Chapter 151 Model Heart

In order to complete their studies as soon as possible, Ou Zhou and Jiang Yang worked hard during the vacation, studying day and night. Compared to other students who are relaxed and leisurely, they are a pair of typical ascetics.

People who don't know always think that they are two poor students who are diligently pursuing.However, they are young talents worth tens of billions.

The biggest gap between postgraduate research and doctoral research lies in their scientific research capabilities, which include finding and discovering topics, carefully polishing the topics, and evaluating the use scenarios and thinking skills of the topics, which is what people usually call innovation.

The purpose of the master's degree is to cultivate the master's level of research on a certain specialty, while the doctoral degree is to conduct careful and in-depth research on a certain field of this profession.

Therefore, the requirements for a doctorate are higher, and the requirements for the quality and ability of students are much higher than those for a master's degree.Therefore, it is much more difficult for doctoral students to graduate than for graduate students to graduate.

Usually, the schooling period for doctoral students is three to six years, and the normal time also takes four years, which is equivalent to the time for an undergraduate degree.

In view of the super learning ability and huge dedication of the two seniors, they only need two months to complete the one-year study of ordinary people. Strong thinking and unusual analytical skills are also crucial.

What Boyan needs most is to find the professional ability to analyze and solve problems, and to elaborate logically and systematically to form written documents.

The two brothers and sisters had a lot of fun. Apart from eating and sleeping, they spent a lot of time on a series of academic research and various experiments every day.

The two took artificial intelligence heart research as a proposition, and carefully developed and excavated the elements.

In the human body, the most mysterious thing is the wonderful working principle of the meridians, brain, and heart.

With the current scientific community, it is still impossible to systematically decipher the mysteries of these three parts.

There is a powerful unknown power hidden in the latitude and longitude veins, which has been witnessed since ancient times.

The overlord of Western Chu is powerful enough to pull up mountains, and he is powerful enough to pull up mountains. What kind of strength is this?Li Yuanba, a hero of the Sui and Tang dynasties, had a pair of golden hammers for beating drums and urns weighing [-] catties, and they beat the [-]th anti-kings on their backs.Li Cunxiao, a famous general of the Five Dynasties and Ten Kingdoms, is said to be able to separate two bullfighting bulls.

Although these are the descriptions of historical novels, there are always wonders in the vast world, and the stories of the characters in the novels are mostly derived from the little things in life.

And there are countless descriptions about super brains.There are many figures in history who have the ability of photographic memory.

Zhang Heng, an astronomer in the Eastern Han Dynasty, ranked first. There is such a description in "The Biography of Zhang Heng in the Book of the Later Han Dynasty": Although I can read it at a glance, I can still recognize it. This memory ability shows that it is very good.

Ranked second is Zhang Song from the Three Kingdoms period. After reading Meng De's new book in front of Yang Xiu, he could recite it word for word. Cao Cao even burned his new work because of this, thinking that what he wrote was nothing more than in this way.In fact, it was Zhang Song who used his extraordinary memory ability to make Cao Cao mistakenly believe that his works were as Zhang Song said, and three-year-old children in Sichuan could also recite them. The implication was plagiarism.

The third place on the list: Fei Yi, one of the four heroes of the Shu Han Dynasty.This person is Liu Bei's counselor, from the official to the military adviser, and the general.He is very outstanding, he is shrewd in handling affairs, has extraordinary knowledge, usually reviews official documents, and at a glance, he can already understand the main meaning of them, his speed is several times faster than ordinary people, and he has the ability of photographic memory.Moreover, this person also likes to play and do things at the same time, and his business has not been delayed at all.

Dong Yun, a famous Confucian in the late Han Dynasty, sighed after seeing it and said: "This man's excellence is beyond my reach."

As for the super heart, there are few descriptions in ancient times, but in modern times, it mostly appears among the big heart players in the NBA.

Presumably many fans will think of several names in their minds in the first time.However, a thousand readers have a thousand Hamlets, and a thousand fans may have a thousand answers.

The first is Fisher. Like Kobe, he is also a rookie in 96. He spent most of his career with the Lakers and won five championship titles with the Lakers. He is a veritable big-hearted player.

The second is Gilbert Arenas. Arenas is a player who has left a deep mark in the league. He has an extraordinary sense of smell and a big heart for the game.

The third is Livingston. Livingston's average data per game may not be so brilliant, but he has rich experience on the court, and his heart is also recognized as strong among fans.

Brothers Ou Zhou and Jiang Yang's research object is the artificial intelligence heart, so it is necessary to work hard on the heart.

In the laboratory, what they dissect the most is the heart.Now they are ten times more familiar with the body and structure of the heart than their palm prints.

The heart is the engine of the animal world. From a physical point of view, the heart is a continuous pump that pumps blood from the veins back to the heart 24 hours a day, and outputs the oxygenated blood from the lungs to the whole body.

These tasks are accomplished by the regular contraction and relaxation of the myocardium.

Therefore, once the myocardium is damaged, the function of the pump will be affected, and in severe cases, it will lead to sudden stop and death of the body.

The most frightening thing about coronary heart disease is that it suddenly stops the heart and causes the death of the body.

Therefore, the heart is the organ that dominates life.

The heart is divided into left heart and right heart.The left heart and right heart are divided into left atrium, left ventricle, right atrium, and right ventricle.

The mitral valve separates the left atrium from the left ventricle, and the tricuspid valve separates the right atrium from the right ventricle.

The left ventricle is connected to the aorta and separated by the aortic valve.The right ventricle is connected to the pulmonary artery and separated by the pulmonary valve.

