    As the car passed by Kangka, He Tao also proposed to visit the new city construction site. Guan Fei did as he wished and drove to the new city on the road between the two mountains.  The tourist bus behind us also followed, instead of going directly along the main road to the military subdivision.  Arriving at the new city construction site, He Tao looked straight ahead. Tens of thousands of people were working on a construction site at the same time. Such a huge scale of construction has been rarely seen in China in the past two years.  He was also amazed by the speed of construction of the new city.  From the report, he knew that the Polytechnic University¡¯s first project in the university town had not yet been completed except for the main part of the teaching building, and that the student dormitories, laboratory buildings, gymnasiums, etc. had been completed.  But the words were always dry. When he saw with his own eyes a large campus covering thousands of acres, the transplanted grasslands, flower beds, artificial lakes, rockeries, pavilions, tennis courts, circular sports fields, and a  The towering student dormitories, libraries, and large indoor gymnasiums that can accommodate thousands of people still showed shocked expressions.  When he looked up at the teaching building, which had been built to eleven floors and was about to be topped out with one more floor, his expression was particularly serious.  It can be said that this is a school that can be opened immediately.  The scale of two thousand acres is limited by the urban terrain, which is much smaller than many domestic universities with tens of thousands of acres.  However, many domestic universities are comprehensive universities. One university contains two comprehensive disciplines, liberal arts and sciences, and is divided into many departments.  The planning drawings designed by Guan Fei, each university is aimed at a clear and specific discipline.  Not counting the School of Economics and Management and the School of Medicine, all universities are purely science and engineering!  After leaving the school, they went to see the construction of residential areas and commercial areas.  He was even more moved when he looked at the whole community, which was full of twelve-story small high-rise buildings, and each building had more than two elevators.  This is considered a high-end residential area. Even provincial and municipal cadres in China still live in government compounds.  Maybe the room area is larger and the living environment is better, but no one can live in an elevator apartment!  When he heard that this was just the first batch of ordinary apartment buildings, and that high-end villas would be built on the bank of the river in the future, he was speechless.  If such conditions are really achieved, it will be no worse than developed countries abroad.  When they passed by a sewer pipe construction site under construction, He Tao was intrigued and went in to take a look.  He found that it was more of an underground tunnel than a sewer.  The sewer, which is three meters wide and two meters high, is buried deep underground, with the top of the tunnel fifteen meters above the ground.  Throughout the tunnel, various pipes of different thicknesses are fixed in an orderly manner.  There are sewage pipes up to half a meter thick, and tap water pipes 20 to 30 centimeters long. There are electrical wire pipes on the left wall, and telephone wires on the right wall.  Every ten meters or so, a support column will be set up in the center of the tunnel.  All lines are concentrated in this passage, making it easy for staff to inspect and repair at any time.  If something goes wrong, it is very easy to repair and replace.  They stopped and walked along the way, getting off the car from time to time to take a closer look. It was not until the afternoon that they arrived at the location of the military subdivision.  This time He Tao had no chance to express his emotion to Guan Fei and the others for their simplicity.  The military division, brigade headquarters, and each company have all moved into new barracks. The valley of about one square kilometer is divided into a regular checkerboard pattern by a group of brand-new buildings.  Dozens of three-story military barracks overlap each other, and each barracks has its own separate courtyard for gathering troops and training.  The barracks are not only a place for soldiers to rest, but also a place for study and entertainment.  In each barracks, there is a large conference room and a small conference room.  There is also an activity room of about 200 square meters, which is divided into a badminton court and an indoor sports ground for volleyball and basketball.  There is an open space next to it, where a table tennis table made by the military division's wood factory is placed.  In the large conference room, he also saw a large rolled-up curtain and projector - it can also be used as a small cinema!  Such comfortable conditions have nothing to do with simplicity. They are simply great. Compared with the best military barracks in the country, they are not worse at all, but even worse!  The soldiers I saw along the way were all in high spirits, and from time to time I heard bursts of laughter coming from the soldiers.  It can be seen from the laughter that the soldiers are very satisfied with the current conditions.  Good housing and living conditions, in turn, promote the soldiers' sense of belonging to this fighting collective.  