The invention provides a high-precision standard plate thickness fixed-point measurement and compensation system and method. The system comprises a base; the two-dimensional object carrying movement module is mounted on the base; the concentric-square-shaped support is fixed to the base and spans the two-dimensional object carrying movement module; the net-shaped precise object carrying platform is arranged on the two-dimensional object carrying motion module and is used for carrying a to-be-measured workpiece and accurately positioning the position of a measuring point; the first laser sensor and the second laser sensor are arranged on the upper side and the lower side of the concentric-square-shaped support; and the control system is in communication connection with the two-dimensional loading motion module, the first laser sensor and the second laser sensor, and is used for controlling the two-dimensional loading motion module to move, accurately positioning the position of the measuring point and calculating the thickness of the workpiece to be measured. A high-precision standard plate thickness fixed-point measurement and compensation system is formed through the high-precision laser sensor, the net-shaped precise object carrying platform and the control system, and the contour of a workpiece to be measured can be described.

The application relates to application of an iron porphyrin compound in preparation of a tumor metastasis inhibiting drug and belongs to the technical field of biological medicines. The iron porphyrin compound of the application inhibits tumor metastasis through a triple synergistic mechanism: first, the non-enzymatic catalysis mode is used to improve the intracellular NAD + level, the tumor cell metabolism is changed from glycolysis to oxidative phosphorylation, and the tumor cell metabolic flexibility is broken; second, keratin and intermediate filament protein overexpression is induced, the cell skeleton mechanical rigidity is enhanced, and the tumor cell deformation and migration are limited; and third, CD8 + T cells and M1 type macrophages are activated, the tissue immune surveillance is strengthened, the whole-chain metastasis process of tumor dissociation, intravasation, circulation survival, extravasation and colonization is blocked from the source, and the tumor metastasis key link is comprehensively inhibited.
