The invention discloses a duplication elimination method based on search results of a metasearch engine. The duplication elimination method based on the search results of the metasearch engine is provided to solve the problems that in the prior art, duplication elimination cannot be carried out on the same web pages of URLs with different formats and redirected web pages, and sentences and articles cannot be represented fully according to information around punctuation marks, positions of the punctuation marks and fuzzy matching of word frequencies. The method comprises following steps such as 1, judging whether there are duplicated web pages or not according to URL addresses; 2, computing the title similarity of the two web pages and the abstract similarity of the two web pages; 3, computing the similarity of the web pages according to the title similarity and the abstract similarity; and 4, determining that the two web pages are duplicated if a similarity value Sim (A, B) is more than a threshold. The method can be applied to the field of duplication elimination based on the search results of the metasearch engine.

The invention discloses a battery state of charge SOC correction method and device and an electric automobile, and belongs to the technical field of electronics. The method comprises the steps that the initial state of charge SOC and the first temperature value of a battery pack system at the ith moment are acquired, wherein i>0; the actual SOC of the battery pack system is determined according to the first temperature value; the theoretical SOC of the ith moment is calculated according to the initial SOC and the first temperature value through an ampere-hour integral method; and the theoretical SOC is corrected according to the difference value between the theoretical SOC and the actual SOC so that the corrected SOC corresponding to the ith moment is obtained. The problem of inaccuracy of the calculated SOC caused by the fact that the calculated theoretical SOC is directly used as the real SOC of the battery pack system when the SOC is calculated by a BMS according to the ampere-hour integral method can be solved so that the accuracy of the SOC obtained by the BMS can be enhanced.

The invention discloses a channel quality information computation method, device and system, and belongs to the field of the communication. The method comprises the following steps: a terminal receives a downlink configuration instruction sent by access network equipment; the terminal measures a reference signal source indicated by the downlink configuration instruction to obtain first channel quality information, and sends the first channel quality information to the access network equipment; the terminal sends an SRS to the access network equipment; and the access network equipment computessecond channel quality information according to the first channel quality information and the SRS. Since the first channel quality information can more accurately represent the interference situationof a downlink channel, the problem that the channel quality information of the downlink channel, obtained through the eNB computation is not accurate enough in the prior art is solved; and an effect that the second channel quality information computed by the access network equipment can accurately represent the channel quality of the downlink channel is achieved.

The invention provides a POI coding method, belongs to the technical field of computers, and aims at solving the problem that recommended POIs are not correct enough when POI recommendation is carriedout on the basis of POI coding as the POI coding methods in the prior art do not consider association between the POIs during the coding. The method comprises the following steps of: obtaining a POIsequence of a user operation; training a POI coding model through a deep learning-based neural network architecture according to the POI sequence; and determining a code of each POI in the POI sequence according to a POI coding vector sequence corresponding to the POI coding model. According to the method, POI feature extraction is carried out through the POI sequence generated on the basis of theuser operation, and the POIs are coded on the basis of the extracted features, so that associativity of the POIs is hidden in the POI codes, and then the correctness of carrying out POI recommendation on the basis of the POI codes is further enhanced.

The invention relates to a triaxial planeness detection system and a triaxial planeness detection method. The system comprises four parts including a basic component, a triaxial sliding mechanism, a workpiece locating platform and a laser measurement component. The triaxial sliding mechanism comprises a cross-shaped sliding table and a vertical sliding table, and the cross-shaped sliding table drives a detected workpiece to move in a horizontal range and works in cooperation with a laser measurement instrument. A measurement mode in which the workpiece moves and the laser measurement instrument is stationary is used, thus, accuracy of a measurement result is improved, and a problem that the measurement is not accurate enough when the laser measurement instrument moves and even micro vibration can cause large deviation of the measurement result is solved. The laser measurement component comprises three groups of the laser measurement instruments of which laser emitting extension lines mutually form a 90-degree included angle. By coordinated cooperation of the triaxial sliding mechanism and the laser measurement instruments, the system provided by the invention can complete measurement of side face and upper surface planeness of the measured workpiece in one work procedure, and thus, measurement efficiency is improved.

The invention relates to a laser reception principle based electronic height instrument. The laser reception principle based electronic height instrument has much limitation on its application due to the defects that the instrument is easily disturbed externally, inaccurate and the like. The laser reception principle based electronic height instrument comprises laser emission heads, laser reception heads, a main circuit board and support rods. The support rods are used for height adjustment of the height instrument. The laser emission heads are connected with a driving board. The laser reception heads are connected with the main circuit board. According to the height instrument, touch height is detected through vertical laser arrays; when lasers at a certain height are blocked off, the laser reception heads at the corresponding height do not receive correlation laser signals, and thus, the highest touch height of a testee can be judged. By the laser reception principle based electronic height instrument, the problems of low sensitiveness, low accuracy and incapability of moving of existing height instruments are solved effectively.
