| 1 | Development of a model to generate a risk map in a building fire显示文摘Fire simulations and sensors are widely used in building fires,various data such as temperature,CO and CO2 concentration,visibility can be obtained by sensors and sensor-based simulation. It is important to generate a risk map based on such data so that we can use it to estimate safety of the building. In this paper,we propose a method to generate a dynamical,integrated risk map using sensor readings in a building fire. Such risk evaluation model is developed using similarity comparison between the space state and dangerous state by a likelihood distance calculating and data grouping from a two-step cluster method. The risk evaluation model considers the integrated influence on the occupants in the zone from high temperature,lack of oxygen,toxic and harmful gases and shows the relative fire risk map at certain time. Based on the simulation study,it is proved that multi-factor fire risk analysis would be more objective and accurate than single factor and two-factor risk analysis and the fire risk evaluation model can generate a risk map and provide the classification information and the whole building risk statistic results to support evacuation command and control. | CHU YanYan, ZHANG Hui, SHEN ShiFei, YANG Rui & QIAO LiFeng Center for Public Safety Research, Department of Engineering Physics, Tsinghua University, Beijing 100084, China | 2010 | Science China(Technological Sciences)2010，53，10： | 4 |

| 4 | The numerical simulation of caesium-137 transportation in oceanand the assessment of its radioactive impacts after Fukushima NPP release显示文摘After the damage of Fukushima Daiichi Nuclear Power Plant, a great number of radioactive materials were released into the Pacific Ocean. Therefore, it is necessary to research on the temporal and spatial distribution of these radionuclides. We use Princeton Ocean Model to simulate the circulation of the coast water of Fukushima NPP and obtain the concentration of caesium-137 by solving the diffusion equations. We employ the Monte Carlo N-particle(MCNP) code to assess the external doses caused by these contaminated sea water. To improve the efficiency and effectiveness of volume source in MCNP code, we establish a transformation method between spot source and volume source, and determine an appropriate range of volume source. Finally, we calculate the absorbed doses of every organ/tissue and the effective dose of a human body. | GUAN Yue SHEN ShiFei HUANG Hong | 2015 | Science China Earth Sciences2015，58，6： | 0 |
