| 摘要 |
The invention relates to a synthetic particle used for marking a substance. Said synthetic particle is comprised of a number of identification substances (10, 12), which exist in solid form, and of at least one covering (16), which encloses at least one of the identification substances (10, 12). The identification substances (10, 12) are selected such that the synthetic particle (18) can be identified by simultaneously identifying the identification substances (10, 12) in one and the same identification method on the basis of non-optical properties of the identification substances (10, 12). |
