The consistency of the continuum hypothesis 連續(xù)統(tǒng)假設的一致性
Set theory and the continuum hypothesis 集合論和連續(xù)統(tǒng)假設
Due to the complexity of porous media , the analytical theory about porous media seepage must be based on the method of porous media continuum hypothesis 由于多孔介質本身的復雜性,多孔介質滲流問題的分析理論往往需要在多孔介質連續(xù)介質方法的基礎上進行。
On the basis of the entropy expression of viscous flow , the entropy expression of porous media seepage under porous media continuum hypothesis is studied and put forward , and their unification is verified in pipe model 本文基于流體粘滯流動過程的熵產(chǎn)表達,研究提出了多孔介質連續(xù)介質方法下多孔介質滲流過程的熵產(chǎn)表達形式,并在平直管模型中驗證了兩者的統(tǒng)一性。
The research and contribution in detail are introduced as follow : ( 1 ) the driver characteristics > motor vehicle characteristics , road characteristics , macroscopic and microscopic flow parameters are analyzed . a new traffic flow continuum hypothesis is proposed . the compression index and elasticity coefficient are defined 具體工作如下: ( 1 )綜合分析了交通流中駕駛員的交通特性、車輛的交通特性、道路的交通特性、交通流的宏觀參數(shù)和微觀參數(shù),提出了新的交通流連續(xù)性假設,定義了衡量交通流壓縮性的壓縮系數(shù)和彈性系數(shù),分析了各種速度-密度模型所對應的壓縮系數(shù)。
