Chapter 151: Opening the Eyes for Fighter Planes [Subscription Request]
Wang Haoran hurriedly asked: "Lijuan, what's wrong with you? Are you feeling a little uncomfortable?"
Lin Yaling, who was standing beside her, was moved and asked, "Have you not taken any safety measures recently?"
"I'm afraid it's happening again?"
Xiao Renming lowered his head and coughed twice, then picked up a piece of braised pork and ate it.
He is not in a position to participate in this topic.
When Wang Haoran heard his mother-in-law say this, he thought to himself that he had indeed not taken any safety measures recently.
Because they wanted to have another child! They had to have both a son and a daughter.
So, they have been working hard recently, hoping to create another little man.
Wang Haoran brought Xiao Lijuan a cup of water soaked in lemon slices, cooled it a little, and asked Xiao Lijuan to drink it.
Lemon is rich in vitamin C, dietary fiber and minerals. It can increase the activity of digestive enzymes and has a good effect on improving morning sickness.
"Lijuan, drink some lemonade."
Wang Haoran said while putting his arm around Xiao Lijuan's shoulders.
Xiao Lijuan smiled and said, "Thank you Haoran, I'm feeling better now."
Her heart felt warm at this moment.
Wang Xinghai is already over one year old and has just learned to walk, but he still has difficulty speaking and can only speak a few words at a time.
He blinked his big dark eyes, which were full of confusion and ignorance.
"Mom, I'll be good and won't make you angry." Xiao Xinghai sat on Lin Yaling's lap and said to Xiao Lijuan.
He thought his mother was angry.
This well-behaved look aroused the love of everyone in the room.
Wang Haoran smiled and touched his son's head, saying, "Xingxing, Mom is not angry, Mom may be feeling uncomfortable."
Wang Xinghai nodded and said, "Dad, Mom might be sick. Take her to get an injection and she'll be fine."
Lin Yaling kissed her grandson lovingly and said, "This child is only a little over one year old, but his logic in speaking is so clear. He even knows how to feel sorry for his mother."
"It's so painful."
Wang Haoran also smiled and said, "Then I will take my mother to the hospital for an injection in two days."
Wang Haoran thought that he had to take his wife to the hospital in the next two days to see if she was pregnant.
If I get pregnant, that would be great.
However, considering the Chinese New Year, it is estimated that there will not be many doctors on duty in the hospital.
If we want to take Xiao Lijuan to the hospital to check whether she is pregnant, it will probably have to be after the fifth day of the lunar year.
However, Wang Haoran thought again, I have a ready-made formula in my mind for making pregnancy test strips.
The main test for pregnancy is human chorionic gonadotropin, also known as HCG.
Wang Haoran decided to take some time tomorrow to go to the school’s chemistry laboratory and get some HCG test strips for testing.
However, to be honest, as long as the menstrual cycle of women of childbearing age is significantly delayed, the possibility of pregnancy can reach more than 90%.
Xiao Lijuan drank some lemon water, and the discomfort caused by morning sickness disappeared significantly.
Upon questioning, it turned out that her period had been delayed for seven or eight days.
She has been a little busy recently and forgot about this matter.
Lin Yaling said: "The period has been delayed for seven or eight days, which means it is certain that Juanjuan is pregnant."
"I've already given birth to one child, so I have some experience with this second one. Don't worry, just wait patiently for a few days until the hospital is open, and then draw blood for testing."
Then, Lin Yaling glanced at Wang Haoran and said, "Haoran, you will have to work hard again in the next few months. Don't touch Juanjuan because you have to protect the fetus."
Wang Haoran quickly said, "Mom, I know."
……
That night, because Xiao Lijuan was suspected of being pregnant again, she was arranged to go to bed early to take care of the fetus.
Wang Haoran was forced to live with Xiao Renming in the Peking University staff housing estate.
The father-in-law and son-in-law went to the house over there, ordered a few more dishes, drank some beer, and chatted while keeping watch.
Only then did Wang Haoran realize that Xiao Renming had recently been assigned a task to research Doppler pulse radar.
