In the early morning of the next day, Li Tieguo and a few other elite backbone engineers took a plane to Africa, which actually went to the non-domain to support the Chinese railway engineers, thousands of people a year, and most of these people were engineers distributed in various sections, and after arriving in the non-domain, they were going to work in specific railway factories according to the plan.

So Li Tieguo's people are not so rare, it will be very normal there, very ordinary, and a day later, they landed, and they were greeted at the non-domain airport by the leaders and employees of the non-regional railway department, and then there were several Chinese translators living in the non-regional area.

Then Li Tieguo didn't talk much in the middle of the pedestrians, just followed, and after getting in the car until he arrived at the specific location, Li Tieguo was arranged to live in a spacious bungalow, the environment is not difficult, but it is not superior.

Later, when it was evening, the leader of the non-domain took the translator and Li Tieguo and the group to briefly talk about their thoughts, that the non-domain had just introduced the diesel locomotive, and wanted Li Tieguo to help train a group of train drivers with internal combustion engines, after all, driving a train is not a trivial matter, the technical requirements are very high, and it is more difficult than the previous driving of steam locomotives.

Another one also hopes to help optimize diesel engine technology, such as internal combustion engine maintenance technology, braking system, instrument system, oil supply system, flaw detection system, etc., a lot, in short, to put it bluntly, I want to learn experience and technology,

After Li Tieguo and his entourage heard this, they also had a bottom in their hearts, most of them were locomotive workers, and then they either studied by themselves or organized training, their own knowledge and skills are excellent, and they have a lot of experience in practice and work, so Li Tieguo and these people held a meeting that night to talk about it.

Wait until the next morning, they followed to the scene, that is, in a large factory, and then according to Li Tieguo's discussion, Li Tieguo was responsible for teaching the braking system in maintenance, don't look at such a system,

But in fact, it is the top priority, the braking system is the core of the train, the speed control and speed of the train and the need for braking system, think about it, if a train can not brake after starting, then the consequences will be how terrible, unlike some failures of other systems, you can rest and check after stopping, and then the big deal is waiting for rescue, and the braking system has a big problem, even the car can not be stopped, how to overhaul it?

Ten years ago, steam locomotives used ET6 braking systems, which were actually similar in principle to now, relying on wind and air pressure to push the parking plate and create enough friction to make the wheels gradually slow down.

But don't look at this is very simple, the knowledge and requirements contained in it are very high, trains and cars are different, cars have tires, the anti-friction loss of tires is much stronger than steel wheels, and trains can only run with steel wheels, so the requirements for friction are very high, the friction is too large, the steel wheel rubs out sparks, produces a gap, the train body violently shakes, the train is originally a large tonnage, and the violent vibration will directly cause the train to break or even collapse, but the friction is too small, the train can not stop for several kilometers, and it has lost its meaning. Therefore, at that time, the prescribed pressure in our country was 500 to 600, and the braking coefficient was 140 to 170, but this was under the assumption that there was no environmental impact outdoors, the braking coefficient would be reduced on rainy days, and the braking coefficient would be enhanced on the leaves on the train.

This led to the sand throwing machine, the use of sand to increase the friction coefficient of the train and so on, and in addition to the braking system there are a lot of sayings, to really talk about the theoretical knowledge class can not be finished in a few months, so the braking system is particularly important, but fortunately, Li Tieguo learned these during college,

Moreover, he was born as a train driver to play this hand brake, and he understands the principle and change of the braking system very well, the DF series braking system of the domestic diesel locomotive, he has done in-depth understanding and learning, so the brake system of the diesel locomotive allows him to speak, which is more suitable, but the locomotive in the big gate, small gate, locomotive relay valve, shielding valve, emergency valve, etc., he can only talk about it one by one, so how long it will take can not say,

And after the overhaul of the cleaning and test, and cleaning not much to say, the process is not complicated, but the process of the test is very important, which is related to the effect of the brake system after loading, so here is also a key and difficult point, the test coefficient, the brake system pressure gauge and so on, he is ready to say, after all, will repair but do not know whether the repair is good or not, so this division of labor seems simple but in fact, the burden inside is really not light,

A day later, the work of Li Tieguo and his entourage began, at that time Li Tieguo brought hundreds of non-domain friends, and he actually didn't be a teacher at that time, so he simply sat down with these non-domain buddies in English, more than a dozen people chatted, first from the principle to the specific operation, and then to pay attention to details, etc., as well as the process of cleaning and testing, the level of process requirements, more than a dozen people have to take a month, this is still fast, some non-domain friends don't understand, Li Tieguo is also directly answered in person, Never pull anyone down for the sake of progress,

After all, he came here to ensure that everyone who listened to his explanation could complete the process standard alone in the future, and the non-domain friends were also very smart and united, and many of them would discuss with each other and answer each other that day, which also allowed Li Tieguo to reduce a lot of pressure, and here in the non-domain, the life at night is still good, and the non-domain friends specially set up a bonfire party in order to welcome them, and the barbecue or something is enough to eat,

But anyway, although Li Tieguo is not used to eating, he is also very happy, and dances with them, drinks coconut water together, in short, after a busy day in the evening, the food and accommodation are very good, and the energy is good the next morning, but the non-domain friends are also full of passion to learn, a little bit of understanding, absolutely to ask, after all, people are also learning for their own country, eager to learn all the knowledge, and Li Tieguo They are also very willing to answer these questions for them, after all, international friendship, These party members are here to represent the country and the party, to represent the advanced communist forces, and to demonstrate the country's powerful talents, and the friendship between the countries is fully embodied in them.

