Before Liang Yuan finished reading the document, he vaguely heard a few greetings from "Mr. Li" and "Mr. Li".

The two girls opened the door of the office compartment and cheered Aunt Liang and ran out.

Li Yuanling was wearing a white coat everywhere in the science and technology park. She also had a small piece of aluminum strip in her pocket. Several technical engineers were holding calculation paper and were surrounding Li Yuanling and asking what they were asking.

Seeing the two girls coming out of their office, Li Yuanling picked up the pen and quickly wrote several sets of equations on paper, sent away the technicians who had just surrounded him and asked questions, and then said to the two girls with a smile: "So early after school today? Why do you remember to come to Aunt Liang's side?"

"The last class today was a boring labor class, and my sister and I quietly ran away."

"Aunt Liang, Xiaoyuan is back."

"It turned out that little bastard is back. I asked why Jiajia skipped class." Li Yuanling pinched Ning Wanjia's cheek with a funny look.

After talking to the clerk outside the office, Li Yuanling walked into the interior room.

"Xiaoyuan, you are still used to living abroad. Have you finished the immigration procedures? Jiajia, a well-known overseas Chinese returned to visit relatives, said whether we should celebrate in the evening?" Seeing Liang Yuan staring at a stack of documents seriously and pretending to die, Li Yuanling said with some teasing.

Liang Yuan listened to his mother's words that seemed wrong, and quickly threw away the "Feasibility Analysis of the Chai Ran Joint Power Device and the Fiscal Joint Power Device for Ground Armored Vehicles" in his hand, and rushed over.

"As the successor of ** career, I was born in China and died in China. If I really dared to immigrate, my dad wouldn't throw me out of my home..."

Liang Yuan took Li Yuanling's white coat just taken off, but he knew that his mother was complaining that she had more time abroad than at home this year.

"Just put the work jacket outside. Look at who has a white coat hanging in the big wardrobe." Li Yuanling looked at Liang Yuan with laughter and tears, and finally put the white coat into the closet in the corner of the wall to hang it up.

Liang Yuan went abroad to slept with Jardine Mahjong, and Comrade Lao Liang went to Dandong to take over as director. Li Yuanling, who knew that there was no concern at home, simply moved many of the living facilities at home to the office.

At this time, Liang Yuan did not dare to complain, "The white coats of employees in the science and technology park are hung in the work wardrobe. Only those with a large office like you, can move the large wardrobe at home to the workplace, and can stand and speak without any pain in the back of your back, pick on what should be hung in the big wardrobe..."

"Uh, my mother just said to celebrate. My mother has advanced to the official director's wife. It's time for us to celebrate well in the evening."

"You little bastard, the director's wife can't even have any fakes?"

"That's it, that's it. With me helping him to take care of Director Liang or Minister Liang, my dad will never think of turning out your palms in his life."

Liang Yuan had no moral integrity and threw Comrade Liang, who had just been promoted, as a cushion. He fooled the matter of not returning home for a long time in just a few minutes.

The two girls were still conscientious. When they thought about celebrating this, Director Liang Da, who should notify the main character of the matter, and called the Dandong Railway Branch with a smile.

"Mom, what is this? Is the new material for the engine?" Liang Yuan turned his hand and asked curiously.

Your uncle said that you specially customized the aluminum materials from the United States. You just arrived at a truck outside and asked your mother why did you remember to ask me?"

"Oh, it turns out that the Liberation Truck at the door was pulled from an aluminum strip."

Only then did Liang Yuan remember that he had instructed Qilian Mountain to secretly bribe Grumman Aerospace not long ago.

"From the product report, these aluminum materials have good corrosion resistance and poor toughness. Where do Xiaoyuan plans to use it?" Li Yuanling looked at Liang Yuan with a smile.

A large-scale purchase of garbage metal materials that look beautiful but are actually useless. As the helmsman of the group's aviation technology, Li Yuanling must be concerned about it. Of course, no one will bear the blame for Liang Yuan's vision and ability. As a result, Li Yuanling did not take much effort to figure out his son's little thoughts hidden well.

"First find a warehouse on Changbai Island to put it in, be prepared for any trouble."

Liang Yuan looked at his mother's expression and knew that his little move of bribing Grumman's senior management was exposed.

However, bribery is not a good moral worthy of publicity. Considering the fact that he and Dongda University used sponsorship to skip classes, Liang Yuan quickly changed the topic.

"Hey, why did the group resume trade with the United States so quickly?" Liang Yuan was a little surprised.

"The contract under execution is not included in the subsequent embargo. In fact, we have resumed normal cooperation with the United States in the past week. Xiaoyuan, Jiajia and Feifei discovered the ab Americans have been thinking about it." Li Yuanling's tone was a little proud.

As for the history of Liang Yuan's previous plane, the United States did not completely close the negotiation and trade doors after the incident. The business agreements reached were no longer within the scope of embargo. In less than half a year, negotiations between the Republic and Grumman started on the issue of continuing to advance the Peace Pearl Plan.

The problem is that after the incident, Grumman, who was carrying out the Peace Pearl Plan, became the only military-industrial enterprise among the large American companies that was qualified to continue to deal with the Republic, and then the capitalist's urinary nature took a hopeless attack. As the monopoly, capital's sky-high price instinct is simply a deep instinct.

Grumman raised the price and shouted that the Republic had to pay an additional $200 million to continue implementing the Peace Pearl Plan. I won’t mention whether Grumman was fishing. At that time, the $200 million at that time was tantamount to the sky-high price for the Republic.

