战国时代,知识阶层在研习《诗》《书》等经典的基础上,创作出模拟《诗》《书》文体的篇章,这种模拟行为表明当时人们对《诗》《书》的文体体式已有较明晰的认识,反映了文体观念的逐步自觉。上博简《交交鸣乌》《多薪》当是对《诗》的模拟,上博简《卉茅之外》《李颂》以及《楚辞·橘颂》则是在模拟《诗》的基础上的新变,为楚辞之先声。清华简《保训》可视作对《书》的模拟。在经典传承基础上的“尊体”与“破体”,促成了战国时代的“文体突破”。

Journal of Hydrodynamics 2006年第2期18卷 148-155页

The flow characteristics of a 2D slot jet vertically impinging on free surfaces are numerically investigated by the Large Eddy Simulation （LES） with a dynamic Sub-Grid Scale （SGS） model. The σ-coordinate transformation is introduced to map the depth-variable physical domain to a depth-uniform computational domain. The split-operator scheme, which splits the solution procedure into advection, diffusion and pressure propagation steps, is employed to solve the instantaneous velocity and pressure field. A fully nonlinear Lagrange-Euler method is used to compute the free surface elevation. The numerical results show that the jet retains good self-similarity in the Zone of Eestablished Flow （ZEF）, while the turbulence of jet shifts gradually from isotropic to anisotropic in the Zone of Surface Impingement （ZSI）. When the jet approaches the free surface, the centerline velocity decreases rapidly and the flow is deflected by the free surface. Two symmetrical surface jets are formed in the Zone of Horizontal Jets （ZHJ）. An approximate Guassian distribution of super-elevation is also formed on the free surface. The computed results are in good agreement with the available experimental data.

Evidence suggests that in the event of a fire accident, a certain number of building occupants escape through smoke-filled environments. Consequently, evaluating the corresponding evacuation performance under such life-threatening conditions is important for advancing fire safety analyses. This study aimed to develop a fire-integrated evacuation model to consider the effects of spreading fire hazards (i.e., radiation, temperature, toxic gas, visibility) on evacuees in a room fire evacuation scenario. Furthermore, a novel quantitative approach was introduced to evaluate evacuees’ local fire risks and stress levels according to their egress paths. The escape characteristics at various stages of fire development were studied as well. The results demonstrate that evacuation performance varies considerably depending on the severity of evacuees’ confronted fire hazard conditions, which emphasizes the importance of minimizing the pre-evacuation time in fire evacuation emergencies.