Moreover, this task was assigned to several scientific research units.
Obviously, this matter should be urgent.
Xiao Renming said: "Yosa and Daxiong have already put the third-generation fighter into service."
"We still mainly use second-generation fighters."
"In terms of air force, we have lagged behind the world's mainstream powers for many years."
"And in order to upgrade from a second-generation fighter to a third-generation fighter, in addition to mobility, long-range strike and long-range warning fire control radars are introduced, which can 'see' the opponent from a long distance."
"So, we are now seriously behind in the air force."
"This kind of backwardness would be extremely fatal on the battlefield."
"Therefore, the country is now determined to make a rapid breakthrough in long-range fire control warning radar."
Xiao Renming introduced him to Wang Haoran.
After listening to this, Wang Haoran nodded and said, "Dad, you are right!"
"We must hurry up and develop the third-generation fighter jets."
"However, if we want to develop a third-generation fighter, I estimate that the problems we have to overcome are not just Doppler pulse radar!"
"We need to study aircraft engines, aircraft flight control electronic systems, and air-to-air missiles."
Xiao Renming nodded and said, "Yes, there are indeed many problems that need to be solved."
"As for the Doppler pulse radar that I am currently researching, there are also many technical difficulties that need to be solved."
Wang Haoran smiled and said: "The biggest technical difficulty of Doppler pulse radar is actually the mutual constraints between spectrum aliasing and detection depth and speed measurement..."
Wang Haoran told Xiao Renming about some of the technical ideas about Doppler pulse radar in his biochip memory capsule.
In the current Dragon Country, the mainstream fire control radar is still a single-pulse radar that uses a perverted Cassegrain system. It is far behind the Doppler pulse radar that is now commonly used in various Lizard countries.
After hearing this, Xiao Renming nodded repeatedly and said, "Haoran, I am greatly inspired by what you said!"
"I almost forgot that you developed a gun-aiming radar before, haha!"
"Why don't you take part in my project?"
"Let's take charge of this project together and try to get it done as soon as possible."
Wang Haoran smiled and said, "Dad, I have a lot of work to do here. When you need my help, I'll just go and help you. There's no need for me to join your research group, right?"
Xiao Renming shook his head and said, "No! You must participate!"
"After listening to what you said just now, I have broken through the biggest bottleneck in my research."
"I can't take advantage of you like this."
"Let's have a joint host for this topic."
"When you are busy, just go and do your work. If I have any questions, just give me some advice."
Wang Haoran had no choice but to agree.
In fact, as long as you understand it, Doppler pulse radar is just a relatively simple radar and it is not difficult to develop.
Doppler radar is actually a radar system that makes full use of the principle of Doppler effect.
This type of radar emits "Doppler pulse signals" to detect situations in the distance.
Doppler radar can be divided into single pulse and multi-pulse.
The radar systems used by these two radars are different.
Single-pulse Doppler radar receives multiple echo signals from the target at the same time and uses the phase difference of these signals to determine the target's defense line.
Multi-pulse Doppler radar obtains target information by emitting multiple pulses. It sends and receives signals at the same time, processes large amounts of data, and can track multiple targets at the same time.
Single pulse is more accurate in angle measurement, while multi-pulse Doppler radar has advantages in distance and speed measurement.
But for fighter jets, powerful multi-pulse Doppler radar is obviously more suitable.
Obviously, single-pulse and multi-pulse Doppler radars each have their own advantages and disadvantages.
In the past few years, the Kingdom of Yusa has been very active, hoping that the Kingdom of Long will stop developing its own weapons and instead buy weapons from Yusa. Yusa can provide the Kingdom of Long with all the advanced weapons, leaving it completely defenseless.
Of course, Long Guo didn't believe this.
If a country cannot develop weapons independently, it will sooner or later become a vassal. Therefore, now, after entering the 80s, Longguo is still stepping up its efforts to develop weapons independently.
That night, when the clock struck 12, Wang Haoran went to set off firecrackers and then went to bed.