Venous blood is pumped back through the right atrium and compressed to the right ventricle. The right ventricle contracts to pump blood into the pulmonary artery. In the lungs, blood is fully oxygenated and pumped back to the left atrium, pressed into the left ventricle, and finally the left ventricle contracts to pump blood into the lungs. The aorta, the coronary arteries, cerebral arteries, hepatic arteries, and renal arteries that are delivered to the heart, supply nutrients and oxygen to the whole body.

Problems with any of these pathways can lead to heart disease, leading to heart failure.

Although the heart is full of blood, its own blood supply and oxygen supply are carried out through the coronary arteries from the root of the aorta.

The coronary artery is left and right, and the left coronary artery is divided into two branches. It emanates from the root of the aorta, wraps the entire heart from top to bottom, and is worn on the heart like a hat, so it is called coronary artery.

Abnormalities in the structure of the heart are called congenital heart disease (congenital heart disease) if present at birth, and acquired heart disease (post-onset heart disease) if acquired after birth.

In addition, the engine of the heart needs to generate electricity to drive it, and it has a regular and tight circuit structure to make the heart beat regularly. If there is a problem with this part, it is called arrhythmia.

The common electrocardiogram refers to the heart rate.

In order to better grasp the research and development of artificial intelligence heart.

Brothers Ou Zhou and Jiang Yang made multiple heart models to verify their academic ability and lay a solid foundation for the future development of smart hearts.

The first is the active heart model, which uses a series of cams, small electric pearl light circuit motors, and transformers to control the beating of the rubber heart.

Through repeated verification, it is found that the mechanical structure of the model is complex, and the rubber is easy to age, and the use effect is not ideal.

After careful research and improvement, Ou Zhou and Jiang Yang developed a new "heart and blood circulation simulator".

But this kind of simulator is relatively expensive, and the cost of each piece is more than one million.

Fortunately, they are not short of money. In order to achieve the goal of eliminating evil and promoting good, so that human beings can move towards a harmonious society as soon as possible, money is nothing to them.

Later, the two brothers proposed the basic idea of ​​a new model, which is to make the movable parts of the heart, the atria, ventricles, and valves, into a number of movable blocks, with fulcrums and pins on the blocks, and design a number of curves according to the law of blood circulation. Slots and curves can be closed or non-closed slot plates to control the trajectory of the pin.

When the grooved plate rotates, the moving track of each piece along with the pin in the curved groove simulates the heart activity process.

For blood circulation, several slots or arrows are opened on the blood vessels of the panel, the head, and the body, and the patterns attached to the panel are displayed in the grooves, and the patterns are rotated to vividly display the flow of blood.

According to the "China Cardiovascular Disease Report 2016", at present, cardiovascular disease deaths account for the first cause of death among urban and rural residents.Almost close to the 50.00% ratio.

The prevalence of risk factors for cardiovascular disease is evident, leading to an increase in the incidence of cardiovascular disease.The number of patients with cardiovascular disease will continue to increase rapidly in the next 10 years.

In view of this, the future market application and prospects of artificial intelligence heart are difficult to estimate.

Later, Ou Zhou and Jiang Yang used a single-chip microcomputer, pressure sensor, liquid pump and vibration device to glue and assemble another heart model.

The original heart model includes the original chest model, the original blood vessel model, and the original organ model in the chest cavity.

The original organ models in the thoracic cavity include the original heart body model and the original lung model, and the production method of the original model adopts 3D printing technology.

The original blood vessel models include the original aorta model, the original pulmonary artery model, the original coronary artery model, the original superior vena cava model, the original inferior vena cava model and the original pulmonary vein model.

The single-chip microcomputer embedded in the model is connected to the external single-chip microcomputer, and the heartbeat frequency of the sphygmomanometer is changed by controlling the liquid pump and the vibration device, so as to realize the periodic output of blood and the beating of the heart, making the model more realistic.

And through 3D printing rapid prototyping technology, finished products can be produced quickly and remotely.

If the silicone rubber casting method is used, the molding efficiency is high, the production time is short, the molding reproducibility and mold release performance of the mold are good, and dehydration will not occur.

Finally, the electroformed nickel shell-ceramic backing mold is used to ensure the strength and wear resistance of the heart model.

The heart mold is made by the silicone rubber pouring method, the material used is low in price, the forming efficiency is high, and the production time is short.

It can be cured at room temperature, and the silicone rubber has good molding reproducibility and mold release performance; the mold made will not shrink.

When the curing temperature of silicone is 40°C, the curing effect is the best, and the obtained heart model is most similar to the real heart and its surrounding structures.

The liquid pump is placed in the blood vessel model to control the periodic changes in the pressure and flow of blood flow. The vibrating eccentric wheel is placed in the heart body model to control the heart to vibrate at a certain rhythm. The single-chip microcomputer in the chest cavity model is connected to an external single-chip microcomputer.

The external single-chip microcomputer is connected with a display screen, and the vibration frequency and amplitude, blood pressure and blood flow rhythm in the heart are displayed on the display screen through the single-chip microcomputer.

The brothers Ou Zhou and Jiang Yang, who forgot to eat and sleep, worked tirelessly, and made rapid progress in their studies, were highly praised by the two mentors.

They unreservedly imparted all the knowledge they had mastered, wishing to pass through a pipe and directly transfer the knowledge to the minds of the two disciples.

It was in such a highly harmonious state of teacher-student relationship that the knowledge of the two teachers and brothers rose rapidly like a rocket.
