Let {X_n;n≥1}be a sequence of m-dependent Banach space valued random variables with mean zeros and finite variances, by using the weak convergence theorem of m-dependent Banach space valued random variables, we studied the precise asymptotics of the complete convergence and the law of the iterated logarithm for the sequence {X_n;n≥1}. We extended the results of the precise asymptotics of the complete convergence and the law of the iterated logarithm for real valued i.i.d.random variables.

The generalized gradient of a kind of set-valued mappings is introduced into ordered Banach spaces and under certain conditions its existence is proved via the separation theorem. The optimality conditions of super-efficient solution of set-valued optimization problems are presented in the sense of generalized gradient.

Based on the gradient model that the properties of them obey a power law with respect to the thickness of piezoelectric functionally gradient materials, a modified factor representing the error between design and implement is introduced. A modified classical laminate theory involving piezoelectric coupling terms, by which the plate is divided into a certain number of sufficiently thin layers, is employed. Thus the material properties in any layer can approximately be regarded as uniform. An analytical study for a simply supported piezoelectric functionally gradient rectangular plate subjected to an e lectric field is only presented. The influences of microstructural parameters such as the component distribution factor, the thickness of each layer and the number of layer, on material performance are discussed. It has been found that the effects are significant in a certain range, and beyond the range the effects are neglectful. Those results can provide a certain basis for the optimization design of piezoelectric functionally gradient materials.

According to the fact that E₁^s,t,* of May spectral sequence is converged to E_A^s,t(Z_p,Z_p) and EE₂^s,t of Adams spectral sequence is converged to stable homotopy groups of sphere π_t-s(S)_p combined with the exact sequence of Ext group induced from the confibration of spectrum. A nonzero element g₀(b₁)⁴ of stable homotopy groups of V(2) is found, and it is a permanent cycle in Adams spectral sequence. With the help of Yonedaproducts, a nonzero element g₀(b₁)⁴γ_s of stable homotopy groups of sphere is obtained.

A practical manual neural network model was designed to make the location of target and predication. We used error backward direction propagation calculation method and established three-layer neural network to solve the problems of serious overlap of spectral peaks and big noise in the spectrum analysis. When the quantity of samples to be located is significant, We employed manual neural network method to analyze and discuss the corn’s protein content and nearinfrared spectrum. By analyzing the experimental result it is concluded that manual neural network method is superior to linear regression method and partial leastsquares method.

The ATLAS-EBNF grammar not only introduces more operators than common EBNF, but defines precedence between operators. Owing to its particularity, we can not design a parser for ATLAS-EBNF directly, so a grammar transformation is needed. A transformation technique was proposed based on super grammar and the proof of its correctness was given. The transformation technique was applied and verified in our project for the implement of ATLAS.

Finally, the experiment results show that this technique presents superior results than those obtained from other methods.

We investigated the chaotic/hyperchaotic synchronization of two erbium-doped fiber dual-ring lasers using delay injection-feedback. The numerical simulation shows that the two same erbium-doped fiber dual-ring lasers can easily achieve synchronization even though they are chaotic or hyperchaotic only if the delay time and intension of feedback are suitable, even if two lasers are not completely uniform, they also achieve chaotic/hyperchaotic synchronization only if the intension of feedback is suitably added. At the same time, the two lasers show delay synchronization for different delay time, this delay synchronization just account for the delay effect in telecommunication and is available for chaotic secure communication.

The assemblies of the C₆₀ mixed film and the behenic acid (BA) film were made successfully by means of Langmuir-Blodgett (LB) technique with BA, arachic acid (AA), stearic acid (SA) and octadecanyl amine (OA) as the assistant material, and the reorganization of the LB films was directly observed by liquid atomic force microscopy (AFM). The AFM data show that the C₆₀ mixed film and the BA film were all reorganized in water with the uniform size of C₆₀ aggregates, and the weaker reorganization was observed for the former. It is considered that the Cd²⁺ in water decreased the interaction resulted in the reorganization of alkyl chains between headgroups and the mica substrate. Owing to the reaction of the acid and alkali, the C₆₀ mixed film got weaker reorganization in water compared with the cadmium behenic films.

The author adopted Monte Carlo method to simulate the linear polymer chain lattice model, and made a research on the variation of polymer dynamic behavior with the interaction energy changing among the system components. The author discussed the changes of physical parameters that describe chain dynamics g_cm(t), g_m(t), g_e(t) and g_r(t) with the increase of the interaction energy ε_PS between solvent molecules and polymer chain segment molecules, and interaction energy ε_PP among polymer chain segment molecules. The results indicate that ε_PP has less impact on polymer dynamic behavior than ε_PS, but the tangling character of the system is mainly affected by the chain length of the system， does not depend on the change of ε_PS and ε_PP absolutely.

The resulting samples were examined by means of transmission electron microscopy (TEM), FT-IR spectroscopy and X-ray powder diffraction (XRD).

The distribution and accumulation of Cu,Zn,Cd and Pb in multi-phase media(water phase, surficial sediments, surface coatings and suspended particulates) in the Nanhu Lake were investigated. The results show that the content of Zn is the highest among the four metals in all the phases, but the accumulation capacity of Cd is better than that of Zn although the content of Cd is the least; among all the phases, the accumulation capacities of the heavy metals of the suspended particulates and the surface coatings are much better than those of the surficial sediments, and a-point-source pollution is a common characteristic of these four heavy metals. Then the correlation analyses between the metals were studied by means of SPSS statistical analysis with SPSS for Wi ndows (V6.0), and the results indicate that the trends of correlation between the metals of the surficial sediments, suspended particulates and surface coatings are more or less different from each other, and Cd content correlates better with Fe content and Pb correlates better with Mn content, implying that in the aquatic environment, Fe oxides have more effect on the chemical behavior of Cd and Mn oxides have more effect on the chemical behavior of Pb from the view of statistical analyses.
