are concerned. Meanwhile, the plastic deformation energy of the blank was mostly converted into heat energy and internal energy. With the last method, the external heating is usually translated......
to several days. On the other hand, the energy of seismic waves from geological disasters was smaller than earthquake. Seismic waves can only propagate in rock and soil, not in the air. Therefore... of spatial sampling capabilities, there would be a large number of sidelobes on the ambiguity surface with high energy, which would not accurately locate the target. In addition, due to the limitation......
. In the process of preparing ceramic by additive manufacturing, high-energy beams such as lasers and electrons are usually used to melt the raw ceramic powder. However, severe internal stress caused by the rapid cooling during the melting of the high-energy beams greatly reduces the quality of the product. The indirect 3D printing technology of ceramic materials provides entirely new possibilities......
