Abstract: The invention discloses a short process method for extracting precious metals by integrating thiosulfate electrochemical leaching and recovery, which includes: dissolving thiosulfate and an electrolyte, adding an alkaline solution, stirring evenly to obtain an electrolytic solution; adjusting the pH of the electrolytic solution to 7-13, then placing the electrolytic solution and materials containing precious metals in the electrolytic cell, and using an electrode system set in an electrolytic cell for electrolysis reaction, so that precious metals are leached at the anode and deposited at the cathode; collecting precious metals deposited on the cathode.

Abstract: The present invention discloses a phase shift system that is used for changing phases of signals transmitted to at least two radiation elements, comprising at least two phase shifters providing signals to the radiation elements, the phase shifter having a phase shift part used for moving so as to change phases of signals passing through the phase shifter. The system further comprises a phase shift drive device that is connected to the phase shift part of each phase shifter for synchronous linkage of all the phase shift parts, such that the phase shift parts move at different velocities to form a differential continuous phase distribution among the signals of the radiation elements. Through the above mode, the present invention can form a phase shift system with a relatively high number of ports by combining a plurality of phase shifters, and all the ports can form the differential continuous phase distribution.

Abstract: A multi-frequency array antenna, includes a reflective metal plate, a low-frequency radiation column element which is arranged on the reflective metal plate and operating in a first frequency band range, and a high-frequency radiation column element operating in a second frequency band range. The low-frequency radiation column element comprises several low-frequency radiation units arranged at an equal first distance in the axial direction of a first reference axis. The high-frequency radiation column element comprises several high-frequency radiation units arranged at an equal second distance in the axial direction of the first reference axis. The first distance is 2.5 times the second distance. At least one of the low-frequency radiation units is nested with one high-frequency radiation unit locationally corresponding thereto, and at least one of the low-frequency radiation units is axially located between two adjacent high-frequency radiation units close to the low-frequency radiation unit.

Abstract: A multi-frequency shared antenna comprises a low frequency radiation array and a first high frequency radiation array both of which are disposed on a reflection plate and provided with power by different feeding networks. The first high frequency radiation array comprises a number of high frequency radiation units, at least partial high frequency radiation units are arranged on a same axis which overlaps one of two axes of the low frequency radiation array, in all high frequency radiation units arranged on said axis, at least partial high frequency radiation units are nested with the low frequency radiation units arranged on the same axis, and the orthogonal projection area of these nested high frequency radiation units on the reflection plate falls within the orthogonal projection area of the corresponding low frequency radiation units on the same reflection plate.
