Students who are eager to learn and feel that they can keep up with the progress can be free to go to the lecture hall to listen to lectures. If you don’t understand the content at the academic report, you can also record it and watch it repeatedly. Therefore, shooting is not prohibited here, and you will also
Students are encouraged to record their studies. It is only recommended that students try not to make the videos they shoot public, just for their own learning.
"Hey, okay, you're studying~" the roommate quipped.
"I think he speaks very well, too."
At this time, one of the four people suddenly said. It was the only girl majoring in physics in the dormitory. Unlike the others, because of the professional matching, she has been listening subconsciously since Chen Mo started speaking. She started at Chen Mo.
When writing on the whiteboard, your eyes never left the whiteboard.
"I can't see clearly here, I'll go ahead and listen."
As he said that, he followed the demon, staring at the whiteboard, and his subordinates quickly and messily pulled out a calculation book from the small bag that followed, and ran forward.
Several people looked at each other.
Alas? No, why are you going to the front suddenly?
Several people silently stretched out Erkang's hand behind them.
"You're back!"
It’s not that you stop the girl from rushing to the ocean of knowledge, but mainly because you have forgotten that your tutor is sitting in front of you? Have you forgotten that you have dragged his research report to him yet! Several people are watching him
He looked at the girl sitting in front of her mentor Professor Carter, silently wiped her cold sweat.
very good,
Very brave!
Girls dare to be so brave, they dare not. Although M University is famous for its competition, because it is too intra-study, it can screen and dismiss nearly half of the total number of students at the end of the first year of undergraduate school, and everyone who can stay is a ruthless person. They
They were no exception. But they didn't dare to run to the first row at this time, and were stared at the back of several professors, and their scalp became numb after thinking about it.
But when I saw my roommates so interested in the lecture, I couldn't help but become interested. Although the few of them were not majoring in physics, they were all related science and engineering majors, and they could understand it even if they listened carefully. I couldn't help but listen.
I heard it and moved several positions in front of me. Before I knew it, I put on my glasses, took out my notebooks, and copied the blackboard.
"The structure of the spr-mf sensor we designed is shown in Figure 1. The double-core mf contains three layers of air holes arranged in a regular triangle lattice. The lattice constant is l and the air hole diameter is d2. The two optical fibers
The cores are located in the corresponding positions of the second layer air hole and are marked 1 and 2 respectively. In order to better adjust the effective refractive index of the core base mold and enable the sensor to operate within a wider wavelength range,
We introduced 2 small holes filled with the sample to be tested in the central area of the fiber core, with a diameter of d3..."
While explaining, Chen Mo pointed to the schematic diagram of the transverse section of the sensor on the slide with an infrared pen.
Several old men in the audience were also very interested when they heard this, and whispered to communicate with Teacher Liang beside them.
...
Just at this moment, Lu Wenxuan and several professors walked into the lecture hall together.
"...Is that so? I can take on this speech at a young age. The teacher really dares to hire people. I have to take a good look... It seems that today's report will definitely be very lively." Lu Wenxuan said with a slight smile.
He smiled and chatted with several professors. While chatting, he walked into the lecture hall.
Looking at the doors in the huge lecture hall, I paused and raised my eyebrows slightly.
He didn't say anything, but Jack beside him spoke for him first.
"It seems that this report will be unpopular, why are there so few people? Teacher, will their report not start yet?"
Lu Wenxuan pressed the low smile in his heart and pretended to scold him:
"Jack! Don't mess around."
"It seems that I am a little younger. I may be the first time I went on stage to give a report. I was very nervous. It's okay, and I don't care if there are many people listening to the report below." Lu Wenxuan said to his friends with a smile.
"It's true that there are fewer people, maybe it's a meal time... It's normal that there are fewer people, and the papers are still very good. I've read them from Lao Liang before." The professors here didn't think anything at all, but after hearing this,
Thinking of my morning report meeting and the number of people who held the report meetings before, the number of people in this huge lecture hall was indeed pitiful. Except for the professor who had read the report paper, the others were called by Professor Liang Rui.