The momentum of various developments in the military division has given these soldiers full confidence in the future development of the military division, and they are willing to obey the arrangements of their superiors.  Various preferential treatment policies for soldiers in the army, such as retirement skills training, package distribution, etc., have further tied the soldiers' futures closely to the military divisions, whether it is combat courage or?The will and determination have been greatly enhanced.  If people from the capital last time saw the possibility of future development of the military division, then He Tao now, through his observation, this possibility has turned into a real thing.  It is enough to know this.  On this trip, what they, especially the two old professors Zhao Wenliang and Fan Zhe, want to know most is the current technical strength of the military division.  Originally, they thought they wouldn¡¯t be able to see much before each factory was officially opened.  Who knew, they would have made a new discovery before they even arrived at the technical school.  At that time, the car was about to pass through a small valley when it heard a very loud knocking sound coming from inside.  "What is this place? Why is it so noisy?" Seeing the tourist bus stop behind, Guan Fei just got off the backing jeep when he was pulled by Fan Gong and asked.  It happened that a Jiefang truck drove in, and through the open rear panel of the truck, you could see several steel workpieces placed on it.  The surface of the workpiece looked a little black in places, as if it had been burned by fire.  "This has just been heat-treated?" Fan Zhe's eyes were very sharp, and he could tell at a glance that this was a workpiece that had just been heat-treated.  "Yes! This is where we perform stress relief. After the rough-machined workpiece is sent for heat treatment, it will be placed here and then beaten with a vibrating stress hammer for a long time to eliminate the internal stress of the workpiece." There is nothing to hide.  Yes, Guan Fei said openly.  "Use a vibrating hammer to eliminate internal stress!" Fan Zhe's eyes lit up immediately.  Stress is the internal deformation of an object due to its inability to move after being subjected to external forces such as impact and burning.  It¡¯s like when a person is hit, he may shrink into a ball.  Various materials such as steel and wood will also undergo internal changes after being impacted by external forces. The stronger the impact, the greater the change.  And these deformations will gradually stop after a long time, which is called stress relief.  People in ancient times knew that freshly cut wood cannot be used directly because it will become distorted and deformed after it shrinks and dries out.  Therefore, the ancients would leave the cut wood for one or two years to allow the moisture inside to be completely eliminated and the deformation to end before processing it into ship boards, furniture, etc.  The same is true for steel.  When the accuracy requirements are not high in the early days, it is generally only lathe production and other aspects that require stress relief on the steel.  For equipment that has not undergone stress relief, some parts of the equipment may be deformed after stress relief, causing the machine's working efficiency to decrease, wear and tear to increase, seriously reducing the service life of the machine, or even completely scrapping it.  In order to eliminate stress, the traditional method is the aging method, which is the same as processing wood, leaving it on the open ground, exposed to the sun and rain, and letting it sit for a long time to release its internal stress.  This method works well, but it is too time-consuming.  For example, if a machine tool factory wants to manufacture a machine tool, it must smelt the required steel and alloy castings several years ago, and then let them stand to eliminate stress.  After the stress is eliminated, new stress will be generated due to the violent collision of the tool with the material during the initial machining process, so it needs to be rested again.  Each time it is left to rest, it may take several months for a short period of time, or several years for a long period of time.  Therefore, if a machine tool factory receives an order and instead of purchasing the finished product, redesigns the production and does not have suitable stress-relieved parts on hand, it may take five or six years from receiving the order to final production.  It's quite long!  In the event of an emergency, such lengthy stress treatment simply cannot meet market needs.  The development of human science and technology progresses according to needs.  People need to quickly eliminate the internal stress of solid materials to meet flexible production needs, so they began to conduct research in this area.  This research began in the 1960s. Due to slow progress, limited research methods, and long wait for verification results, it took more than ten years to find a relatively reliable method to quickly eliminate stress, which is the vibration method.  Isn¡¯t the stress caused by impact? Then we give it a certain impact at the corresponding position to help it quickly release the stress. This is the research idea of ??the vibration method.  There are studies in this area abroad, and China is naturally following up quickly.  ¡°However, due to the impact of the unrest, limited investment, and low level of automation, domestic research progress has been very slow.  