The invention provides a surface flow measurement method based on a monostation shipborne high-frequency ground wave radar, belonging to the space-time processing field of shipborne high-frequency ground wave over-the-horizon radar signals and the ocean surface flow remote sensing field. The surface flow measurement method solves the problems of difficult synchronizing detection, small remote sensing field, high measurement cost and low observation efficiency of the traditional shore-based high-frequency ground wave radar which measures the surface flow vector field by using a two-station measurement scheme. A sea area to be measured is divided into a plurality of sector grids, and each grid is a detection unit; the position of actually measured positive / negative first-order Bragg spectral peak on each detection unit is obtained by a time-space joint spectrum estimation method and through spectrum search, and a radial flow velocity on the corresponding detection unit is obtained so that the radial flow field distribution of the measured sea area can be obtained; the optimal surface flow vector field on each unit is obtained by the least square method; the optimal surface flow vector fields which are measured in the same detection unit at a plurality of measurement moments are weighted and averaged so that the surface flow vector field of the measured sea area can be obtained. The surface flow measurement method based on the monostation shipborne high-frequency ground wave radar is specifically used for measuring the ocean surface flow.

Multi-layer microcapsule for room-temperature self repairing, and preparation method and application thereof

The invention discloses a room-temperature self repairing type thermoplastic polymer material based on a multi-layer microcapsule and a preparation method thereof. The thermoplastic polymer material comprises the following components in parts by weight: 70-95 parts of thermoplastic polymer base and 5-30 parts of filled multi-layer microcapsule for self repairing. The multi-layer microcapsule in the self repairing polymer material is a multifunctional intelligent multi-layer microcapsule combining a repairing agent and a catalyst. When a crack is generated in the base, the crack causes the capsule wall of the multi-layer microcapsule to crack together with the base, the liquid repairing agent at the capsule core part is released to be in contact with the catalyst on the middle capsule wall so as to initiate polymerization reaction at room temperature, and a generated new polymer bonds the cracked surfaces, thus preventing the propagation of the crack and repairing the crack. The multi-layer microcapsule used by the invention has moderate mechanical strength and favorable heat stability, and can endure the common thermal forming and processing technology of the thermoplastic material.
