摘要：
Based on complex networks theory and evolutionary game theory, a evolutionary game model on complex networks is proposed and is simulated. The simulation results show that, though ESS is still subject to relative frequencies of initial strategies and payoffs matrix, network structures can change evolutionary stable strategy (ESS). Evolutionary game model on complex networks has different performance from general game models. Evolutionary equilibrium is easy to obtain while players are 'stupid' and or else it is hard to obtain.

摘要：
This paper proposed a Proportion-Integral(PI) control algorithm based design and its Programmable Logic Device (PLD) based prototype for all Digital Phase-Locked Loop (all DPLL). And relevant theoretic computation and computer aided simulation have also been implemented. It indicates that our proposed all DPLL is characteristic of its simple structure, high control precision, wide phase scope, tunable performance and easy system integration, etc.. It avoids the influences of negative factors that exist in simulative Phase-Locked Loop such as saturation and zero excursion on system performances. This DPLL has potential applications on a wide range of fields such as precision measure instruments, through which infinitesimal frequncy change can be implemented, and velocity or distance mesurement, and motor timing system, etc.

摘要：
In order to determine exposure to natural sources of radiation for people in the vicinity of a south China uranium company, six sites included a school, a hospital and four residential areas were investigated from September 2002 to March 2003. The surveys evaluated indoor radon concentrations and outdoor and indoor external gamma dose rates. Indoor radon concentrations were measured in 98 dwellings by means of nuclear track-etched detectors. The terrestrial gamma ray dose rate was measured outdoors and indoors at a total of 148 points and 85 points, respectively. The results show that the total mean annual effective doses for the six areas studied ranged from 3.6 to 5.9 mSv per year, which is between 1.8 and 2.8 times higher than the Hengyang average value. Applying the BEIR VI model to the areas studied, the population-weighted average lifetime risk of lung cancer can get 1.9 x 10(-4).
摘要：
The paper establishes a technique to prevent the accidents in a nuclear power plant on the basis of a quantitative analysis. A safety AHP (The Analytic Hierarchy Process) method is put forward on the basis of the establishment of expert ability weight and safety matrix. The common AHP technique is modified from two aspects: one is the expert weight, the other is to construct a safety matrix. This is to make the common AHP safer and can be applied to provide a qualitative support in decision-making in a giant social-technical system which needs a high safety safeguard, e.g. a NPP. The paper uses a case in a certain NPP in China to illustrate it and the casual factors in connection with the events are arranged in sequence to lead to a reasonable decision-making in a giant social complex. The technique can be widely applied in the giant social systems of high risk to prevent the happening of accidents.
摘要：
This paper proposes a novel coordinated nonlinear auto-disturbance-rejection controller (ADRC) for the excitation system and the static var compensator (SVC) of a four-bus power system. In the paper, a new dynamic feedback linearization method based on a nonlinear extended state observer is introduced, and the anticipating dynamic characteristic design for the linearized and decoupling system is also explicated. The coordinated controller can effectively ensure the stability of the power angle as well as the terminal voltage of the generating unit. Simulation results show that the proposed controller has excellent control performance with outstanding adaptability and robustness against external disturbances and model uncertainties.

摘要：
There is a huge mined-out area with a volume of 3 million m<sup>3</sup> in the Middle Section of the underground Xishimen Iron Mine in Hebei province, China. The existence of this mined-out area is a great threat to the mining operations under it. If the rock roof of the mined-out area caves in, the accompanying strong blastwave will be strong enough to blow out the workers and equipment at the lower level. This paper summarizes the possible measures to deal with this mined-out area through geological investigation, theoretical analysis, and on-site observations. The major measures studied in this paper include: blocking the drifts connecting to the mined-out area with isolating strips, taking reasonably stoping sequences to decrease the ground pressure, leaving protective layers and safety pillars, delineating the surface subsidence limits, and monitoring the surface rock movements, etc.
摘要：
Type 2 diabetes is a major risk factor of the development of atherosclerosis in humans. However, studies examining mechanisms underlying diabetes-accelerated atherosclerosis have been limited by the lack of suitable humanoid animal models. Pigs have a cardiovascular system that is very similar to that of humans and is useful as a model for human physiology and pathophysiology. In this study, we established a new miniature pig model for studying dyslipidaemia and atherosclerosis in diabetes. Chinese Guizhou minipigs were fed a normal control diet or a high-fat/high-sucrose diet (HFSD) for 6 months. Plasma total cholesterol (TC), high-density lipoprotein cholesterol, triglyceride (TG), insulin and glucose were quantified at monthly intervals. The induction of insulin resistance and dysfunction of the pancreatic β-cell were assessed by oral glucose tolerance test and insulin sensitivity test. The aortic fatty streak lesions were quantified following lipid staining with Sudan IV. During the feeding period, mild high plasma TC and TG were induced. At the end of 6 months, in HFSD-fed animals, the adipocytes were hypertrophic, fat deposit in the liver was observed, loss of pancreatic β-cells was observed, and the aortic fatty streak lesions were clearly present in the animals' aortas. Our study established that miniature pigs that were fed a HFSD without adding dietary cholesterol developed insulin resistance, mild diabetes and atherosclerotic lesions. HFSD-fed miniature pigs may be good animal models for research on the treatment of diabetic dyslipidaemia complicated with atherosclerosis.

