of styrene confirmed that the polymerization was under control. The desired triblock copolymer and its intermediates were characterized.2. The ABC amphiphilic triblock copolymers PS-b-PEO-b-PCL was designed and synthesized. Firstly, the EO was polymerized by living anionic polymerization using 4-hydroxyl-2,2,6,6-tetramethylpiperidinyl-1 -oxy and diphenylmethyl-potassium （DPMK） as initiator, and the TEMPO-PEO with 2,2,6,6-tetramethylpiperidinyl-1-oxy（TEMPO） and hydroxyl end group was obtained. The TEMPO radical in TEMPO-PEO acted as a radical trapper to mediate the polymerization of styrene （St） by nitroxide-mediated radical polymerization （NMP） using benzoyl peroxide （BPO） as initiator, and the diblock copolymers were obtained. Finally, The PS-b-PEO was served as macroinitiator to initiate the polymerization ofε-caprolactone by coordination-insertion ring-opening polymerization using stannous octoate （Sn（Oct）2） as catalyst, and the desired triblock copolymers PS-b-PEO-b-PCL were obtained. The desired triblock copolymer and its intermediates were characterized.The position of each block of multiblock copolymers have effect for properties of multiblock copolymers. It was confirmed that the PEO block position have effect on Tg and Tm of each block of ABC amphiphilic triblock copolymers mPEO-b-PCL-b-PS and PS-b-PEO-b-PCL by DSC.
