The invention relates to a composite two-stage flue gas desulfurization and dust removal purification process for efficient desulfurization and dust removal of dust-containing and sulfur-containing high-dense phase flue gas. It consists of the front part and the first and second parts; the front part is a ceramic multi-tube dust collector or electrostatic precipitator, which performs a first-level dust removal on the flue gas and removes 90% to 99% of the dust in the flue gas; the first part is Venturi In the drying absorption tower, the sulfur dioxide in the flue gas reacts with the desulfurization liquid and is absorbed to realize primary desulfurization; the second part is a bag type desulfurization dust collector, which removes the desulfurization reaction products and performs secondary dust removal on the fine particles in the flue gas; The sulfur dioxide gas that has not been removed from the flue gas realizes two-stage desulfurization; the advantages of the invention are: simple process flow, optimal matching combination of equipment, low calcium-sulfur ratio, high desulfurization and dust removal efficiency, small system footprint, and less maintenance workload , Low operating costs and so on. The induced draft fan does not carry water and sticky dust, the exhaust gas temperature is high, and there is no steam "white fog" phenomenon. The desulfurization product is dry powder, which is convenient for storage, transportation and comprehensive utilization.

A narrow and light mobile radio antenna that requires convenient supporting metal fittings provided in a base station is provided. An inner conductor (1b) of a coaxial feed line (1) extends upward by a length of 1 / 4 wavelength from the upper end (1c) of an outer conductor (1a). This extended inner conductor (1b) forms an antenna element (3). Outside the coaxial feed line (1), a 1 / 4-wavelength sleeve-like metal pipe made of brass (2) is located with one end connected to the upper end (1c) of the outer conductor (1a). On a part of the inner surface of the open end of the metal pipe (2), an internal thread (2b) is formed by tapping. In the open end of the metal pipe (2), an insulating spacer (4) having an external thread (4a) formed around its periphery is inserted. In other words, the insulating spacer (4) is located between the inner wall of the metal pipe (2) and the outer conductor (1a) of the coaxial feed line (1). At the lower end (1d) of the coaxial feed line (1), a coaxial connector (5) for connection with an external circuit is provided.

The invention relates to a rock and explosive matching optimized blasting test method. The method includes: step shallow hole blasting funnel test and explosive and rock matching optimum analysis. The shallow hole blasting funnel test is carried out in a to-be-tested rock or ore area and adopts standard blasting crater test. The explosive and rock matching optimum analysis method includes: calculating the blasting crater volume, rock block average broken granularity, crack box dimension, seismic wave total energy, explosion energy time density and explosion energy utilization, making an explosive and rock matching analysis table, conducting groups of experiments, sorting and scoring the explosive and rock matching analysis table, and then determining the combination with the highest weighting score as the optimal matching of rock and explosive. By adopting the test method provided by the invention, and combining the explosive and rock matching analysis table, optimum matching optimization of different rocks of a mine and optional explosives can be realized.

The invention relates to the technical field of automobile cooling system matching, in particular to a method for testing and evaluating the performance of a truck cooling module suspension system. During the test, the test points are the radiator, the four corners of the intercooler and the main and auxiliary suspension positions of the cooling module. It is carried out in the assembled state of the whole vehicle. It can be tested in two states, one is when the vehicle is in neutral and not driving, No speed state; one is the normal driving state with the vehicle fully loaded. In the two states, test the vehicle engine idling operating condition, the engine rated speed operating condition, and the engine maximum torque operating condition. The sensors are used to test the above two states, and there are three working conditions for each state, and the data in six cases are obtained, and then the performance of the cooling module suspension system is evaluated according to the obtained data. The method of the invention can compare and evaluate the performance of different cooling module suspension systems matched with the truck, and the influence of the cooling module suspension system on the performance of the cold module, so as to guide product development.

The invention discloses a fault-tolerant method for message transmission of a network node and a network node, and relates to communication technology. After receiving a message segment sent by a sending end, the network node determines the error-containing message segment and determines whether the correct message is correct. After the segment is connected for data, due to the vacant position formed by the lack of the message segment, the complete message can be formed by matching the erroneous message segment with the vacant position, and no retransmission is required, which improves the communication efficiency of network nodes and reduces Communication energy consumption of network nodes.

The invention discloses a track matching method based on a genetic algorithm, which solves the problems of low track matching accuracy and large amount of calculation when there are many targets, many disturbances, and many mixtures. The implementation steps are: input the radar and surveillance system ADS-B track set; form the initial population; calculate the individual fitness of the population; competitive selection; gene crossover; gene mutation; If satisfied, the optimal result will be output, otherwise a new round of selection, crossover, and mutation will be performed to finally obtain the optimal set of track matching events. The present invention imitates the selection and genetic mechanism in nature, continuously removes poorly matched tracks, and retains better matches to ensure that the optimal result is finally found. The effect of finding the optimal matching result in a limited time is used for track matching between radar and surveillance system ADS-B.

The invention discloses a method for target re-identification in a multi-camera monitoring network, comprising the steps of: selecting image sequences of N pairs of targets between cameras i and j, and recording them as test image sequences and reference image sequences; obtaining camera i and camera The brightness transfer function between j; use the brightness transfer function to correct the color of the test image to be recognized to the same level as the reference image sequence; extract the ColorSIFT feature of each image in the test image to be recognized and the reference image sequence respectively and perform feature search and matching, and then according to KNN According to the saliency map and ColorSIFT feature, the two-way similarity is calculated, and the reference image corresponding to the maximum similarity is used as the matching target of the test image to be recognized, and the target is recognized. The method for target re-identification in a multi-camera monitoring network of the present invention solves the problem in the prior art that the target recognition rate is low due to insufficient utilization of the correlation of each image in the image data set.
