摘      要：正Based on the hybrid hypersingular integral equation-Lattice Boltzmann method（HHIE-LBM）,the typicalextended 3D flow driven pore-crack network Fukushima Nuclear plant leak accident model is established and thepenetration and diffusion process of Cesium-137 at different temporal spatial scales have been *** shownin Figure.1 the multi temporal spatial scale Fukushima Cesium-137 penetration and diffusion D3Q27 LBM modelis *** analyze the problem at different scale,four kind of scales[scaleⅠ（E140.25°～141.021°;N37°～39°）,scaleⅡ（E139.4°～142.4°;N35.8°～38.8°）,scaleⅢ（E140.15°-141.65°;N36.55°～38°） and scaleⅣ（E140.4°～141.4°;N36.8°～37.8°）]penetration and diffusion model are defined in our simulation *** penetration and
