Tencent's search engine is soso

development history of soso:

1. it was officially released and put into operation in March 2006

3. on September 3, 2009, the words "the following results are provided by Google" have been removed from the soso search results page, and the search engine technology developed independently has been used instead

5. in 2013, the word "Tencent effect promotion" has appeared on the soso search results page, and it is stepping into commercialization

< / OL >




misunderstanding of Tencent search engine: Tencent vigorously promotes Sogou, many people mistakenly believe that Sogou belongs to Tencent, but it is not

Sogou search engine is the third generation of interactive search engine strongly built by Sohu company. On September 16, 2013, Tencent injected US $448 million into Sogou and merged its Sogou business and other related assets into Sogou. After the transaction, Tencent immediately acquired 36.5% shares of Sogou after full dilution, and the shareholding ratio of Tencent will increase to about 40% in the near future. This makes Tencent have a higher interest and voice in Sogou, and then use its own channels to promote it

3. This year's Chinese college entrance examination (Forum) in Sichuan Province is entitled "familiar", but one candidate wrote a composition in ancient Chinese characters that most people are not familiar with. On the evening of the 17th, a post of "oracle bone inscriptions in Sichuan" appeared on a website, which made netizens marvel. At 8:36 p.m. on the 17th, there was a post on the website of the forum "Guoxue Shudian", which was named "dzjimagine", like a teacher reading papers on the spot, The Post said that on the same day in the language group found "the most powerful gag since marking" -- a composition "familiar" written in ancient Chinese“ "Dzjimagine" said that the teacher who found the composition was the composition marking teacher of Chinese group 1, who then reported to the leader of the marking group; Because the college entrance examination does not prohibit writing in ancient Chinese characters, the leader of the marking group only reports to the language supervision group; The first reaction of the quality inspection team was still at a loss“ As it is forbidden to take photos and take relevant materials out of the marking room for the college entrance examination, I was unable to take photos of the composition at that time (it is estimated that some teachers of the composition group have taken photos quietly). After a rough inspection, this composition mainly uses oracle bone inscriptions, bronze inscriptions, seal script and other ancient characters. The writing is very neat and standard. " The netizen also said that this incident immediately caused a big shock in the Chinese marking group. After the marking work was finished at about 6 p.m., a teacher asked the Chinese quality inspection group about the score of the composition. The reply of the quality inspection group was that they had contacted an ancient character expert from Sichuan University and asked the expert to translate the composition into simplified Chinese as soon as possible, Then evaluate the level of composition. The teacher said that it was true. The reporter noticed that many netizens followed the post within an hour. In these posts, the reporter found that there are generally two views. One is that the examinee is "too good, talent", the other is that "the examinee should play his talent in the art examination room". Is there such a composition? The reporter inquired three teachers in a row and said, "I heard everyone talking about it, but I haven't seen the test paper and I don't know what they wrote. We have regulations that we can't disclose information to the outside world. ". However, a teacher in the Chinese language group revealed that this was absolutely true, because a friend of his had seen the composition with his own eyes. A friend told the marking teacher that the composition was almost full of composition area, about 800 words, very neat“ My friend knows a little bit about this. At first glance, he knows it's ancient characters like oracle bone inscriptions, but he can't understand the exact meaning. " However, the reporter respectively called a number of experts and professors who studied ancient Chinese characters and said that "they have not heard of this and have not been invited.". On the evening of the 19th, Li Cheng, the leader of the Chinese marking group and the dean of the College of Arts of Sichuan Normal University, was contacted by the reporter. He just said "I don't know about this" and hung up. Zhou, director of Sichuan Provincial College of admissions and examination, said in an interview with TV reporters: "you media don't need to know about this. If there is such a thing, it will be reported to the media if necessary. ". He Shanqing, a professor in the History Department of Sichuan University and an expert on ancient Chinese characters, said that if a student really wrote an 800 character article in ancient Chinese characters, he thought it was amazing: "there are not as many