Factors governing formation of todorokite at atmospheric pressure

science china Earth sciences 2005年第10期48卷 1678-1689页

Research Center for Eco-environmental sciences, Chinese Academy of sciences, Beijing 100085, china Huazhong Agricultural university Chinese Academy of sciences

Todorokite commonly occurs in Earth surface environments. The factors governing formation of todorokite, such as reaction temperature, metal ions, dissolved O2 and pH, were investigated in this paper. Results showed that the forming rate of todorokite and its crystallinity decreased with falling reaction temperature, and the effect of temperature was more significant than that of other parameters. Nature of metal ions in the interlayer of buserite precursor and the structure of the buserite precursor obviously affected buserite transformation into todorokite. Weak bonding between the metal ions and MnO6 layer of buserite was favorable to todorokite formation. The rate of todorokite formation was promoted at a lower temperature with appropriate bubbling of O2. The pH in the system slightly influenced the todorokite formation, and todorokite could also be formed in a weak alkali medium or in a slightly acidic medium. Aged buserite pre-cursor more easily form todorokite than the unaged one.

Spin-orbit coupling modification of photons to ray equation in inhomogeneous medium

Journal of Shanghai university(English Edition) 2011年第6期15卷 529-534页

作者：钟芳季沛勇 Department of Physics College of SciencesShanghai University

Based on the principle of general relativity,geometrization of interaction,the interaction of the inhomogeneous isotropic medium to light can be equated to a non-Euclidean geometry field just like the situation of gravity,i.e.,light travels in the null geodesic in the non-Euclidean curved space-time,which is equivalent to the Fermat principle for the inhomogeneous *** this paper,the propagation of light in an inhomogeneous media is studied by means of the effective metric *** modification to the classical ray equation of photons is derived from the geodesic equation of photon by considering the spin effect of photons,which is induced via the spin-orbit coupling of photons,and the corresponding Hamiltonian of photonis *** on the spin-orbit coupling of photon,a light splitting phenomenon emerges in the inhomogeneous media,which is the spin hall effect of photon.

A large number of hydraulic concrete structures have hidden defects such as cracks, erosion, freeze and thaw, thermal fatigue, carbonization. These hidden defects seriously affect the strength, stability and durability of structures. These problems are studied mainly by single monitoring or diagnosis methods at present. The integration of multiple monitoring and diagnosis methods is not applied widely. Besides, the analysis theory on these problems is not developed very well. The systemic study on the aging mechanism of hydraulic concrete structures, time- variation model and health diagnosis is still not enough. The support for engineering practice is limited. Aimed at these major scientific and technological problems and combined with specific projects, study on detection of hidden defects and health diagnosis of hydraulic concrete structure has been carried out. This study includes the following content: field non-destructive examination of hidden defects of hydraulic concrete structures, seepage detection, the construction of in-situ sensing system, the combination of field detection and in-situ monitoring, the mechanism of crack, freeze and thaw, erosion and carbonization of hydraulic concrete structure, mechanism of combination aging; time-variation model of hydraulic concrete structure, theories and methods for health diagnosis of hydraulic concrete structures.

第七届海内外青年设计与制造科学会议

作者： Yao Xifan college of Mechanical Engineering, South china university of Technology, china

Force control is an effective means of improving the quality and productivity of machining operations. However, One of the greatest difficulties in regulating metal cutting processes is that these processes are inherently nonlinear exhibit nonlinear, uncertain and time-varying characteristics. Robust control, or fuzzy logic control is a good control method for such uncertain and nonlinear systems. Robust control is traditional method used to design of uncertainty-tolerant feedback systems. Fuzzy logic control is particularly suited for those systems whose mathematical models are not known, complex, or time-varying, or nonlinear, and where human experience can play an important role. Robust PID and fuzzy controllers were developed to deal with the difficulty in machining processes to obtain constant cutting-force by adjusting the feed rate automatically under time-varying cutting conditions in this paper. Simulation and experimental results on machining processes show that both robust PID control and fuzzy control can deal with uncertainty and nonlinearity in the machining processes.

Synthesis of GaN nanorods on Si substrates with assistance of the vola-tilization of ZnO middle layers

引用

Rare Metals 2005年第2期24卷 110-114页

作者： ZHUANGHuizhao GAOHaiyong XUEChengshan WANGShuyun DONGZhihua HEJianting collegeofPhysicsandElectronics ShandongNormalUniversityJinan250014China

GaN nanorods have successfully been synthesized on Si(111) substrates via ammoniating ZnO/Ga2O3 films at 950 degrees C. Ga2O3 thin films and ZnO middle layers were deposited in turn on Si(111) substrates by r.f. magnetron sputtering system. ZnO volatilized at 950 degrees C in the ammonia ambience and Ga2O3 reacted to NH3 to fabricate GaN nanorods in the later ammoniating process. The volatilization of ZnO layers played an important role in the fabrication. The structure and composition of the GaN nanorods were studied by X-ray diffraction (XRD) and Fourier transform infrared spectrophotometer (FTIR). The morphology of GaN nanorods was investigated using scanning electron microscopy (SEM) and transmission electronic microscope (TEM). The analyses of measured results revealed that GaN nanorods with hexagonal wurtzite structure were prepared by this method.

An Approach of Trustworthy Software Design with Automatically Adapting Software Update

Wuhan university Journal of Natural sciences 2011年第5期16卷 391-398页

作者： LI Zhen TIAN Junfeng college of Mathematics and Computer Hebei UniversityBaoding 071002 Hebei China

In this paper, we merge software trustworthiness with software design and present an approach to trustworthy software design with an automatically adapting software update. First, software behavior and results can be expected and behavior states can be monitored when a software runs by introducing a trustworthy behavior trace on a software and inserting a checkpoint sensor at each checkpoint of the trustworthy software. Second, an updated approach of the trustworthy behavior trace for the software at the level of checkpoints is presented. The trustworthy behavior traces of the software for two versions can be merged adequately by constructing split points and merge points between two trustworthy behavior traces. Finally, experiments and analyses show that：（1） the software designed by our approach can detect and report the anomaly in a software automatically and effectively, so it has a higher ability of trustworthiness evaluation than the traditional software; and （2） our approach can realize the accurate update of the trustworthy behavior trace with a lower space overhead of checkpoints when the software updates.
