平面波与球面波的差别是,The difference between a plane wave and a spherical wave is,A.平面波同一组波线穿过的面积不相等,球面波同一组波线穿过的面积不相等;The area of a plane wave through the same set of wave lines is not equal, and the area of a spherica
Additionally, in the test we directly observed some macroscopic phenomena, such as a large amount of fluid seeping out at the interface between the pile cap and the clay, as well as water spraying and sand emission at the weak part of the soil where the strings of the sensors were placed...
