1. It is suggested to take the direct bus line: No.49 / No.49 inter district bus / no.520 / high speed rail express (Hexi line) / high speed rail express (Hedong line), etc. the whole journey takes more than 1 hour, passing 23 or 4 stops, and the ticket price is 2 yuan / 5 yuan / 10 yuan, etc.
2. Two consecutive years of physical examination are here, unmarried less physical examination proceres, soon over. They were all female doctors with a very kind attitude. The female nurses were young and timid. The place is not big. It's only on the first floor. There are not many people in a small room for an inspection project. There are big buckets of pure water and disposable cups in the waiting area. Stairs and elevators are available, but one of the elevators only leads to the second floor. If you want to go, you'd better take the east elevator to the third floor. The bathroom is basically clean. There are 3 or 4 people standing at the front desk, and a special mm guide sitting in the hall on the first floor. Generally speaking, it's not bad.
3. There are about tens of billions of brain cells in human beings. Each brain cell has about hundreds of nerves. Each nerve has about hundreds of synapses, and each synapse has hundreds to thousands of proteins. The function of a brain cell is about equivalent to a large computer, and the function of a synapse is about equivalent to a chip of a computer, The human brain is equivalent to hundreds of billions or trillions of chips.
at present, the largest parallel computer of human beings, the white ASCI computer of the United States is only 8000 chips, which is about 100 million times less than the human brain, that is, 8 to 9 orders of magnitude less than the human brain.
the computing power of a computer is generally calculated by how many addition operations can be done in a second, At present, the fastest is the "Earth Simulator" in Japan, with 4 billion times.
if we compare the human brain with a computer, because the human brain is a super huge parallel computing system, all synapses and all proteins on each synapse can move instantaneously at the same time, and the distance between proteins is only a few nanometers, and the current can run hundreds of billions of times a second at this distance, The computing speed of human brain is an order of magnitude that can't be described. About one is followed by 27 zeros to 30 zeros. You know, four billion times is just four followed by 10 zeros, which is about 20 orders of magnitude less.
therefore, if we use computers to simulate the function of human brain, at the speed of current research progress, it will take about one hundred years to realize, The computing speed of a computer doubles every 18 months, which is about 0.57 times every year. It will take more than 100 years to improve by 20 orders of magnitude. I will never see it in my life.
another factor is not considered. Computers have two circuit states, on or off, and there are many kinds of brain cells, nerves, synapses, proteins and amino acids that make up proteins, Exercise is much more complicated than circuit. Therefore, the time for human beings to understand the function of human brain has to be delayed.
human brain is the most delicate intelligent organ in human body. It weighs about 1.3 kg, and its volume is only 1.4 m3. It is composed of more than 10 billion nerve cells. Around each nerve cell, there are 1000-10000 synapses stretching out, These synapses, like circuits, have a "gate" that can pass through or stop the "flow of electrons", so the brain can store 10 trillion bits of information. Such a storage capacity can be comparable to the storage capacity of 10000 computers.
there are two ways of thinking in the human brain: one is formal thinking, which is the performance of the dective ability of the human brain, It has the characteristics of logical sequence: one is fuzzy thinking, which is the performance of human brain's inctive ability, and can carry out comprehensive and overall thinking at the same time. Although there are about 1000 nerve cells dysfunction every hour in human life, and nearly 9 million nerves lose function in a year, even so, the brain can still work normally. The main reason is that, That is, the brain has enough "reserve power". When some nerve cells fail, other "reserve" nerve cells will replace them immediately.
inspired by the functional principle of the human brain, scientists have successfully developed the electronic computer. The electronic computer is one of the most important inventions in the 20th century. It has extraordinary computing power, and the fastest computer in modern times can work in one second, It can complete hundreds of millions of calculations. The speed and reliability of the calculation process are beyond the reach of manual calculation. The computer can also imitate some feeling and thinking functions of human beings, judge and reason according to certain rules, and replace part of human brain work. Because of this, the computer has been highly valued by people, and is called "computer", And it has been widely used in various fields.
modern computers always work according to people's prescribed proceres. In these proceres, people should foresee all possible situations for the computer, and arrange how the computer should respond. Once unexpected situations occur, the computer will be confused and helpless.
the computer is very large, Although it has the same number of components as human brain cells, the volume of each component is 1 cubic centimeter, and the energy consumption is 0.1 watt; When many components are assembled, its volume is already 10000 cubic meters. It is 6 million times the volume of the brain, and the energy required is as high as 1 million kilowatts, which is equivalent to the power generation capacity of a modern large hydropower station.
therefore, although the talent and magic power of the computer are extraordinary, it is far better than people in some aspects, But the human brain is still the most perfect "natural computer" in the world

4. The professional physical examination institutions of Xi'an University include: Pratt & Whitney physical examination, Jiakang physical examination, Kangcheng physical examination, Red Cross physical examination, delip physical examination, etc. among them, Pratt & Whitney is the largest. There are three branches in Economic Development Zone, Jiaotong University south gate, and Laodong South Road. Jiakang is in Laodong South Road, Kangcheng is in Nanmen and Huzhu Road, Red Cross is in Fangxin village, delip is in Wenyi road, Basically, there are more physical examination institutions on Laodong South Road.
5. Okay? dear. The technical level and medical concept of Xi'an Red Cross has reached the international advanced level. So many people go there to see a doctor. I used to have a colleague who looked after it there. With good technology, there are more and more doctors. I suggest you go and have a look
6. oh Not long ago, there was a week before and after!
