Firms in China within the same industry but with different ownership and size have different production functions and face different emission regulations and financial conditions,thus can give very different responses to environmental *** fact has been largely ignored in most of the low-carbon development related *** an augmented Chinese input–output table in which information about firm size(large-and small and medium-sized firms)and ownership(state-,foreign-,and private-owned firms)are explicitly reported,a dynamic computable general equilibrium model is developed in this study to analyze the impact of alternative low-carbon policy designs with different regulatory coverage and financial equalization on heterogeneous *** simulation results show that,with the fully balanced regulation coverage and equalized financial system for heterogeneous firms,the total green investment accounts for 4%of GDP in 2030 for fulfilling China's commitment to reduce carbon emissions,which is the lowest among the various scenarios;about one-third of this investment is made by small and private firms;at the same time,green investment efficiency will be the highest,about 84%higher than that of the business-as-usual ***,a market-oriented and new technology-driven arrangement and mechanism for sharing emission reduction burden and allocating green investment across heterogeneous firms,especially to small and medium-sized firms,is crucial for China to achieve a more ambitious emission target in the long run.

Energy dissipation and contour integral characterizing fracture behavior of incremental plasticity

引用

Acta Mechanica Sinica 2011年第2期27卷 251-258页

作者： Qi-lin He lin-Zhi wu Ming li Hong-bo Chen Chen Center for Composite Materials Harbin Institute of Technology 150080 Harbin China

J ep -integral is derived for characterizing the frac- ture behavior of elastic-plastic materials. The J ep -integral differs from Rice’s J-integral in that the free energy density rather than the stress working density is employed to define energy-momentum tensor. The J ep -integral is proved to be path-dependent regardless of incremental plasticity and deformation plasticity. The J epintegral possesses clearly clear physical meaning：（1） the value J ep tip evaluated on the infinitely small contour surrounding the crack tip represents the crack tip energy dissipation; （2） when the global steadystate crack growth condition is approached, the value of J ep farss calculated along the boundary contour equals to the sum of crack tip dissipation and bulk dissipation of plastic zone. The theoretical results are verified by simulating mode I crack problems.

A Control Algorithm Derived from Immune Principle

Journal of China University of Mining and Technology 2006年第3期16卷 344-348页

作者： liU Jian-hua YAN De-kun wu li-bo School oflnformation and Electrical Engineering China University of Mining ＆ Technology Xuzhou Jiangsu 221008 China Department of Mathematics Linyi Normal University Linyi Shandong 276005 China

Artificial immune systems (AIS) are biologically inspired problem solvers having been successfully applied in many fields. A controller was designed according to the interactive mechanism between immune molecules. Multiform antigens were constructed and corresponding antibodies designed. The concept of “antibiotic” is presented, whose features and injection time as well as construction method discussed. Based on biological immune mechanism, some fuzzy rules are summarized and used in constructing the controller. The result shows that this controller is simple in structure and can be easily computed, so it is suitable for real time control. The control variable can change adaptively according to the error and its change tendency. Therefore the controller is very flexible and can be directly used in controlling some nonlinear plants. To test the validity of the algorithm, two simulation examples are given, one is linear, and the other is nonlinear. The Simulation results indicate that the control performance of this algorithm is better than that of the conventional PID.

To compare the oligonucleotide chip, real-time PCR and sequencing for genotyping of hepatitis B virus in Chinese patients with chronic hepatitis B. METHODS： Mixture of samples with different genotypes and clinical serum samples from 126 chronic hepatitis B patients was tested for hepatitis B virus genotypes by oligonucleotide chip, real-time PCR and sequencing of PCR products, respectively. Clinical performances, time required and costs of the three assays were evaluated. RESULTS： Oligonucleotide chips and real-time PCR detected 1% and 0.1% genotypes, respectively, in mixed samples. Of the 126 clinical samples from patients with chronic hepatitis B, genotype B was detected in 41 （33%）, 41 （33%） and 45 （36%） samples, and genotype C in 76 （60%）, 76 （60%） and 81 （64%） samples, by oligonucleotide chip, real-time PCR and sequencing, respectively. Oligonucleotide chip and real-time PCR detected mixed genotypes B and C in 9 samples. Real- time PCR was the rapidest and cheapest among the three assays. CONCLUSION： Oligonucleotide chip and real-time PCR are able to detect mixed genotypes, while sequencing only detects the dominant genotype in clinical samples.

Qualitative analysis and quantitative simulation on Yin-Huang water salinization mechanism in Bei-Da-Gang Reservoir

Journal of Environmental Sciences 2005年第5期17卷 853-856页

Yellow River water transfer for Tianjin is important in solving the water shortage in Tianjin, which facilitate economic development and social progress for many years. Fresh water drawn from Yellow River（ i. e., Yin-Huang water） becomes saltier and saltier when being stored in the Bei-Da-Gang reservoir. We qualitatively analyze the water salinization mechanism based on mass transfer theory. The main factors are salinity transfer of saline soil, evaporation concentrating, and the agitation of wind. A simulative experimental pond and an evaporation pond were built beside the Bei-Da-Gang reservoir to quantitatively investigate the water salinization based on water and solute balance in the simulative pond. 80% of increased [Cl^-] is due to the salinity transfer of the saline soil and the other 20% is due to evaporation concentrating, so the former is the most important factor. We found that the salinization of Yin-Huang water can be described with a zero-dimension linear model.

基于变权理论的煤层底板突水脆弱性评价模型可以解决传统常权脆弱性评价模型中存在的固定权重不能反映突水主控因素指标值内部差异性对评价结果造成的影响。但是利用变权模型对煤层底板突水评价中变权区间阈值及调权参数的确定目前尚没有统一的分析确定方法,变权区间和调权参数决定了变权模型对研究区主控因素的哪些指标值采取何种幅度的权重调整。针对这两个亟待解决的问题,根据煤层底板突水各主控因素指标值在空间分布上存在差异,但也具有一定的相似性的特征,利用聚类分析方法对各主控因素变权区间阈值进行了确定,同时也对变权评价模型中的调权参数确定探索性提出一种能够满足决策者决策偏好的可行性方法。在此基础上以山东省兴隆庄矿为例进行求解说明和效果验证。

Transient dynamic behavior of the excited bacteriorhodopsin (BR), which was isolated from the strain H. salinarum, was studied at excitation wavelength from 585 to 639 nm. With the one-color femtosecond (fs) pump-probe technique, we revealed the primary events in BR's photocycle that took place in an ultrafast time scale. From the analysis of the decay components of the dynamical traces, it was evident that the isomerization of the retinal

随着电子图书的发展和数字设备的普及,电子书阅读客户端日益成为用户阅读图书的重要工具。文章整合UTAUT和VAM模型,引入感知价值变量,考察影响用户对电子书阅读客户端使用意愿的相关因素。问卷调查和数据分析表明:(1)感知价值存在中介效应,感知价值在感知有用性和使用意愿之间扮演的是完全中介角色,而在感知趣味性、感知易用性、感知价格、社会影响和使用意愿之间发挥的则是部分中介的作用。(2)感知收益的两大维度,感知趣味性对用户使用意愿的解释力大大高于感知有用性。(3)社会影响不仅对用户使用意愿存在直接和间接效应,而且总效应在所有自变量中仅次于感知趣味性。
