  . 2005, 23(0504): 4-7.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  For the complexity of coordinated attacks, it is difficult to detect them efficiently by using the traditional methods such as misuse detection and anomaly detection. Based on the research work on the hiberarchy and reciprocity of attack behaviors, a solution for detecting coordinated attack with the conditional association and temporal method was suggested. A kind of attack representation that suitable to association analysis has been introduced.

  AN ANALYSIS ON RELIABILITY OF PERMAFROST ROADBED ENGINEERING OF QINGHAI-TIBET RAILROAD

  . 2005, 23(0504): 29-31.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  Permafrost has extensive temporal and spatial variability that is affected by many uncertain factors along Qinghai-Tibet Railroad, for example, uncertainty of climate change, engineering itself, change of permafrost engineering properties and permafrost change. The research was done through uncertain research methods. So the ideas of reliability evaluation must be introduced to analyze the change of roadbed stability. Spatial variability of permafrost and the variability of engineering properties of permafrost were analyzed, and the significance on the application of engineering reliability in the engineering stability of permafrost roadbed of Qinghai-Tibetan Railroad was discussed. According to engineering stability features of permafrost roadbed, possible disabled patterns of permafrost roadbed engineering were proposed. On the design principles of the roadbed in permafrost regions, variability design and evaluation of engineering stability for permafrost roadbed were developed.

  Currently, in many countries, technology foresight has been playing an important role gradually in formulating their science & technology policies. It will become more and more important with the establishment of our mid- to long-term science & technology layout. As a classical proposition from the ancient Greece, Achilles Paradox has a long-term effect on the development of modern maths and physics. What relationship is between technology foresight and Achilles Paradox? Based on illustrating the essence of technology foresight strategy, the formation of technology menu and the game rule of Archilles Paradox, the possibility in producing Archilles Paradox from technology foresight , and the prevention as well were analyzed

  POLICY AND COUNTERMEASURES TO CONTROL NON-POINT POLLUTION OF AGRICULTURE IN CHINA

  . 2005, 23(0504): 47-51.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  Non-point pollution is becoming one of the main causes of the degradation of rural environment in China. The status of non-point pollution was evaluated from chemical fertilizer and pesticide application, and the eutrophication of lakes. Excessive input of chemical fertilizer and pesticides, lower use efficiency of fertilizer and irrigation water, fewer treatment of organic manure from livestock husbandry, inadequate extension services and deficit environmental awareness are the reasons responsible for the non-point pollution. The countermeasures were suggested in respective to policy, legislation and technology.

  STUDY ON THE STABILITY AND ACTIVITY OF CuO/γ-Al2O3 IMPROVED BY Ce

  . 2005, 23(0504): 59-61.

  Abstract ( ) Download PDF ( ) HTML   Knowledge map   Save

  The three-element catalyst CuO- CeO2/γ-Al2O3 was prepared by layering and mixing impregnation method, in which CeO2 was chosen as the aids, γ-Al2O3 as the substrate, CuO as the active component. TD-DTA and XRD was carried out to investigate the effect of Ce on the stability of the substrate and the activated substance, CuO at high temperature. The results showed that the doping of Ce restrained effectively the phase change of substrate from γ-Al2O3 to α-Al2O3 and the formation of CuAl2O4 , which was produced by the reaction between CuO and Al2O3 during the process of wet air oxidation. The degradation experiment of phenol wastewater showed the doping of Ce can improve the activity of catalyst well. The catalyst with Cu∶Ce∶γ-Al2O3=6∶6∶100 (mass percentage) has the highest catalytic activity among them, the COD removal efficiency of which can reach 91.31% in 30 minutes.
