Preparation of LiNi_(1-y)CoyO_2 in certain oxygen pressure

The LiNi_(1-y)Co_yO_2 as cathode material of lithium ion battery was prepared by solid reaction at high temperature and oxygen pressure. The influences of the prepared conditions on electrochemical properties of products were discussed which include the pressure of oxygen, synthesis time and temperature as well as the molar ratio of the raw materials. The optimal synthetic conditions are as follows: reactive time is 8h and 10h; oxygen pressure is 0.20MPa;reactive temperature is 800℃;and molar ratio of the reactants is Li∶Ni∶Co =1.2∶0.9∶0.1. LiNi_(0.9)Co_(0.1)O)2 was synthesized with the perfect crystal structure and the good electrochemical properties. Its discharged capacity is up to 189.4mAh/g. The results of X-ray diffraction and SEM analysis reveal that the product presents a layered structure of LiNiO_2. The increase of the oxygen pressure during the reactive processes has important effects on the structure and electrochemical properties of the product.
Solidification of Al alloys under electromagnetic field

New theories and technology in the electromagnetic field were put forward about DC casting of Al alloys, including the fundamental research works, i.e, effects of the electromagnetic field on solidus and liquidus, macrosegregation of the main alloying elements, microstructures, content of alloying elements in grains and grain size after solidification under electromagnetic field, and also including a new process-DC casting under low frequency electromagnetic field(LFEMC), which can refine microstructure, eliminate macrosegregation, increase the content of alloying elements within grains, decrease the residual stress, avoid cracks and improve surface quality, and another new process-DC casting under low frequency electromagnetic vibration(LFEVC), which is a high effective method for grain refining.
Effect of microstructure on specific capacitance of AA3003 aluminum alloy foils

By means of OM, EDS, SEM and TEM, the effect of microstructures of AA3003 aluminum alloy foils on specific capacitance was investigated . The results show that the specific capacitance of the cathode aluminum foils depends on the microstructures of the foils, including intermetallic compound (Mn,Fe)Al_6 and Al matrix, tangled dislocations in the regions adjacent to the intermetallic particles, and smaller and dispersed particles. Because the dislocation interaction with larger particles gives rise to high local lattice curvature in the matrix, which can be preferentially dissolved when etched, which results in serious remnant metal powders on the foil surface. Solid solution at 630 ℃, quenching in water and aging at 60 ℃ may increase the number of the second phase particles, and reduce the large particles, so that the capacitance of the cathode foils becomes higher and almost no powders remain on the surface of the foil. By means of aging after quenching, the precipitated particles and etch-pit density in the foil increase obviously, therefore the favourable microstructures can be produced to improve the specific capacitance of the foils.
Analysis of solar radiation variations over Nanjing region in recent 40 years

The data utilized in this analysis consisted of extraterrestrial radiation, global radiation, diffuse radiation, direct radiation, total cloud cover and relative sunshine. The annual variations and trend were analyzed for monthly mean daily total global, direct, and diffuse radiation on a horizontal surface and for the relations between global, direct, diffuse radiation and relative sunshine, total cloud cover. The climatological calculation equations of global and direct radiation are put forward. The results show that global and direct radiations are characterized by decrease and diffuse radiation by increase. The main causes are due to the increase of concentration of suspended particles and atmospheric turbidities rather than cloud cover variations.
Landuse/landcover changes in Zhangye oasis of Hexi Corridor

Taking two false color composite Landsat 5 TM (Thematic Mapper) images of band 4,3,2 taken in 1995 and 2000 as data resources, this paper carried out study on LUCC of Zhangye oasis in recent five years by interpretation according to land resources classification system of 1:100,000 Resources and Environmental Database of the Chinese Academy of Sciences. The results show that great changes have taken place in landuse/landcover in Zhangye oasis since 1995: (1) Changes of landuse structure show that cropland and land for urban construction and built-up area increased, on the contrary, water area and grassland decreased. These changes reflect the deterioration of eco-environment and the acceleration of urbanization, and also indicate the problems existing in the arrangement of water and land resources between the upper and lower reaches of the Heihe River. (2) Regional differences of landuse/landcover are evident, characterized by following aspects: in Sunan County located in Qilian Mountain area, unused land and grassland decreased, but cropland and land for urban construction and built-up area increased. In Minle and Shandan counties located in foothills, unused land, water area and cropland decreased, but grassland and land for urban construction and built-up area increased. In Zhangye City, Linze County and Gaotai County located in plain area of the middle reaches of the Heihe River, unused land, water area and grassland decreased, while woodland, cropland and land for urban construction and built-up area increased.

