Long before graduation, Xi Meiyuan applied to study abroad at public expense, so she will soon leave Xia Guo.

Before leaving, she definitely had to go home, so she had to leave Jingshi early.

Xi Meiyuan held back her tears, hugged one by one, her voice trembled a little, "It's very convenient to contact now, when the time comes, we will contact by email, if you dare to forget me, I ......"

"Alright, let's get in, or the train should leave." Gu Baozhu pushed her, as if she was very unsuitable for this kind of occasion.

Xi Meiyuan pouted deliberately, and said unhappily, "Boss, you're too cold, we're all going to separate, you're not sad at all, hum, cold-blooded." ”

Gu Baozhu looked at her funny, and then looked at Yang Hong and Quan Xi with tears rippling, a little helpless.

"The world is so big, and the mode of transportation is so developed, not to mention that you can send emails, and maybe you can have face-to-face videos in the future, don't be sad, let's go, if you don't go, you really miss the train and have to wait for the next trip."

Xi Meiyuan thought about it, but agreed with her statement, "What you said is also right." ”

The development of the country can be said to be changing with each passing day, which is not in the past, who would have thought of mobile phones, computer networks.

No one could have imagined it, but now that the country has realized it one by one, and is even actively promoting it throughout the country, it will definitely be more convenient than it is now.

"Take care of yourself after going abroad, you are the first international student in our dormitory, we are proud of you, come on."

"Er, come on!"

"Come on!"

Xi Meiyuan turned around and entered the train, and her tears could no longer be suppressed.

It's really hard to be separated, and the good memories of college will eventually become memories.

After graduation, everyone went their own way, each went to their own future, and then recalled the college days, it is estimated that only the youth and beauty remained.

"She cried." Yang Hong wiped her tears and said in a choked voice.

Xi Meiyuan is such a strong girl, she didn't cry in the end.

Hmph, dead ducks have hard beaks.

Quan Xi smiled and nodded, "She is a face-loving person, and she doesn't want to cry in front of us, so we don't know." ”

Gu Baozhu patted the shoulders of the two, "Okay, this time the difference is for a better encounter in the future, let's go." ”

People have been experiencing encounters and separations in this life, and nothing is inseparable, so we must learn to adapt and learn to keep good memories in our hearts.

Gu Baozhu turned his head to look over and asked, "When are you leaving the school?" ”

She knew that Yang Hong and Quan Xi's work had been assigned, and they were both in Beijing, but she didn't know when it would be reported.

Yang Hong wiped her tears and said, "Let's go two days, there are still some things to deal with, the reporting time at the hospital is very rich, and before going to work, I am going to go home." ”

If she wants to go home in the future, she can only wait for the vacation, and this time when she goes home, she has to bring her own object.

"Remember to call me when you get married." Gu Baozhu nodded.

"Okay."

After bidding farewell to her roommates after the graduation ceremony, Gu Baozhu plunged into the laboratory again.

After a little more than a month, all the materials and components had passed the performance tests, and the next step was to assemble the parts, which meant that their lithography machine project was nearing completion.

For the operation of the lithography machine, it is usually done by system control.

Therefore, after the assembly is completed, a complete set of operating systems needs to be made.

These system controls typically include operator interfaces and software for setting exposure parameters, controlling motion axes, monitoring processes, and more.

Operators also need to be familiar with the basic operation and control methods of the lithography machine to ensure good lithography results and production efficiency.

A month later, a nano-scale lithography machine independently developed by Xia Guo scientists was officially born, and everyone held their breath and stared at this lithography machine, which can be said to be the most advanced in the world.

The appearance of this lithography machine made all of them see the strength of Comrade Gu Baozhu.

It was a truly exciting moment and a historic breakthrough for their country to build the world's most advanced lithography machine from scratch.

"This is the lithography machine we built?"

The lithography machine was obviously born by them, but they still couldn't believe it.

They couldn't even believe they actually did it, what a great moment it was.

They stared at it and couldn't help but think, is this really the lithography machine that they themselves spent more than a year building?

It's incredible, it's unbelievable!

"Any questions?" Gu Baozhu chuckled, a little bitter.

The seniors looked excited with a hint of disbelief, as if it was hard to believe that we had made it ourselves.

But the truth is that they made it themselves.

This is the joint effort of all the scientists present.

The man wiped his tears and said with a little choked up, "No, no problem, I'm just happy, happy." ”

As they spoke, many people wiped the corners of their eyes.

With the first lithography machine, there will be a second lithography machine.

With the lithography machine, they can produce chips independently, which greatly saves imported foreign exchange.

It's just that they think about the cost of producing a lithography machine, and they are a little worried.

Even if they don't know, they can estimate that this lithography machine cost nearly tens of millions of dollars.

And that's not even counting the cost of broken materials that failed, and it is not possible to mass-produce.

Now that the lithography machine has been built, the next step is to test its performance.

The matter of testing the performance, Gu Baozhu directly handed it over to Hu Lao, and then she had to design the integrated circuit on the chip of her own defense bracelet.

Because there are so many functions involved in the defense bracelet, the integrated circuits are also complex.

The core technology of the defense bracelet has been conquered long before the lithography machine, and the next step is to design and verify the chip.

While designing the chip, Gu Baozhu also wrote a report on the production data of the lithography machine, which recorded the relevant technology and data analysis in detail, and this busy time was another month.

After more than a month of testing, Hu Lao and other experts are becoming more and more excited and energetic day by day.

Because through this month's test, they found that the lithography machine they made can make nano-scale chips, up to 500 nanometer chips, how can they not be excited, this is a breakthrough.

After Gu Baozhu listened, he was a little helpless, "Your test is too conservative. ”

"Our lithography machine can make chips up to 18 nanometers."

"How much?" They felt that their ears might have misheard and looked at her in disbelief, "How many nanometers?" ”

Gu Baozhu smiled and said confidently: "I said, our lithography machine can make chips up to 18 nanometers. ”

The reason why she wanted to make a lithography machine was to make the chip needed for the defense bracelet.

The defense bracelet she designed has three functions: alarm, defense, and attack, and it belongs to sonic defense and sonic attack, which has high requirements for the chip.

Micron-level chips can't be used at all, so she thought about making a lithography machine.