And after a few days, Li Tieguo and these people are busy at night, this will start to do work summary, sort out teaching copy, prepare lessons, and discuss the problems raised by non-domain workers, many times they really encounter difficulties, Li Tieguo also has to ask others to answer specifically, after all, he is not an expert, and once he has free time, Li Tieguo and these people have to carry out party affairs propaganda and so on, in short, after a few days they almost have no one to rest in the non-domain except sleeping,

But it is this momentum, such a responsible attitude, has left a good impression on the people of the non-region, and after a few months, Li Tieguo and these people have also taught most of their experience and knowledge.

But there are still many non-domain friends who have not taught, and it is impossible to train some train experts in a few months, so Li Tieguo has no recruitment, so he can only sit in the big classroom to speak, if there are still more than a dozen people and a dozen people, I am afraid that the lecture will not be finished in a year, for the sake of progress and to complete the task, Li Tieguo can only sit in the big classroom,

But sitting in the big classroom and sitting in the big classroom, it doesn't mean that he began to fool his international friends, after he finished class every day, he would still set aside a few hours of personal time in the evening, to ask everyone one by one about their learning situation, study questions, and then answer them one by one, sometimes one night down, he had to talk until 12 o'clock in the middle of the night, sleepy and shaking in place,

But he never took the initiative to walk through, and always adhered to the attitude of lecturing with questions and answers, but as soon as non-domain friends saw that he was sleepy and couldn't open his eyes, they didn't ask at all, and they were also afraid that Li Tieguo would be really tired and lie down, who would talk about it in the future, and among these people who asked questions, many people got along well with Li Tieguo, and there was even a worker named Nikoude who said to Li Tieguo,

He himself had studied in a foreigner's class before, but those teachers always gave lectures to the point and left, and the workers only answered a few questions to him, and said that they were talking after class, but he went back as soon as the class ended, and no one was embarrassed to stop him, only Li Tieguo really stuck to his position, and he didn't go back until the workers were finished.

And Li Tieguo smiled lightly at this, did not say that the support personnel of other countries were good, nor did he say that they were bad, just happy, and a squad leader named Yatulan asked Li Tieguo in his spare time, why are they, technical support experts from China, as if they don't know how to be tired, all day long are either lecturing or preparing for classes, are Chinese really not tired?

When Li Tieguo listened to his words, he couldn't help but be happy, and then he told the squad leader named Yaturalan,

"In our China, Confucius has a saying that is called tacit knowledge, learning without getting tired, teaching people tirelessly, what is there for me, which means that the person who learns silently remembers the knowledge he has learned, and does not feel bored with learning, so for teaching people, what is the difficulty of not knowing tiredness? We are all friends of third world countries, and now the developed countries in the West are blocking our technology and want to empty our country's pockets. ”

"Take this internal combustion car as an example, how many parts and components you can't produce, supercharger blades, advanced CNC machine tools, these things need dozens of tons of rhenium elements in the world, if we don't master the core technology, don't unite to get resources, the problem parts will be returned to the factory to repair in a foreign country will have to be hundreds of thousands or even millions, but to them, maybe just change a holster or steel rim, the cost is likely to not use hundreds of dollars, but to extort hundreds of thousands from other countries, the car is not expensive, But the subsequent repairs are like blackmail! ”

"And this is the power of science and technology, but also the comprehensive strength of a country, we are not tired, but no matter how tired, you are international friends, we are people in one camp, then we must do our best to help you, and this is also the responsibility of our people to come here!"

Li Tieguo's voice was very loud when he said these words, he raised his head, and there was a faint strength in his eyebrows, a kind of unconvincing and full of pride,

As a person who studied in college in his early years, he has some knowledge of his country, and he is always concerned about the situation of the world and the complex situation, and has some understanding and opinions.

He is convinced that his country will overtake in the future after nearly a hundred years of war, catch up with the world's superpowers, this may be a kind of dream, a kind of delusion, but if you don't even dare to think about it, then what courage is there to talk about, a country, a nation, after enduring a hundred years of war, want to use one day or two days, a month and two months to overtake others, foolish dreams, but what about after a generation and two generations? What about three generations, four generations later? The Chinese nation has stood in the East for thousands of years, and has led the world for thousands of years, relying on the spirit of Chinese diligence and bravery, the fighting spirit of the more defeated and braver, fearless and powerful, the collapse of the moment does not mean complete subversion, the sea will eventually withstand the wind and waves, and the great power will eventually rejuvenate and rise, this is only a matter of time, a matter of several generations, Li Tieguo is convinced of this!!
