New 4-node special hybrid stress membrane elements with drilling degrees of freedom have been developed based on an extended minimum complementary energy principle. These elements are used jointly with conventional displacement elements for the analysis of stress concentrations around different holes and notches. The assumed stress field in the elements satisfies the equilibrium equations, the traction-free boundary conditions and the compatibility equations. Detailed numerical studies show the new special elements can provide accurate stress concentration factors and the distributions of circumferential stress along the rims of the holes when only very coarse meshes are used near holes and notches.

This paper describes an experimental investigation on flow boiling heat transfer and visualization of water in a steel micro-groove horizontally laid with rectangular cross section of 0.4×0.4mm².The mass flux G is ranged from 62.5 to 187.5kg/m²s and the inlet temperature T_in is set as 30,45 and 60°C. The results show that, under the condition of low vapor quality, heat transfer coefficient increases with the increase of vapor quality; and hold a certain value until the boiling crisis happes under high vapor quality. The augment of the mass flux could increase the heat transfer coefficient markedly, while the change of the inlet temperature has a weak influence on it. During the visual study, the emergence of great deal of bubbles is observed when the wall superheat is low. The main flow patterns found in the experiment are plug flow and annular flow.

A Rogowski Coil has been designed to measure of the discharging current of the plasma dynamic accelerator which has been developed recently. The principle of Rogowski Coil for measuring pulse current, the electric and geometric parameters of the coil and the ways to shield the coil from the electromagnetic interference have been analyzed. The measuring results has been presented and verified according to the theory of the circuit, and the elementary analysis for the source of the error has been obtained.

In this paper, the algorithm of wide area augmentation system (WAAS) ionospheric grid correction was tested using 15 GPS stations’ observational data. The span of data was from July 1 to 8 and from July 14 to 18, 2000, which represented quiet and disturbed geomagnetic conditions respectively. The paper discussed algorithmic accuracy and the emphasis was laid on the different latitude users and the stormy conditions. Using geostatistics method, this paper further analyzed the spatial correlation of ionospheric grid errors distribution in term of integrity and availability. The results show that precision is high for user stations in the middle-high latitudes with the average of around 0.4 meters，but it is relatively decreases for the lower latitude. The algorithm prediction error is larger under ionospheric stormy conditions, which is more prominent for the stations in the low latitudes. Correlation of residual error decreases with the great circle distance between pierce points increasing. For the ionospheric quiet behaviors residual error is small and correlation is high between neighboring errors, but it is the opposite for the storm time.

It is crucial for economic spatial structure to be industrial spatial division and specialization, and reasonable industrial spatial division takes advantage to use resource intensively and strengthen the regional competitiveness, and so on. Based on ways researching on industrial spatial division across the world, the article makes use of many ways, for example, industrial division exponential and specialization index and analyzes the whole manufacturing industrial division and division of important industry, taking the development zone along the river in Jiangsu as the sample. The article analyses the cause of industrial isomorphism based on H-O and industrial cluster theory. The conclusion is that the whole industrial division about development zone is clearly, and the information industry and metallurgy industry take on distinctly division. However, the partial industries are to some extent isomorphism, for instance, chemistry industry, mechanism industry and textile industry. The cause of isomorphism for chemistry industry and mechanism industry is the same for product elements. The cause of isomorphism for textile industry is that the area along Yangtze River in Jiangsu is traditional textile product zone. At the same time, it is still existing the problems on dispersing distribution of chemistry industry, smaller scope of mechanism industry and metallurgy industry, and so on. Finally, the article puts forward countermeasures to enhance spatial division of manufacturing industry in development zone along Yangtze River in Jiangsu.

Image watermarking resisting to geometric attacks is challenging at present. As typical geometric attacks, affine transformations can defeat most of existed watermarking schemes. Based on watermarking model with side information, a watermarking algorithm is proposed in this paper which is used of zernike moments of cover image. Employing dither modulation，watermark is coded and embedded by taking the zernike moments of the normalized image in the way of side information. It has been proved by experiments that this algorithm is high imperceptibility, high capacity, and robust to affine transformation and JPEG lossy compression.

In order to observe how acid environment of waste ore rock influences the seed germination of different species and the sensitivity of seeds to the acidity of waste ore rock, we designed the comparable groups of acidic solutions of different pH values to simulate the acidity of waste ore rock and examine the variations of seed germination for Amorpha fruticose Linn and Dalbergia hupeana Hance. We came to the conclusion that, at the pH value of above 2.4 for the indigenous environment of waste ore rock, Dalbergia hupeana Hance and Amorpha fruticose Linn are low acid-sensitive species. However, understanding their mechanisms of adaptation to the environment of acidic waste ore rock needs further physiological ecological experiments.

Rate distortion optimization technique takes an important role in video coding, which is widely used in many video coding modules, such as macroblock mode decision, quantization optimization, etc. In this paper, rate distortion optimization coding and optimal rate control is studied jointly. First, according to the analysis on the relationship between rate and distortion, a complexity scalable rate control is proposed. The proposed rate control algorithm can achieve better coding efficiency while with accurate target bit rate; second, buffer constraint for the bit allocation of rate control is studied, and the bit allocation process is adjusted to meet the buffer constraint, so that the proposed rate control algorithm can guarantee that the buffer never overflows or underflows; finally, a constant quality rate control algorithm is developed based on the research on some subjective quality issues, such as scene change detection, macroblock classification, etc.
