The invention discloses a method for channel correction. In the method, different vacant subcarriers are used to carry known signals in different channels; the known signals carried by vacant subcarriers are sent to the local coupling through a corrected transceiver at the frequency point of the receiving channel. The device mixes the normal service signal from the antenna array with the signal from the correction transceiver, sends it to the normal transceiver for processing, and then sends it to the correction calculation unit. The correction calculation unit determines the estimated values ​​of the characteristics of different channels, and The determined estimated value is transmitted to the normal baseband processing unit, and the normal baseband processing unit corrects the corresponding channel according to the estimated value. The invention also discloses a transmitting channel correction system and a receiving channel correction system. The present invention adopts the mode of active transmission on the vacant orthogonal sub-carrier to automatically complete the channel correction, and the correction process has no influence on the normal business, thus does not affect the capacity of the system, and also does not affect the coverage of the system through the local loopback.

The invention discloses a battery vacuuming and sealing method and a vacuum extractor, relating to the battery production process field. The invention discloses a vacuum extractor which comprises a vacuum tube, a drying tube, an intermediate vessel capable of separating gas from liquid, and a needle. The method is as follows: the vacuum extractor is aimed at a liquid injection hole for vacuum extraction; gas, water and electrolyte are extracted into the intermediate vessel; the gas and the water are extracted from the vacuum tube with the electrolyte left in the intermediate vessel; dry air is blown from the drying pipe to get the electrolyte back to a battery; and finally the battery is sealed. The invention guarantees the electrolyte does not leak during the vacuum extraction. The vacuum extraction sealing method and the vacuum extractor of the invention can effectively get rid of harmful gases while guaranteeing the electrolyte in the battery is not extracted out or does not leak so as to influence the volume of electrolyte in the battery during the vacuum extraction, and, to some extent, reduce the thickness of the battery and guarantee the performance of the battery.