ancient Chinese characters as modern Chinese characters, which is very limited, but ancient Chinese characters such as oracle bone inscriptions can still write articles. I have only seen ancient Chinese writings written in oracle bone inscriptions, with a maximum of 400 words; Generally speaking, it takes at least a month to write an 800 word article in ancient Chinese. " He Shanqing made three guesses to the reporter: first, the student was very interested in ancient Chinese characters, and had prepared before the exam, so he was able to write a composition ring the exam; Second, candidates have a certain understanding of the ancient characters, using some radicals to piece together some ancient characters, but the article is not formed; Third, the examinee does not understand the ancient characters, is graffiti, but looks like ancient characters. Hu Guangwei, a sociologist at the Sichuan Academy of Social Sciences, said that if it really exists, it just shows the remarkable characteristics of the "post-90s": they like to show themselves and don't think too much about it; However, if the performance is a little excessive, there is a suspicion of mischief. According to experts in Cheng Evening News, it is not advisable to write college entrance examination compositions in ancient Chinese. Some teachers suggest that college entrance examination compositions should be written in simplified Chinese. In recent days, the news that some candidates write in Oracle Bone Inscriptions in college entrance examination compositions has attracted much attention. The reporter confirmed from some Chinese marking teachers yesterday (21st): at the summary meeting of the marking group, the leader of the marking group reported the scoring of the composition for the college entrance examination. Experts found that there were oracle bone inscriptions, bronze inscriptions and small seal characters in the composition. Because of the wrong topic, the score was low. In addition, because of this "composition of college entrance examination in ancient Chinese", it also leads to another question: whether the composition of college entrance examination can use ancient Chinese characters, and whether "simplified Chinese characters must be used" should be added in the marking rules of college entrance examination. Marking teacher: the score of writing biased questions is low. At present, the college entrance examination papers have entered the final stage of unification and division. The teachers who have been dismissed and returned home are still impressed by the composition. A marking teacher in the central city of Cheng told reporters that at the summing up meeting of the marking group, the leader of the marking group reported the scoring of the composition for the college entrance examination“ All the experts of the expert committee have read it. After translation, they find that although the title of this composition is familiar, the content is far away from the topic. " In the end, the scores given by experts are not high, "only a few points". Another marking teacher also confirmed: "it was said at the meeting, but it was off topic, and the score was low. However, it is not known how many chapters have not been notified, and what the content of the composition is According to this marking teacher, he was in the marking group where he found "ancient writing composition". Later, the marking group spent a lot of effort to find some experts to translate, and found that there were oracle bone inscriptions, bronze inscriptions, and Xiaozhuan. Later, a marking teacher in the group who read the translated article said that the composition was "wrong after the full text", which made people unable to understand“ The key to the composition of the college entrance examination is to examine the students' language organization ability, not the philology. The judging standard still depends on the structure and expressiveness of the article itself. " A composition marking teacher said that although he did not read the translated text of the composition, but from the comments given by the marking group, it is feasible, "so should composition marking.". In this regard, Li Cheng, the leader of the Chinese marking group, refused to be interviewed. But I don't deny that the score of this composition is not high“ There are a set of strict rules for composition in college entrance examination. Once a standard is set, no dispute or amendment is allowed. " Expert on ancient Chinese characters: it takes one or two months to write two or three hundred character articles on oracle bone inscriptions. The reporter then interviewed he Gu, a professor of the school of history and culture of Sichuan University and a member of the Chinese character society. According to Professor He, at present, there are not many experts studying oracle bone inscriptions in Sichuan, most of them are concentrated in the ancient Chinese language research room of Sichuan University. He is skeptical that some candidates use oracle bone inscriptions to write college entrance examination compositions“ For a person who has studied