Electrokinetics removal of lead from lead-contaminated red soils

Ex-situ electroremediation tests were conducted on the lead-contaminated red soils to find out the optimum condition for the most efficient removal of lead pollution from the red soil, and to examine the relation of the pH of the soil with the electroremediation efficiency. The results show that the electroremediation technology is efficient to remedy Pb contaminated red soils, and the removal efficiency can be enhanced by controlling pH value in the cathode reservoir with HNO3. The average removal efficiency of Pb is enhanced from 24.5% to 79.5%, and the energy consumption reaches 285kW·h per m~3 red soil.

Composition and flux of nutrients transport to the Changjiang Estuary

Based on the results of water sample measurements of nutrient concentrations at the Datong Station of the Changjiang River from 1998 to 1999, combined with historical data of water quality, seasonal variations of nutrient concentrations and nutrient transports are discussed.The following results have been obtained: (1) the fluxes of the nitrate nitrogen, ammonium nitrogen and nitrite nitrogen increased by time-series from 1962 to 1990, even if runoff volume had a little variation; (2) the concentrations and fluxes of the dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphorus (DIP) increased notably with time, but those of the dissolved silicon (DSI) decreased pronouncedly; and (3) the concentrations and fluxes changed synchronously with time between the Datong Station and the Changjiang Estuary.
Deterministic VLSI Block Placement Algorithm Using Less Flexibility First Principle

In this paper, a simple while effective deterministic algorithm for solving the VLSI block placement problem is proposed considering the packing area and interconnect wiring simultaneously. The algorithm is based on a principle inspired by observations of ancient professionals in solving their similar problems. Using the so-called Less Flexibility First principle, it is tried to pack blocks with the least packing flexibility on its shape and interconnect requirement to the empty space with the least packing flexibility in a greedy manner. Experimental results demonstrate that the algorithm, though simple, is quite effective in solving the problem. The same philosophy could also be used in designing efficient heuristics for other hard problems, such as placement with preplaced modules, placement with L/T shape modules, etc.

Selective extraction of zinc from sulfate leach solution of zinc ore

Selective extraction of zinc from sulfate leach solution of zinc ore was studied. D2EHPA dissolved in 260＃kerosene was used as extractant. The pH-extraction isotherms show the extraction order of D2EHPA for metals is Fe~(3+)＞Zn~(2+)＞Ca~(2+)＞Al~(3+)＞Mn~(2+)＞Cu~(2+)＞Cd~(2+)＞Co~(2+)＞Ni~(2+)＞Mg~(2+)(pH0.5). This confirms that Fe3+ is preferentially extracted before the extraction of zinc. Extraction experiments were carried out with varying the extractant content, equilibration time, aqueous pH and phase ratio, and the solvent extraction of zinc with sodium salt of D2EHPA were also investigated. Some impurity co-extracted into the zinc loaded organic phase was efficiently removed by scrub, and the Fe3+ was hardly stripped from organic phase by sulfuric acid, hence zinc was separated from Fe~(3+) by selective stripping. A pregnant zinc sulfate solution with low contaminants was obtained by selective solvent extraction.
Simulation of aging process of lead frame copper alloy by an artificial neural network

The aging hardening process makes it possible to get higher hardness and electrical conductivity of lead frame copper alloy. The process has only been studied empirically by trial-and-error method so far. The use of a supervised artificial neural network(ANN) was proposed to model the non-linear relationship between parameters of aging process with respect to hardness and conductivity properties of Cu-Cr-Zr alloy. The improved model was developed by the Levenberg-Marquardt training algorithm. A basic repository on the domain knowledge of aging process was established via sufficient data mining by the network. The results show that the ANN system is effective and successful for predicting and analyzing the properties of Cu-Cr-Zr alloy.
Magnetic force microscope study on anisotropic NdFeB permanent magnets