摘要：
Liquid desiccant air conditioning systems (LDAS) are being studied as an alternative to conventional vapor compression refrigeration systems due to their energy conservation and environmental protection. The principle and characteristic of LDAS have been presented in this paper. A three-step LDAS is put forward based on the idea of stepping dehumidification and the principle of energy step utilization. This system driven by gas consists of fan, dehumidifier, evaporative cooler and regenerator. The dehumidifier uses the liquid desiccant to remove the water vapor of supply air by three steps. In every step there is a direct evaporative cooler to cool the course of dehumidification. The evaporative cooler is a combination of indirect and direct evaporative cooling, which is used to decrease the dry-bulb temperature of the dry air after dehumidification. The regenerator driven by gas makes the weak desiccant coming from the dehumidifier to renew by boiling and non-boiling evaporation. It is set forth that the characteristics in the way of saving-energy and improving IAQ about this system.

摘要：
The vibration characteristics of inertial vibration feeders were analyzed. Combining active with passive vibration isolation, the hybrid vibration isolation of inertial vibration feeders was researched. Adopting the passive vibration isolation, the vibration transmissibility can be reduced effectively, but the work efficiency of the inertial vibration feeder is reduced too. By choosing right feedback variables and appropriate feedback gain, the vibration transmissibility and the work efficiency of the inertial vibration feeder can be improved markedly by the hybrid vibration isolation. When the velocity feedback gain is equal to the upper damping coefficient and the displacement feedback gain is equal to the upper spring stiffness, the inertial vibration feeder has the best work efficiency and the vibration transmissibility approximates zero. The fuzzy PID control approach was used to design the active vibration control system. The simulation results show that the developed active vibration control system has good control performance.

ultra-precision grinding machine;vibration isolation;giant magnetostrictive actuator;robust control
摘要：
A 6-degree-of-freedom vibration isolation system for an ultra-precision grinding machine has been developed. This system uses air springs as passive vibration isolation elements and giant magnetostrictive actuators as active vibration isolation elements. The displacement and velocity of the ultra-precision grinding machine can be chosen as the output feedback variables for the controller. With the H<inf>∞</inf>/μ, frequency shaping synthesis theory, a robust controller can be designed for the ultra-precision grinding machine, which is a nonlinear control system with uncertain disturbances. The method has an advantage comparing with the linear feedback control method, with which the dynamic performances and control accuracy of the system may become worse while the nonlinearity and disturbances exist. The simulation results show that the new vibration control method has stronger robustness, better dynamic performances and higher control accuracy than the common linear feedback control method.

Gold grade;space series;chaotic analysis
摘要：
A new powerful tool, chaotic theory, has been used to study mineralization through chaotic analysis for space series of gold grade in this paper. Both of the most important chaotic measures, Largest Lyapunov exponent (LLE) and fractal dimensional, for space series of gold grade in one gold deposit are computed. The positive LLE suggests that the space series of gold grade are chaotic series. When the phase space dimension approach 8~10, a chaotic attractor appears and their fractal dimension values vary from 1.94 to 3.99. It indicates that the evolution of ore-forming fluid and the enrichment and deposition of gold element are chaotic dynamic process.