oracle bone inscriptions for decades, it takes at least one to two months to write two or three hundred character articles in oracle bone inscriptions. It's incredible that a high school student can have such a level. " Professor he said that because there are only more than 1000 characters in oracle bone inscriptions at present, and many characters in modern Chinese can't find corresponding characters in oracle bone inscriptions. Take the title of the composition "familiar" as an example, "familiar" can be reluctantly replaced by "who", but "Xi" is not in oracle bone inscriptions. It is almost impossible to express modern language in oracle bone inscriptions, especially in such a short time. For this reason, he speculated that only a few words in this composition may be written in oracle bone inscriptions, and other words may be written in other ancient Chinese characters“ Or, before the examination, I recorded some ancient Chinese characters, and then casually put them on Professor he thinks that it takes much more time to write ancient characters than simplified characters. Professor he said: "as there is not much demand for the application of ancient Chinese characters, there are fewer and fewer students studying ancient Chinese characters. This student may be a good material for learning ancient Chinese characters and suitable for research. " Chinese teacher: writing a composition in simplified Chinese should be included in the scoring standard. For this composition, there is an exclamation on the Internet. Many netizens think this candidate is very talented“ Knowing so many ancient Chinese characters has already reached the graate level. " But more high school and College Chinese teachers hold a negative attitude. A Chinese teacher in Cheng No.7 Middle School said that there is no rule that "simplified Chinese characters must be used" in the college entrance examination marking rules, but the conventional font is simplified Chinese characters. Simplified characters are also used in any formal documents, circulars and publications of the state“ Composition, the most important thing is to see the writing skills, want to use this way (ancient writing) for their own more points, it is very difficult“ For the first time in many years. This is also a signal. Maybe such a rule should be added to the college entrance examination marking rules. " This teacher thinks that after the emergence of this ancient writing, whether there will be candidates writing in "Martian" and "foreign language" in the future, if the marking teacher has to find an expert to translate, then the marking cost is too high. A Chinese teacher in Shishi middle school also suggested that "simplified Chinese characters must be used" should be added to the scoring rules of the college entrance examination. In this way, it also makes teachers more instructive in the ordinary teaching, and more emphasis on students' standardized writing“ It's good to give full play to these specialties after entering the University. It's not advisable when the college entrance examination is so serious. " A professor from the school of literature and journalism of Sichuan University told reporters that at present, the college entrance examination rules all over the country do not explicitly require the writing of simplified Chinese characters. This really let the examinee exploit the loophole. In previous years, some candidates wrote a lot of English in their compositions, but they didn't get good marks either, because this overturned the purity of Chinese characters“ It's OK to quote, but it's not right to use these words instead of simplified characters. After all, writing is a show of pure literature. Those candidates who try to get high marks by writing should be given zero points. " As for the suggestions of these teachers, the relevant person in charge of the provincial ecation and examination institute said that the marking work of the college entrance examination has been completed and has entered the final stage of unification and division. As for whether it will join this part next year, it will be announced to the society in the college entrance examination regulations next year after the consultation of the relevant departments“ Recently, the news that college entrance examination composition is written in ancient characters is spreading rapidly on the Internet, which has become the focus of social attention. Netizens call this composition "the most excellent composition for college entrance examination" this year. The writer has been given a name with the characteristics of post-90s generation - "master of ancient Chinese characters". Attachment: Ancient Chinese composition copied by Xiao Huang after college entrance examination Author: Ancient Chinese composition copied by Xiao Huang after college entrance examination (Page 1) teacher Pu provides composition content: familiar with (teacher Pu interprets it according to the version copied by Xiao Huang, and the mistakes in the text have not been modified) Dayan lost his way in the process of learning to fly because he was familiar with it

