Based on the research of the plots in coastal areas in Jiaonan city, shandong Province, the indices of richness, evenness and diversity of different community types are analyzed. The results show that: The richness indices indicates that arbor layers are close to shrub layers, and both are lower than herbage layers; the ranges among communities vary a little except those of the arbor ones. Mostly the biodiversity indices reveal that herbage, the arbor, the shrub; Biodiversity of communities has great influences on microclimate to a certain extent and is under the control of regional environment.

Energy is now becoming the bottleneck of urban and regional development. The paper takes shandong Province, one of the most energy consuming provinces in china, as an example, uses quantity methods such as SPSS (Stastics Package for Social Science) cluster sampling and regression analysis, and applies quantity analysis, to analyze the situation of energy issues in shandong province. The conflicts between the quick industrialization and increasing extensive economic development, between urban population and energy consuming per head, between the infinite energy consuming desire and the low level of managing system, and between the unstable world energy supply and the limited energy storage in china are the main factors of energy crisis in shandong, which not only results in energy shortage, but also becomes the barrier of economic and social development. In order to ensure sufficient energy supply for shandong province in the 21st century, we should take countermeasures, such as changing the economic development model, pursuing a multiple and high quality energy strategy, improving the intensive urbanization strategy, and building a scientific energy system.

Mutual Conversion of Land Use between Urban and Rural Area in the Process of Urbanization: A Case Study of shandong Province

引用

Chinese Journal of Population,Resources and Environment 2007年第2期5卷 93-96页

作者： Xu Hong College of Population, Resource and Environment, shandong Normal University, jinan shandong 2.0014, china College of Population Resource and Environment Shandong Normal University Jinan Shandong 250014 China

Urbanization is one of the driving forces for the land use change in type and structure, and its prominent effect is to convert rural land to urban land. This paper takes Shan-dong Province as an example to analyze the current situation of the mutual conversion between the urban and rural areas from the aspects of the structure of land use, the decreasing tendency of the cultivated land, the changes of land use in urban and rural residential areas. It points out that cultivated land is converted to residential area land, industrial and/or mining area land. The relationship between the urban area land and the cultivated land is more direct; meanwhile, the changes of rural residential area lag behind obviously. The decrease of the cultivated land and the decline of soil quality will be the two difficult problems in the process of urbanization.

The Effect of Anti-Human CD134 Monoclonal Antibody on Phytohemagglutinin-Induced mRNA Expression of Perforin in Peripheral Blood Mononuclear Cells

Cellular & Molecular Immunology 2005年第6期2卷 467-471页

作者： Ming Li~1 Yuanchao Zhang~(1,2) ~1Department of Rheumatology and Immunology,shandong Provincial Hospital,shandong University,jinan 250021,china ~2Department of Rheumatology and Immunology,shandong Provincial Hospital,shandong University,jinan 250021,shandong,china.

CD134, a member of the tumor necrosis factor receptor superfamily, plays a crucial role in T cell survival. In this study, peripheral blood mononuclear cells （PBMCs） stimulated with phytohemagglutinin （PHA, 50 μg/ml） were treated by CD134 mAb （1μg/ml, 5 μg/ml, 10 μg/ml） for 6 h, 12 h, 24 h and 48 h. The level of perforin mRNA was measured by reverse transcription-polymerase chain reaction （RT-PCR） technique. Our data showed that the expression of perforin mRNA in PBMCs was down-regulated by CD134 mAb in a dose-dependent manner in range of 1 μg/ml to 5 μg/ml and dropped down to its minimum on 24 h （p 〈 0.05）. The level of perforin mRNA reached a plateau when the concentration of CD134 mAb exceeded 5 μg/ml. In conclusion, CD134 mAb can inhibit perforin expression, which may enhance the ability of T cells for survival. Cellular ＆ Molecular Immunology. 2005;2（6）： 467-471.

Mechanical model of vulnerable atherosclerotic plaque rupture

Rupture of atherosclerotic plaque is the main trigger of acute cardiovascular events, but the mechanism of plaque rupture is still unknown. We have constructed a model describing the motion of the fibrous cap of the plaque using the theory of elastic mechanics and studied the stability of the plaque theoretically. It has shown that plaque rupture is the result of a dynamic interplay between factors intrinsic to the plaque itself and extrinsic factors. We have proposed a new mechanism of plaque rupture, given a new explanation about the nonlinear dynamic progress of atherosclerosis and suggested a method to identify the vulnerable plaques to manage atherosclerosis.

Adaptive bidirectional diffusion for image restoration

Science china(Information Sciences) 2010年第12期53卷 2452-2460页

作者： FU ShuJun 1,2 & ZHANG CaiMing 1 1 School of Computer Science and Technology, shandong University, jinan 250101, china 2 School of Mathematics, shandong University, jinan 250100, china 1. School of Computer Science and Technology Shandong University Jinan 250101 China2. School of Mathematics Shandong University Jinan 250100 China

A large number of applications in image processing and computer vision depend on image quality. In this paper, combining the forward diffusion with the backward diffusion by different weights, we present an adaptive bidirectional diffusion method for image denoising and deblurring simultaneously. Further, we introduce a gradient factor into the data fidelity term, which forms a spatially varying constraint and allows a better restoration of image edges and fine details. In order to obtain a stable solution, we develop a numerically stable scheme and give its theoretical analysis. Finally, we show advantages of this method in deblurring edges, denoising and restoring fine details of image compared with other related methods in experiments.
