Abstract: A selective catalytic reduction (SCR) system, comprising a box body, a mixer, a baffle and a carrier, the mixer, the baffle and the carrier being sequentially arranged inside the box body in an airflow direction inside the box body, the baffle being provided with a plurality of through holes, and the distribution density of the through holes and/or the hole area of the through holes being negatively correlated with a distribution uniformity index of NH3 at the baffle. The configuration of the distribution density and the hole area of the through holes can improve the mixing uniformity of ammonia gas, so that a reaction effect of a catalyst and a mixed gas in the carrier is enhanced. The settings of the distribution density and the hole area of the through holes can improve the mixing uniformity of an ammonia gas.

Abstract: An intent negotiation method and apparatus are provided. The method includes: A first network element sends a first sub-intent of a first intent to a second network element, and sends a second sub-intent of the first intent and indication information to the second network element, where the indication information is used to indicate that the first sub-intent and the second sub-intent have a same action and a same object.

Abstract: A method for associating intent knowledge between intent systems, an apparatus, and a system. When intent knowledge of a first intent in a first intent system is updated, a second intent system receives an intent knowledge update notification sent by the first intent system. The intent knowledge update notification includes an update type and an intent keyword of the first intent. The second intent system associates, based on the intent knowledge update notification, the intent knowledge that is of the first intent and that corresponds to the intent keyword of the first intent with intent knowledge of a second intent in the second intent system. In this way, the intent knowledge is associated between the intent systems, to avoid that the intent knowledge of the first intent in the second intent system is missing or invalid.

Abstract: This application discloses a communication method, apparatus, and system. In this application, a first network element obtains first knowledge of a first intent, where the first knowledge of the first intent includes one or more chosen from the following: a first reliability of fulfilling a first intent target and first information. The first reliability indicates the reliability of fulfilling the first intent target, and the first information indicates the impact of a first intent operation on a second intent. The first network element selects a first operation based on the first knowledge of the first intent for executing the first intent. The first network element may select the first operation based on the reliability of fulfilling the first intent target and/or the first information, to improve accuracy of selection of the first operation.

Abstract: The present invention relates to a demodulation method for enhancing decoding performance of information bits in a constant-amplitude multi-code biorthogonal modulation communication system, which performs encoding to cause the level of a transmission symbol to be constant. In the demodulation method of the present invention, a demodulator demodulates the received signal, the demodulator having four blocks. C (c?2k, k is the number of information bits) bit streams with higher correlation values in descending order are selected and combined among demodulated bit streams to establish c4 bit stream candidates. A parity check is performed with respect to the c4 bit stream candidates, a candidate group having a maximal sum of correlation values is selected among candidate groups in which any error is not generated at the parity check. A bit stream corresponding to the selected candidate group is determined to be an output of a receiver.