NdFeB permanent magnets prepared by powder metallurgy were investigated using magnetic force microscopy (MFM). The excellent MFM images of sample along the surfaces parallel and perpendicular to the alignment axis were collected respectively. The results show the necessity of annealing procedure in the preparation of the samples to remove the polishing surface stress and to illustrate the real magnetic domain structure, so that the much information about both the magnetic structure and the topographic microstructure is obtained. The hard MFM tip is verified to be effective for this material especially for the sample with the examined surface parallel to alignment axis. By analyzing these well-captured magnetic force images, magnetic domains and alignment degree as well as the topographic information such as grain size and the nonmagnetic phases at the grain boundaries were demonstrated.
Influence of Arctic Oscillation on winter climate over China

In this study the relationship between the Arctic Oscillation (AO) and climate in China in boreal winter are investigated. Correlation analysis for the last 41 years shows that the winter temperature and precipitation in China change in phase with AO. High positive correlation (> 0.4) between temperature and AO appears in the northern China. High correlation coefficients between precipitation and AO cover the southern China (close to the South China Sea) and the central China (between 30°-40°N and east of ～ 100°E), with the values varying between +0.3 and +0.4. It is found that during the past several decades the precipitation was strongly affected by AO, but for the temperature the Siberian High plays a more important role. At the interdecadal time scale the AO has significant influence on both temperature and precipitation. Multivariate regression analysis demonstrates that AO and the Siberian High related variance in temperature and precipitation is 35% and 11% respectively. For precipitation, however the portion is rather low, implying that some other factors may be responsible for the changes in precipitation, in addition to AO and the Siberian High.
Ions Bombardment in Thin Films and Surface Processing

Ions bombardment is very important in thin films and surface processing. The ion energy and ion flux are two important parameters in ion bombardment. The ion current density mainly dependent on the plasma density gives the number of energetic ions bombarding the substrate. The self-bias voltage in plasma sheath accelerates plasma ions towards the substrate. RF discharge can increase plasma density and RF bias can also provide the insulator substrate with a plasma sheath. In order to choose and control ion energy, ion density, the angle of incidence, and ion species, ion beam sources are used. New types of electrodeless ion sources (RF, MW, ECR-MW) have been introduced in detail. In the last, the effects of ion bombardment on thin films and surface processing are presented.
Structure and micro-tribological properties of PTFE/Al_2O_3 micro-assembling film

In order to improve the wear resistance of elastic metallic-plastic thrust bearing pad, micro-assembling PTFE/Al_2O_3 multi-layer film was developed by alternating radio frequency(RF) magnetron sputtering PTFE and Al_2O_3 targets. For enhancing the adhesion of the interfaces between PTFE and Al_2O_3 film, N~+ implantation was employed. The structure, mechanical and micro-tribological properties were studied by XPS, X-ray photoelectron spectrometer and atomic force and friction force microscope (AFM/FFM). The results show that the multi-layer consists of Al_2O_3 component and crystalline PTFE. The hardness of the multi-layer modified by ion implantation is less than that of Al_2O_3, but its toughness is greatly improved. The friction coefficient of PTFE/ Al_2O_3 multi-layer modified by ion implantation is much lower than that of Al_2O_3 film, and its resistance to wear is much greater than that of PTFE film. Therefore the wear resistance of elastic metallic-plastic thrust bearing pad is greatly improved.
Forest landscape patterns dynamics of Yihe-Luohe river basin

Based on the information from forest resources distribution maps of Luoning County of 1983 and 1999, six indices were used to analyze spatial patterns and dynamics of forest landscapes of the typical region in the middle of the Yihe-Luohe river basin. These indices include patch number, mean patch area, fragment index, patch extension index, etc. The results showed that: (1) There was a rapid increase in the number of patch and total area from 1983 to 1999 in the study area. The fragment degree became very high. (2) The area of all the forest patch types had witnessed great changes. The fractal degree of each forest patch type became big from 1983 to 1999. The mean extension index of Robinia pseudoacacia forest, non-forest, shrub forest, sparse forest, and Quercus species forest increased rapidly, but that of economic forest became zero. The fractal dimension each showed that forest coverage has been promoted. (3) The changes of landscape patterns were different in different geomorphic regions. From 1983 to 1999 the vegetation cover area, the gross number and the density of patch, diversity and evenness of landscape were all reduced greatly in gullies and ravines, but the maximum area and the mean area of patch types were increased. In hilly region, both the forest cover area and the number of patch increased from 1983 to 1999, but the mean area of patch was reduced greatly. In mountain region, even though the area under forest canopy reduced from 1983 to 1999, the patch number was increased greatly, the mean area of all patch types was reduced, the extension index, diversity index and evenness index of landscape were all increased. Furthermore, because of different types of land use, human activity and terrain, the vegetation changes on northern and southern mountain slopes  were different. According to these analyses, the main driving forces, such as the policies of management, market economy, influence of human activities etc. are brought out.