The next day was the Spring Festival. As the person in charge of Pangu Company, Wang Haoran had to visit the company and comfort the employees on duty.
When he was visiting the company to offer his condolences, several leaders also came to express their condolences.
We had a discussion and had lunch together at noon.
After Wang Haoran finished his meal, he went to the chemistry laboratory of Beijing Institute of Technology.
Although Wang Haoran's main position now is at Pangu Corporation, he still retains a teaching position at Beijing Institute of Technology. As long as he applies, he can use all the laboratories.
Beijing Institute of Technology seems a bit deserted during the Spring Festival.
There were hardly any people in the school.
Wang Haoran plunged into the chemistry laboratory and started making pregnancy test strips himself.
The main substance used to test whether a woman is pregnant is HCG, which is human chorionic gonadotropin.
Once conception is successful, the fertilized egg will continue to produce cell division and secrete chorionic hormone. When HCG enters the mother's blood, it will be excreted from the urine through the mother's kidneys.
As long as the HCG content in urine exceeds a certain normal proportion, it is very likely that you are pregnant.
In the laboratory, Wang Haoran needs to first synthesize the enzyme-linked antibodies used for testing, and then make test strips.
In short, it is quite troublesome to make such a test paper.
As far as Longguo is concerned at present, there seems to be no demand for this kind of test paper for self-checking whether one is pregnant.
Wang Haoran was busy and had just about to produce some results when there was a knock on the laboratory door.
Wang Haoran thought, who could find their way here during the New Year?
Wang Haoran walked over and opened the closed door of the laboratory.
Standing outside the door was Yuan Longfei, the director of Pingu County Machinery Factory, holding gifts in both hands.
"Comrade Haoran, Happy New Year! I come here today to wish you a happy new year." Yuan Longfei said with a smile.
Wang Haoran quickly responded with a smile: "Happy New Year, Director Yuan!"
"Long time no see!"
"Have you eaten? Come home with me and have a couple of drinks."
Yuan Longfei said, "I've eaten. Today I specially accompanied my family to go shopping in the city. Isn't it the New Year? Take a two-day break. I haven't seen you for a long time. Since you are here, I came to see you."
"I originally just wanted to come to Beijing Institute of Technology to ask where you live, but the guard said you were still working in the school laboratory today, so I took the liberty to come here."
Wang Haoran smiled and invited Yuan Longfei to his office to sit down and chat.
After arriving at the office, he was busy making tea and bringing some snacks to entertain the guests.
Yuan Longfei said: "Comrade Haoran, please don't be busy. I just came to visit you today and express my gratitude to you."
"With your help, the diesel engines produced by our Pingu Machinery Factory are now very popular, and the cadres and workers in the factory are very grateful to you."
Wang Haoran thought that Yuan Longfei was a good person.
Let them take charge of the refrigerator production line. It would be great if we could create a pillar industry for Pingu County.
Wang Haoran thought about this and asked, "How is the equipment update situation of your machinery factory in the past two years?"
Yuan Longfei smiled and said: "We have updated some equipment, improved automation and standardization, and production efficiency has also been greatly improved."
Wang Haoran asked: "What was the output value last year?"
Yuan Longfei said: "In 79, the output value of our factory was more than 819 million yuan, and the profit and tax was more than 534 million yuan. The welfare and benefits of employees have been greatly improved. At present, we have become an excellent enterprise in the county."
"Of course, the county pesticide factory is even better than us. They produce several kinds of herbicides and plant growth regulators. Currently, their products sell much more than ours and cover the whole country. Their output value exceeded 10 million last year."
In the 1980s, any Chinese enterprise with production and sales of tens of millions was considered a super-large enterprise.
Wang Haoran said: "Do you want to go further and develop better?"
When Yuan Longfei heard Wang Haoran say this, he was delighted. He thought: What does this mean? Do you want to help us develop some new products?