The professors looked at the young man on the stage from afar and frowned slightly, wondering if it was worth spending this time on the trip.
"If you can be appreciated by Professor Tom, the paper I reported will definitely be good. Let's go and take a look." Seeing this, Lu Wenxuan slightly pulled the corner of his lower lip.
"It's just that there are few people... I won't let you talk." Jack followed the few people into the door while whispering.
...
"Of course, we also fully considered the interference problem when designing. In order to improve the signal-to-noise ratio of the sensor and eliminate crosstalk between the sample channels, the central area of the fiber has only one diameter d1 and the inner surface is plated with ito (thickness t)
The large circular air hole is used as the sensing channel for the sample to be tested.na is the refractive index of the sample to be tested, and its value is between 1.423 and 1.513; the refractive index of the air is 1. The substrate material of the optical fiber is si o2,
Its refractive index can be calculated from the sellmeier equation... where: l is the wavelength of incident light. Ito is the plasma material, and its relative dielectric constant e can be obtained by the Drude model calculation..."
While talking, Chen Mo used a black marker to write formulas on the whiteboard. Because of his fast calculation ability, he almost substituted the given parameters while giving the formula and obtained the result again. Because there were too many
In a calculation process, everyone has traces to the conclusion of each data, and it is not tiring to listen to it at all.
I clearly understood the operation and reasons of each step. Even because Chen Mo brought the calculations, he saved me the complicated time of his own calculations, and even saw this research idea clearly. This is not the case for practice or computing experience.
With enough, it was very friendly with M-college students who were struggling.
Several professors also discovered Chen Mo's intentions and laughed friendly.
The students of several professors were fine. They had many experiments with the professors. They could keep up with these calculations even if they were slower, so they would not be too laborious to listen. However, they were all a little surprised by Chen Mo's calculation speed and mental arithmetic ability.
And if he can still take care of them in such occasions, he will give a report on the communication meeting at this level. Aren’t he nervous?
Li Shuying and others are fine. They are more professional and not right. They don’t have to fully understand the report. They don’t think it’s a big deal. But for eight or nine people present, they are doing this for today’s “fiber” theme.
For M college students who studied the subject, they all felt that they wanted to hold the lecturer and kiss him hard! Because this was the most exhausting thing they have ever heard from the morning to now. Because they really want to understand it.
, so I was very tired of listening to every show. This one was a rare one that was not stuck. I had the urge to cry inexplicably. Finally, I didn’t feel like a mentally retarded waste. They had been rubbed for a long time at this time
She was so scared that she burst into tears. The most rare thing is that the content of Chen Mo's research report is not low.
What kind of gods are this? Is it so friendly to these monks?
So, in a large-scale exchange forum of thousands of people.
"Brothers, have you finished your meal? Are you still listening to the lecture in the afternoon? Current location: Classroom ** on the 5th floor of Building C, come quickly, there is a pretty good lecture here."
"Good guy, I'm in the cafeteria. I know the lecture you mentioned. It's really a fairy time to arrange it at a little bit. It seems that the speaker has never heard of it. I feel that the value is generally enough, so I didn't listen to it..."
"It's great, it's great, it's really great! Come quickly, while there are still few people! I'm telling you that Professor Charles Charles and Professor Carter are both here."
"Good guy! Professor Charlie?! I'll come now!"
"This lecture is of great value. I really regret it if I miss it. The big guy who gave the speech explained it too clearly. Come quickly!! I have a premonition that if you don't come again, the classroom will be filled soon! I see that there are so many in the classroom.
Everyone was lowering their hair and sending messages, and they should be calling people. Well, someone came in from the back door."
"Is it a classroom on the 5th floor of Building C? Come now!"
Some of the students at M University who were sitting there took out their mobile phones and sent a lecture location link to the classmate and friend who had been hit and vomited in the morning. Someone posted the lecture name and location on the campus forum.
