The present application provides a video search method and device. By matching the obtained analysis result with an index field generated by information integration of all tags, the matching range of the analysis results can be expanded on the basis of improving the utilization rate of all tags , thereby increasing the number of video search results presented to the user. It can be seen that the index field generated by the information integration of all the included tags is used to complete the matching of the analysis results, which can effectively solve the problem of the independence of multiple tags. And each has a corresponding index field, which causes the problem of not being able to hit all the tags corresponding to the parsing result at the same time, so that the recall rate of the video is improved on the basis of making full use of all the tags.

The invention discloses an impedance matching system and an impedance matching method. The system comprises a sweep frequency power supply, a matching device, a sensor, and a controller respectively connected with the sweep frequency power supply, the sensor and the matching device. The controller judges whether the output impedance of the sweep frequency power supply matches the impedance of a reaction chamber.
