Abstract: A three-dimensional model topology-preserving deformation method based on multiple body harmonic fields, which belongs to the fields of computer graphics, computational mathematics, topology and differential geometry. The method comprises: firstly, constructing a tetrahedral mesh between an original three-dimensional model and a target three-dimensional model; then, on the basis of a traditional single body harmonic field, calculating a region in which topological transformation occurs during deformation; setting special multiple boundary conditions, and then calculating multiple body harmonic fields according to the special multiple boundary conditions; and finally, inducing topology-preserving curved-surface deformation. By means of the method, a region in which topological transformation occurs during deformation can be found on the basis of a saddle point in a traditional body harmonic field, and multiple body harmonic fields capable of inducing topology-preserving deformation are self-adaptively constructed, so that a topology-preserving deformed curved surface is generated under guidance of the multiple body harmonic fields. The method is universal and high efficient for deformation of three-dimensional models having the same topology, the calculation cost required by the method is lower than that required by traditional large-deformation diffeomorphic metric mapping, and the method can be widely applied.

Abstract: Provided in the present application are a chip and a memory, related to the technical field of semiconductors, for use in solving the technical problem of a low pass rate of chips. The chip comprises a substrate. A through hole running through the substrate is provided in the substrate. The through hole is provided with an electrically-conductive column. A first annular groove is provided on a first surface of the substrate. The first annular groove is provided around the electrically-conductive column. A first separating element is provided in the first annular groove. The first separating element is provided therein with a first air gap extended in the circumferential direction of the first annular groove. When heat stress is generated between the electrically-conductive column and the substrate, the heat stress is released via the first air gap in the first separating element, thus alleviating or preventing lattice deformation in the substrate outside of the first annular groove, reducing local delamination of the chip, mitigating the impact of the heat stress on electrical components on the chip, reducing failures of the electrical components, and increasing the pass rate of chips.