In addition to the Republic's misjudgment of the Soviet political situation, the two sides argued countlessly about the resumption of work on the Peace Pearl Plan. Until the fall of the Northern Iron Curtain, the external strategic situation in the Republic was reversed, and the Peace Pearl Plan ended and there was no more.

After the end of the Peace Pearl Plan, the Republic still obtained a series of core equipment including 1553 bus, apg-66 radar, fire control computers, navigation radars and other core equipment. Later, the Israelis complained sourly, "We just sold some weapons to China to make some hard money, but you bastards (the United States) have taught China how to design these weapons."

Tactically speaking, the Peace Pearl Plan failed, and the J-8 fighter jets failed to completely complete the improvement plan and gained the ability to confront the Soviet Air Force front-line aircraft fleet represented by the counterfire. However, strategically speaking, the Peace Pearl Plan played a very important reference role in the transfer of the Republic's industrial system from Soviet-style standards to Western-style standards. It can be regarded as the cornerstone technology of the Republic's future military-industrial system.

The only regret is that the famous Shengfei Company seemed to have indigestion after leaving Grumman's crutch. The subsequent test flight work of the J-8 fighter jet from Grumman is no longer the focus of Shengfei. The entire Shengfei was extremely decisively put into the arms of Su 27, opening up the perfect evolution from Shengfei to Shenghoi.

Several years later, the 901st Institute, which has evolved into Shenghuoxid, uses the simple summary of "the mechanism and system that has long focused on technology and introduced light digestion and absorption. It has failed to implement the predetermined function of the J-8 fighter jet in the Peace Pearl Plan" to completely conclude the five-year five-year period spent.

However, with Liang Yuan, the messenger in this era, the details of history have long been beyond recognition.

Because someone played a guest role in an arms dealer, the two sides in the Middle East were still fighting fiercely. Through the Republic, the second arms dealer, like Grumman, Hughes, Westinghouse and other arms dealers, they lived a relish with their lives.

Grumman Aerospace, which was originally half dead and tight, has obtained more than $600 million in operating income due to Liang Yuan's accident in the past two years. After the A7 attack aircraft entered China, Grumman unified the US Navy's flight deck five years ahead of schedule, winning the manufacturer of the A7 attack aircraft, Lynn Temko Watt.

At this time, Grumman not only shouldered the official Pearl of Peace of the Republic, but several cooperations with Yuanjia were also underway.

When the incident happened, the 14 fighter jet's overhaul line on the Republic had not finished the final project, and the negotiations on using SBE Aero engine to improve the reliability of the 14 fighter jet's engine also came to an abrupt end.

Influenced by the memory of the previous plane, Liang Yuan was mentally prepared for the embargo and never thought about the possibility of resuming exchanges between China and the United States in a short period of time.

"Is it related to the resumption of communication related to superconducting materials?" Liang Yuan asked.

Due to fear of being confined, Liang Yuan was afraid to avoid the subsequent development of ab superconducting materials, but he did not know the progress of negotiations between China and the United States on superconducting materials.

"If that accident hadn't happened, the agreement on superconducting material to replace metal surface treatment technology will be signed in the past few days. However, after the United States announced the embargo, the teacher immediately responded to the call of the US government and interrupted the negotiations..." Li Yuanling said with a smile.

Superconductivity is purely Liang Yuan cheating. Magnesium diboride is like a rock. In the 1990s, there was no theory or guess pointing to a simple compound with high temperature superconductivity. It can be said that as long as the Republic does not spit, Americans can only play. I guess I guess I guess I guess I guess I guess I guess even if I get nothing for ten years, it may be a high probability event.

The general team responsible for the negotiation of superconducting single crystals sneered at the US government's embargo. The US negotiation team leader J?G? Brandt always believed that superconducting materials are new civilian technologies that benefit all mankind, and are not at all against the weapons in the US government's ban.

Of course. In the report submitted by General Motors to the US Department of Commerce and the Industrial Safety Commission, the negotiations on superconducting single crystals were defined as technology introduction. As a technology backward in superconducting, General Motors insisted that its own situation was not within the scope of the US government's embargo regulations.

"Change the metal surface treatment process? At the beginning, didn't my mother say she wanted to change the single crystal alloy?" Liang Yuan asked in surprise.

"If you change to a single crystal alloy, GM insists that you can only give the first generation of single crystal alloy rene n4. The latest generation of rene n5 single crystal alloy has significantly enhanced its ability to resist high temperature creep."

What the hell is super elements? Liang Yuan was a little puzzled. He made a brand new superconducting material to fool GM, and GM returned a brand new super element on the single crystal. GM was very neat and learned.

Liang Yuan rolled his eyes and tried hard to squeeze out the few memories of single crystal alloys in his previous life.

"If we only replace the first generation of single crystal alloys, we feel that it is a loss. The Shengjing Institute of Metals, Chinese Academy of Sciences has already produced domestic single crystal alloys with the same performance as rene n4. If we replace the first generation of single crystal alloys, it is actually only equivalent to exchange for a complete single crystal production process."

"What is the lifespan of our single crystal alloy relative to American products? What is the yield rate?" Liang Yuan then grasped the key to the problem.

For the Soviet-style R&D system in the 20th century, performance has never been a shortcoming, and it is relatively simple to sacrifice part of the lifespan to achieve excellent performance.
