The invention relates to a corrugated steel web formation device, and discloses a bending and compression combination-type corrugated steel web formation device, which comprises a punching mechanism and a bearing mechanism which is arranged below the punching mechanism, wherein the punching mechanism is provided with a compression bracket and two bending brackets which are arranged at the left and the right sides of the compression bracket, the compression bracket is provided with a force application projection, a male mould is embedded on the force application projection, the bearing mechanism comprises a lower mould frame and a female mould which is arranged on the lower mould frame, the lower mould frame is provided with a bearing groove which is matched with the female mould, the female mould is embedded inside the bearing groove, a steel web to be processed is arranged between the punching mechanism and the bearing mechanism, and the lower bottom part of the bending mechanism is provided with an arc wing plate. The device integrates the compression and the bending. Less than two points on a uniform cross section are stressed when forming the steel web, so the crackles which are formed because the formation surface is easy to be stretched and become thin can be prevented; and moreover, the formation power is small, and the rebound difference is small.

The invention relates to a method and a system for extracting complex named entities from Web video pages. The method comprises the following steps: step 1: extracting effective text information from each Web video page in a Web video page set, wherein the effective text information forms video texts, and all video texts form a training set; step 2: classifying the Web video pages, selecting classifications, setting guide words for each selected classification, and selecting words which are related to the guide words and are uniformly and intensively distributed among the classifications fromthe training set as characteristic words; and step 3: extracting the words which are related to the characteristic words from the training set as candidate complex named entities, and selecting corresponding complex named entities for each selected classification from the candidate named entities according to the correlation degree of the classification with the characteristic words related to the candidate named entities. The method and the system of the invention can be used for extracting complex named entities from Web video pages without carrying out model training for a long time.

The invention relates to the field of household appliances, discloses an information processing method and an air conditioner and aims to solve the technical problem that detecting failures of a cooling system by the prior art is not timely enough. The information processing method is applied to the air conditioner and includes: detecting sound information of a throttle device of the air conditioner by a sound detector provided for the air conditioner; judging whether a sound value of the sound information is smaller than a preset threshold or not; if yes, determining that the cooling system of the air conditioner fails.

The invention relates to the computer field, and discloses an information recommendation method and electronic equipment, so as to solve the technical problem that the recommendation information generated in the prior art is not accurate enough. The method comprises steps: the use state information of a household appliance is acquired; based on the use state information of the household appliance, whether the household appliance is in a preset use state is judged, wherein when the household appliance is in the preset use state, the user of the electronic equipment is characterized to be in a preset working state; and when the household appliance is in the preset use state, the recommendation information corresponding to the preset working state is generated. Technical effects of generating more accurate recommendation information are achieved.

The invention relates to a method for determining the content of monomer aromatic hydrocarbons in gasoline through gas chromatography to mainly solve problems of large method establishing difficulty and large valve switching system dead volume of present chromatographic methods. The method, which allows an analyte which is the gasoline to be analyzed through a flow switching center cutting chromatographic device, concretely comprises the following steps: injecting the gasoline sample from a chromatographic shunting introduction port (3), pre-separating through a chromatographic column (4), cutting benzene, an internal standard substance and toluene to a chromatographic column (6) through a flow switching center cutting system (10), further separating, and detecting through a hydrogen flame ionization detector (5); and detecting other aromatic hydrocarbon components through allowing them to enter a damping column (2) after they are separated by the chromatographic column (4), wherein the chromatographic column (4) is TCEP[1,2,3-tri(2-cyanethoxy)]propane capillary chromatographic column; and the chromatographic column (6) is a nonpolar chromatographic column. The method well solves the problems through above technical scheme, and can be applied to the industrial production about the chromatographic analysis of gasoline samples.