Foreign countries have basically summarized the rules of the vibration method and begun to promote it in some industries. However, domestically, it is still at a low level and cannot be practical.  The aging method and heat treatment method currently used in China are mainly used.  The statute of limitations takes a long time,Needless to say, the heat treatment method is to put the workpiece into a kiln and burn it at an appropriate temperature. It is also a method of fighting fire with fire.  But the heat treatment method is very difficult to eliminate stress in some special positions, and after heat treatment, the workpiece will deform greatly and needs to be processed again.  This processing may produce new stress, so it is a helpless choice with high investment, high energy consumption and not very satisfactory results.  Fan Zhe is a senior engineer at the Mechanical Design Research Institute, and is naturally familiar with the vibration method. When Guan Fei said that the vibration method was used to eliminate stress, his eyes immediately lit up.  ¡°Can I go in and have a look?¡± He asked excitedly, his face shining.  "Of course!" Guan Fei smiled and led the way. Fan Zhe followed impatiently. Zhao Wenliang and others knew nothing about the vibration method, so they just followed and watched the excitement.  Zhao Zhonghua is responsible for civil affairs. After the construction of the new city is completed, he will play the same role as the mayor, so he comes to the technical school more often.  He knew that the heat-treated workpieces were piled up in this valley. He had also seen it. He had also seen the noisy thing and heard someone briefly explain what it was used for.  Just because he was used to it and to avoid the noisy noise, he rarely came here again.  But when he saw Fan Zhe looking like a pervert seeing a beautiful woman, he couldn't help but murmur in his heart: Could it be that that noisy thing is actually a good thing?  He Tao doesn¡¯t understand this either, but he knows how to watch people¡¯s actions. As soon as he saw Fan Zhe¡¯s excited expression, he knew that Guan Fei had something good in his hands.  "Um, what is stress relief?" He was very studious, chasing after Professor Fan Zhe, and asked shamelessly.  After Fan Zhe¡¯s dancing and impassioned explanation, he understood.  Not only did he understand it, but everyone else understood it too.  He Tao's face turned red and he felt like the blood on his body was rising.  Relieve stress!  This technology is so important and critical!  If we have this technology, we can mass-produce high-precision lathes, equipment, tank engines, fighter planes, warships according to needs in China "This vibrationvibration stress relief method, is it your own technology?" He immediately said  He passed Fan Zhe, grabbed Guan Fei and asked.  "It's intelligence" "Fuck your intelligence dealer!" Before Guan Fei could finish his words, He Tao blocked him back angrily, "I don't care if you bought it from an intelligence dealer, you have this technology.  Yes? Not completely? How long does it take to eliminate the internal stress of a component? "Okay, I'll just pick it up on the road next time!"  Guan Fei regretted the disappearance of a good excuse, shook his head and explained to him: "Your question is unscientific! The time required to eliminate the internal stress of a component is related to its size, structure, and processing method. Large equipment  It takes a long time to eliminate the stress of parts. At the same time, the processing methods are different, and the internal stress changes of the materials are also different. If you ask this, I can't answer you. I can only roughly tell you how to eliminate the stress of a lathe bed.  , It will take a few days" "I want this technology!" He Tao said decisively without waiting for him to finish.  ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????Compared to the statute of limitations law, which can often take several years, this little time is like nothing.  With such good technology, you would be a fool not to use it!  "I can sell domestically made sub-vibrators for only 6,000 yuan each! I will give you as much as you want!" Guan Fei was unambiguous and immediately agreed.  Nonsense, even if Fan Zhe didn't find this thing, he would take the initiative to take them to see it.  The circuit structure of this sub-vibrator is very simple, and the processing of the vibrating hammer is not difficult.  The quoted price is 6,000 yuan, but the actual manufacturing cost is only 2,000 yuan!  This thing costs tens of thousands of dollars each abroad. The key to its value lies in the setting of the vibration frequency wave. This is high technology!  In order to find a suitable vibration frequency wave, foreign countries spent more than twenty years constantly improving and revising it. It was not until the 1980s that it was finally finalized and promoted on a large scale.  By the 1990s, except for a few manufacturing companies with high-precision requirements, almost all factories used sub-vibrators to eliminate internal stress in workpieces.  China only began to gradually learn this technology in the 1990s.  But at that time, there was already better stress relief technology, so this thing seemed useless. It was sold publicly on the Internet and there were very few buyers.  But in this era, it is really a big killer!  Making money is not about selling good things at high prices, but more importantly, choosing the right time.  What people are pursuing is the popular technology that makes money!
