Chapter 165 Depression Dispelled
Liu Hua met Professor Liang Ji in a large office. When Professor Liang Ji knew Liu Hua's intention, he smiled gently.

Professor Liang Ji did not expect that a student would be so concerned about the construction of his hometown, and he could make an analysis based on the existing resources and product market in his hometown. He felt that Liu Hua was amazing.

"Student Liu Hua, the experiment of the new bainite ductile iron grinding ball is still in progress, and the technical conditions are not yet mature, but if you want to use this product in the future, you must first have some excellent foundry workers." Professor Liang Ji briefly explained the situation of the project to Liu Hua.

Liu Hua left Professor Liang Ji's office with indescribable emotion and joy.He has gained a lot today. He can basically understand what Professor Liang Ji said. He found that there are actually many things that are interrelated between different fields.More importantly, he figured out the true connotation of the course "Physical Chemistry".

Professor Liang Ji is a very talkative person. Combining some reaction rules in the experiment, he talked a lot about "Physical Chemistry".

Among the homework Liu Hua has learned is the course "Physical Chemistry", which is a professional basic course for chemical engineering students and a subject that has always been accompanied by chemical research.

When Liu Hua got the textbook "Physical Chemistry" for the first time, he was very surprised and very interesting.

Because when I was in high school, mathematics, physics, and chemistry were parallel and parallel. Why is physics and chemistry combined and become a homework now?

He couldn't figure it out. When he opened the book and flipped through it, he seemed to be able to understand it, and felt that what he was saying made sense, but after closing the book, his mind was clouded.

After listening to the teacher's first class, he realized that the mathematics, physics and chemistry mentioned in high school are actually the first-level subjects in natural science, and there are many branches in the first-level subjects.

There are four major branches of chemistry, inorganic chemistry, organic chemistry, analytical chemistry, and physical chemistry.These four branches are called the secondary disciplines in chemistry. (Now there is one more polymer chemistry, which is called the five major second-level subjects. When we were in school, we talked about four.)
"Physical Chemistry" studies the general laws of chemical reactions, whether it is organic matter or inorganic matter, it studies all chemical reactions or physical processes related to chemical reactions, so it is A branch of chemistry that studies the general laws of chemical reactions, physical chemistry also has a name called theoretical chemistry.

In this sense, physical chemistry is the theoretical basis of the other three major chemistries.It does not involve whether the reaction is a reaction of inorganic substances or organic substances, so when the teacher of physical chemistry gives examples in lectures, he always talks about the reaction of A+B to form C. He will not talk about what substances A, B, and C are, just arbitrary A chemical reaction of the formula, so the study of physical chemistry is the universal law of chemical reactions.

Since the name of "Physical Chemistry" is also called "Theoretical Chemistry", it focuses on the theoretical research of chemical reactions, and also includes the theoretical research of those physical phenomena accompanying chemical reactions.

With the development of science, many branches of physical chemistry have emerged, including chemical thermodynamics, chemical kinetics, structural chemistry, quantum chemistry, electrochemistry, and surface chemistry, which form the three-level discipline of chemistry.

The above branch courses are all professional courses of the Department of Chemistry. Many courses are not taught by chemical engineering majors. As a chemical engineering student, Liu Hua naturally cannot hear these courses. The kind of person who died, so he died with physical chemistry.

Since he started to study "Physical Chemistry", there are many things he can't understand. He is always confused about some concepts in it, let alone other students in the class.

Seeing that he was obsessed with death, Gao Qi also advised him to just remember what the teacher taught, and talk about it later if he didn't understand it. Maybe he listened too much. I don't know which day he woke up, and suddenly he was enlightened, and he understood naturally. up.

After hearing this, Liu Hua could only answer with a wry smile.

Every time I take a "Physical Chemistry" class, he seems to understand all the aspects of knowledge taught by the professor, and he can answer all the knowledge points asked by the professor fluently. All the other students look at him with envious eyes, but only in his own heart. I understand that he is actually looking at physical chemistry through a layer of clouds.

The depression and confusion in Liu Hua's heart led him into what kind of subject physical chemistry is, such a dead end of self-questioning and self-answering.

But today, Liu Hua finally stripped off the shadow of physical chemistry in his heart. When Professor Liang Ji explained the process conditions of the new bainitic ductile iron, he talked about the content of physical chemistry. The empowerment made Liu Hua suddenly understand the importance of physical chemistry in the study of chemical reaction process, as well as the physical phenomena it studies in the general law of chemical reaction, and the decision of the product in the application of process conditions under the same external conditions effect.

Today Liu Hua is in a very relaxed mood. He took the initiative to invite the brothers in the dormitory to have a gathering at the XJ restaurant, and everyone responded positively.

Seeing the arrival of a group of brothers from Tsinghua University, Ayigul happily danced to "XJ Hao" for everyone.

While drinking, Gao Qi felt strange, and asked Liu Hua if he encountered any happy things today?Liu Hua told Gao Qi about meeting and talking with Professor Liang Ji.

After Gao Qi heard this, he was happy for Liu Hua. He lay next to Liu Hua's ear, and said to Liu Hua mysteriously: "Liu Hua, when we go back later, we two have something to say on the road."

"Brother Qi, what's so mysterious? Can't we say it now?" Liu Hua found that Gao Qi had a strange expression, as if he was excited but pretending to be mysterious.

"This occasion is not suitable for talking about serious topics. We will talk about it when we go back." Gao Qi shook his head with a smile.

"Alright then!" Liu Hua didn't ask anymore, but he vaguely felt that what Gao Qi talked about should be related to him.

We returned to school around nine o'clock.

Liu Hua and Gao Qi deliberately walked last, Li Shihong and Song Dajian are commonplace, so no one cares.

The two walked silently, and finally they turned to the basketball court.

"Brother Qi, what happened? Tell me quickly!" Liu Hua felt that Gao Qi was very abnormal today. He said that he had something to tell him, but he didn't say a word for such a long time, and walked away in silence for a long time.

Gao Qi stood still and looked at Liu Hua quietly.

In the shadow of the lights in the distance, Liu Hua saw Gao Qi's eyes staring at him so brightly in the dark night.

His heart was a little hairy, and he always felt that something big had happened.

"Liu Hua, as your introduction to the party, I now solemnly inform you on behalf of the party organization that the party branch in the department has passed the research and you will become a probationary member of the Communist Party of China. The probationary period is one year."

Liu Hua stared blankly at Gao Qi, and was made a fool by the sudden good news.

"Brother Chi, is what you said true?"

"Of course it's true. In two days, the academy will organize a swearing-in ceremony for probationary party members. As a representative of probationary party members, you will speak on behalf of everyone, so you have to hurry up and prepare."

"Brother Qi, thank you!" Liu Hua stepped forward and held Gao Qi's hand tightly.

"You don't need to thank me, your joining has added new blood to our party, and your acceptance as a probationary party member by the party organization today is also inseparable from your usual performance, so you must continue to work hard!"

"Brother Qi, don't worry, I will never let down the party's trust and training in me, and I will definitely be a red and professional revolutionary successor!" Although Liu Hua's voice was not high, he was using his life make a swear.

In the late autumn night, the high and pure moon hangs in the vast sky, which feels so far away.

There were crickets singing nearby, and the cool autumn wind rustled the leaves as if to accompany them.

Liu Hua just felt relaxed and happy.