If not maintained for a long time, the chain will not bite well and shorten the service life of the machine. In fact, the maintenance is relatively simple, you can use hotolube "tiger head" brand hinge lubricant coating maintenance, high temperature resistance, good rability, can greatly extend the service life of the chain. The machine runs smoothly.

9. The cause analysis and solutions of the top ten common faults of the screw feeder, Gongyi Yili answers for you:
1. Screw feeder blocking:
1. Reasonably select the technical parameters of the screw feeder, such as the speed of the slow screw conveyor should not be too large
2. Strictly carry out the operation proceres to achieve no-load start-up and no-load stop; Ensure continuous and uniform feeding
3. Increase the discharge port or lengthen the end of the chute to solve the problem of poor discharge or too late discharge. At the same time, a small section of counter rotating blade can be installed at the end of the discharge chute to prevent material blocking at the end
4. The materials entering the screw feeder should be cleaned to prevent the blockage caused by large impurities or fibrous impurities
5. Rece the transverse dimension of the middle suspension bearing as much as possible to rece the possibility of blocking when the material passes through the middle bearing
6. Install bin level device and blockage sensor to realize automatic control and alarm
7. An anti blocking valve is set on the cover plate of discharge end. In case of blockage, e to material accumulation, open the anti blocking door and cut off the power through the travel switch< (2) the drive motor of the screw feeder is burnt out:
1. There are hard blocks or small iron blocks mixed in the materials transported by the screw feeder, the cutter is stuck, the current increases sharply, and the motor is burnt out. The treatment method is to prevent small iron blocks from entering and keep a certain gap between the cutter and the casing
2. If the incoming material is too large and the motor is overloaded, it will burn out e to heating. The treatment method is to balance the feeding and send out the material before shutdown< (3) the shell of the screw feeder shakes:
1. When the screw feeder is installed, the center line of each screw section is not concentric. When the screw feeder is running, the shell shakes by rubbing the shell eccentrically. The treatment method is to re install and align the center line< (4) the temperature rise of the suspension bearing of the screw feeder is too high:
1. The position of the suspension bearing is improperly installed, and the treatment method is to adjust the position of the suspension bearing
2. Abnormal friction occurs when large hard objects are mixed into the machine. The treatment method is to clean up the foreign matters and run the machine until it is normal< (5) overflow of screw feeder:
1. Due to the high moisture content of materials, the materials are concentrated on the bearing of screw crane and graally thickened to make the incoming materials difficult to pass through. The treatment method is to strengthen the drying of raw materials
2. The impurities in the material block the screw crane bearing, and the treatment method is to stop the machine and remove the impurities
3. The failure of transmission device is not found in time. The treatment method is to stop the machine and repair the transmission device< (6) looseness, drop and fracture of screw shaft connecting bolt:
1. Uneven stress ring operation time causes looseness, drop or impact fracture of bolt, and the treatment method is to improve the strength of bolt connection< (7) tearing of spiral blade of screw feeder:
1. Foreign matters in raw materials may cause damage to spiral blade, and in serious cases, the welding joint between spiral blade and spiral shaft will be desoldered, resulting in tearing of spiral blade. The quality and strength of spare parts should be improved for the damage of spiral blade. The consistency of blade should be ensured ring the proction of spare parts, and the weld should be dense and reliable, so as to avoid slag inclusion, porosity and other defects, Ensure the welding quality and improve the strength of screw shaft and transmission shaft< (8) torsional crack of flange welding joint of screw feeder:
1. Due to the abnormal torque, the welding failure of connecting flange, the treatment method is to ensure the installation accuracy of the equipment, whether it is flange connection or spline connection, the installation position accuracy of the screw body should be ensured. After installation, wiring debugging should be carried out to determine whether the screw steering and sound are abnormal. After the test run, check the temperature rise of motor, recer and bearing. After everything is normal, start the manual screw bin gate to graally feed. After debugging, the screw runs smoothly< (9) screw shaft cracks:
1. Due to long-term operation wear, torsional strength is reced and cracks and cracks are formed. The treatment method is to strengthen equipment maintenance, prevent screw shaft from wear and fracture, strictly control the quality of raw materials and prevent foreign matters from entering the conveyor; Carry out lubrication maintenance for lubrication parts regularly; Strengthen the spot inspection and maintenance of driving device; The quality of the spiral blade is detected regularly. When the spiral blade is worn abnormally, the spiral shaft is deformed, and the strength is reced, it should be replaced in time, and the causes should be analyzed to prevent the trouble; If the coupling is loose, fasten it in time; In case of heating, noise and other abnormal phenomena ring equipment operation, timely check, clean up foreign matters and repair screw or chute< (10) screw shaft input shaft section fracture:
e to screw feeder installation, screw shaft coaxiality out of tolerance or low safety factor ring shaft selection, equipment transformation and maintenance shall be carried out according to proction needs. When the process changes and exceeds the scope of equipment performance, continuous operation will cause rapid damage to the equipment, even fail to meet the proction process requirements and affect normal proction. It is necessary to overhaul and replace parts according to the actual situation and site conditions, such as changing the drive system, changing the transmission ratio, improving the material performance of spare parts or changing the size, until replacing the equipment.