With the help of Wang Haoran, the motorized tricycles produced by the Mafang Commune Machinery Factory are now sold all over the country. In 79, the annual sales volume exceeded 5 units, and the annual output value reached 1.8 million! The Benma brand agricultural tricycle is now a well-known national brand, and the entire Mafang Commune is now rich thanks to the Benma Company.
"Oh... Comrade Haoran, of course we want to go further. I wonder if you have any good suggestions?" Yuan Longfei was a little too excited and his speech was a little halting.
Wang Haoran smiled and said, "I have a project here, and I think it is more suitable to be implemented in Pingu County."
"If this project is completed, it should be sold well throughout the country. Your Pingu County is likely to become an industrial center in the Beijing area!"
Yuan Longfei's breathing became a little rapid.
"Oh, yes, what project is it?"
"Thank you, Comrade Haoran. I knew you would always be thinking about us. Thank you so much."
Wang Haoran smiled and said, "Have you heard of refrigerators and freezers?"
Yuan Longfei nodded and said, "I have heard of it. We still have a small amount of imported products for sale here, and they are quite expensive."
"It's very useful, especially in the summer. If you can't finish your meat or vegetables, you can put them in to preserve their quality. Of course, you can also make popsicles at home."
Wang Haoran said: "Our research team at Beijing Institute of Technology has developed a refrigerator and freezer production line. We need to manufacture the production line equipment ourselves and invest in building a new workshop. If Director Yuan is willing to invest, this project will be assigned to your factory."
Yuan Longfei was overjoyed: "Thank you, Comrade Haoran!"
"That's great!"
"We do!"
"Our factory has actually accumulated some profits in the past two years. I think if we apply to our superiors, they will definitely agree!"
Wang Haoran smiled and nodded, saying, "Then Director Yuan, go back and apply to the county leaders."
"As long as they agree, the project will be yours."
"If we work overtime, I feel that our refrigerators and freezers should be ready for production by the end of this year."
Yuan Longfei naturally agreed immediately. He could no longer sit still.
He said goodbye to Wang Haoran, and then he personally drove a Modou brand car to take his family home.
Then he went to meet Guo Qing, the main leader of Pingu County.
Guo Qing was naturally quite busy during the Spring Festival.
The whole morning was spent in condolences and inspections.
After lunch, he wanted to stay in the office and take a rest.
I had just laid down on the sofa and hadn't fallen asleep yet when I heard a whisper outside the door.
It seemed that someone was arguing outside the door.
Moreover, the sound was getting louder and louder.
Guo Qing could tell that the people outside the door were his correspondent and Yuan Longfei, the director of Pingu County Machinery Factory.
Guo Qing stood up and walked over to open the office door.
"Leader, Director Yuan said he has something important to report to you." said the correspondent Xiao Qian.
Guo Qing smiled and nodded, saying, "Comrade Long Fei, come in!"
"Xiao Qian, don't stop Comrade Long Fei from coming over next time!"
“Work is the most important thing.”
Xiao Qian quickly said, "Oh, OK."
Guo Qing invited Yuan Longfei to sit down in his office.
"Comrade Longfei, what's the matter?" Guo Qing handed a peony to Yuan Longfei.
Yuan Longfei took the cigarette, lit it for Guo Qing with a match, then lit his own cigarette, took a puff, and said, "Today I went to visit Comrade Haoran and wish him a happy new year. He said he would help us with a new big project..."
Yuan Longfei then told the story of what happened.
Yuan Longfei listened with great interest. He slapped his thigh and said, "This is great news!"
"Then what!"
"We'll build a new factory here in Pingu County! We'll give you 20 acres of land. If you want to build it, build a large factory that can produce more than refrigerators and freezers per year!"
"The county has had some money in the past two years, so it's no problem for us to invest a few million in you!"
Yuan Longfei hurriedly thanked him: "Thank you for your support, leader!"
"Well, I'll make a plan first, and then go see Comrade Haoran in two days to hurry up and get this done!"
Guo Qing said: "When you go, call me too! Let's go see him together!"
"The industrial development of Pingu County is so good now, thanks to the help of Comrade Haoran! I also want to thank him in person!"
