This paper describes an atmospheric dispersion field experiment performed on the coastal site of nuclear power plant in the east part of china during 1995 to 1996. The three-dimension joint frequency are obtained by hourly observation of wind and temperature on a 100m high lower; the frequency of the 'event day of land and sea breeze' are given by observation of surface wind and land and sea breezes; the diffusion parameters are got from measurements of turbulent and wind tunnel simulation test. A new model calculating the annual mean atmospheric dispersion factor for coastal site of nuclear power plant is developed and established. This model considers not only the effect from mixing release and mixed layer but also the effect from the internal boundary layer and variation of diffusion parameters due to the distance from coast. The comparison between results obtained by the new model and current model shows that the ratio of annual mean atmospheric dispersion factor gained by the new model and the current one is about 2.0.

提出一种基于动态地形特征参数约束的多样图纹理合成算法。该算法采用多种纹理构建样本系统,以动态地形本身特点确定的函数作为约束条件,采用扫描线顺序,逐点计算每一像素点的RGB值,最终合成动态地形纹理。通过改变约束条件,该算法可以合成相应的纹理,为动态地形纹理合成提供了一种新的手段。实验证明该算法能有效的合成动态地形纹理,解决了仅使用多样图合成算法合成结果随机性大、不能控制某种纹理在合成结果图中的位置问题,在动态地形仿真中取得很好的效果。

关键词：纹理合成动态地形扫描线函数约束

Nuclear stopping in heavy-ion collisions over a beam energy range from SIS and AGS up to SPS is studied in the framework of the modified Ultrarelativistic Quantum Molecular Dynamics transport model (UrQMD),in which mean field potentials of both formed and"preformed"hadrons(from string fragmentation) and medium-modified nucleon-nucleon elastic cross sections are *** is found that nuclear stopping is influenced by both the stiffness of the equation of state and medium modifications of nucleon-nucleon cross sections at SIS *** high SPS energies,a two-bump structure is shown in the experimental rapidity distribution of free protons,which can be understood by considering the preformed hadron *** details,please read.

对于通用带式输送机运行阻力 ,现行的计算方法是用一个托辊运动阻力系数来计算其主要阻力 ,这种方法没有充分体现胶带的性能 ,这对于短距离通用带式输送机来讲 ,精度是足够的。目前带式输送机的发展趋势是长距离、大运量、高带速 ,输送带带芯材料的改善 ,使得带的张力越来越大 ,上述的计算方法就显的过于简单。特别是动态计算与设计方法的日趋重要 ,计算工具的日趋完备 ,所以有必要对输送带运行阻力进行仔细分类和理论分析。
