Chapter 291 Shocking 4 People
Lin Ling is also an "old fritter" and has defended many competitions.
He skillfully inserted the USB flash drive into the computer, and began to introduce it to the five mentors below.
"Helan Mountain purple mushroom, this is a kind of food with high anti-tumor and anti-oxidation effects. This time we are studying its molecular mechanism, and hope it can act on the human body."
Lin Ling had a natural look on his face. He seemed easy-going and lazy during the day, but when it came to professional knowledge, he seemed serious and energetic.
Li Jiuyun stood aside, operating the computer, ready to supplement Lin Ling at any time.
But Wang Ao and Chen Mengtong were slightly embarrassed and indescribably complicated.
Now they are basically equivalent to outsiders, they are "hugging thighs".
This feeling, frankly speaking, is very uncomfortable.
However, although they had roughly read the thesis completed by Lin Ling and Li Jiuyun, more than half of it was their knowledge blind spot, and this defense was indeed beyond their ability.
Listening to Lin Ling's explanation, the instructor below nodded slightly.
This research topic is not particularly novel and difficult, but it is definitely not bad.
Then, Lin Ling continued to explain the content of his thesis.
"The first step is to extract by 95 ethanol percolation. After the extract is concentrated, the extract is obtained with petroleum ether, ethyl acetate and n-butanol."
"after."
All kinds of professional terms in Lin Ling's mouth emerged one after another, and professional knowledge seemed to be at his fingertips, showing his strong knowledge background.
Wang Ao and Chen Mengtong kept silent, this is indeed not the level that they can participate and show.
"Study hard, one day I want to be like Senior Brother Lin Ling!" Wang Ao took a deep breath, and after the frustration, came a strong motivation and motivation to learn.
Chen Mengtong was the same, his mood was not calm.
In this way, the explanation lasted for about 15 minutes. In the middle, Lin Ling and Li Jiuyun occasionally crossed explanations to complement each other.
The scene played out quite well.
Lin Ling answered the few questions raised by the instructors with ease.
After all, this is just a defense, and many relevant data cannot be verified on the spot.
And there are still teams queuing up behind, so the time is being compressed as much as possible.
"This is the end of this group's report. Thank you, teacher, for coming to listen." Lin Ling bowed deeply and let out a breath. There was also sweat dripping from his forehead, but there was a smile on his face. This time he played well.
Based on his past experience in competitions.
As long as the top three of the knowledge test group can be a little higher, it should not be difficult to win the first prize.
"Not bad." Several other teachers nodded slightly, affirming their research and defense.
Just when everyone thought that this defense was coming to an end.
The bald old man sitting in the middle suddenly said, "He Liang, do you have anything to add? What do you think of your group's experimental research?"
One word stirred up a thousand waves.
The goal is straight to the point!
Lin Ling was also taken aback.
Usually when doing a thesis, the teacher will not point to a student individually to ask questions!
"Bad thing!"
Their hearts sank suddenly.
If He Liang can't answer, it's not that he's revealing something, it's just that the teachers' impression of them will definitely decrease, and the scores will be lower.
He Liang was also quite surprised.
The bald old man in the middle has a serious face and reveals the temperament of an old scholar.
But... I don't even know him!
Why just point yourself?
However, He Liang soon reacted.
The corners of his mouth were raised slightly, with a calm demeanor: "The main part of this thesis report was completed by Senior Brother Lin Ling and Senior Brother Li Jiuyun. It is of great learning value for me, a freshman freshman."
First, express your attitude.
Immediately, He Liang continued: "However, in the second process, that is, when the antisulfur activity is located, I think the separation effect by chromatography will be better."
Several tutors quickly looked at the thesis manuscript in their hands.
The bald teacher's eyes lit up slightly: "Continue."
He Liang smiled, and then continued: "Firstly, the purple sweet potato powder is extracted with 95% ethanol under reflux, and the system in which the active ingredients are located is determined through in vitro activity experiments. Afterwards, the active parts are separated by chromatography and thin-layer chromatography. , spectroscopic detection."
He Liang stood on the stage, but all eyes focused on him following his speech.
Both Lin Ling and Li Jiuyun were stunned.
He Liang proposed another better solution!
The steps are simpler and the test results are more accurate.
"Then why didn't you tell us?"
"No! He Liang refrained from saying anything!"
"When he joined our team, he was only a few days away from the defense. Even if he told us this method, we didn't have time to re-test and finalize it!"
They were shocked.
"He Liang has considered this point!"
Can't help but feel a little touched.
Because, He Liang obviously gave "face" to their two senior brothers.
If He Liang raises it, it may make them anxious, feel that it is not the best solution, and "kill obsessive-compulsive disorder".
But this is not something everyone can do.
They saw a lot of first-year students, and they murmured everywhere when they researched something, eager to show their self-esteem and level.
And He Liang, very mature!
Slightly stunned, He Liang continued to explain with several mentors: "Finally, RT-PCR method is used to infer the anti-cancer mechanism of a certain compound monomer or a certain substance group."
"We came up with it later, so we don't have time to re-do relevant experiment reports." He Liang explained with a smile.
There is no claim of credit or pride in the words, and it is also called "we".
"I have a question." The bald teacher looked excited and discussed with He Liang.
He Liang smiled and answered his question after a little thought.
The two asked and answered, and the content was completely beyond the outline!
Wang Ao and Chen Mengtong were completely stunned!
"He Liang. Isn't he a freshman just like us?!"
They couldn't understand at all, why did He Liang know so much?
It's as if I have done countless experiments myself!
In the back, they have never even heard of many proper nouns!
Don't even know what to discuss!
level, the gap is too big!
Even Lin Ling was a little dazed at the moment, and even he had only read relevant information in a few reference books.
What He Liang blurted out was to discuss with the instructor below!
Shock!
The four people in a team are all numb!
And at this time, they also suddenly remembered something!
"He Liang's knowledge test in the afternoon took just over an hour to go out!"
He definitely can't!
That leaves just one more horrific answer!
He really finished everything and left the classroom on his own initiative!
He didn't give up, but he really finished writing it all? !
