We have a name for this, amorphous solids are isotropic.

我们为此起了个名字，非晶态固体是性的。

In addition, the soil is assumed to be an isotropic elastic material, and the plastic deformation of the soil is not considered.

此外，假设土壤是性弹性材料，不考虑土壤的塑性变形。

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.

反用了“结构性颗粒燃料”，其可裂变铀（以及氧和碳）的斑点被包裹在碳和碳化硅层中。

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.

考虑到简化计算，假设土体为均质、连续、性的半无限空间弹性体，地基不分层，隧道本身变形稳定。

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，深埋于性岩土中的圆形隧道周围的力和位移弹性平面变解。
