4.Copper conductive adhesives were prepared using epoxy as matrix, the mixture of m-phenylenediamine and diaminodiphenylmethane as hardener, and copper particles as the conducting filler.
3.The reactors use " tristructural isotropic particle fuel" , in which blobs of fissile uranium (along with oxygen and carbon) are wrapped in layers of carbon and silicon carbide.
4.Considering the simplified calculation, it is assumed that the soil mass is a homogeneous, continuous and isotropic semi infinite space elastic body, the foundation is not layered, and the deformation of the tunnel itself is stable.
5.Through theoretical analysis methods, Li and Wang determined the elastic plane strain solution of stress and displacement around a circular tunnel deeply buried in isotropic rock and soil under a uniform stratum load and internal pressure.
通过理论分析方法,Li 和 Wang 确定了在均匀地层载荷和内压下,深埋于各向同性岩土中的圆形隧道周围的应力和位移弹性平面应变解。机翻
