For graduate students, there is no difference between weekends and weekdays.

At least for Mu Jingchi and Zhang Chuyang, there is no difference.

In addition to eating and going to the cafeteria, the two spent the rest of their time in the laboratory and office, doing experiments with their senior brothers, checking literature, and researching materials.

Although both of them are now engaged in the direction of metal materials under extreme conditions, they are not in the same experimental team.

However, one thing in common is that their team is not responsible for the team led by Professor Yang himself, but the doctoral topics of Professor Yang's team.

Among them, Zhang Chuyang is the direction of failure analysis of mechanical parts, which is a topic of independent application.

The experimental project of Mu Jingchi is not an independent application, but a cooperation with Geely Automobile in China to make a breakthrough in the direction of automobile engine materials.

To put it simply, it is an improvement on existing materials.

The team that Mu Jingchi followed was the engine cylinder head.

The engine cylinder head is mainly used to close the cylinder to form a combustion chamber, and the cylinder head bears the high temperature and high pressure of gas, and the mechanical load and heat load.

Cylinder heads should be manufactured with materials with good thermal conductivity, high mechanical strength at high temperatures, can withstand repeated thermal stress, and good casting properties. At present, there are two kinds of materials used, one is gray cast iron or alloy cast iron, and the other is aluminum alloy.

Cast iron cylinder head has the advantages of high temperature strength, good casting performance and low price, but its thermal conductivity is poor and the weight is large. The main advantages of aluminum alloy cylinder head are good thermal conductivity and light weight, but its high temperature strength is low, it is easy to deform in use, and the cost is high.

Mu Jingchi's team is researching aluminum alloy materials, mainly to improve their high-temperature strength.

Every day with the team is busy.

On the one hand, spectroscopy, electron spectroscopy, diffraction analysis, electron microscopy analysis, and various mathematical, physical and chemical calculations are done.

On the other hand, the analysis of the material processing process also needs to be calculated. Sometimes you even need to participate in team discussions.

Although he was busy and tired, he was used by those senior brothers, but Mu Jingchi was very happy.

Because he has really learned, the knowledge in the textbook is different from the previous one. If the previous knowledge was flat, now after the combination of theory and practice, knowledge has become three-dimensional.

Every evening, after Mu Jingchi returned home, he would go to the study.

Although it is very late, although it is very tired, I will still go to the study room and sort out the knowledge little by little through the single study service provided by the system.

this day.

Mu Jingchi rests at home, which is a rare time to rest.

Because the last experiment failed, the materials produced by the experiments not only did not meet the standards, but even lower than the existing cylinder head materials in terms of performance.

Failure in materials experiments is not uncommon, and basically everyone is used to it. When Mu Jingchi didn't join the project team, he had already failed many times.

However, because of the failure of this experiment, Mr. Wang, the leader of the team, still took a day off.

Mr. Wang's full name is Wang Binbin, a teacher at the School of Materials Science and Technology of Huaqing University, and he has been in the position of lecturer for five years, and he can be rated as an associate professor only short of key scientific research achievements.

Some schools may be obsessed with papers and impact factors for evaluating professional titles, but Huaqing University's professional titles are more stringent and require significant scientific research achievements.

After all, there are not many people who write water papers.

Many people make materials for the purpose of brushing performance, and after brushing the performance, they will go to the tall instrument to characterize it, just to finally publish a natural sub-journal. However, the materials used are scarce minerals, expensive raw materials, and the synthesis methods used are completely infeasible in industry.

This kind of material research has completely lost its meaning.

In Mu Jingchi's view, real scientific research should understand the root cause of material failure, go deep into the structure and properties of materials, understand the principles of physical and chemical changes of materials, analyze the defects in material processing technology, and finally design low-cost and easy-to-prepare materials with industrial potential.

Lying on the sofa in the living room, enjoying the convenience brought by the system, Mu Jingchi watched the entertainment variety show broadcast on the Xiaomi 75-inch TV.

Because there is Fang Yihan on it.

With Mu Jingchi's song "Youth Tour", he successfully regained his popularity, especially Douyin's various uses of this song.

"Youth Tour" depicts the love story of young people, and the lyrics and songs of Chinese style seem to be very meaningful, and the young lady in Douyin pretends to be an ancient young lady and records a small video.

Soon the song spread to everyone.

Fang Yihan, who has returned to popularity, has also been invited to participate in many variety shows.

Mu Jingchi, who was watching a variety show, was disturbed by the vibration of his mobile phone.

Because of experiments and studies, his mobile phone ringtone has always been set to vibrate.

"Chizi, the cover of "Luzhou Month" is ready. ”

It was Shen Chuan from the 'Chaonan Music Studio' who called, bringing good news to Mu Jingchi.

"Send it to me. ”

After so many days, "Luzhou Month" is finally completed, and the cover of the song is the last step, as for the MV, Mu Jingchi never thought of doing it himself.

Either find someone to shoot, or don't do the MV, anyway, he doesn't have the time and energy to do it himself.

Mu Jingchi hung up the phone and came to the study, first turned off the system's 'active thinking' function, then turned on the computer, and waited for the cover to come over.

Songs are generally transmitted to NetEase Cloud, and this time is no exception, to be transmitted to the Internet, a cover must be needed.

The cover was quickly passed around, and it was a very detailed antique map.

On a starry night, the sky glows with a hazy moonlight, and the moon is reflected on the lake. And beside the lake, a figure stood, looking up slightly at the crescent moon hanging high in the sky.

The figure is Mu Jingchi, but due to the light design, only a blurry side can be seen, with a bit of a lonely temperament.

Not bad.

Mu Jingchi nodded, and then uploaded the song "Luzhou Month" to Netease Cloud. Unlike before, Mujingchi has set a fee.

In the past, the songs were not very good, so there was no charge, and they were completely free.

And now it's different, his songs are going to start charging.

2 yuan a song.

It's not that it's free for members, it's not 2 yuan to download, it's 2 yuan to buy this song. If you don't spend these two yuan, you can't audition.

Mu Jingchi has retired from the entertainment industry, and he will not enter the entertainment industry in the future, and the road to gaining popularity with free songs is of little use to him.

It's better to exchange the song for money, and people who like this song will naturally spend 2 yuan.

After thinking about it, Mu Jingchi still posted a message on Netease Cloud's personal account to his fans and friends who have always supported him.

"The new song "Luzhou Month", please enjoy!"