Strengthening technology and mechanism for semi-solid die casting of aluminum alloy

Combined with theoretical evaluation, an optimized strengthening process for the semi-solid die castings of A356 aluminum alloy was obtained by studying the mechanical properties of castings solution treated and aged under different conditions in detail, then, the semi-solid die castings and liquid die castings were heat treated with the optimized process. The results show that the mechanical properties of semi-solid die castings of aluminum alloy are superior to those of the liquid die castings, especially the strengthening degree of heat treated semi-solid die castings is much greater than that of liquid die castings with the tensile strength more than 330MPa and the elongation more than 10%, and this is mainly contributed to the non-dendritic and more compact microstructure of semi-solid die castings. The strengthening mechanism of heat treatment for the semi-solid die castings of A356 aluminum alloy is due to the dispersive precipitation of the second phase(Mg_2Si) and formation of GP Zone.

Parton Distributions of Pions in the Valon Model

Based on the universality of the parton distributions inside valons, parton distributions of pions are investigated and parametrized from the experimentally given parton distributions of proton within the valon model. The structure function F_2(x) is given at fixed scale Q_0~2 = 1 GeV~2. Due to the abundance of the pair numbers of sea quarks at a very small x region, the structure function decreases rapidly for small x to a local minimum. Then from the contribution of the valence quarks, F_2(x) increases to a local maximum at x approx = 0.5.
精神超脱量表编制的理论构思以及初步信效度检验

认知治疗是以认知心理学为理论基础，通过揭露患者歪曲的情感反应背后的否曲认知，并通过包括认知重建和行为试验等具体操作技术来改变这些歪曲认知，达到改变歪曲情感反应的目的的一种心理治疗方法，最初由A. Beck用于治疗抑郁症。其理论假设是认知影响行为与情感反应，歪曲的认知导致适应不良的行为和情感，导致相关疾病，纠正歪曲的认知及相应的情感与行为反应，就可以治疗这些疾病。基于认知治疗的理论，已经编制了几个用于测量有关抑郁的思维问卷。在进行道家认知治疗的过程中，我们发现在焦虑性神经症和一些心身疾病的患者中也普遍存在认知上的偏差。因此我们试图编制用于测量与此有关的认知的量表。

A Hybrid Spin-Down Model and its Application to the Radio Quiet X-Ray Pulsar 1E 1207.4-5209

A series of newly published papers are focusing on the formation of the absorption features discovered by Chandra and XMM-Newton from the young radio quiet x-ray pulsar 1E 1207.4-5209. We try to interpret it as cyclotron absorption lines since this possibility could not be ruled out. With new development and application of a hybrid model, i.e., the magnetic dipole spin-down model combined with the neutrino cyclotron radiation spin-down model, we can easily avoid the contradiction between the normal rotation energy loss rate and the relatively lower magnetic field, and then we obtain the possible initial spin period (～0.420 s). We suppose that the progenitor of 1E 1207.4-5209 may be a white dwarf.

On the predictability of chaotic systems with respect to maximally effective computation time

The round-off error introduces uncertainty in the numerical solution. A computational uncertainty principle is explained and validated by using chaotic systems, such as the climatic model, the Rossler and super chaos system. Maximally effective computation time (MECT) and optimal stepsize (OS) are discussed and obtained via an optimal searching method. Under OS in solving nonlinear ordinary differential equations, the self-memorization equations of chaotic systems are set up, thus a new approach to numerical weather forecast is described.
